基于Agent的高速公路入口匝道信号交叉口优化仿真模型
An Agent-Based Simulation Model for Optimization of the Signalized Intersection Connected to Freeway On-Ramp
摘要：
与现有的出口匝道交通信号控制研究不同，本文主要研究与入口匝道相连的信号交叉口的优化问题。在通往入口匝道的交通和继续直行的交通之间经常观察到冲突，这导致诸如交叉口溢出、增加的延迟和安全问题。为了研究这个问题，选择了一个现实世界中的信号交叉口在布法罗，纽约，其中有两个直行车道和一个短的共享（直行和右转）车道。在交叉口的下游有两个匝道，一个通往I-290西高速公路，另一个通往I-290东高速公路。在高峰时段，共用车道经常观察到很长的队列，这进一步阻碍了平行车道上的直通交通。为解决这一问题，建立了基于VISSIM智能体的仿真模型，并根据现场观测数据对模型进行了标定。提出了3种可能的优化方案，并利用VISSIM软件进行了验证：（1）增加直行右转短车道的长度;（2）使直行右转短车道仅用于右转;（3）增加右转车辆的分流车道。根据仿真结果，解决方案（3）的性能最好，导致最少的车辆延误时间。
英文摘要：
Unlike most existing studies on off-ramp traffic signal control, this paper focuses on the optimization problem of the signalized intersection connected to freeway on-ramps. Conflicts are often observed between the traffic heading to an on-ramp and the traffic continuing straight which leads to issues such as intersection overflow, increased delay, and concerns about safety. For studying this problem, a real-world signalized intersection in Buffalo, New York was chosen, which has two through lanes and one short shared (through and right-turn) lane. At the downstream of the intersection are two following on-ramps, one to the highway I-290 West and the other to I-290 East. During peak hours, the shared lane often observes a long queue, which furthermore blocks the through traffic on the parallel lane. To solve this problem, a VISSIM agent-based simulation model was built and calibrated based on field observations. Three potential optimization solutions were proposed and tested with the help of VISSIM: (1) increasing the length of the short shared through and right-turn lane; (2) making the short shared through and right-turn lane right-turn only, and (3) adding a new diverge lane for the right-turn vehicles. According to the simulation results, solution (3) performs the best, resulting in the least vehicle delay time.
