Road Traffic Signs And Markings Warning Capacity

The traffic sign marking offers the information of traffic systems of relevant roads to the road traffic participant, touch for vast road user widely most among road traffic technology, it is direction and guide that the driver drives a vehicle. Clear sign and marking can improve driver's traffic psychological pressure , get up and get dredge traffic flow, offer road information, lead direction gone, enforce the law basis and warn driver ahead danger, forbid the function of some traffic behaviors. At the same time , for safe and high speedy driving in road , the driver also depends on the apparently demarcated outline t of the road line and clear sign , under the guide of sign marking , set ups ahead the reference system of the direction, and establishes confidence towards the farther road that can be seen by him .Practice has proved , rationally and correctly building the traffic sign marking can use effectively the area of the road , adjusts the traffic , improve the traffic capacity of the road , reduces the traffic accidents, prevents the traffic jam, saves the energies , reduce the public hazards , beautifies roadsTraffic sign and marking warn , hint ability is a problem that is urge to be solved , settling the problem will offer road users good road conditions and service, which is part of researching road accidents in frequently highway section , studying safely driving vehicles , researching safe main road and smooth traffic project , road traffic sign uses graphical symbol, characters, to transmit drive person and pedestrian legal message , so as to control and guide the traffic, and play a very important role to traffic safety of the road. This paper at first expound the fact concept , the key influence element of Traffic sign' s warning ability Such as the condition of the road , people' s traffic behavior characteristic , the question , regulation and environment of the car , etc., study the traffic sign at present and set up the current situation on the foundation of collecting, arraying data, of domestic and international research results,. Secondly The paper analyze, calculate the traffic sign of the road traffic correctly through the theoryon the basis of summarizing the general design of the sign , setting up —Only allow the position and repetition of establishment of the speed sign to set up such questions as the interval , etc. while marking, design the rational experiment scheme, through proving the feasibility of the experiment, carry on the traffic sign in the road traffic that the traffic engineering institute of the institute of technology researches and develops independently of Kunming drives the simulator —Limit indicate set up experiment rapidly, and questionnaire investigation of experimenter count data analysis prohibition indicate speed limit of mark the repeated feasibility set up after testing through experimental data, probe into and improve the method and measure of warning ability of the marking of indicating.
