Summary Vehicle detectors are basic infrastructures for ITS development. In Taiwan, most traditional vehicle detectors are foreign products. Thus, implementation costs are very expensive, and maintenance and related techniques are dominated by foreign agencies. In addition, these detectors cannot perform very well under the sophisticated traffic environment in Taiwan, such as mixed traffic flow. In order to expand the sources of traffic information, IOT and NCTU teams have cooperated on the feasibility study of vehicle detector prototype development, in 2005. The team developed two kinds of vehicle detector prototypes, vision-based and microwave-based
their performances were successfully verified. In 2006 and 2007, we continue
to improve detection technique and enhance accuracy under different-condition field tests.
  For the vision-based vehicle detector, the system can successfully identify vehicles in multiple lanes during day or night. The system was also integrated with CCTV feasibly. As for the microwave-based vehicle detector, we developed the CMOS IC vehicle detector (which is first developed in Taiwan) and the antennas and composed the embryo detection system. The prototype performed very well under primary testing. In 2007, we improved the hardware of the microwave-based vehicle detector and its identifying software with self-designed user interface.

  We hope the outcomes of the study could drive and cooperate with the domestic manufacturers to produce low-cost and high-accuracy vehicle detectors through technology
transfer in the future. Furthermore, vehicle detectors could be implemented more comprehensively and provide more complete traffic information.
