Capacity Limitations: The capacity of TransJakarta corridor 1 is only 2,700 persons/hour/ direction, which compares unfavorably with other BRT systems in the world, such as those of Curitiba and Quito, which have capacities of 12,000 persons/hour/direction, and Bogota with a capacity of 35,000 persons/hour/direction on two lanes. One of the main reasons for Transjakarta’s low capacity is the relatively small size of its buses. Another reason is that both its buses and bus stations have only one door, reducing boarding and alighting speed.
