【摘要】：为避免双向通道行人流堵塞,建立了对向行人流反馈控制模型。考虑了对向行人流的干扰特性,利用社会力模型的匀速条件推导了对向行人流基本图。由于行人密度沿通道分布不同,按照行走方向不同,将双向通道分为多个分通道,采用状态空间方程建立了基于行人流量守恒的对向行人流系统动力学模型。为满足对向行人移动需求,提出对向行人流均衡控制目标,并建立了线性反馈控制模型。该模型可通过实时调整行人速度和通道两端的行人流入量,使得通道行人密度收敛于临界密度,从而最大化通道行人流量,提高通道服务水平。本文模型可以作为解决行人流和道路交通实时控制问题的普适方法。
[Abstract]:In order to avoid pedestrian flow blockage in two-way channel, a feedback control model for directional pedestrian flow is established. Considering the interference characteristics of the opposite pedestrian flow, the basic diagram of the opposite pedestrian flow is derived by using the uniform speed condition of the social force model. Due to the different distribution of pedestrian density along the channel, the bidirectional channel is divided into several sub-channels according to the walking direction. The dynamic model of the opposite pedestrian flow system based on the conservation of pedestrian flow is established by using the state space equation. In order to meet the demand of directional pedestrian movement, the objective of directional pedestrian flow equilibrium control is proposed, and the linear feedback control model is established. The model can adjust the pedestrian speed and pedestrian inflow at both ends of the channel in real time, so that the pedestrian density of the channel converges to the critical density, so as to maximize the pedestrian flow and improve the service level of the channel. This model can be used as a universal method to solve the real-time control problems of pedestrian flow and road traffic.
