摘要: Vehicle speeds of roads are measured by the Intelligent Transportation Systems (ITS) through some sensors or software solutions. Our previous work proposed the Lin-Chang-Huangfu (LCH) scheme to compute the cell residence times by the standard counter values in the mobile telecommunications switches without any modification to the telecommunications network. In this paper, we extend the LCH scheme and some filtering techniques to estimate the vehicle speeds, and validate our approach with the vehicle detector measurements at National Highway 3, Longtan Township, Taoyuan County, Taiwan. Our study indicates that the LCH scheme can provide accurate vehicle speeds.
