Probe Data
Public agencies charged with managing traffic flow, responding to incidents, carrying out planning activities, and maintaining the roadway have traditionally collected traffic data. FDOT uses inductive loop detectors, closed-circuit television cameras, and other surveillance devices to monitor conditions on roads. The recent advances in wireless communications and sensor technologies have resulted in increased private sector interest to develop innovative traffic data collection solutions. These innovations allow public sector agencies to more cost-effectively supplement and, in some cases, replace traditional traffic data collection infrastructure.
FDOT explored these technologies to provide validation testing of data quality attributes (e.g., accuracy, reliability, and timeliness) and travel time/speed data provided by two data content providers. FDOT explored two technologies- cell phones as probes and global positioning system-based probes – as primary data sources. The resulting documentation is as follows:
- Technical Memorandum: Evaluation of AirSage Travel Time System Data in the Tallahassee Region (Final Version 2 - August 20, 2010)
- Probe Data Collection Concept Test Overview (Final Version 2 - September 12, 2007)
- White Paper - Cell Phone Location System (Final Version 2 - August 2, 2007)
