Experimental Research On The Car Driver’s Spatial Perception

With the increase of the number of car ownership and car drivers,traffic accidents,most of which are related to the people,has always been high number.A lot of statistical data and accident analysis results show that the driver’s perception error is one of the main factors that lead to traffic accidents.Therefore,deeply understanding the driver’s perception,especially for the space perception and time perception,is of great significance for the road traffic safety,which can effectively decrease the traffic accidents caused by perception errors,improve the driver’s driving decision-making,and make the design of traffic facilities better.Firstly,the research status at home and abroad is systematically analyzed.The origin and development of experimental psychology,cognitive psychology and traffic psychology are introduced,emphasizing on the research process of the basic perception,the driver’s perception and the blindfolded walking paradigm.On board experiment on real urban road based on the blindfolded walking method is determined.Secondly,the car drivers’ perceptions and their characteristics are expounded,from the perspective of physiology and psychology.Kinds of perceptions’ mechanism and characteristics,such as vision,auditory sense,tactile sense,space perception,time perception and so on,are systematically introduced.The impact of various factors on perceptions,such as external environment,individual differences,age,experience,emotion and so on,is briefly illustrated.It lays a solid theoretical basis for on board experiment and data analysis.Thirdly,basing on the blindfolded walking method,the experiment is reasonably design and well done.It shows the experimental purpose,experimental participants,experimental equipments and experimental scene,elaborates the experimental schedule and considerations,and introduces the method of recording experimental data.The data of time-to-collision under the influence of different factors are obtained through the experiment.Lastly,the space perception characteristics under the influence of the different factors are obtained through processing and analysing on the data of head-on perceived distance,converted from the data of time-to-collision.With the aid of SPSS,using a variety of methods of mathematical statistics,such as normality test,paired sample test,repeated measurements analysis of variance and outline chart analysis,to process the data of head-on perceived distance,the law of space perception influenced by different factors is got.Viewing from car drivers’ space perception,the research obtains the car drivers’ time-to-collision data,through on board experiment under different conditions,takes mathematical calculation and statistical analysis,and studies the influence of various factors on experimental results.It has a positive meaning for deeply understanding car drivers’ space perception,reducing traffic accidents caused by car drivers’ perception errors,improving car drivers’ screening mechanism,etc..
