Abstract: To solve the problem of crowd congestion caused by lack of forward looking plan for tourist blocks, a Logit type stochastic user equilibrium route choice model oriented to topological distribution and spatial syntax was proposed in view of the temporal and spatial characteristics of population flow in tourist blocks. Firstly, the topology diagram of tourism block was established based on spatial syntax theory to describe the topological invariance of complex block network. Then the traditional Logit stochastic user equilibrium route selection model was improved to simulate the crowd flow distribution of the network topology. The nonlinear Bureau of Public Roads pedestrian road resistance function was introduced to depict crowding effect characterization of the crowd considering the path travel time impedance. Finally, the road network of Ciqikou scenic area in Chongqing was analyzed. The results show that the time of the impedance evolution degree is the worst on path S₇, followed by S₈, S₁₃ and S₁₄ and that through the transformation of scenic road network, the flow of route S₇ is allocated, and the negative evolution trend of time impedance is effectively eliminated, which improves the effect of crowd counseling.

Key words: block network, crowd flow, topological, spatial syntax, temporal impedance
