現今社會的人們對於交通系統這個名詞應該都不陌生，舉凡大眾捷 運、公車、鐵路火車、飛機等..這些交通工具，都各自成立獨立的系統 並加以運作。尤以汽、公、機車、自行車與行人所成立的龐大紅綠燈交 通系統更是大家不陌生的。但是 大眾通常對於目前國內的交通系統多是 報怨不斷。本系統主要撰寫CPLD晶片之研究動態調整交通系統號誌，並 提供三種切換模式，藉此可得知此時路口為尖峰、離峰或是一般車流量 狀態，應用於多元化的交通系統號誌。因此 本報告提出一個創新概念去 實現一個能判斷路口車流量的新式多功能整合晶片系統。 This paper presents a novel design of intelligent traffic system integrated circuit that is implemented and developed based on the ALTERA CPLD chips. It can be obtained by the pressure sensor data traffic crossroads of four sides set a criterion, that crossroads of all vehicles flow in order to determine the parties to the order of vehicles to divert, thus the status of the individual to change the number of seconds to wait by the four sides of the orientation traffic lights and lights (R, G, Y). This system can also judge total vehicles flow volume of the crossroads by the data of pressure sensor at this time and know about the traffic status, the peak, off-peak or the general traffic state. System itself has three different states (Busy, Idle, Normal), each state has its specific traffic signals changes in the number of seconds to wait with the lights, so you can save the energy of the overall traffic system operation. In additions, the traffic system of infrared transceiver can be applied in the occasional emergency, the more extensive application of the overall traffic system.
