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 following new data environments are now available for download: Intelligent Network Flow Optimization Simulation (INFLO SIM) is a VISSIM simulation model for the US 101 freeway corridor in San Mateo, CA. This model is used to assess the impacts of the INFLO Prototype Dynamic Speed Harmonization (SPD-HARM) application. This set of performance measure files was calculated based on the VISSIM outputs of 24 scenarios runs of the SPD-HARM […]

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: Intelligent Network Flow Optimization (INFLO) The two prototyped INFLO applications (speed harmonization (SPD-HARM) and queue warning (Q-WARN)) were demonstrated from January 12 through January 16, 2015 on a segment of I-5 in Seattle, WA. The purpose of this project was to demonstration the functionality and performance of these two prototype applications in an operational traffic environment. The following […]

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 four data sets from the Next Generation Simulation (NGSIM) Program. The NGSIM program was initiated by the United States Department of Transportation (USDOT) Federal Highway Administration (FHWA) to develop traveler behavioral algorithms that could be used in microscopic traffic simulation models. The validated data sets and documentation describing these algorithms which replicated the interactions of multimodal travelers, vehicles and highway systems (e.g., traffic control […]

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 two months of data from the Safety Pilot Model Deployment (SPMD) program. These sets of naturalistic driving data are a valuable resource for researchers and application developers to support the development of the next generation of transportation solutions. The data sets contain sanitized mobility data elements collected from about 3000 vehicles equipped with connected vehicle technologies while traversing Ann Arbor, Michigan. These sets of […]
