虛擬交控中心建置與應用

Construction and Application of Virtual Traffic Control Center

在交通問題日益繁雜的情況下,交控策略往往為改善交通問題的重要手段,而策略的擬定必須透過廣泛且正確的各項資料作為基礎,虛擬交控中心(virtual traffic control center,VTC)的建置便占重要的角色。一方面為實際交管中心(traffic management center,TMC)資料做備份,一方面可將資料提供與學術單位進行交控策略的擬定,並且亦可透過與實際交管中心相同使用者介面進行教育訓練,進一步培養交控人才。文中完成虛擬交控中心的系統建置,並開發交控策略績效平台,將虛擬交控中心模擬軟體所得到之時制計畫及其績效,透過資料庫同步方式將交控策略回饋台中市政府交管中心。虛擬交控中心未來將持續蒐集車流資訊,開發軟體,期望達到改善都市交通問題之目標。

The problems about traffic and transportation are getting more complicated. The traffic strategy is almost the best tool for the traffic managers to solve the situations of traffic congestions. However, enough data are needed to make traffic strategies. Thus, the construction of a virtual traffic control center （VTC） that gets data from various kinds of sensor devices is very important. In this case, the system of VTC, which is constructed in Feng Chia University, almost hackups data immediately from the traffic management center （TMC） of Taichung traffic department by its server. The software installation of VTC is the same as that of TMC. Therefore, the data can be used by research groups and by students on the same interface. In addition, a user interface is developed, which can show the traffic signal timing plan and its performance from the results of simulation software to feedback information of timing to TMC. In the future, VTC will integrate functions of software with traffic control system, and solve traffic problems.
