MITIGATION OF TRAFFIC CONGESTION, ACCIDENTS AND ENVIRONMENTAL IMPACT AT INTERSECTIONS BY ITS |
| บทคัดย่อ (อังกฤษ) |
Geometrical features of intersection such as, T and 4 Leg layout can give rise to several conflict points at intersection. The improper traffic controller can lead to traffic congestion and accidents. This paper describes one of the pioneering uses of ITS technology to mitigate traffic congestion, remedied road environment and traffic accidents at intersection. The intersections of the case study area are located in suburban Bangkok (Nonthaburi Province) where major accidents have occurred as a result of red-light running, and speeding. ITS technology, including image sensing concept for adaptive synchronization (Green Wave) was used to detect headway, spacing, number of speeding vehicles, angle of lane changing and number of vehicles changing lane. In addition, VMS was also used to flash warning message to errant drivers. After the implementation of this locally developed ITS technology, it was found that traffic flow was significantly improved and the number of accidents caused by red-light running and speeding decreased drastically. In addition, the adopted traffic environmental model were evaluated and the values somewhat fell from the previous situations.
