7 Model Inputs

Once a VisionEval model has been installed, a directory with sample data will be available within the model directory (e.g., ../models/VERSPM/ where .. refers to the parent directory of the unzipped installer file). See VisionEval walkthrough files for instructions on installng sample models.

The model directory serves the dual purposes of providing sample data and a template for local modification to other locations.

The default VERSPM directory contains sample input files for the Rogue Valley region in Oregon, while the default VE-State directory contains sample input files for the State of Oregon. These inputs will be modified or replaced to investigate the impacts of policy changes or to model a different region.

7.1 Standard Model Structure

VisionEval models all have a standard structure, which can be customized. The typical structure is described here.

The visioneval.cnf in the model directory defines the model’s structure. It is introducted in Model Configuration.

The defs directory contains three model definition files which are introduced in Set-Up Inputs section.

The inputs directory contains a number of CSV and JSON files that provide inputs for the modules. Each module specifies what input files it needs. The majority of input files are CSV formatted text files. The names of the file identify the geography level for the input data. For example, azone_hh_pop_by_age.csv is the input for household population by age, and should have data at the Azone level. Each input file has:

  • Field names identifying dataset names
  • Year field when inputs vary by model year
  • Geo field when inputs vary by geography

Field names can also have modifiers, such as the year that money values are denominated in (e.g. 2010) or magnitude multiplier for large numbers (e.g. 1e3). Input specifications, which can be located in the source code for each module as well as the module documentation, can be referenced when users are unsure of the input data type, units, and any prohibited values. In formatting input files, users should pay attention to the following:

  • Need values for every combination of year and geography
  • Field names must exactly match specifications
  • Values must match specification data type and not contain any prohibited values
  • No data for years other than model run years
  • No data for areas other than those defined in geo.csv file

The rest of this section will contain generalized best practices for input development applicable to all VisionEval models and go into the details of inputs for each model.

7.2 Model Configuration (visioneval.cnf)

This file contains parameters that define key attributes of the model and its computational stages and scenarios. This file can be in YAML format (typical) or JSON (for backward compatibility - it replaces run_parameters.json in older versions of VisionEval). Certain elements of visioneval.cnf need to be modified by the user to specify the model base year and run years. A more detailed description of the file is not currently available (but will appear soon). The typical contents of visioneval.cnf are as follows:

# Model-wide description
Model          : VE-State 3.0
Region         : Oregon                     # Change to your local area
State          : OR                         # Change to your local area
BaseYear       : 2010                       # Change to your model's base year
Script         : run_model.R

# Model Stages and Scenarios
ModelStages:
  base-year-2010:                           # Change base year stage name
    Years : [2010]                          # Change 2010 to your model's base year
    Description : Oregon Base Year 2010     # Change to correct description
  future-year-2040:
    StartFrom : base-year-2010              # Change to be consistent with base year stage name
    Years : [2040]                          # Change 2040 to your model's future year
    Description : Oregon Future Year 2040   # Change to correct description

See the separate scenarios section (under construction) to learn how to set scenarios up efficiently within models.

With this standard setup, model results will be generated in folder called results, and the model stages will each generate their outputs into a sub-folder of results named after the stage.

The model directory structure will look like the following, though the results directory won’t exist until you run the model:

VE-State-years # or whatever your model is called in the `models` folder
-- defs
   -- deflators.csv
   -- geo.csv
   -- units.csv
-- inputs
   ... all the `.csv` files plus `model_parameters.json` used in the model
-- results
   -- base-year-2010
      -- Datastore
         -- ... (Subfolders and files with the model outputs)
      -- Log_<run_date>....txt (model run notices, including warnings and errors)
      -- ModelState.Rda
   -- future-year-2040
      -- Datastore (folder)
      -- Log_<run_date>....txt
      -- ModelState.Rda
-- scripts
   -- run_model.R
-- visioneval.cnf

7.3 Model Script

The scripts folder contains one or more model scripts describing the sequence of VisionEval modules that the model will run to genereate its outputs. Typically, there will be one script called run_model.R but the name can be changed in visioneval.cnf.

