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. This is the primary loop detector data table. It contains one-minute volume, occupancy, and data quality flags for the arterial loop detector data.

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 data set was acquired by the USDOT Data Capture and Management program.

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.

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.

The Highway Performance Monitoring System (HPMS) 2020 dataset was compiled February 28, 2022 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This file geodatabase download provides HPMS data for each state as an individual feature class. This dataset represents the highway system as of the 2020 calendar year. HPMS provides data that reflects the extent, use, condition, and performance of the public roads in the United States. It consists of the All Road Network of Linear Referenced Data (ARNOLD) geometry and the Section Data which is the attribution. ARNOLD and Sections are linked though linear referencing and are part of the HPMS data program. These data are analytical for the purpose of supporting transportation programs, funding and policy decisions at a national level. Operational applications such as navigation and routing may take advantage of HPMS with the understanding that it represents the average and not “real-time” of the system. The Highway Performance Monitoring System Field Manual contains a detailed description of each data element including coding instructions and attribute definitions. The Field Manual is available at: https://doi.org/10.21949/1519108. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1519108

Data 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 GPS data set catalogs the vehicle operation data of the test vehicles that used for the MMITSS field testing. The data contains the performance and operation details of vehicles. This file contains a number of fields detailing elements such as vehicle position and speed, fidelity measures of GPS-based data elements, and vehicle operation data. NOTE: All extra attachments are located in Multi-Modal Intelligent Traffic Signal Systems Basic Safety Message

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.

The data in this repository were collected from the San Diego, California testbed, namely, I-15 from the interchange with SR-78 in the north to the interchange with SR-163 in the south, along the mainline and at the entrance ramps. This file contains information on the field observation and simulation results for speed profile from the Dallas, Texas testbed. The time reported for the speed profiles are between 2:00PM to 8:00PM in increments of 10 minutes.
