摘要
Since most existing models are theory-oriented and not practically implemented, a new model is presented to optimize bus network, which takes maximum direct traveler density as objective. The model tries to achieve minimum transfers and maximum traveler flow per unit length with line length and non-linear rate as constraints. Considering the communication cost and optimization qualities, an ant colony algorithm based on the coarse-grain model is designed to solve the problem of this model. With a numerical test, the effectiveness of the model and the algorithm is verified.
