Contains all PDCMs generated during the AMCD field testing program. The PDCM is a control message sent from the server to OBUs to customize a request for Probe Vehicle Data (PVD) from the receiving OBU. All PDCMs are generated by the VCC Cloud server and transmitted to OBU clients through either a DSRC or cellular communications channel.

The data in this data environment was collected from the Pasadena, California testbed, namely I-210, SR 134, and nearby arterials. The source of these data is from the Caltrans – Performance Measurement System (PeMS). Speed data from this dataset were used to derive the freeway travel time. There are three separate text files with one for each operational condition.
Intelligent Network Flow Optimization Prototype Infrastructure Traffic Sensor System Data Aggregatordata.transportation.gov | Last Updated 2019-10-30T07:39:05.000Z
Data is from the small-scale demonstration of the Intelligent Network Flow Optimization (INFLO) Prototype System and applications in Seattle, Washington. Connected vehicle systems were deployed in 21 vehicles in a scripted driving scenario circuiting this I-5 corridor northbound and southbound during morning rush hour. This data set contains real-time volume, speed and loop occupancy data that were collected from WSDOT’s simulated roadway sensors every 20 seconds and aggregated according to user defined procedures and threshold by the Infrastructure Traffic Sensor System (TSS) Data Aggregator software.

During the 2014 ITS World Congress a demonstration of the connected vehicle infrastructure in the City of Detroit was conducted. The test site included approximately 14 intersections around Detroit’s COBO convention center and involved 9 equipped vehicles. Traveler Situation Data (TSD) was obtained from the data warehouse, and not the data clearinghouse. Only 19 messages were obtained from our query as the current mode of operation of the Test Bed is that the warehouse only contains a few static messages, which are meant to serve as a proxy for future operation in which query submissions will only return message(s) relevant to the context in which the query was submitted. The messages that returned per a query submission communicates a pertinent advisor message which is in part contextualized by location and content. NOTE: All Extra Files are attached in 2014 ITS World Congress Connected Vehicle Test Bed Demonstration Vehicle Situation Data
