The document summarizes the experiences during the first year of implementation of several Bus Rapid Transit (BRT) systems in Mexico. It describes problems encountered in the Metrobus lines in Mexico City including operational issues, challenges with fare payment technology, and difficulties with negotiations. The Ruta system in Puebla also faced planning, design, and financial problems, especially with Line 1. The Mexibus lines in the State of Mexico similarly struggled with negotiations, fare integration, and invasions of dedicated lanes. Key lessons learned included the need for better right-of-way enforcement, ensuring fare systems and driver training are ready, incorporating expert advice in planning and design, and thoroughly understanding existing transit systems before negotiations.