Here is the standard run_model.R script for the VERSPM model. Generally, the script won’t be changed except for debugging purposes. One reason to change the script might be to use a locally customized package with a different name (e.g. VEMyPowertrainsAndFuels versus VEPowertrainsAndFuels).

7.4 Set-up Inputs

The set-up inputs are those in the defs directory. The geo.csv file will need to set up to represent the model geography. deflators.csv may need to be adjusted to ensure that all years prior to the model base year are present. units.csv typically will not need to be adjusted.

7.4.1 deflators.csv

This file defines the annual deflator values, such as the consumer price index, that are used to convert currency values between different years for currency denomination. This file does not need to be modified unless the years for which the dollar values used in the input dataset is not contained in this file. The format of the file is as follows:

Year Value
1999 172.6
2000 178.0
2001 182.4
… …
2010 218.344
… …
2015 244.19
… …
2020 271.52
2021 277.34

7.4.2 geo.csv

This file describes all of the geographic relationships for the model and the names of geographic entities in a CSV formatted text file. The Azone, Bzone, and Marea names should remain consistent with the input data. More information on developing this file and VisionEval model geographic relationships can be found here. The format of the file is as follows:

7.4.3 units.csv

This file describes the default units to be used for storing complex data types in the model. This file should NOT be modified by the user. The VisionEval model system keeps track of the types and units of measure of all data that is processed. More details about the file and structure can be found here. The format of the file is as follows:

Type Units

7.5 Inputs by Concept

This section covers generalized inputs by concepts shared by all VisionEval models. Best practices for inputs by concepts are also discussed. To learn about the specific inputs used by each model skip ahead to the following sections:

7.5.1 Household Synthesis Inputs

The demographic and land use inputs are those related to population, employment, and income that result in the household synthesis. VisionEval takes user input statewide population by age group, assembles them into households with demographic attributes (lifecycle category, per capita income).

  • Pool of available households. Modelwide, Census PUMS data represents actual households and representative mix of household composition and demographics for your area it is built into the code. Note that users must rebuild the VESimHousehold package to use local PUMS data as Oregon data is the default, see the chapter on Estimation in VisionEval for instructions on how to rebuild packages.

  • Population by age control totals. For population inputs, VisionEval models distinguish between the regular household population and group quarter population due to distinct differences in travel behaviors. Zone-level inputs for (1) regular households and (2) group quarters households (can be 0) include population by age group and average per capita income. Base year totals for the household population can be obtained from Census. Future year forecasts should be consistent with but may need to be extrapolated beyond adopted regional plans (e.g., RTP, County and City TSPs). Some local governments may have detailed age information generated as part of a Housing Needs Analysis completed for the Periodic Review of the local Comprehensive Plan. If not, future population by age can apply ratios from the base year model set-up. Group quarters population data is best obtained from the university administration, by age if possible. Group quarters can be approximated from enrollment data by class year. All other group quarters data (e.g., income) are difficult to obtain but not of paramount importance to the model, simplifying assumptions are often required. Per capita income can be obtained from either the Census or Bureau of Economic Analysis. Since the model accounts for inflation, future income can remain the same in future years, or adjusted based on local plans.

  • Optional household adjustments. (Optional) constraints on regular households include average household size and proportion of single-person households, adjustments to licensure rate for driving age persons. Household size values can be obtained from the Census and licensure data can be obtained from the state DMV.

  • Employment. VERSPM employment inputs require employment by type in each model year by Bzone. VE-State requires workers by location type (Optional) constraints on aggregated employment rate for working age persons by Azone.

7.5.2 Land Use Inputs

Once households are synthesised, VisionEval allocates them to Bzone-level dwelling units inputs. Separately Bzones are attributed with employment and land use attributes (location type, built form ‘D’ values, mixed use, employment by type). Household members are identified as workers and/or drivers and number of household vehicles are estimated. Each home and work location is tied to a specific Bzone with its associated attributes. Additionally, some local policies are land use based.

