People near transit: improving accessibility and rapid transit coverage in large cities

Many of the world’s most important cities are expanding rapidly without adequate transportation planning. People Near Rapid Transit (PNT) measures the number of residents in a city who live within a short walking distance (1 km) of high-quality rapid transit. This is a good way to estimate accessibility and rapid transit coverage in large cities. It is also a high-level proxy for the integration of land use and transport, and the fundamental first step toward creating inclusive transit-oriented development (TOD)—compact, higher-density, mixed-use, walkable development centered around transit stations.
