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.

joule heating:焦耳发热
较大的感测电阻值可以带来较高的精确度,但却会消耗更多的功率(P=I2R),其中I为测量所得的电流,R则为感测电阻值,所测得的电流大小会依应用而有所不同,并不是设计上的参数,因此感测电阻值必须尽可能地维持在较低的水准,以便将焦耳发热(joule heating)降到最低.
