Analysis of Road Potential and Bottlenecks Based on Percentile Speed
Vehicle detectors have been installed at approximately every 300 meters on each lane on Tokyo metropolitan expressway. Various traffic data such as traffic volume, average speed, and time occupancy are collected by vehicle detectors. Traffic characteristics of every point can be understood by comparing traffic data collected at many points. In this study, the authors focused on average speed, analyzed road potential, and identified existing bottlenecks and latent bottlenecks. Furthermore, effects of congestion measures were examined by comparing percentile speed contours of each year. It is expected that this method of analysis will be utilized for installation of intelligent transportation systems such as drive assist, for estimation of parameters of traffic simulators and for feedback to road design as congestion measures.
