Method for Calculating Intersection Diversion Ratio Based on Network Equilibrium

  • Received Date: 22 Jan 2007
  • Publish Date: 25 Apr 2008
  • A method for calculating intersection diversion ratio was proposed to study the influences of space distribution of traffic demands on traffic network bottlenecks.Link proportion,intersection diversion ratio and their relationship were investigated over stochastic user equilibrium networks.On the basis of Dial load, the formulae for single and double link proportions were derived following the probability principle and weight theory.A method for calculating intersection diversion ratio and flow was presented based on the obtained link proportions and the relationship between MSA algorithm and Dial load.A numerical example was presented to illustrate the feasibility of the proposed method.
