A density gradient will (The Kentlands, MD) (Las Colinas, TX) maximize transit ridership. While densities may decline with distance from stops, they will av- erage at least the threshold values within the quarter mile service area around stops. #2 Mix of Land Uses #3 Short to Medium Length Blocks There has been a trend toward longer and longer blocks, and correspondingly fewer and The old rule of thumb is that seven units per As important as high residential densities, fewer intersections within development and re- acre are required to support basic bus service. perhaps more important, are high employment development areas.
