雷達微波偵測器交通參數校估演算法

Abstract

近年來政府大力推動旅行者資訊系統（ATIS），雖然目前已有許多便民即時的系統架設完成，但除國道、台北市重要道路以及部份零星地區可茲參考外，其他都市及郊區資訊嚴重不足，使得推動ATIS過程舉步維艱。 應用儀器進行大範圍且長時間的交通資料蒐集，是目前最適當的解決方法，由於偵測器應用數量相當龐大，因此鋪設與維護成本為重要選擇指標。具有可架設於路側，同時進行多車道偵測之雷達微波偵測器，是為一個相當適合的解決方案；本研究依據台灣第一部自行開發之雷達微波交通偵測器架構，開發專屬於此偵測器特有的交通參數演算法，使得本偵測器具有偵測各車道交通參數資料之功能，如車輛數、佔有率、車速、車種。 期望經由微波交通偵測器軟硬體規格的確立，引起國內更多學術研究或實務應用，形成台灣自有的技術產業。

Recently there are many convenient traffic facilities because the ATIS is impelled by the government in Taiwan. However, the traffic information is destitute except for the highway system and arteries in Taipei, so that the policy dispenses difficultly. It is the applicable way to amassing the traffic information passim and persistently by detecting instruments. The microwave radar vehicle detector provides installing on the side back and detecting of multi lanes. This research develops the calibration for the first detector manufacturing in Taiwan. It provides the function of computing Traffic parameters to the detector. This study believes that though the incitant of the hardware and software of radar-vehicle-detector establishing, and it could promote the research and application at this phase and become the proper tech instrument in Taiwan.
