Abstract: Transport junction has plays an important role in promoting the economic development
of economic circle in China. On the based of aiming at the minimization of the junction
construction costs and the transportation costs, the economic influence of the cities where the
junction locate was considered, and the model was established to locate the transport junction in
economic circle. In order to seek the optimal solution quickly, hybrid niche genetic simulated
annealing algorithm was solved the model. The example of numerical analysis shows that this
model can locate the traffic junction as the goal of the total cost minimizing and the economic
influence maximizing of the junction, and the optimal solution of the model algorithm can be
faster. Comparing to the traditional model of junction site, it integrates the economic and
transportation characteristics of economic circle, and take the Yangtse Delta economic circle as the
example, the analysis result tallies with the facts.
