The Research Data Exchange (RDE) is a web-based data resource provided by the USDOT Intelligent Transportation Systems (ITS) Program. It collects, manages, and provides access to archived and real-time multi-source and multi-modal data to support the development and testing of ITS applications.
The RDE now houses the following three additional data environments:
- Basic Safety Messages (BSMs) sent by vehicles through either the cellular network or DSRC communications when the vehicle is in the range of Roadside Units (RSU).
- The queue warning messages that were recommended by the Q-WARN algorithm and sent to vehicles to warn drivers upstream of the queue.
- The speed harmonization messages that were recommended by the SPD-HARM algorithm and sent to vehicles to provide drivers with the recommended speed while driving in the roadway segment being monitored by the algorithm.
- The real-time infrastructure traffic sensor data collected from WSDOT’s detector station data files in a 20-second interval for the I-5 segments monitored by the INFLO algorithms.
Integrated Dynamic Transit Operation (IDTO)
The data sets are available from the prototype testing conducted in Columbus, OH in April 2014 on three IDTO applications: Connection Protection (T-CONNECT), Dynamic Transit Operations (T-DISP) and Dynamic Ridesharing (D-RIDE). The following data sets are available in the RDE:
- Data that relates to the providers who collectively represent or furnish the transportation supply to meet the transportation demand.
- Data that relates to the T-CONNECT ecosystem, which contains various components of the T-CONNECT application.
- Data that stores each traveler’s locations. This data is only stored if a traveler takes a trip with a T-DISP or T-CONNECT opportunity, and the traveler has selected to share his or her location using the mobile application.
- The Vehicles Data Set includes data sets that relate to the vehicles utilized during this observation.
The R.E.S.C.U.M.E. application bundle aims to advance the transmission of vehicle to vehicle safety messaging over dedicated short-range communications (DSRC) to improve the safety of emergency responders and travelers. R.E.S.C.U.M.E. is composed of the following three applications: Response Staging (RESP-STG), Incident Zone (INC-ZONE), and Emergency Communications and Evacuation (EVAC). The EVAC application was simulated but not prototyped. RESP-STG and INC-ZONE were prototyped and demonstrated at Columbus, Ohio and Sykesville, Maryland. Twelve scenarios illustrated the functionality of the RESP-STG and INC-ZONE applications, which were viewed from the perspectives of the transportation center, the responder and the oncoming Vehicle. The data included in the RDE is primarily the communication logs between the smartphone application and the research laptops. When the Laptop application is set active, there is a sequence of messages that show the laptop connecting to the different devices in the system. When the laptop makes a successful connection to the device, it is represented in the log.
Researchers, application developers, and others are invited to visit the RDE website to explore how they may use the available data and resources. For more information, please contact Jon Obenberger at jon.obenberger@dot.gov.
