Arterial Performance Measures in a Connected Vehicle Environment

摘要: Wireless communication between vehicles and the transportation infrastructure will provide significantly more timely comprehensive information about arterials their performance. However, most measures-of-effectiveness were developed based on data available from traditional “point” sensors. The made in a connected vehicle environment requires new metrics that can fully utilize data. This paper identifies several arterial performance environment, as well existing be evaluated accurately frequently than before. are person-delay, sudden deceleration, change lateral acceleration, aggregate regulation compliance. Person-delay measures vehicle’s lost time multiplied by number of passengers, allows for efficient movement high-occupancy sophisticated transit signal priority. Sudden deceleration acceleration measure activities such unexpected braking swerving, which may leading indicators unsafe conditions. Aggregate compliance detects driving behavior is difficult to collect field, speeding illegal U-turns. Engineers address problem areas through timing changes traffic calming, other measures. proposed all require high-resolution detection, or impossible with point detection. For each metric, its compatibility discussed, required SAE J2735 DSRC Message Set Dictionary elements identified.