  • Dwelling units. Numbers of dwelling units by type in each model year and proportions of each in each development type. Income quartiles tied to households in dwelling units help VisionEval assign households to a compatible Bzone location. The base year dwelling unit data can sourced from either the Census or an available travel demand model. Future year dwelling units can be obtained from local Comprehensive Plans. Adjustments may be needed to count only occupied units, and occupancy rates can be obtained from Census block group data, as a starting point. Base and future year dwelling unit counts should be consistent with household assumptions in the region’s travel demand model.

  • Land use. Inputs set the total developable land area, by development type. VERSPM also requires its location (centroid latitude-longitude) for spatially linking to source data, and input assumptions on the built form measures. These inputs can change by model run year. Some land use data use EPA Smart Location Database (SLD) data. Geospatial SLD data can be downloaded at the block group level and extrapolated to other geographies if needed using just used the EPA block group data.

  • Land use-household linkages. VisionEval assigns a Bzone to each household’s home and to each household worker’s work location, with the associated Bzone attributes. The VisionEval-calculated urban mixed use designation of the Bzone can optionally be modified by input targets on the proportion of households assigned that designation in each Bzone in this process.

    • Note: Input files must be consistent. This includes: (1) land area must be specified for each azone location type that has households or employment assigned to it; (2) dwelling units must be a reasonable match with population (divided by household size); (3) shares of jobs within each Azone must sum to 1 for all Azones in the Marea.

7.5.2.1 Defining “Location Type” (metro, town, rural)

One method is to define land in MPO boundaries to be metro, for urban areas smaller than MPOs, land inside their UGB is a town. Everything else is rural. Note that if you want to further refine within the MPO, place types can identify low density areas that you might consider “rural” and areas that less accessible/more isolated (don’t have access to broader transit service) as “town”. Some states have official population forecasts done for each urban area that helps with the population inputs. Users can also use LEHD where we used the boundaries identified above to designate location types, and then used LEHD to calculate worker flows between county home location-to-work LocType (any county).

An alternative method is to use the Census Urban and Rural Classification. The Census Urban and Rural Classification distinguishes between two types of urban areas:

  • Urbanized Areas (UAs) of 50,000 or more people are defined as metro
  • Urban Clusters (UCs) of at least 2,500 and less than 50,000 people are defined as town
  • Everything else is rural

**NOTE: the 2020 Census has removed the Urban Cluster specification.

7.5.2.2 Defining “Area Type” (center, inner, outer, fringe)

“Area Type” is based on a mix of activity density levels and destination accessibility levels, as discussed in the documentation discussing the VE-State EAP-SLD-based Bzone synthesis.

ODOT develops place types using data from local travel demand models, specifically TAZs within MPOs (Mareas). Area type VisionEval inputs are generated using population and employment data by TAZ using the below calculations. By using local travel model TAZ data which has base and future population and employment, users can create a future version of these variables and thus the VE-State area type inputs we calculate cover different areas over time:

  • Activity Density = TAZ-level (population [households and qroup quarter units] + employment / 2.5) / unprotected acres [with parks and water removed). SLD variable D1B is roughly the same.
  • Destination Accessibility = TAZ-level as shown below. There’s not an equivalent SLD attribute, but some of the D5 attributes are similar.
    • (D5) Harmonic mean of employment within 2 miles and population within 5 miles (2 * TotEmp_InDist2mi * Pop_InDist5mi) / (TotEmp_InDist2mi + Pop_InDist5mi).
    • Levels: VL = 0 - 2e3, L = 2e3 - 1e4, M = 1e4 - 5e4, H = 5e4+.
  • Design = SLD variable D3bpo4

7.5.3 Household Travel Behavior Inputs

Many of the inputs relating to household multi-modal travel are those that also can serve as policy levers to be tested in multi-run scenario exercises. Users should work with stakeholders to refine these values and finalize reference scenario inputs that reflect financially constrained adopted plans in their area. These discussions with local staff also start to define more/less ambitious scenarios to include in the multi-run scenario modeling.

