The operating costs of a vehicle depend on variety of factors generally grouped under the two headings of standing costs and running costs. On the other hand, the running costs are function in the traveled kilometers. The aim of this paper reduces the running costs of the public transport buses by minimizing the non-productive distance, where the non-productive distance are the distance between garages and first bus station to start the trip and inverse. The proposal model is based on using the transportation technique for minimizing the total non-productive distance by redistribution the buses on their garages. Using this model is powerful for minimizing the running cost of public transport companies, addition to reducing the bus emission and saving the energy. The results indicate that significant information gained for minimizing the total non-productive distance by redistribution the buses on garages that will save the extra driving that helps for saving the fuel consumption, oil consumption, spare parts,.., and reducing the emission and the congestion traffic problem.
