Exploring Crowdsourced Monitoring Data for Safety

This project encompasses four different activities to explore safety applications of emerging crowd-sourced data and datasets available from commercial aggregators. The first activity examines systems used to monitor and count pedestrian activity. Developing crash rates for these vulnerable users depends on knowing the volume of activity. Data from metropolitan planning organizations as well as commercial and community-based reports of bicycle and pedestrian activity will be assessed for accuracy by comparing them to manual counts. The second activity will examine waypoint travel pattern data from a commercial data aggregator to determine its applicability to safety analyses. The evaluation will assess the geographic and temporal distribution and representativeness of the sample as well as how roadways of different functional classes are represented. The third activity will examine data from a crowd-sourced traveler information app to determine if incident reports in the app correspond to official incident records. The task will develop a data catalogue identifying data attributes, coverage areas, resolution of the data, and timeliness of the data. Overall these three exploratory efforts will provide future research projects an understanding of what is available from these new big data sources and how they could be used to improve safety.