  • Transport supply (Mareas only) Unlike traditional travel demand models, VisionEval does not have a roadway network. The inputs for transportation supply define roadway capacity in terms of lane miles of arterials and freeways and transit service miles (annual revenue service miles) for each transit service mode) for the urbanized area portion of each Marea by model run year. A separate Bzone-level input sets neighborhood transit accessibility or Transit D. For lane-miles in the model area, HPMS is the standard source. Users can use use the lane-length values as lane-mile inputs, aggregating as follows:

    • Fwys = “Interstate”& “Other Freeways & Expressways”
    • Arterials = “Other Principal Arterial” & “Minor Arterial”
    • Major/Minor collectors and local streets are not included

  • Personal short trips/alternative modes. VisionEval inputs define policies for transit, bike and walk modes. These include transit service levels and transit accessibility (Transit D) per transit supply above. Biking trips are defined by the proportion of short-trip SOV diversion (20 miles or less round-trip). Walk while walk trips are dependent upon mixed-use development and built form design and measures.

  • Travel demand management (TDM). Each household is assigned as a participant or not in a number of travel demand management programs (e.g. employee commute options program, individualized marketing) based on policy assumptions about the degree of deployment of those programs and the household characteristics. Individual households are also identified as candidate participants for car sharing programs based on their household characteristics and input assumptions on the market penetration of car sharing vehicles.

    • Workplace TDM Programs. Level of deployment assumptions for TDM (at work and home locations) lead to reduced VMT, diverting travel to other modes. Car Sharing reduces VMT through changes in auto ownership and per mile costs. Employee commute options (ECO) programs are work-based travel demand management programs. They may include transportation coordinators, employer-subsidized transit passes, bicycle parking, showers for bicycle commuters, education and promotion, carpool and vanpool programs, etc. The default assumption is that that ECO programs reduce the average commute DVMT of participating households by 5.4%. Users can modify this value but it requires rebuilding the VELandUse package for VERSPM or VESimLandUse for VE-State. It is assumed that all work travel of the household will be reduced by this percentage if any working age persons are identified as ECO participants. The proportion of employees participating in ECO programs is a policy input at the Bzone-level in VERSPM and either the Azone or Marea level in VE-State. The input assumes workers participate in a strong employee commute options programs (e.g., free transit pass, emergency ride home, bike rider facilities, etc.).
    • Individualized Marketing TDM Programs. Individualized marketing (IM) programs are travel demand management programs focused on individual households in select neighborhoods. IM programs involve individualized outreach to households that identify residents’ travel needs and ways to meet those needs with less vehicle travel. Customized to the neighborhood, IM programs work best in locations where a number of travel options are available. VisionEval assumes that households participating in an IM program reduce their DVMT by 9% based on studies done in the Portland area. Users can modify this value but it requires rebuilding the VELandUse package or VESimLandUse for VE-State. IM programs target work as well as non-work travel and produce larger reductions than ECO work-based programs. Only the IM reduction is used for households that are identified as participating in both ECO and IM programs. The VisionEval input for IM programs include an overall assumption for the percentage of households participating in an IM program. A minimum population density of 4,000 persons per square mile necessary to implement a successful IM program and the requirement that the household reside an urban mixed use Bzone. The number of households identified as participating is the minimum of the number needed to meet the program goal or the number of qualifying households.

  • Parking. Parking in VisionEval is defined by parking supply and parking restrictions, including parking costs.

7.5.4 model_parameters.json

This input file contains global parameters for a particular model configuration that may be used by multiple modules. A more detailed description of the file and its structure can be found here. The source of the default \(16/hr in 2010\) was derived from a Nov 2014 Oregon DOT Report: “The Value of Travel-Time: Estimates of the Hourly Value of Time for Vehicles in Oregon”. Note the input looks for the dollars in the year of the base model.

The format of this file is as follows:

[
  {"NAME": "ValueOfTime", 
   "VALUE": "16", 
   "TYPE": "double", 
   "UNITS": "base cost year dollars per hour"
  }
]

7.5.5 Vehicle, Fuels and Emissions Inputs

Vehicle and fuel technology are expected to change significantly during the next several decades as vehicles turn-over and the newer fleets are purchased. The characteristics of the fleet of new cars and trucks are influenced by federal CAFÉ standards as well as state energy policies and promotions. Local areas can contribute through decisions about the light-duty fleet used by local transit agencies and by assisting in deployment of electric vehicle charging stations and their costs in work and home locations, but otherwise have less influence on the characteristics of the future vehicle fleet, including auto, light truck, and heavy truck vehicles. As a consequence, the VisionEval inputs on vehicle and fuel technology are largely specified modelwide at the region level. These inputs can be used to assess the impacts of changing vehicle powertrains and fuels on energy use and GHG emissions in the model area. The key local contribution to these inputs is the bus powertrain and fuels inputs, which are defined by metropolitan area (Marea) although defaults can be used if no additional local data is available. These variables are briefly summarized below.

