GRT Runways
The Guangzhou BRT system will feature dedicated median bus lanes, with two lanes at stations (to allow overtaking) and one lane between stations.
BRT runway
The BRT roadway will have overtaking lanes at stations and single lanes between stations. Overtaking lanes at stations are essential for Guangzhou to achieve the high capacity which is needed. The roadway will be strengthened in the vicinity of stations. The BRT runway will be paved in a different colour to assist with enforcement of lane segregation. Lane dividers will be used, though it will be possible for BRT vehicles to enter and leave the dedicated lanes at many points along the corridor.
Intersecting BRT corridors
For the special case of intersecting BRT corridors, a BRT-only elevated roundabout is proposed as a general design approach (see rendering).
