Nowadays, more than half of the world s population lives in cities. Displacement in the urban area through the use of public transportation is hampered by poor planning of transport routes and networks, long travel times, increased ticket costs and waiting times, etc. As a consequence, the search for more efficient operations in the urban public transport system has increased in order to meet the transport needs in a more sustainable way. After the literature review related to the urban public transport network design problem, the method proposed by Aquino (1980), applicable to urban bus networks, was chosen. By means of the program s modernization of the chosen method and the improvements in it, the number of routes defining the connected network has decreased. The overflow number on the network has been minimized to zero with a smaller set of routes. Analysis of indicators and profitability of the routes that minimize the number of transfer in the network, allows the planner to have an overview of the behavior of these routes allowing to make decisions keeping the initial requirements and the objective of study. The developed method program, adapted to a modern language, C plus plus, offers both an academic and a professional environment an easy application tool to solve the Urban Public Transport Network Design Problem. Potentially contributing to the increase of the efficiency of the planning process and, therefore, to the reduction of nonconformities of the transport service, resulting in cost savings for the companies that provide this service.
