AB This study presents the methodology used by TRANSMILENIO S.A. –the company incharge of managing the BRT lines in Bogotá, Colombia– to renew its operational design.TRANSMILENIO S.A. is increasing its bus fleet by acquiring higher capacity bi-articulatedbuses. This process demanded a redefinition of the frequencies, stops, and type of bus for allroutes in the system. Therefore, a line scheme was selected based on the number of tripsbetween corridors. A non-linear optimization model was then used to establish an initialroute design that could satisfy passenger demand in the morning rush hour.Five algorithms were implemented to adjust the initial route design to the actual restrictions,namely, fleet and bus capacity at stops. The algorithms modified the type of bus employed,the defined stops of routes, and eliminated low demand routes. Different alternatives weretested for the execution order of algorithms. The alternative to implement was selected basedon compliance of the defined restrictions. Algorithms were iteratively run. Betweeniterations, a trip assignment model was used to adjust route frequencies based on demand.The execution order of algorithms, its impact on the level of service indicators, andcompliance of restrictions are part of this study's discussion. Particular relevance and effectsof each algorithm are also analyzed. Both methodology and results might be tested, adapted,and improved in further studies by other BRT systems as a reference or input for their ownroute design process.
