To cancel and close the dialog, press the Cancel button. RunSpec is MOVES run specification file in XML format. Once a RunSpec file is im- ported, additional data still needs to be specified such as PDM tables. 6.2. MOVES WIZARD Under the MOVES Options screen, you can click on the MOVES Wizard icon in order to navigate thought the MOVES Wizard. Buttons available under the MOVES INPUT DATA section will only become enabled after data has been completed in this part of the Wizard.

TRAQS User Guide Page 68 6.3. MOVES WIZARD – CONFIGURATION The MOVES Wizard – Configuration page contains the following options:

TRAQS User Guide Page 69 Model Settings The US EPA MOVES program is very extensive and can be setup to run in several domain scales, calculation types, and time aggregation levels. TRAQS was designed to support the following model settings:  Domain/Scale: Project Level The project scale allows the user to perform micro-scale analysis of roadway link emissions or off-network links where emissions from vehicles starts or extended idle activity occur. Project scale can be used for quantitative hot-spot analysis for CO, PM2.5, and PM10. The US EPA MOVES program also allows for other Domain/Scale options such as the National scale and the County scale which are not supported by TRAQS.  Calculation Type: Inventory TRAQS only supports the Inventory calculation type which provides emissions estimates as mass, using VMT and vehicle population entered by the user. The US EPA MOVES program supports an additional type of calculation "Emission Rates". The Emission Rates option, not supported by TRAQS, provides emission rates as mass per unit of activity.  Type of Day: Weekdays TRAQS only supports Weekdays. The US EPA MOVES program also supports weekend days. For project-level conformity analysis, the selection of Weekday is recommended.

TRAQS User Guide Page 70  Time Aggregation Level: Hour TRAQS only supports the Hour aggregation level which will calculate emissions for each hour of a day based on the specific inputs for that hour (e.g., temperature, speed distribution, etc.). The US EPA MOVES program supports other time aggregation levels such as year, month, and day, however, as noted these options are not supported in TRAQS. Geographic Bounds You must specify the State and County where your project is located.  State: Select from the drop-down list the state where the project domain is located.  County: Select from the drop-down list the county where the project domain is located. Analysis Year This is the year of the analysis and it will show the year that you selected under the New Project Wizard. However, you will be able to modify your selection in this screen. TRAQS can model calen- dar years 1990 and 1999 to 2050, inclusive. You can only model a single year per project. Users who want to model multiple calendar years will need to create multiple TRAQS projects. Analysis Type This section will show the analysis type selected under the New Project Wizard. This selection can be changed under the TRAQS Options window. MOVES Wizard - Configuration page

TRAQS User Guide Page 71 When finished, click on the Next button to proceed to the next step of the wizard. 6.4. MOVES WIZARD – SCENARIOS The MOVES Wizard – Scenarios page contains the same options available under the New Project Wizard – Project Scenarios screen.

TRAQS User Guide Page 73 6.5. MOVES WIZARD – FUEL & VEHICLE TYPE The MOVES Wizard – Fuel & Vehicle Type page allows you to specify the fuel-vehicle type com- binations to be included in the MOVES run scenarios. MOVES allows you to select from among 13 "Source Use Types" which is the terminology that MOVES uses to describe vehicle types. Users must select the appropriate fuel and vehicle type combinations to reflect the full range of vehicles that will operate on the roadway links and off-network links being analyzed in the MOVES run sce- narios. How to Specify Fuel–Vehicle Type Combinations 1. From the Fuels list, select all the fuels that should be included in the analysis. 2. From the Vehicle Types list, select all the vehicles that should be included in the analysis. 3. Press the button to add your selections to the Selected Fuel–Vehicle Type Combinations list. Make multiple selections from each list while holding down the Alt+Ctrl keyboard keys. The numbers between square brackets under each item on the 3 lists (e.g., [1], [21], [1-21]) are MOVES numerical identifies for fuel type (fuelTypeID) and vehicle type (sourceTypeID). For example, gasoline is 1 and passenger car is 21.

