最优化路网可观可控性的DSRC 网设计模型研究

我国高速公路电子不停车收费系统联网建设即将实现全国联网，如此大规模的系统互联为高速公路的运行管理带来了新的契机.既提供了一种可靠的交通运行状态信息获取方式，也构建了一个具有相当覆盖范围的车路交互平台，从而实现路网的协同管控与出行服务水平的提升.基于此，首先给出路网可观性、可控性的概念模型；其次根据 DSRC设备双向交互的特点，提出面向路网可观性与可控性双目标优化模型，基于路网旅行时间测量误差最小化为目标的路网可观性评估模型及基于路网系统旅行时间最小化为目标的路网可控制性评估模型，最后，通过数值算例对模型进行了验证.结果表明，提出的模型是可行的、有效的.

DSRC Network Design for Improving Observability and Controllability

Recently, the freeway electronic toll collection system will achieve national wide connected. This large- scale connected system brings several new challenges and opportunities to the freeway traffic operation and management. It can provide both a reliable way to obtain the freeway traffic states and a vehicle-infrastructure interactive platform with considerable converge, which can achieve cooperative traffic management and control and traffic service level improving. In this paper, the concept models of network observability and controllability are proposed firstly. According to the two-way interaction feature of DSRC equipment, a multi- objective optimization model is proposed, minimize the measurement error based on network observability model and minimize travel time based on network controllability model. In the end, the feasibility and validity of the model is verified through the numerical example.
