This data set was acquired by the USDOT Data Capture and Management program. The purpose of the data set is to provide multi-modal data and contextual information (weather and incidents) that can be used to research and develop applications. Contains one full year (January – December 2010) of raw 30-second data for over 3,000 traffic detectors deployed along 1,250 lane miles of monitored roadway in San Diego. Cleaned and geographically referenced data for over 1,500 incidents and lane closures for the two sections of I-5 that experienced the greatest number of incidents during 2010. Complete trip (origin-to-destination) GPS “breadcrumbs” collected by ALK Techonologies, containing latitude/longitude, vehicle heading and speed data, and time for individual in-vehicles devices updated at 3-second intervals for over 10,000 trips taken during 2010. A digital map shape file containing ALK’s street-level network data for the San Diego Metropolitan area. And San Diego Weather data for 2010.
