The simultaneous impact of residential and employment decentralization in the form of multinucleations on patterns of commuting concentration and dispersion is examined for the Washington metropolitan area with 1980 data. Because of the area's generally white-collar labor force, the impact of segregated occupational groups is minimized and it is possible to examine strictly the spatial dimensions of commuting dispersion. Commuting becomes increasingly more dispersed from the center of the area to about 12 miles outward. Beyond that point, the patterns of commuting become considerably more complex, responding to a wide range of sizes of employment in a widely dispersed pattern of nucleations. In some sectors, commuting dispersion remains somewhat constant. In one sector, commuting patterns revert to some level of concentration, possibly responding to a somewhat unique situation of employment concentration along a corridor. These findings contribute to the recognition that tomorrow's transit structure cannot rely on its traditional form, but must become more selective. |
