Feasibility of traveling time estimation with mutual comparison of CVP, GVP and VD technologies

This paper proposes a feasibility study of traveling time estimation with mutual comparison of cellular-based vehicle probe (CVP), GPS-based Vehicle Probe and vehicle detection (VD) technologies. The travel time estimation algorithms have been designed for VD, CVP, GVP and some case in EVP (ETC-based Vehicle Probe). We have compared the system performance outputs at National Highway #1, Fast way #66, local governmental road #1 at Taoyuan to Jong-Li, and Sun-Moon Lake area on specific continuous holiday or working days. The outcome of this research is to target a CVP deployment with a percentage rate of 1%, a sample interval of 10 seconds and transmission interval of 30 seconds. Such a system will accurately determine the locations of both incidents and the tail end of traffic jams. It can be used to estimate travel times with mutual comparisons for VD, CVP, GVP, and EVP especially on continuous holidays. If we select the total # of NLU (number of location update) is less than 100 at local road section, then the CVP has good condition at traveling time estimation.
