Esri, Waze partner on crowdsourced traffic data

DOT taps into Waze, GPS data

The Department of Transportation announced plans for two pilot programs that will integrate its existing datasets with near-real-time data sources to improve highway safety.

The first will integrate existing data on known crashes and highway design with speed-related data culled from anonymous GPS-enabled devices to see how the speed and roadway characteristics determine crashes. 

The second pilot project will integrate crash data from Waze, the app that crowdsources information on roadway conditions, with DOT's existing data to see if Waze can help estimate crash risk.

Waze data has been integrated into a number of state and local traffic applications.

The Google-owned service has been used by to tackle gridlock and double parking in Boston. Last year, Atlanta worked with Esri and Waze on CommuteATL, an online platform designed to help drivers plan their travel during the I-85 bridge reconstruction.  The California Department of Transportation, meanwhile, won a 2017 GCN dig IT award for its Caltrans QuickMap that integrated data from California Highway Patrol, the state’s traffic-monitoring centers, Google and Waze to keep drives up to date with road conditions.

Many cities use GPS to monitor the location of buses, police cruisers and trains.

With new data analysis pilots that augment traditional data sources with more timely information, DOT said it can create new multi-dimensional models of the U.S. transportation system.
