Research And Evaluation On Driving Behavior In Curved Road For Unmanned Vehicles

Curve is a part of the highway. Compared to the linear section, the linear design includes the circular curve and the ease curve. Traffic accidents occur frequently, and the serious degree is high. When encountering static obstacles, unmanned vehicles in curved road prone to the risk of collision with obstacles. Study on intelligent behavior of unmanned vehicles under the condition of the curve is helpful to improve the safety of the vehicles in curved road.Applying the intelligent vehicle is an effective way to improve traffic situation. The data showed that accidents which were caused by human factors accounted for 92% and the driver factor reached 88.29%.Therefore, intelligent vehicle can be applied in the "human-vehicle- road(Environment)" system to improve the traffic efficiency and keep safe. At the same time, a variety of intelligent vehicles were developed by many domestic and foreign research institutions and universities.Test is divided into two kinds. One Scene is with obstacles and the other is without obstacles. The simulation platform Curve environment was established to collect the manned driving behavior by simulation software Creator and Vega Prime. The sensors were installed in the platform to collect the manned driving parameters. The manned driving behavior was summarized through the analysis of various parameters.A model of intelligent behavior evaluation index system and evaluation model were established based on grey correlation theory and improved analytic hierarchy process,Therefore standards and rules for the competition of unmanned vehicles in curved environment was formulated. At last, got the evaluation result and verified the feasibility of the model with the final results of "China Future Challenge".
