The evaluation of route guide sign system and detection of stray crossing points in a network

Abstract

The route guide sign system is one of the route induction system in the road traffic. However, there are partially miss-match notation in the network because it includes contradiction in each notation addresses. Under these background, we are going to study on the method of notation addresses decision for the route guide sign boards, and will evaluate its network. In this paper, we describe the methods of evaluation for the route guide sign system and detection of stray crossing points in a network, using the induction route by drive-simulation. In the method of evaluation, we use the standard induction routes. The standard induction routes are imaginative one by route guide sign system. By comparing the standard route's distance with the result of drive simulation's one, evaluation values are calculated and stray crossing points are detected. By using this method, the route guide sign systems are evaluated in quantity, and the wrong route guide sign boards are likely detected. Finally, we show an application example of this evaluation method and detection of the stray crossing points for the route guide sign systems at the Northwest CHIBA area. © 1995, The Institute of Electrical Engineers of Japan.
