| Summary | The vehicle detectors are the basic infrastructures for ITS development. In Taiwan, most of traditional vehicle detectors are foreign products. Thus, the implementation costs are very expensive, and the maintenance and related techniques are dominated by foreign agencies. Besides, 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 team have cooperated on the feasibility study on the vehicle detectors prototypes development in 2005. The team developed two kinds of vehicle detector prototypes, vision-based and microwave-based, and their performances were verified successfully. In 2006, we continue to improve detection technique and enhance the accuracy under different-condition field tests. As for the vision-based vehicle detector, the system can identify the vehicles in multiple lanes during day or night time successfully. As for the microwave-based vehicle detector, we developed the CMOS IC of vehicle detector (which is first developed in Taiwan) and the antennas and composed the embryo detection system. Its prototype performs very well under primary testing. We hope the outcomes of the study could drive and corporate with the domestic manufacturers to produce the low-cost and high-accuracy vehicle detectors through technology transfer in the future. Furthermore, the vehicle detectors could be implemented more comprehensive and provide more complete traffic information. |
