摘　　要：为描述连续交通流中的停车波现象,分析了停车波传播的运动学特性,基于运动学方程建立了停车波模型。研究表明,该模型与基本交通波模型推导的停车波模型一致。为验证该模型,设计了数据采集方案及参数标定方法。利用长春市的调查数据标定了模型,得到停车波波速理论值与实测值之间的相对误差为3.85%。结果表明,基于运动学方程的停车波模型可以描述连续交通流中的停车波现象,参数标定方法简单可行。To describe the phenomena of stop-wave in the continuous traffic flow, a stop-wave model was built based on kinematic equation by analyzing kinematic characteristics of stop-wave spread. The results show that the built model corresponds with the stop-wave model derived from the basic traffic wave model. In order to validate the model the scheme of data collection and the method of parameters calibration were designed. By using the survey data in Changchun city, the model was validated and the relative error between the theoretical and observed value of the stop-wave velocity is 3.85 %. The experiment results show that the stop-wave model based on kinematic equation can describe the stop-wave phenomena in the continuous traffic stream and the method of calibrating parameters is simple and feasible.
