Applicable Prevention Method of Braess Paradox in Urban Traffic Flow Guidance System

Highlights

  • Traffic congestion is gradually becoming one of the most serious social problems

  • One of the most effective solutions to this problem is the establishment of Urban Traffic Flow Guidance System (UTFGS) which could provide the optimum path for travelers before or during the trip based on real-time traffic information in the road network[1]

Summary

Introduction

Traffic congestion is gradually becoming one of the most serious social problems. One of the most effective solutions to this problem is the establishment of Urban Traffic Flow Guidance System (UTFGS) which could provide the optimum path for travelers before or during the trip based on real-time traffic information in the road network[1]. As the overreaction and concentration of drivers, both the static and the dynamic UTFGS may cause a problem of Brass Paradox which may unbalance traffic volume and weaken the effectiveness of navigation information[2]. Even worse, such case will degrade users’ trust in the UTFGS and bring very adverse effects to the application and popularization of the navigation technology. For a applicable solution of the Brass Paradox problem in UTFGS, we will first talk about the formation mechanism and prevention method of it at the beginning
