Multi-Modal Intelligent Traffic Signal Systems Signal Plans for Roadside Equipment
datahub.transportation.gov | Last Updated 2024-05-20T17:57:20.000ZData were collected during the Multi-Modal Intelligent Transportation Signal Systems (MMITSS) study. MMITSS is a next-generation traffic signal system that seeks to provide a comprehensive traffic information framework to service all modes of transportation.The Signal Plans for Roadside Equipment (RSE) data contains the basics of a Signal Phase and Timing (SPAT) message. This data includes SPAT message and the timestamp of the SPAT message. The data also provides the signal phase and timing information for one or more movements at an intersection.

2014 ITS World Congress Connected Vehicle Test Bed Demonstration Intersection Situation Data
datahub.transportation.gov | Last Updated 2024-05-01T01:04:04.000ZDuring 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.Intersection Situation Data (ISD) data set communicates MAP and signal phase and timing (SPaT) information. MAP information communicates an intersection’s location (latitude and longitude), elevation, and geometric features such as approaches and lane configuration. SPaT data communicates the (current) state of the intersection’s signal indication(s). The data is composed of discrete Row Groups. A Row Group is a collection of (approximately 3-4) consecutive rows with common attribute.

Next Generation Simulation (NGSIM) Vehicle Trajectories and Supporting Data
datahub.transportation.gov | Last Updated 2024-05-20T18:02:47.000ZClick “Export” on the right to download the vehicle trajectory data. The associated metadata and additional data can be downloaded below under "Attachments". Researchers for the Next Generation Simulation (NGSIM) program collected detailed vehicle trajectory data on southbound US 101 and Lankershim Boulevard in Los Angeles, CA, eastbound I-80 in Emeryville, CA and Peachtree Street in Atlanta, Georgia. Data was collected through a network of synchronized digital video cameras. NGVIDEO, a customized software application developed for the NGSIM program, transcribed the vehicle trajectory data from the video. This vehicle trajectory data provided the precise location of each vehicle within the study area every one-tenth of a second, resulting in detailed lane positions and locations relative to other vehicles.

Long-Term Pavement Performance (LTPP) - Library
datahub.transportation.gov | Last Updated 2024-05-08T00:25:58.000ZLong-term Pavement performance, construction, traffic, and environmental data for more than 2500 pavement sections in the United States and Canada. More than a dozen experimental designs address specially constructed and existing asphalt and concrete pavements, and maintenance and rehabilitation strategies. Data collection has been on-going since 1990. About one third of the pavement sections are still under study. New warm-mix asphalt concrete pavement overlay sections are currently being recruited and constructed.
