Abstract
Rapid population growths in the Delhi metropolitan area created by a strong expansion of the economic base have led to the adoption of decentralization policies for the region. A regional-scale land-use–transport model is developed which may be used for the analysis of decentralization options. The model searches for regional-development configurations that minimize the combined costs of providing urban infrastructure and of intercity transport. The objective function is a nonlinear function of the regional activity distribution, and a sequential search procedure is used to identify the least-cost alternative. The capabilities of this allocation-simulation model are demonstrated by several example analyses for the Delhi commuter region.
