Analysis Of Pedestrian Traffic Mechanism Based On Pedestrian Flow Characteristics

As the rapid urban development and the population of city in the world expansion, thepedestrian traffic congestion has become one of the major problems of cities. Studying on themechanism of transportation of the pedestrian flow, grasping exactly the characteristics of thepedestrian flow, managing and controlling effectively the public space of pedestrians, has theimportant meaning to solve the urban transportation problem. This article will use empiricalanalysis, from two perspectives what were the micro individual characteristics and macrocluster state, to study the mechanism of traffic flow line in the complex space environment.The individual characteristics is the root of the macroscopic phenomena, the macrophenomena is the external representation of many micro individual cluster’s the general state,and the parent map by pedestrians’ macro state variable is a multidimensional state spaceforms of expression. Therefore, the main research work this article reflects in: Firstly, with agreat number of pedestrian traffic characteristics based data, collecting the data of multiplescene space with the Chinese’s characteristics to construct traffic fundamental diagram, toexplain the traffic flow state collapse phenomenon do exist actually. Secondly, according tothe influence of individual characteristics of traffic behavior, analyzing the influence of socialforce model to the role of the individual traffic behavior, and optimizing the social forcemodel, as putting forward by using the space analysis method can demand a careful analysisof the macro social individual characteristics influence; Thirdly, from the complex spacetransportation demand perspective, it does detailed analyze the space internal flow line on thecharacteristic, illustrates the complex space environment on the mechanism of pedestriantraffic influence; Finally, by using the computer simulation software to simulate the case,further describe the transportation characteristics of traffic flow in the complex spaceconditions.The mainly innovation of this article:(1) Through the empirical method to establish the pedestrian fundamental diagram oftraffic flow, and according to the fundamental diagram to make transportation mechanismanalysis;(2) According to the characteristics of individual pedestrians, construction space and speed relation model first time;(3) Optimization of the social force model;(4) Make use of multiple observation area traffic parameter distribution map comparisonanalysis methods, effectively reflect the complex space for pedestrian traffic mechanism.The macroscopic phenomena traffic mechanism analysis method, which has beeninvolved in this paper with the combination of the characteristics of micro individuals and themacroscopic phenomena, is an exploration to the research method of the pedestrian trafficflow characteristics, and it can provide certain theoretical basis for the city group’sorganization and management of the pedestrians.
