This report presents the results of the third and final research and development project of an implementable wireless travel time data collection system. Utilizing Bluetooth wireless technology as a platform, the prior projects focused on data collection hardware and network communication implementation. In this project the processing and synthesis of collected data was addressed. Results and procedures that address data filtering, travel time sample calculation, calculation of travel time statistics, travel time forecasting are described. Results for the use of collected data to estimate intersection performance are presented, as are the design and requirements for an automated travel time data collection system. The report includes a users’ manual.
