模拟电路的信号交叉口交通流模型

为了定量描述信号交叉口交通流的释放过程,以RLC电路的电流模型为理论基础,对交叉口交通流释放规律进行了研究。类比信号交叉口与电路相似的脉冲特性,建立了信号交叉口交通流量释放模型,并利用长春市典型交叉口实际交通调查数据对模型进行了验证。结果表明,模拟电路信号的交叉口交通流模型可以定量描述交叉口交通流释放规律。

Traffic flow model by simulating circuit at signalized intersections

The dissipation process of the traffic flow at the signalized intersection was studied based on the theory about the electric current model of the RLC circuit.By analogy of the similar pulsed characteristics of the electric circuit and the signalized intersection,a traffic flow dissipation model was built an verified by the practical traffic survey data at the typical intersections of Changchun city. The results show that the traffic flow model by simulating the electric circuit at the signalized intersections can describe quantitatively the dissipation process of the traffic flow at intersections.
