This paper focuses on determining how ITS systems can support the implementation of BRT corridors. It contains the definition of the main players directly involved or benefited by ITS. A proposal is also made for a Public Urban Transportation ITS architecture to be applied on BRT corridors. To do so, it was adopted a systematic identification process for ITS functionalities and its classification into groups of services. This approach can be used as a reference to improve ITS functionalities in future BRT corridors projects.

The relationships between the entrepreneurs, the managing agencies and society as a whole have evolved towards the establishment of partnerships that allow for the improvement of infrastructure and services related to economic and social progress achieved in the last two decades. The lack and poor quality of PUT offered in medium and large cities of Brazil, together with factors such as economic growth and a policy of encouraging private transport, caused an undesired migration of PUT towards private transportation. In this context of urban mobility deterioration there is a need for change. The BRT (Bus Rapid Transit) has emerged as a solution that can potentially completely change the current situation because it is one of the recommended options for medium capacity transportation systems. It is favored by cost-benefits trade-offs and by implementation periods versus deployment complexity [1]. These systems have become international references of PUT highly efficient, with quality and low costs. Several cities in the world use the BRT concept as the backbone for public policy for urban development [2]. BRT´s have high operating speed, greater capacity vehicles, segregated lanes, external billing, electronic payment, level boarding, priority signal control. It can be deployed gradually, initially at the most critical points or greater impact, evolving over time until it reaches its plenitude. In order to allow BRT´s reaching its high levels of efficiency (less costs and higher reliability), safety and comfort for PUT users, it is essential to use advanced communication and information technology (CIT). This is a concept that clearly relates the evolution of transport services with the combined technologies of Intelligent Transportation Systems (ITS).
