The sole implementation of a Bus Rapid Transit System -BRT parallel to the conventional is not enough to guarantee meeting users and operators?needs within the Metropolitan Area of Bucaramanga -MAB, Colombia. As time passed, these systems became inefficient; as a result, users started looking for alternative non-formal transportation means and the State incurred in additional financing for the permanence of the system. This paper seeks to bolster the modes of public transportation through a fare strategy that agrees with the actual distances travelled by the user. In other words, the purpose of this work is to establish tariff zones for the AMB to differentiate between those users moving in short journeys and those who travel long distances to get to their destination in order to create a balance between the users? benefit, the quality of the travel, and the operation costs of BRT.
