- Abstract
- The primary purpose of this research is to develop a road collision warning information (RCWI) model using telematics devices on SMART roads. This paper focuses on the effect of real-time, environmental/incident-hazard information using telematics devices for in-vehicle unit advisory systems, and suggests a detection and estimation model using new IT technologies at signalized intersections for collision warning. Signalized intersections pose safety and operational challenges. For instance, dangerous situations may arise such as a failure to stop in time for, or blatantly running, a red light accelerating through a yellow light, or abruptly stopping in the middle of an intersection. This paper presents the development of a road collision warning model for vehicles travelling in phase change using real-time vehicle speed and the time between multiple point detectors. For an evaluation of this model, VISSIM was used to create multiple detection situations in real-time, various inflow-volumes, changes in the remaining times for a green light period, and road design speeds. In our results, about 0.8 - 2.3% of the entire traffic flow was classified as collision warning vehicles, while 35.8% was classified as collision warning vehicles during a yellow signal. This research considers that new service applications for increasing safety at signalized intersections are possible. The road collision warning information model may directly contribute to providing such safety for overall vehicle users on SMART roads.
