This study presents the methodology used by TRANSMILENIO S.A. –the company in
charge 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-articulated
buses. This process demanded a redefinition of the frequencies, stops, and type of bus for all
routes in the system. Therefore, a line scheme was selected based on the number of trips
between corridors. A non-linear optimization model was then used to establish an initial
route 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 were
tested for the execution order of algorithms. The alternative to implement was selected based
on compliance of the defined restrictions. Algorithms were iteratively run. Between
iterations, 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, and
compliance of restrictions are part of this study's discussion. Particular relevance and effects
of 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 own
route design process.
