This set of data files was acquired under USDOT FHWA cooperative agreement DTFH61-11-H-00025 as one of the four test data sets acquired by the USDOT Data Capture and Management program.The freeway data consists of two months of data (Sept 15 2011 through Nov 15 2011) from dual-loop detectors deployed in the main line and on-ramps of a Portland-area freeway. The section of I-205 NB covered by this test data set is 10.09 miles long and the section of I-205 SB covered by this test data set is 12.01 miles long The data includes: flow, occupancy, and speed.

The purpose of the data environment is to provide multi-modal data and contextual information (weather and incidents) that can be used to research and develop Intelligent Transportation System applications. This data set contains the following data for the two months of September and October 2011 in Pasadena, California: Highway network data, Demand data, Sample mobile sightings provided for a two-hour period, provided by AirSage (see note 1 below), Network performance data (measured and forecast), Work zone data, Weather data, and Changeable message sign data. This legacy dataset was created before data.transportation.gov and is only currently available via the attached file(s). Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

This set of data files is one of the four test data sets acquired by the USDOT Data Capture and Management program. It contains the following data for the six months from May 1 2011 to October 31 2011: -Raw and cleaned data for traffic detectors deployed by Washington Department of Transportation (WSDOT) along I-5 in Seattle. Data includes 20-second raw reports. -Incident response records from the WSDOT's Washington Incident Tracking System (WITS). -A record of all messages and travel times posted on WSDOT's Active Traffic -Management signs and conventional variable message signs on I-5. -Loop detector volume and occupancy data from arterials parallel to I-5, estimated travel times on arterials derived from Automatic License Plate Reader (ALPR) data, and arterial signal timing plans. -Scheduled and actual bus arrival times from King County Metro buses and Sound Transit buses. -Incidents on I-5 during the six month period -Seattle weather data for the six month period -A dataset of GPS breadcrumb data from commercial trucks described in the documentation is not available to the public because of data ownership and privacy issues. This legacy dataset was created before data.transportation.gov and is only currently available via the attached file(s). Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

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.

Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

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 for the USDOT Dynamic Mobility Applications (DMA) program. This legacy dataset was created before data.transportation.gov and is only currently available via the attached file(s). Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

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.

This data were collected during the Safety Pilot Model Deployment (SPMD). The data sets that these entities will provide include basic safety messages (BSM), vehicle trajectories, and various driver-vehicle interaction data, as well as contextual data that describes the circumstances under which the Model Deployment data was collected. Large portion of the data contained in this environment is obtained from on board vehicle devices and roadside units. This legacy dataset was created before data.transportation.gov and is only currently available via the attached file(s). Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

These data files were obtained from Minnesota Department of Transportation (MnDOT) under the Integrated Mobile Observation (IMO) contract. The instrumented vehicles include snowplows (made by Sterling and International) and light-duty pickups (made by Ford). The snowplows travel pre-determined routes in 12-hour shifts during winter-weather events, carrying out winter-maintenance activities appropriate for the event and MnDOT rules of practice (snow-plowing, applying chemicals, etc.). The light-duty vehicles travel throughout the state. Data from May 2013 onward is included. The files include VaiX records, DjX records, CanX records, ObdY records, vehicle location and status and store-and-forward messages.
