PPIAF supports .Bus rapid transit (BRT) systems, which can be the most efficient way of improving public transportation services in urban areas. BRT is a form of Urban transport and refers to a variety of public transportation systems using buses that provide faster, more efficient service than an ordinary bus line. Often this is achieved by making improvements to existing infrastructure, vehicles, and scheduling. The goal of these systems is to approach the service quality of rail transit while still enjoying the cost savings and flexibility of bus transit.
BRT systems can have significant impacts in terms of climate change mitigation by reducing greenhouse gas emissions, or responding to the challenges that result from rapid urbanization and decentralization.