  • Powertrains. Several input files specify vehicle attributes and fuel economy for autos, light trucks, heavy truck, and transit vehicles. User inputs modify vehicle powetrains for commercial service vehicles, car service vehicles, transit vehicles, and heavy trucks. Changing the powertrain mix of household vehicles involves rebuilding the VEPowertrainsAndFuels package. Four vehicle powertrain types are modeled:

    • ICE - Internal Combustion Engines having no electrical assist;
    • HEV - Hybrid-Electric Vehicles where all motive power is generated on-board;
    • PHEV - Plug-in Hybrid Electric Vehicles where some motive power comes from charging an on-board battery from external power supplies;
    • EV - Electric Vehicles where all motive power comes from charging an on-board battery from external power supplies.

  • Household owned vehicles. Household vehicle characteristics are defined by Azone and model run year to account for regional trends. Characteristics include the passanger fleet share by vehicle type (light truck or auto) and average vehicle age. The purpose of these inputs is to allow scenarios to be developed which test faster or slower turn-over of the vehicle fleet or test fleets mixes in terms of passenger autos and light trucks or SUVs, both of which impact fuel economy. Users also define the availability of residential electric vehicle charging stations at the Azone level by dwelling unit type and model run year. Vehicle type and age characteristics combine with powertrain sales by year defined in the VEPowertrainsAndFuels package. Each powertrain in each year has an associated fuel efficiency and power efficiency assumptions for PHEVs (MPG for PHEVs in charge-sustaining mode). For EVs and PHEVs, battery range is specified. Note that the actual EV-HEV split depends on whether enough households have their 95Th percentile daily travel within the EV battery range

  • Car service vehicles. Car services are a specific mode used in VisionEval models treated as vehicles available to the household. Car services can be considered a synonym for popular ride-sharing services provided by mobility-as-a-service (MaaS) companies. VisionEval distinguishes between two levels of car service, categorized as “high” or “low” level service. A high car service level is one that has vehicle access times (time to walk between car and origin or final destination) that are competitive with private car use. High level of car service is considered to increase household car availability similar to owning a car. Users can define the car service substitution probability by vehicle type. Low level car service, approximates current taxi service does not have competitive access time and is not considered as increasing household car availability. Users can define different attributes for each level of car service. Users can define several characteristcs of car service by level, including cost per mile by car service level, average age of car service vehicles, and limits on household car service substitution probability for owned vehicles. Region-level inputs on powertrain mix by model (not sales) year and (optional) region-wide composite fuel carbon intensity.

See the section on Pricing, Household Costs & Budgets inputs for more information on car service levels, geographic coverage, and fees. See the Vehicles, Fuels & Emissions inputs section for more information on defining the car service fleet powertrain characteristics.

  • Transit. Transit vehicles characteristics are defined by Marea and model run year for transit vehicle type(van, bus, rail), including powertrain mix by model (not sales) year and optional detail on fuel-biofuel shares. Users can also optionally define region-wide composite fuel carbon intensity by transit vehicle types.

  • Freight vehicles (heavy trucks and commercial service). Commercial service vehicle vehicle characteristics are defined by Azone and model run year, including vehicle type shares and average vehicle age. (optional) Region-wide composite fuel carbon intensity by vehicle type. Heavy truck vehicle characteristics are region-level, including powertrain mix and composite fuel carbon intensity by model (not sales) year.

  • Electric carbon intensity. Since electricity generation varies by locality, users can define the electricity carbon intensity at the Azone-level. This impacts GHG emission rates (in average pounds of CO2 equivalents generated per kilowatt hour of electricity consumed by the end user) by local area.

