Arterial Management Crowdsourcing Examples

The following table lists organizations’ use of crowdsourced data (by source) to enhance aspects of arterial management. Please share your organization’s arterial crowdsourcing example with any of the Federal Highway Administration (FHWA) Everyday Counts Round Six (EDC-6) Crowdsourcing for Advancing Operations Innovation coleads listed under Contact Us.

What (Application)	Who (Organization)	Data Source	Brief Description
Assess Signal Timing Changes	Louisville Metro	Waze®	Louisville Metro applied Microsoft® Power BI® to its archive of Waze data to rapidly assess signal timing changes. The agency noted that access to data analytics enables a more robust, lower cost, and quicker assessment compared with traditional manual assessment methods such as floating car studies.
Prioritize Corridors for Signal Retiming	City of Austin	INRIX®	With camera coverage of only 18 percent of intersections, Austin, TX, had difficulty gathering useful traffic data to support prioritization of corridors for signal retiming. By purchasing crowdsourced data from an outside source, the city was able to implement a data-driven, prioritized signal retiming strategy, rather than its previous strategy, which sequentially retimed corridors over a multiyear period. This approach has enabled the agency to efficiently allocate resources and increase regional throughput.
Monitor Arterial Performance for Signal Retiming	District of Columbia DOT	Waze	The agency incorporates crowdsourced data into a dashboard that monitors minute-by-minute arterial performance. Then, the reported data are used to make more effective decisions on proactive signal retiming than would be possible without such data.
Traffic Prediction and Infrastructure Planning	Five municipal counties in Lake Tahoe area in California and Nevada	AirSage®	Several agencies that manage roads in and around Lake Tahoe used anonymized cell phone data from AirSage to identify traffic patterns and congestion areas. This analysis was used for infrastructure planning and traffic management strategies that supported a more consistent flow of traffic.
