Bus Rapid Transit (BRT) systems have been developed during last 30 years in Latin America in order to fulfill requirements of time, mobility, security, comfort, accessibility and environmental sustainability in growing megacities. In spite of this, many of these systems don´t offer complete accessibility for disabled people, which are estimated in around 7% to 10% in developing countries. In Cali, Colombia, only 0,89% of these persons enter higher education, and one of the principal reasons is because of barriers in the transport system. This article presents the experience of the development of a design that will allow wheelchair users access to the BRT in Cali from external feeder routes. A previous characterization was done, which included stops of these routes in four universities of the city, along with the characteristics of the bus used in these routes. According to this information, a first low cost design was proposed, which doesn’t imply important modification to the buses, and doesn´t interfere with BRT times. A concept proof was done using one of the buses and a structure similar to the proposed design. Wheelchair users and other assistants stated that it is a cheap system that doesn´t require high cost maintenance, providing a practical solution to the problem.
