Vehicle speed is a critical metric for safety planning, roadway performance evaluation, congestion monitoring, and more. But, it is expensive and time-consuming to collect speed data with sufficient time and location coverage.
StreetLight provides on-demand vehicle segment and spot speed metrics that enable a multitude of applications, from visualizing average speeds across a network to evaluating free-flow speed trends on a particular roadway.
