【摘要】:為避免雙向通道行人流堵塞,建立了對向行人流反饋控制模型?紤]了對向行人流的干擾特性,利用社會(huì)力模型的勻速條件推導(dǎo)了對向行人流基本圖。由于行人密度沿通道分布不同,按照行走方向不同,將雙向通道分為多個(gè)分通道,采用狀態(tài)空間方程建立了基于行人流量守恒的對向行人流系統(tǒng)動(dòng)力學(xué)模型。為滿足對向行人移動(dòng)需求,提出對向行人流均衡控制目標(biāo),并建立了線性反饋控制模型。該模型可通過實(shí)時(shí)調(diào)整行人速度和通道兩端的行人流入量,使得通道行人密度收斂于臨界密度,從而最大化通道行人流量,提高通道服務(wù)水平。本文模型可以作為解決行人流和道路交通實(shí)時(shí)控制問題的普適方法。
[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.
