    • Abstract:
      The Ohio Department of Transportation (ODOT) currently employs a network of side fire speed radar devices to measure travel speeds and travel times on their interstate network. While these devices measure the instantaneous spot speed, segment level speeds may be more advantageous. Bluetooth devices are used in a data collection technique to support the measurement of travel times and speeds by comparing two or more time-stamped positional measurements. The purpose of this research is to develop a Bluetooth device capable of recording the media access control (MAC) addresses of target radios on Interstate 71 and calculating the resulting space mean speed. Based on the development of these Bluetooth devices, recommendations including node spacing configurations are developed for urban and rural settings along I-71.

      Objectives

      There are four objectives in this study:

      • Objective One – Develop a system that uses Bluetooth technology to capture and match signals from vehicle based Bluetooth devices.

      • Objective Two – Determine minimum required spacing of devices to produce accurate travel times.

      • Objective Three – Deploy sensors along a designated roadway and collect data in real time.

      • Objective Four – Summarize the final results."
