Therefore, in december 2000 the bureau of transportation of taipei city government completed a feasibility study for an lrt system in the taipei shin - yi district. this study recommended the adoption of an lrt system with a standard track gauge, power supply from overhead wires, two or three cars per train, a length of 90m for platforms, a certificate system for fare payment, consideration of the possibility of using electronic sensor ticketing systems, type b right - of - way for at grade sections, and signaling control for passing priority at the intersections. the study also proposed an initial lrt line of 9. 6 kilometers in length with 9 stations
現代化輕軌運輸系統之運輸效能已較電車系統大幅提升，以一般採用b型路權為主，少部分a與c型路權之系統而言，每小時單向運能達到5 ， 000至15 ， 000人次，介乎高運量捷運與公車系統之間，適合擔負都會地區市郊與市中心區的聯絡路線、市中心區集散路線、鐵路與捷運系統接駁路線、都市周邊環狀線、特定區間（新市鎮）聯絡線、都會區次要運輸走廊運輸主軸等服務類型。 -
In the control process uses two bp network. one is used as nni recognizing the model, another as neural network control device ( nnc ). but first off - line recognizes controlled device, make sure nnc initial weights
在控制的過程中，採用兩個bp網路，一個作為神經網路辨識器（ nni ）進行辨識建模;另一個作為神經網路控制器（ nnc ） 。 -
Following are detailed steps of this system : in the segmentation section, we use three successive frames to detect the motion infomation of the pictures, by using blockmatching algorithm in two successive frames twice, we can get two pictures composed of motion blocks of the moving object, then we find out the common motion blocks of the two pictures, experiments prove these blocks approximately compose the moving object. after getting the motion blocks, we calculate the center of these blocks as the center of the moving object, thus we can use the center point as the origin, construct n straight linesjoining the boundry of the image and the center. on each line, we can find out a proper point near the object contour according to some criteria, then we use these n points as the initial points of the snake and let the snake converge on the object contour, thus finish the segmentation of the moving object
本方案的實現過程為：分割部分：對運動目標的前後三幀進行兩次塊匹配運動檢測，通過找出兩個匹配結果中運動圖像塊的公共部分，獲得組成運動目標的圖像塊；求出運動目標圖像塊的形心作為運動目標的中心，以此中心為端點，向四周發散出角度間隔為的n條射線，射線的另一端終止於圖像的邊緣；在每條射線上按照一定的準則（點的梯度和與目標中心的距離在一定閾值范圍內）找出n個初始輪廓點；以這些初始輪廓點作為主動輪廓模型（ snake ）的初始點，用改進的貪婪演算法使snake收斂到待分割的運動目標輪廓上。
