ANALYSIS OF TRENDS UNDERLYING URBAN/REGIONAL IMPACTS OF TRAFFIC GROWTH

The growth of highway vehicle traffic displays self-limiting characteristics, based on national and state data. The implications of these characteristics for delays at the regional or metropolitan level, though, depend on changing trip lengths and spatial distributions. To avoid treating all regional travel growth the same, the authors of this paper present four scenarios: 1) uniform travel growth, 2) random travel growth, 3) growth in congested areas, and 4) growth in uncongested areas. The scenarios are tested using an Urban Transportation Planning System-based model adapted for this study. The scenario analyses suggest widely varying manifestations of increased travel on delay. In addition, policies that treat all travel growth the same might be more effective if modified to mirror underlying trends and alternative planning strategies.
