Research On The Traffic Conflict Of Electric Bicycles And Vehicles On Urban Road Intersection

The characteristics of the electric bicycle due to its convenience,fast more and more liked by people.At the same time,due to the rapid growth of the number of electric bicycles on the road,the traffic safety and traffic efficiency of roads and intersections have been seriously affected.Especially in the grade crossing road,the traffic conflict between the electric bicycle and vehicle is very serious under the condition of mixed traffic,traffic accidents often occur.Therefore,it is of great practical significance to research the traffic conflicts between electric bicycles and vehicles.First of all,the paper researches the electric bicycle characteristics and using characteristics.According to the actual survey data,this paper analyzes the arrival distribution of the electric bicycle in five intersections of Guilin.It is concluded that the arrival and distribution of electric bicycles in the urban grade crossing roads are subject to negative two distribution,and the average density and the maximum density of the entrance lines are obtained.Secondly,researched the release law,and obtained the saturation flow rate and driving speed.According to the practical investigation,this paper researched the microscopic driving behavior of electric bicycle in the grade crossing road,analyzed the grade crossing road of the microscopic behavior of right turn vehicles crossing with straight line electric bicycle,according to the characteristics of mutual crossing between them,established through the selection probability model of a Logistic regression model,and then according to the intersections of Guilin city in the actual survey data,analyzed the significant influence between straight vehicle electric bicycle and right turn each other through the activities of decision factors in the intersection,appointed the calibration parameters of the Logistic regression model.Finally we verified the Logistic model.Focus on the analysis of the traffic conflict of electric bicycles and vehicles,researched the effects of electric bicycles on the traffic efficiency to vehicles,through the analysis of actual data,proposed the correction coefficient of right turn and straight vehicle line saturated flow.Finally,analyzed the release,reaching law and conflict of electric bicycle of signal intersection,and established the right turn vehicle collision probability calculation model,and calculated the probability of conflict of these two streams of traffic through the actual survey data of concrete intersection.
