ROBUST PARAMETER ESTIMATING METHOD FOR CRASH HOTSPOT IDENTIFICATION BASED ON TRAFFIC ACCIDENT FREQUENCY SIMULATION

摘要

Disclosed is a robust parameter calculating method of a selection method of a vulnerable section for traffic accidents, which comprises the steps of: receiving actual accident data; inferring a simulation parameter on the basis of the actual accident data; generating one or more traffic accident simulation data by performing a traffic accident simulation using the simulation parameter, and defining a virtual vulnerable section for a traffic accident on the basis of the traffic accident simulation data; evaluating an error rate of whether the virtual vulnerable section for a traffic accident is selected by variously changing a parameter value of a selection method of a vulnerable section for traffic accidents; and calculating a robust parameter of the selection method of a vulnerable section for traffic accidents through an evaluation result.
