The growth of mass transport is associated with population growth, and is one of the alternatives to increasing traffic congestion and improving the environment. These transport systems arise in response to specific bans on the use of private vehicles in some cities and for the proper management of mobility. From this new transport scheme, operations research makes use of mathematical modeling for the study and implementation of efficient methods that optimize the problems of programming and allocation of the system, complying with the norms and specific restrictions of the same improving the flexibility Operating system. Due to the high vehicular congestion and the deficiency of public transport, in Colombia the public transport policy was adopted as the transformation of urban transport systems in the main cities of the country. CONPES 3167 of 2002 establishes the policy to improve the urban public passenger transport service, which mainly defines for cities with a population greater than 600,000 inhabitants, to implement integrated mass transit systems (SITM), under a scheme of Lanes exclusively destined to the operation of high capacity buses, with physical and tariff integration, with feeder routes, operation and systemized control and the private capital linkage for the operation of buses and technology. A key element in a mass transit operation is to optimally manage its resources.
