Mobility and transportation are the keys to a competitive city. There is a close relationship between the development of a transportation infrastructure and the economic growth of a city. Efficient transportation improves the live of citizens and brings production centers closer to markets, thus favoring commerce. This article presents a model for the planning and deployment of services in the Intelligent Transportation System [ITS] of Colombian cities. This model takes regulations, frameworks and standards into account. The planning and deployment of a traveler information service is shown as a practical application. An experimental prototype of this service is currently being tested at three locations in Cali, Colombia.
