A method is developed to simultaneously select routes and assign frequencies for a bus transit system. The method is intended (a) to concentrate the flow of passengers on the road network in such a way that the sum of passenger riding-time cost and operation cost is minimized, (b) to generate a large set of possible bus routes that satisfy certain constraints, and (c) to simultaneously select the routes and their frequencies so that the number of transfers saved in the network is maximized. Heuristics are used for the concentration of flow and generation of routes, and linear programming is used to select routes and their frequencies. The model was applied to the design of a bus transit system for the city of Ahmedabad. Four alternative networks with 514, 492, 426, and 402 links, respectively, were evaluated for the concentration of passenger flows, and the minimum cost (riding-time cost plus operation cost) was obtained for the network of 426 links. This network was used to generate 457 feasible routes. A total of 421 turning movements for the network was identified. The optimal routes and their frequencies were obtained by the linear programming model for three different operating fleet sizes of 670, 750, and 790 buses, respectively.
