摘要

Building on self-reports of a sample of 336 residents who have often experienced a shift from low to high density living in Tehran, this study tests a hypothesis suggesting that, in the context of attempts to escape and restore from chronic noise, contact load, and the sense of encapsulation, a compact city might increase discretionary car travel. Findings support the hypothesis as these density stressors increased the car travel time of 30-48% of respondents by at least 7-24% for escape and restoration. This appears to offset the trip-reduction benefit of higher density living. If a 5% reduction is assumed in car travel distance in the sample districts in the context of density, and, under the optimistic scenario, that the time-distance ratio is 1 in high density areas, this finding feeds into the conclusion that high density might have had no positive effect on, or even increased to a limited degree, the overall time of car travel. Caution is, however, advised in the direct application of these findings because of sample and literature adaptation limitations. (C) 2017 American Society of Civil Engineers.