  • Fuel input options. Three options are available for fuel assumptions. The choices are outlined in the table and options described below. User choice of option can vary by vehicle group and where applicable, vehicle type:

  1. Default package datasets. These may represent federal or statewide fuel policies that apply to all metropolitan areas and all vehicle groups in the model (e.g., state ethanol regulations). NAs would be placed in all user input files.
  2. Detailed fuel and biofuel inputs. Values for the proportions of fuels types (gasoline, diesel, compressed natural gas), as well as fuel blend proportions (gasoline blended with ethanol, biodiesel blended with diesel, renewable natural gas is blended with natural gas). A third assumption specifies the carbon_intenaity of the fuels (input or default). For example, heavy trucks can be set to 95% diesel, 5% natural gas, with diesel having a 5% biodiesel blend.
  3. Composite carbon intensity. This option simplifies the process of modeling emissions policies, particularly low carbon fuels policies by bypasses the need to specify fuel types and biofuel blends. Average carbon intensity by vehicle group and if applicable, vehicle type is specified directly. These inputs, if present and not ‘NA’, supercede other transit inputs.
  • Note: Given that transit agencies in different metropolitan areas may have substantially different approaches to using biofuels, transit vehicles have the option of region or metropolitan area specifications for Options (1) and (2).
  • Note: The proportions in option (2) do not represent volumetric proportions (e.g. gallons), they represent energy proportions (e.g. gasoline gallon equivalents) or DVMT proportions.
  • Note: Individual vehicles are modeled for households. Other groups vehicle and fuel attributes apply to VMT. As a result, PHEVs in all but household vehicles should be split into miles driven in HEVs and miles in EVs.

7.5.6 Pricing, Household Costs & Budget Inputs

Most of these will be state-led actions and thus reflect the state policies of the modeled area.

  • Per mile vehicle out-of-pocket costs. Several inputs define the per mile costs used in calculating household vehicle operating costs that may be limited by the household’s income-based maximum annual travel budget. These inputs include those defining energy costs, car service fees, and fees to recover road and social costs, as noted below.

  • Energy costs. Unit cost of energy to power household vehicles, both fuel (cost per gallon) and electricity (cost per kilowatt-hour).

  • Car service fees. If car service is used by a household, the per mile fees paid for that service, outside of energy costs. Car service characteristics cost per mile by [car service level by Azone and model run year.

  • Road cost recovery VMT fee. Inputs include a fuel tax or levying a fuel-equivalent tax on travel by some/all electric vehicles (PevSurchgTaxProp), for their use of roads in lieu of gas purchases. User can also directly specify a VMT (mileage) fee, to further recover road costs, or optionally flag VisionEval to iteratively estimate the VMT fee to fully recover user-defined road costs incurred by household VMT.

  • Social cost recovery. (Optional) Inputs allow per mile fee to cover social costs or externalities, not recovered in this way today, but instead incur costs elsewhere in the economy (e.g., safety, health). This is the cost imposed on society and future generations, not the cost to the vehicle user. This requires assumptions on the cost incurred from these externalities (per mile, per gallon) and the proportion to be paid by drivers as a per mile fee (varies by vehicle powertrain). The Social Externality costs are specified in the VETravelPerformance package External Data files. The values are in 2010$. Click here for additional detailed explanation of on the way the costs are used in the model. See the PDF for externality research.

  • Per mile time-equivalent costs. Users can define the value of time, which is included in vehicle operating costs calculations. The model calculates travel time (model-calculated), which includes time to access vehicle on both ends of trip (between vehicle parking location and origin or end destination), multiplied by value of time.

  • Annual vehicle ownership costs. Vehicle ownership cost inputs are defined at the Azone-level by year. These inputs include annual vehicle fees (flat fee and/or tax on vehicle value), pay-as-you-drive (PAYD) insurance participation rates, residential parking limitations and fees, that are combined with model-estimated ownership costs (financing, depreciation, insurance).

  • Congestion Fees. Congestion fees are defined by Marea. The input is the average amount paid per mile in congestion pricing fee. The congestion fees are specified for each of the congestion bands in the model for both Arterial Congestion Fees and Freeway Congestion Fees.

