Outline
In order to reduce conflicts between heterogeneous traffic flows during overtaking，a non-motorized lane width design method that considers avoidance maneuver in heterogeneous traffic was proposed. This method represents an improvement over the traditional design approach. Firstly，the conflict levels of non-motorized vehicles were analyzed through the deceleration group proportions and pedaling cadence. Secondly，a vehicle-to-vehicle force model was established to calculate the forces between different types of vehicles. The additional safety gap was determined based on the relationship between these forces and lateral width. The recommended non-motorized lane width was the sum of the traditional lane width and the additional safety gap. Then，the rationality of the proposed design method was evaluated based on the safety levels of non-motorized lanes with different widths，which was obtained from the safety evaluation model developed in this research. Finally，data from four non-motorized lanes in Xi'an city were analyzed as case studies. The research results show that the deceleration group proportion is 0.93 times，pedaling cadence increases by 0.07 revolutions per second，and the road safety value is 1.07 times compared to traditional non-motorized lanes in non-motorized lanes accommodating heterogeneous traffic. These findings demonstrate that lanes meeting the design width have lower conflicts and greater safety.
