Research On Impact Of Travelers' Route Choice Behavior Under Traffic Accident Information

In recent years,with the gradual deepening of urbanization in China,the rapid economic development,urban motor vehicle ownership increased rapidly.With the rapid growth of motor vehicle ownership,urban traffic problems will become increasingly prominent,of which traffic congestion is one of the main factors causing road traffic congestion.In order to mitigate the problem of urban traffic congestion caused by traffic accidents,it provides real-time traffic accident information to travelers through the advanced traveler information system(ATIS),thus helping to divert the impact of the accident section from both time and space Travel demand.This paper aims to study the behavior of traveler's route selection under the condition of traffic accident information.First of all,based on the domestic and international research results,this paper analyzed the traffic characteristics of traffic accidents and the factors influencing the selection of personal factors and traffic accident information.Secondly,the questionnaire of traffic willingness was designed according to the factors influencing the choice of travelers' path,and the data of the survey were analyzed.According to the research contents of this paper,constructs the characteristics of the traffic accident for the change.In addition,the paper also analyzes the characteristics of the most frequent travel time in the dynamic characteristics of traffic accident information,and constructs the traffic accident with the delay time as the parameter path behavior selection model under information condition.The model was calibrated and tested according to the survey data and the factors influencing the traffic accident information influencing the traveler 's travel behavior were analyzed according to the calibration result.The analysis results show that the important factors that affect the choice of traveler's travel path include the character,the familiarity of the road network,the purpose of the trip,the timing of the traffic accident,the degree of attention to the traffic accident information,the richness of the traffic accident information content,the increased delay time The results of the study have some practical significance for the traffic management strategy and the information release strategy of the traffic accident information system during the traffic accident.
