Model-based Sensitivity Analysis of Transportation Risk Decisions on Over-Speeding iolation ehavior on Roads

摘要

Over-speeding constitutes a major concern for road transportation safety because of the resultant injuries and fatalities. The previous studies on over-speeding management give more attention to risk benefit analysis of single participant or single prevention method, lacking of the analysis on the influence to the behavior decision made by others participants from the road transport system. Considering the cost and benefit of over-speeding prevention, the behavior model of decision makers in the process of road transport is built, which is used to analyze the relationship between the factors related to traffic safety, such as the satisfaction degree of traffic safety etc. The projection algorithm is designed to solve variational inequality model of road transport system, and sensitivity analysis is used to reveal decision equilibrium point of transport safety. The results show that the combined utilization of multiple measures has great influence on traffic safety.
