The objective of this study was to investigate the feasibility of using a Bluetooth Probe Detection System (BPDS) to estimate travel time in an urban area. Specifi cally, the study investigated the possibility of measuring overall congestion, the trend in congestion, the location of congestion “hotspots,” and the measurement of the level of congestion at the hotspots using a BPDS. A secondary objective was to assess the possibility of obtaining travel time from other quicker and cheaper methods such as simply purchasing it from a commercial vendor. |
