Several third-party data providers offer traffic data for a variety of transportation purposes. Many agencies use third-party probe data for freeway operations and some agencies also use this data on arterials to assist in overall operations. For this effort, ENTERPRISE members were interested in understanding the uses and suitability of probe speed data on arterials to support deploying or expanding operational uses. The purpose of this research was to assist ENTERPRISE members in understanding the overall status and key uses of arterial probe speed data for operations (real-time or post analyses) from a select number of agencies. This project focused on vehicle probe speed data without the need for deploying and maintaining equipment in the right-of-way. It excludes probe speed data that requires additional roadside infrastructure (e.g. Bluetooth, non-intrusive detectors).
