초록

본 논문에서는 네트워크 토폴로지 설계방법들(minimum spanning tree와 Dijkstra algorithm)을 사용하여 교통 격자 가로망을 최적화 하는 방안을 다루며, 최소신장트리(minimum spanning tree)에서 직진 교통신호등간의 연동들을 통해 출발지와 목적지간의 지연시간을 최소화 하는 것으로 교통격자 가로망을 최적화한다. 또한 컴퓨터 네트워크에서 사용되어지는 Dijkstra algorithm을 통해 구해진 경로에 따라 차량 운전자들이 그 경로를 준수한다고 가정한다면 격자망에서 교통신호등의 연동을 통해 최적화할 수 있음을 보여준다. 격자 가로망에서의 모의실험결과는 직진 교통신호등의 연동을 통해 망을 가로지는 지연시간을 최소화함을 보여준다.

In this paper, we deals with optimizing traffic signal timing in grid networks by using a network topology design method. Optimizing traffic signal timing includes minimizing delay time delay between departure and destination by interlocking straight traffic signal in the minimum spanning tree(MST). On the assumption that users of network abide by the paths provided in this paper, this paper shows optimizing traffic signal timing in grid networks. the paths provided in this paper is gathered by using Dijkstra algorithm used in computer networks. The results indicate minimizing delay time of passing through the grid network and interlocking traffic signal in the grid network.
