Improving bus travel times with passive traffic signal coordination
Estrada Romeu, Miguel Ángel; Trapote Barreira, César; Roca Riu, Mireia; Robusté Antón, Francesc (2009)
Text en actes de congrés
Accés restringit per política de l'editorialA simulation optimization model is outlined: traffic signal offsets in intersections are calculated to minimize the travel time of bus users in an urban network. The model considers a passive signal priority system and ... -
Learnings from urban bus network change
Trapote Barreira, César; Robusté Antón, Francesc; Badia Rodríguez, Hugo; Estrada Romeu, Miguel Ángel (Transportation Research Board (TRB), 2016)
Comunicació de congrés
Accés restringit per política de l'editorialWe present a strategy to improve bus service in urban networks that gives equal or better transit service and saves public resources: a win-win strategy. It consists on changing from “direct lines” to mobility centers from ... -
