Abstract

Abstract

In order to study the dynamic characters of traffic flow in large-scale activity, the spacial and temporal influences and traffic management under emergency were analyzed, static multi-path traffic assignment algorithm and cell transmission model(CTM) were combined, and a quasi-dynamic assignment algorithm was proposed.A small network was simulated, the jam times of intersections were calculated, and the forming and dissipating characters of traffic jam under emergency were studied.Different effects of two traffic management schemes on traffic flow were contrasted.Analysis result indicates that the average vehicle delays of two schemes are 197 s·pcu^-1 and 232 s·pcu^-1 respectively, scheme I is better than scheme II.So quasi-dynamic assignment algorithm can quantitatively evaluate the effect of traffic management scheme under emerggncy.
