located as close to the station as land availability allowed. Rail transit impacts on
developments in existing built-up areas were generally less strong [

23.5.3 Con
guration and Design
Guidelines for rapid transit con
guration, design and operations are as follows:
(a) Lines should radiate from the city center. Generally they should pass through
the CBD rather than terminate there (commuter railroads are a possible
exception).
(b) Generally, they should be grade-separated (e.g., subways in downtown areas).
Cross town lines, when provided, should connect to the radial lines.
The CBD end of a rapid transit trip offers an excellent opportunity for travel time
saving over a trip by automobile. It is essential, therefore, to maximize service
convenience by placing routes through areas of heavy demand, and providing
frequent stations, and interconnecting stations and mezzanines with major corridors
for pedestrian movement. To the maximum extent possible, station facilities should
serve as their own CBD distributors
—
thereby minimizing transfers to other transit
vehicles or changes in travel mode.
