Average buses per hour

Public Transportation. Increasing housing density and neighborhood convenience shortens trips. More people choose to walk, bike or take transit. So most public transit is provided to such convenient, pedestrian-rich areas. Of course, some otherwise convenient neighborhoods located off transit corridors might lack great service. Or, low density neighborhoods located near a subway stop might have great service. But, with these few exceptions, superior transit service is normally provided to compact, convenient neighborhoods.

A bus every 30 minutes becomes feasible above 7 hh/res ac, and every 10 minutes at 15 hh/res ac. Light rail service is feasible above 9 hh/res ac. Rapid transit is feasible above 12 hh/res ac. Public transit use increases fourfold as density increases from 7 to 30 hh/res acre.

Source of Calculations
Calculations are based upon data developed for the Location Efficient Mortgage‚ studies of the Chicago, Los Angeles and San Francisco regions by the Institute for Location Efficiency (Natural Resources Defense Council, Center for Neighborhood Technology and Surface Transportation Policy Project). The nearly 3000 neighborhoods are the Metropolitan Planning Agencies’ (CATS, SCAG and MTC, respectively) travel analysis zones, generally a census tract or two. This analysis applies to neighborhoods in metropolitan areas or within commuting distance of major job centers, not to isolated rural towns. Location efficiency lowers auto costs and can qualify you for a Location Efficient Mortgage‚.
Transit service = 2.6905 Density - 8.2799, but not below 0. [R2 = 0.30]

5 = 2 nearby buses per hour, 1 each direction
50 = frequent bus service
200 = frequent bus and mass transit service
