– Conclusion
BusRT – BRT Modeling softwareSeptember 2006
High capacity BRT
– Success of BOGOTA and CURITIBA – High capacity similar to MRT
• Large right of way : 2x2 or 2x1 lanes• Hierarchy of PT network (BRT + feeders)• High quality of service• Different services (Express, Direct, Normal) • Modern buses• Adapted stations (ticketing on stations)• 2 to 3 modules per station• ITS
2 TYPES OF BRT
BusRT – BRT Modeling softwareSeptember 2006
2 TYPES OF BRTUrban BRT (2*1 lane)
– Huge success in Europe and mainly in FRANCE (Bus à Haut Niveau de Service)
– Transformation of normal bus lines into BRT (segregated right of way)
– Capacity similar to LRT and Tramways– Focus on the urban integration– Improving the quality of service (speed, regularity)– Modern Busway (guidance, ITS…)
BusRT – BRT Modeling softwareSeptember 2006
CURITIBAComplete Network using only buses
Different types of corridors:- Express corridors 72km- Feeders 270 km- Inter-district corridors 185km- Normal bus lines 573km
Different types of services- Bi-articulated 20km/h- Direct 30km/h- Conventional: 18km/h
Express corridorsInter-districtFeeders
Urban transfer terminal
Metropolitan transfer terminalEarly stage of planning
High capacities with Buses (270 p/bus)
Cost effectiveness (3 million US$/km)

– BRT relevance in developing countries:• 10000 ppdph single track• 20000 to 30000 ppdph double track
– Mode relevance: Diagnosis & planning• Significant number of criteria• Uniqueness of each city
– BRT Evolution: Long term planning• Metro project (CURITIBA)• BRT Network (BOGOTA)
