In the related researches of highway service level and travel time estimation, which have been mainly focused on how to spread out the Vehicle Detectors in order to detect the velocity of the vehicles. Spreading the Vehicle Detectors, which is difficult to execute, consists of the following procedures : road digging, VDs spreading, and road reconstruction. Moreover, the as mentioned procedures could damage the backtops. To apply the procedures in downtown area is even more laborious, due to the limited resource and controls from local authorities. As a consequence, the unsufficient density and numbers of VDs could not well serve the information collecting standards.
目前道路服务水准评估、旅行时间预估等相关研究,在行车速率推估上多以路面上布设之车辆侦测器所搜集之资讯为主,但VD之埋设需经路面挖掘、VD布设、重铺柏油等程序,布设不容易且损坏率偏高,亦普遍存在维护困难的问题;尽管已有诸多研究开始利用AVI、资料融合、RFID等技术,增进以VD为交通资讯搜集主要来源之研究成果,但仍多因资讯搜集成本较高,无法进行全面性应用。
