Speed Spatial Distribution Models for Traffic Accident Section of Freeway Based on Computer Simulation

Speed Spatial Distribution Models for Traffic Accident Section of Freeway Based on Computer Simulation

Simulation models for accident section on freeway are built in microscopic traffic flow simulation environment. In these models involving 2-lane, 3-lane and 4-lane freeway, one detector is set every 10 m to measure section running speed. According to the simulation results, speed spatial distributio...

description Simulation models for accident section on freeway are built in microscopic traffic flow simulation environment. In these models involving 2-lane, 3-lane and 4-lane freeway, one detector is set every 10 m to measure section running speed. According to the simulation results, speed spatial distribution curves for traffic accident section on freeway are drawn which help to determine dangerous sections on upstream of accident section. Furthermore, the speed spatial distribution models are obtained for every speed distribution crate. The results provide theoretical basis for determination on temporal and spatial influence ranges of traffic accident and offer reference to formulation of speed limit scheme and other management measures.