7.5.7 Congestion Inputs

  • Base year VMT. Users provide can provide base year VMT (for both light-duty vehicles and heavy trucks) or use the model default by using a state/UzaLookup. Users also select a growth basis for heavy trucks of either population or income and for commercial service VMT (population, income, or household VMT). Users also provide the DVMT split of light-duty vehicles, heavy trucks, and buses on urban roads by road class. Values for UzaNameLookup must be present in the list provided in the module documentation, otherwise user inputs must specify the data directly.

  • ITS-Operational Policies. Users define the proportion of VMT by road class affected by standard ITS-Operation policies on freeways and arterials. Another optional input can define additional operations effects, providing flexibility for future user-defined freeway and arterial operations program coverage and effectiveness. These programs reduce delay. The specific ITS programs available in the model are the following:

    • Freeway ramp metering - Metering freeways can reduce delay by keeping mainline vehicle density below unstable levels. It creates delay for vehicles entering the freeway, but this is typically more than offset by the higher speeds and postponed congestion on the freeway facility. The Urban Mobility Report cites a delay reduction of 0 to 12%, with an average of 3%, for 25 U.S. urban areas with ramp metering. Only urban areas with Heavy, Severe, and Extreme freeway congestion can benefit from ramp metering in RSPM
    • Freeway incident management - Incident Response programs are designed to quickly detect and remove incidents which impede traffic flow. The UMR study reports incident-related freeway delay reductions of 0 to 40%, with an average of 8%, for the 79 U.S. urban areas with incident response programs. This reflects the combined effects of both service patrols to address the incidents and surveillance cameras to detect the incidents. Effects were seen in all sizes of urban area, though the impacts were greater in larger cities.
    • Arterial access management – Access management on arterials can increase speeds by reducing the number of enter/exit points on the arterial and reduce crashes by reducing conflict points. Although improvements such as raised medians can reduce throughput by causing turning queue spillback during heavy congestion, other types of access management, such as reduced business ingress/egress points, show consistent benefits system-wide.
    • Arterial signal coordination – Traffic signal coordination, particularly for adaptive traffic signals, can reduce arterial delay by increasing throughput in peak flow directions. UMR and other analysis estimates delay reductions of up to 6-9% due to signal coordination, with more potential savings from more sophisticated control systems. An average arterial delay savings was found to be about 1%.
    • Other ops programs – A separate input that gives users the ability to accommodate future enhancements. Further research and significant program investment would be needed to justify benefits in these enhanced ITS programs.

  • Speed smoothing programs. Proportion of VMT by road class covered by ITS speed smoothing, and Eco-drive programs. These programs reduce vehicle accelerations and decelerations, but do not affect delay.

    • Speed smoothing programs - Insufficient aggregate performance data is available for a number of other current and future ITS/operations strategies. These include: speed limit reductions, speed enforcement, and variable speed limits that reduce the amount of high-speed freeway travel; advanced signal optimization techniques that reduce stops and starts on arterials; and truck/bus-only lanes that can move high-emitting vehicles through congested areas at improved efficiency. Literature review of fuel efficiency improvements found that speed smoothing policies could only reasonably achieve a portion of the theoretical maximum of 50%, which is the ratio applied to the user input of full deployment (input of 1=100%).
    • Eco-drive programs Eco-driving involves educating motorists on how to drive in order to reduce fuel consumption and cut emissions. Examples of eco-driving practices include avoiding rapid starts and stops, matching driving speeds to synchronized traffic signals, and avoiding idling. Practicing eco-driving also involves keeping vehicles maintained in a way that reduces fuel consumption such as keeping tires properly inflated and reducing aerodynamic drag. In RSPM, fuel economy benefits of improved vehicle maintenance are included in the eco-driving benefit. A default 19% improvement in vehicle fuel economy is assumed. Vehicle operations and maintenance programs (e.g. eco-driving) based on policy assumptions about the degree of deployment of those programs and the household characteristics. Vehicle operating programs (eco-driving) reduces emissions per VMT at a max of 33% for freeways and 21% for arterials for full deployment (input of 1=100%).
