The performance of a BRT corridor with a single lane per direction and no overtaking is investigated, in terms of capacity and operating speed, by simulating 324 alternative scenarios. The simulation runs comprised a range demand levels, boarding and alighting rates, station spacing, vehicle loading, number of berths per station, and traffic signal positioning in relation to stations. The analyses reveal that such BRT corridor, when operated by articulated buses, can achieve a capacity around 15,000 pass/h/dir along its critical section and an operating speed of 23 km/h. Preliminary statistical analysis enabled the estimation of a regression model repre- senting the impact of BRT design elements on the operating speed. The findings could provide useful insights for designers of high- performance BRT corridors.
