高速公路枢纽互通式立交出口指路标志设置研究

Abstract

System interchange is the most advanced node in the expressway network or the functional road network system with trunk, and is responsible for the important function of the conversion of traffic flow between the expressway network and the trunk highway network. With the continuous expansion of the city scale and the rapid construction of expressways throughout the country, the number of System interchanges has continuously increased. In order to reduce the proportion of accidents at the exit of the System interchange, the traffic safety and traffic efficiency of interchange are improved. Based on the analysis of relevant domestic and foreign researches. This paper points out the requirements and problems existing in the application of the signage system of China's guideline system in the System interchange, and selects from the layout information of the optimized guide sign. The layout of the layout, the setting position of the mark and the selection of support methods were studied. The classification method of hub interchange and the principle of selecting layout information were proposed; a new ramp control point was selected, and a driver’s drive was established based on a two-lane direct exit ramp. The out-of-the-road model is used to optimize the setting of the guide sign.

Finally, set up 6 sets of different exit warning signs optimization programs. Through UC-Win/Road modeling and driving simulator experiments, related data indicators of experimental vehicles were obtained, the differences of different setting schemes were studied, and the most Reasonable setup plan; research results show that the rationality of the status quo setup plan for China's hub interchange exit signage system needs to be improved. This paper gives a relatively good comparison of the status System interchange signposting signage system. Setting plans have certain reference value for the improvement of relevant technical standards in China.
