Guide to Transportation Planning Data Sources

This is a guide to an array of transportation planning data sources of interest to the VTRC Transportation Planning Research Advisory Committee (TPRAC).

Bluetooth/WiFi Travel Times

Bluetooth and WiFi Travel time data sources are vendor specific and may require users to register and maintain individual usernames and passwords. 

Data of interest to TPRAC: Travel time and speed data on corridors that have been instrumented 

Some examples of this type of data source include:

 "BlueTOAD" by TrafficCast  

BlueToad Requires registration: *register here*


Acyclica's Go

VaTraffic App


VaTraffic is a web-based application that provides VDOT operations staff with the foundation they need to collect, monitor, update, and publish roadway information more efficiently. 
The VaTraffic application collects and distributes critical operational data in real-time. VDOT staff and contractors enter and maintain data and information about traffic incidents, work zones, weather events like fog and high wind advisories, security events, and major public events such as NASCAR races. More importantly, VaTraffic is the coordinating point for major emergencies including snow storms, flood events and hurricanes.
Virginia motorists benefit from access to timely traffic and travel information, and VDOT benefits from consistent, accurate, and real-time data required to meet its business needs and motorist’s expectations.

Data of interest to TPRAC: Statewide historic incident, work zone and weather data (need approval and training)

Data of interest to TPRAC: Road-user reports

VDOT RNS (Network Only)

The RNS creates a replacement system for the aging HTRIS mainframe system. The new system will incorporate a relational database that provides universal enterprise data access, links geospatial data and business attributes to the roadway centerlines, and provides web accessibility to users currently unable to retrieve critical roadway data.

The RNS is designed to be available to all VDOT personnel, such that they can view and report on a wide variety of VDOT business data through the application. Select users have the ability to perform more complex analyses and reporting.

Data of interest to TPRAC: Crashes

To view these and other resources on the VDOT RNS Site users will need to download Microsoft Silverlight

VDOT Crash Analysis Tool (Public)

The VDOT Crash Analysis Tool has been developed in-house by VDOT's Traffic Engineering Division, Highway Safety section for crash analysis purposes. The main source of the data is owned and maintained by the Virginia Division of Motor Vehicles (DMV). This site was made publicly available on October 23, 2019 and contains data from 2015-present. An overview video on this tool is available here.

Data of interest to TPRAC: Crash data, police reports


Treds logo

The main goal of TREDS (Traffic Records Electronic Data System) is to provide accurate, timely and detailed highway safety information for analysis and reporting. The data from TREDS is used to support Virginia’s efforts to reduce crashes, injuries, fatalities and associated costs. Through TREDS, Virginia now has one of the most effective and innovative information technology tools in the nation to identify and address its highway safety concerns. 

This state-of-the-art, automated data system centralizes all of Virginia’s crash data and related information. A recent enhancement to the system’s mapping tool, now allows users to combine safety program areas, such as impaired driving and speed, and it also allows agencies to focus on the crash data in their jurisdiction whereas in the past, users have only been able to narrow the data down to the county level.

Data of interest to TPRAC: Crash data, police reports



Dedicated to achieving the highest standards of excellence in motor vehicle and highway safety, NHTSA works daily to help prevent such crashes and their attendant costs, both human and financial.

NHTSA provides a number of data resources (featured below) of interest to TPRAC including FARS, NASS, NCSA, and STSI among others. 

FARS is a nationwide census providing NHTSA, Congress and the American public yearly data regarding fatal injuries suffered in motor vehicle traffic crashes.

Data of interest to TPRAC: Fatality data and queries

NASS logo

NASS provides NHTSA an efficient and reusable resource with which to conduct data collection representing a broad spectrum of American society. Using a core set of crash data components, NASS has proven a reliable resource for a variety of agency sponsored electronic data collection efforts over the past 10 years.

NASS is composed of two systems - the Crashworthiness Data System (CDS) and the General Estimates System (GES). These are based on cases selected from a sample of police crash reports. CDS data focus on passenger vehicle crashes, and are used to investigate injury mechanisms to identify potential improvements in vehicle design. GES data focus on the bigger overall crash picture, and are used for problem size assessments and tracking trends.

Data of interest to TPRAC: National crash statistics and estimates

The National Center for Statistics and Analysis (NCSA),  is an office of the National Highway Traffic Safety Administration (NHTSA),and is responsible for providing a wide range of analytical and statistical support to NHTSA and the highway safety community at large.

Data of interest to TPRAC: Records of all crashes and disengagements of autonomous vehicles


RITIS logo

The Regional Integrated Transportation Information System (RITIS) is an automated data sharing, dissemination, and archiving system that includes many performance measure, dashboard, and visual analytics tools that help agencies to gain situational awareness, measure performance, and communicate information between agencies and to the public.Learn More.

Data of interest to TPRAC:Incident and work zone data; detector data

***RITIS requires users to register for & maintain a username and password***

RITIS Vehicle Probe Project Suite

The RITIS Vehicle Probe Project Suite allows agencies to support operations, planning, analysis, research, and performance measures generation using probe data mixed with other agency transportation data.

The suite consists of a collection of data visualization and retrieval tools. These web-based tools allow users to download reports, visualize data on maps or in other interactive graphics, and even download raw data for off-line analysis. Each tool has its own unique purposes. Among many other uses, the Vehicle Probe Project Suite can provide insight on:

  • Real-time Speed Data
  • Travel Time Index
  • Travel Time Reliability metrics
  • Queue Measurements
  • Statewide bottleneck ranking
  • Corridor Congestion Chart

Learn more.


Data of interest to TPRAC:INRIX and NPMRDS TMC speed, congestion scans, performance charts, user delay costs, buffer time index, planning time index, bottlenecks, trend maps