When finished, click on the Next button to proceed to the next step of the wizard – Project Data Manager (PDM). 6.8. MOVES WIZARD – PROJECT DATA MANAGER (PDM)

TRAQS User Guide Page 78 The MOVES Wizard – PDM page contains the following options: Traffic Activity Approach In MOVES, activity on roadway links can be defined by one of the available modes:  Average Speed: This approach allows the MOVES model to calculate emissions based on a default drive cycle for a given average speed, volume, grade, and road type on the specified project's link. This approach accounts for some differences in emissions due to changes in operating modes associated with different average speeds on a specific road type. In com- parison with the other approaches, this one provides the least resolution when analyzing the emission impact of a project because the default drive cycles used by the model may not ac- curately reflect the specific project. For example, a single average speed may not spatially capture localized idling and acceleration emissions due to the range of operating modes as- sociated with intersection projects.  Link Drive Schedule: This approach allows the user to define the precise speed and grade as a function of time on a particular roadway link. The time domain is entered in units of seconds, the speed variable is miles-per-hour and the grade variable in percent grade (verti- cal distance/lateral distance). Link drive schedules will only represent average vehicle activ- ity, not the full range of activity that will occur on the link. To overcome this limitation, the user can define multiple links for the same portion of the project (i.e., "overlapping" links) with separate source distributions and drive schedules to model individual vehicles.  Operating Mode: This approach allows the user to directly specify operating mode fraction data for source types, hour/day combinations, roadway links, and pollutant/process combi- nations that are included in the MOVES run specification.

TRAQS User Guide Page 79 Functionality of Buttons Populates all PDM tables, for all scenarios, with option to autofill with default MOVES database data.

How to Populate PDM Tables: 1. The first time the MOVES Wizard – PDM screen is displayed, all the PDM tables for all scenar- ios will be empty. The icon is displayed, under the Scenario Tree list, indicating which PDM tables are empty. 2. Press the button. The Generate All Options dialog is displayed. TRAQS popu- lates the PDM tables with 2 types of data:  Fixed Data Fields: This data is populated based on the selections you made under the New Project Wizard, Map & Links module, and MOVES Wizard. Examples of such data are: Analysis Year, Source Types, Fuel Type, Link Parameters, etc.  Variable Data Fields: This is the data specific to the region you are modeling. For ex- ample, temperature, relative humidity, source age fractions, source type fractions, etc.

TRAQS User Guide Page 81 Some of these fields can be auto-filled with data imported from the MOVES default data- base by checking the Auto-fill box in the message that is displayed (see image below). Check the Auto-fill box to import data from the default MOVES database. It is recommended that you replace this imported data with your site-specific data by using the Export and Import options. 3. Once the process of populating the PDM tables finishes, you may see, under the Scenario Tree list, one or more of the following status icons: Complete: Indicates the PDM table has been completely populated with data. Incomplete: Indicates the PDM table has some cells that still needs to be populated with data. Modified: Indicates the PDM table needs to be re-generated as some of the existing "Fixed Data Fields" are no longer valid. This status occurs for example, if you modified any links, vehicle types, fuels, analysis year, scenarios, etc., but did not re-generated the PDM table(s). Empty: Indicates the PDM table is completely empty.

TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 246: Volume 1: TRAQS User Guide provides guidance for using the TRansportation Air Quality System (TRAQS). TRAQS is an open source software designed to conduct mobile air quality assessments for three primary purposes:

  1. Project-Level Conformity (Hot-Spot Analyses)
  2. National Environmental Policy Act (NEPA)
  3. General Transportation Planning

TRAQS is designed to streamline the model process and minimize any limitations of standalone software packages by integrating individual models and databases into a user-friendly, intuitive Graphical User Interface. It provides access to advanced modeling tools and mapping features. Overall, TRAQS offers the capabilities necessary to complete a Project-Level air quality analysis with increased accuracy and efficiencies.

Download the open source software as well as NCHRP Web-Only Document 246: Volume 2, TRAQS: A Combined Interface for Project-Level Air Quality Analysis, which accompany the Users Guide.

Note: TRAQS functions with versions of air quality models current as of December 2016: MOVES2014a and EMFAC2014.

TRAQS is written in Python, an open-source programming language. Developers or users who wish to customize or enhance TRAQS may download the source code from the project web page.
