Optimal routing in complex fire emergency traffic network

We propose an new optimal routing strategy that collectively minimize the maximum ratio of betweenness to capacity in any link. The topological structure of fire emergency traffic network is studied by considering networks with a heterogeneous distribution of link capacities and with a heterogeneous transport load. At last, the theoretical derivation of the average travel time is given according to calculate link betweennesses assuming the arrival and the delivery of particles at every node.
