Abstract

Due to the fast developments of information technology and sensor technology, drivers get a precise estimate of real-time traffic conditions in the next moment. According to the situation, drivers can change their driving behavior while using their skills in advance with the help of prior information and they change their path through the turning point on road. To explore this phenomenon, a two-dimensional (2D) lattice model by incorporating the prior information (predictive effect) with the junction on road is proposed. At the junction of the road, traffic can enter into various downstream lanes from the upstream. The intensity of traffic at downstream may vary depending on the proportion of traffic. To analyze the proposed model, the stability condition is obtained without and with the control signal through the control method which shows that the stable region increases when the control signal is considered into account. The theoretical findings indicate that the predictive effect could affect the stability of diverging traffic. Numerical simulation verifies the theoretical findings which shows the results for the traffic flow stability with the consideration of the predictive effect and junction on road in 2D lattice model.

影响二维 (2D) 网络中交通动态的先验信息

摘要

由于信息技术和传感器技术的快速发展，驾驶员可以在下一瞬间准确估计实时交通状况。驾驶员可以根据情况改变自己的驾驶行为，同时借助先验信息提前运用自己的技能，改变通过道路转折点的路径。为了探索这种现象，提出了一种通过将先验信息（预测效果）与道路交叉点相结合的二维 (2D) 点阵模型。在道路的交汇处，车辆可以从上游进入下游的各个车道。下游的交通强度可能会根据交通比例而有所不同。为了分析所提出的模型，通过控制方法得到无控制信号和有控制信号的稳定条件，表明考虑控制信号时稳定区增大。理论研究结果表明，预测效果会影响分流交通的稳定性。数值模拟验证了理论结果，该结果显示了考虑预测效果和二维点阵模型中道路交叉口的交通流稳定性结果。
