Practices on Acquiring Proprietary Data for Transportation Applications

Summary Information

The Kentucky Transportation Cabinet (KYTC) uses real-time speed data and traffic information derived from Waze crowdsourced data services as a decision support tool to monitor traffic congestion, gauge the effectiveness of snow and ice removal operations during severe weather, and to measure the impact of posted traveler information on both roadside dynamic message signs (DMS) and on a state-run traveler information website.

Leveraging its advanced IT infrastructure, KYTC now combines various data sources to characterize real-time roadway conditions throughout the state and posted them on a state-run website. Key data sources include:

  • HERE real-time speed data
  • Waze incident and jam reports
  • Waze traffic viewer
  • Twitter
  • Doppler radar
  • KYTC's traffic operations center
  • TRIMARC incident reports, snow plows, internal crowdsourced activities throughout the state, and DMS.

KYTC aggregates data from these sources and harmonizes them based on location and time. Information on alerts and delays from the real-time data are used to populate a real-time traffic information map on the state’s website (www.GoKy.ky.gov).

FINDINGS

In 2016, KYTC phased out its telephone-based 511 system and shifted all data management to in-house staff, saving the agency $750,000 per year.
