Abstract
The random lane-changing behavior of electric bicycles brings a great safety hazard to urban transportation: According to the national traffic accident statistics in 2015, 8.22% of traffic accidents are caused by non-motor vehicle violations. Among them, the accident rate caused by electric bicycles is as high as 78%. In order to effectively analyze and quantify the risk of this lane-changing behavior, based on the non-cooperative strategy model under complete information, a Z-test of the speed before and after the “illegal” lane-changing behavior was carried out by using the data of the mixed-flow sections of Xi’an city. Constructing the judgment matrix to determine the weight value of motor vehicles’ game strategy and constructing the charge matrix, the utility income analysis of the electric bicycle and the affected motor vehicle is made by using the payment function, and the exceeding conflict model is established to quantify the risk level of the conflict number in the unit road. It is verified that the “illegal” lane-changing behavior of electric bicycles is a goal-oriented behavior for obtaining greater desired speed.
Highlights
As the main body of non-motor vehicles in urban areas, electric bicycles can provide “door to door” travel service for residents, but their “illegal” traffic behavior, such as speeding and driving randomness, bring a great safety hazard
It is of great practical significance to improve urban traffic safety management through studying the random lane-changing behavior of electric bicycles from bicycle lanes to motorlanes under mixed-traffic circumstances
In terms of traffic flow characteristics, there are many ways to analyze the impact of electric bicycles on motor vehicle flow as well as the design approaches of electric bicycle facilities under the circumstances of traffic congestion [1,2,3,4]
Summary
As the main body of non-motor vehicles in urban areas, electric bicycles can provide “door to door” travel service for residents, but their “illegal” traffic behavior, such as speeding and driving randomness, bring a great safety hazard. The lane changing of electric bicycles into motor vehicle lanes has the greatest impact on the nearest motor vehicle. The lane changing of electric bicycles into motor vehicle lanes has the greatest impacSutstoainnabtihlitey 2n0e18a,r1e0s, t motor vehicle. The two-person non-cooperative game i3souf 1s2ed to describe the lane-changing behavior of electric bicycles. It is found that the motivation of electric bicycles changing from the bicycle lane to the motorized lane is to obtain higher speed. In order to quantify the utility value brought by the “illegal” lane-changing behavior, a Game Charge Matrix was constructed
