Annex 7 Innovative Approaches to HCBRT Corridor Selection: Mixing with General Traffic

Exclusive Bus Streets with Special Access Provided for Residents and Loading

In this case, a section of public street is designated by municipal by-law or decree, (depending on the institutional arrangements) as being for preferential use by public transport. Access is permitted to buildings for residents, loading, or even customer parking, provided that BRT operations are not affected.

This is very common in central areas of older or historic cities, where roads are narrow and curved. The example below in Figure 1 shows the central area of Quito, Ecuador. The trolleybus can clearly be seen sharing the road on a one-way section. The right-hand lane is preferential for public transport, but access is permitted to adjoining properties.

This central part of the busway is also operated as a two-way, bus only street, in which the narrow roads have a RoW of around 6m and have many sharp curves. As can be seen in Figure 2, the articulated unit can negotiate these streets safely, but at low speed.

In Curitiba, Brazil, as illustrated in Figure 3, the HCBRT units can be seen using two-way reinforced concrete lanes, which allow other users access to property and even a right turn across the busway (signalized as preferential for buses).

In severely constrained central areas, it may be necessary to search for solutions that go beyond the existing road space. Figure 4 above shows the design of a busway RoW that not only preserved access, but also allowed development to take place.

It is also often assumed that if there is a constraint, mass transit must go round, over or under the problem. Sometimes costs can be kept much lower by allowing the ‘problem’ space to extend over the transit. An example is shown below: a solution to a vibrant street market in San Salvador that blocked the only available access for preferential BRT use only. The concept involved raising the street market up a level, so that the market continues to exist, but on a simple steel structure, above and integrated with the surrounding commercial area. Access is by stairways on the side roads.
