The data elements contained in this data environment were collected during the Prototype Operational Data Environment (P-ODE) formal data collection period. The Prototype Operational Data Environment (P-ODE) is a system that receives data from multiple sources in real-time, is capable of performing validation, integration, and sanitization checks, transforms the data into a consistent format, and makes the data available to applications as well as stores the data in ITS JPO data system. This data environment contains speed, volume, occupancy, travel time, and incident data collected along I-66 in Northern Virginia between May 2016 and August 2016. The ASN.1 data set contains data records in their original binary form, while Detector and Incident data sets each contain records that have been converted to text format.

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.
