· Develop a Bluetooth MAC Address Detection (MACAD) system.
· Extract travel time data for a highway section by using Bluetooth MAC address matching.
· Evaluate the travel time data errors produced by the Bluetooth-based method by comparing travel time data extracted from Bluetooth MAC address matching and those resulting from ALPR.
· Conduct a thorough investigation of error sources of the Bluetooth-based method.
· Propose error control guidelines for Bluetooth-based travel-time data collection.

Bluetooth Media Access Control (MAC) address based travel time data collection is a new and dynamic research area. To ensure that this research project best serves WSDOT’s engineering needs, an advanced budget number was issued in May to start the research early. Mr. Yegor Malinovskiy and Mr. Yao-Jan Wu are currently working on this project. Dr. Un Kun Lee, a visiting professor from Korea, is also on the research team to help the project.

The research team has reviewed all the published materials on the Bluetooth MAC address-based travel time data collection research. We are currently improving the prototype Bluetooth-based travel time data collection system developed before the start of this project. An improved system has been designed and developed for preliminary travel time data collection and error analysis. The data collection sites selected are those locations on SR-522 with license plate recognition (LPR) systems installed. Travel time data collected from LPR and Bluetooth will be compared and solutions to reduce travel time data error in the Bluetooth system will be studied. Findings will be summarized in a paper to be submitted to the annual meeting of Transportation Research Board (TRB) for presentation.

This project is currently ahead of schedule.

In the coming six months, we will focus on the Bluetooth MAC address-based travel time data collection system design and implementation. Our target is to increase the detection rate and reduce travel time data errors.
