## MODELING BASIC OVERTAKING PROCESS ON A HIGH-WAY WITH THE DEFLECTION CURVE OF A BEAM WITH FIXED ENDS

• 摘要: 高速公路上两车间超车过程是最为基本的一种超车过程，传统模型不够简洁. 为 此，提出用固支梁挠度曲线表示较快车辆的速度-时间关系曲线，由此得到了一种 无格子模型. 与传统方法作了比较，得到了有用的结论. 此模型被用于实际的车辆行驶时间的计算中，计算结果与实际基本相符.

Abstract: Overtaking between two vehicles on a highway is one themost basic processes. Traditional modeling is notsimple enough. In this paper, the deflection curve of abeam of fixed ends is used to represent the speed-time relation of thefaster vehicle. In this way, a mesh-less model is found. Comparedwith a traditional model, useful results can be obtained. The beammodel is applied in a realistic case and the calculated results agree withobservation.
