摘要：

Electronic toll collection system is popular applied to the payment collection of freeway all over the world. We derive the relationship of the coverage length of toll collection area m, the vehicle velocity nu,and the mean vehicle residence time 1/eta In addition, the processing time of client system is bounded by the factors of the mean vehicle dwell time, the propagation delay, and the transmission time. The upper bound of sewer response time is calculated from the mean response time of client system, the propagation delay, the transmission time, and the mean vehicle dwell time. Furthermore, the statistical probability bound for the response time performance of sewer has been defined by specified a response time for client system and the acceptable significance level of loss of service p in advanced. Finally, the M/M/z queueing simulation estimates the number of sewer z required for the stringent performance requirement.
