Study On The Influence Of Speed Limit Signs Upon Drivers' Behavior

With the rapid development of economy and society, the transportationinfrastructure bottleneck restriction function has been more and more obvious. Thiskind of restriction mainly manifests in is impeded as a result of the transportationbut creates the traffic safety hidden danger. The system of the urban roads took theskeleton on a city, is a more complex transportation large-scale system, thus themunicipal transportation security and the smooth question are more prominent. Atthe same time, the human factor is the road traffic accident principal factor, illegaldriving causes the mortality rate to reach as high as 70%-80%. Many reports calledthat "Overspeed" has been list as "the dangerous factor which the influence trafficaccident occur". The regulating symbolized took the urban road traffic control thefoundation safety equipment, is the most universal way of control vehicle speed, isplaying the vital role in the traffic control. At present, the design of the Speed limitssign, establishes much is based on the path linear, condition and so on apparentdistance, but very few people research that from driving psychology behavior.This article in view of this kind of situation, depends on the country naturalfund project "the driving behavior coordination simulation modeling theory and themethod research", in carries on the questionnaire survey and the simulationfoundation to the driver, first analyses the driver behavior and the setting gist of thespeed limit signs, and build up information process framework model aboutcognize psychology.This paper determined using the factor analytic method to certain the mainfactors which affect the drivers to distinguish the speed limit signs, in thisfoundation determined the driver behavior pattern about distinguish the speed limitsigns. Then we demarcated the speed model and examed it. And finally, this paperdraws a series of conclusions and suggestion. Now, we sum up the main content ofthe whole paper:Chapter one is exordium. It mainly introduces the researching background,research situation, target, meaning, content and the technique route of thisdissertation.In chapter two, this dissertation analyses the driver′s cognize behavior in theprocess of traffic information and build up a framework model of the informationprocess. Then this dissertation analyses the speed limits signs′ setup based theframework model and analyses the influence factors of the setting.In chapter three, based on the analyses of driver behavior ,it analyses andsums up the key driving behavior shaping factors using Factor analysis method bySPSS. Combining with the analysis to the drivers′ behavior of using speed limitsigns, this dissertation use for reference the achieved study accomplishment aboutthe speed behavior at the speed limit signs and certain the parameters of the model.In chapter four, it chooses a parameter which called drivers′ obedience in forceas a measure of effort of the speed limit sign. And we fix on the parameters in themodel used the data of the questionnaire. Then it analyses the influence of thespeed limit signs based on the simulation software and questionnaire. At last, aseries of measures and opinions have been put forward.Chapter five is the summary. The main research content are summarized andthe problems which need to be researched more deeply are presented.Main achievement of this dissertation:1. It analyses the drivers′ information process referring to the modernviewpoint of Cognize and Psychology It builds a framework model basedon the analysis of the drivers′ information process.2. Based on the analyses of driver behavior, it analyses and sums up the keydriving behavior shaping factors using Factor analysis method by SPSS.3. Combining with the analysis to the drivers′ behavior of using speed limitsigns, this dissertation use for reference the achieved studyaccomplishment about the speed behavior at the speed limit signs andcertain the parameters of the model.4. It chooses a parameter which called drivers′ obedience in force as ameasure of effort of the speed limit sign. And we fix on the parameters inthe model used the data of the questionnaire. Then it analyses the influenceof the speed limit signs based on the simulation software and questionnaire.At last, a series of measures and opinions have been put forward.
