Abstract

This study aims to analyze the cascading failure process of traffic network in tourist attraction under unexpected emergency events, and discuss the measures to improve traffic network invulnerability. For that purpose, taking tourist attraction as the research object, the topology model of traffic network in tourist attraction is established based on Space L method. After different types of emergency events are simulated as different attack strategies, we discuss the spatial and temporal distribution characteristics and evolution process of tourism emergency events. The cascading failure model of traffic network based on load-capacity is constructed, then the main factors affecting the scale of dynamic cascading failures are given and their sensitivity are analyzed. Taking the Summer Palace in Beijing as an example, the invulnerability analysis of the traffic network is carried out and the node protection strategies with different network load are proposed. The study reveals that (a) the traffic network of the Summer Palace has a typical network characteristics of small world; (b) network load, node capacity, node attack strategy, adjacent nodes relationship, load distribution rule significantly affect the scale of cascading failure of the traffic network in tourist attraction, (c) when the network load coefficient $\delta , the cascading failure rate (CFR) can be effectively controlled within 0.2 to avoid large-scale cascading failure; (d) the scale of cascading failure can be effectively reduced by 22.14%, 40.91%, and 63.66%, after increasing the capacity of the nodes which are the top 5%, 10%, and 20% in the ranking of CFR, respectively.

Summary

INTRODUCTION

C. THE MAIN CONTRIBUTION The existing literatures provided us with tourism emergency events definition, evolution mechanism analysis, traffic network construction in tourist attraction, attack strategy formulation, and cascading failure simulation. It is necessary to study the traffic network construction model, the form and space-time characteristics of tourism emergency events, and the cascading failure model and simulation of the network. The spatial and temporal distribution patterns and rules of tourism emergency events were studied, and the cascading failure model of traffic network in tourist attraction based on load-capacity is constructed. Taking the Summer Palace in Beijing as an example, the research on the invulnerability analysis of traffic network in tourist attraction under unexpected emergency events based on cascading failure was carried out. The data of network topology structure is displayed in the form of adjacency matrix
