The Impact of Decentralization on the Journey-to-Work and Pollution
研究了城市空间分散化（人口和就业分散）对通勤出行和中心城区空气质量的影响，发现分散化会减少中心城区的出行活动，从而降低移动源污染，但最终影响可能较小。
The aim of this paper is to examine the relationship between urban spatial development, the journey to work, and central city air quality. Using a twostep model, we examine the effects of population/employment dispersion on auto work trip generation and the impact of trip making density on central city pollution. The results suggest that: (1) both population and job dispersal play a significant role in determining the spatial variation in trip making activity; (2) dispersal will, ceteris paribus, reduce travel activity affecting the central city and consequently mobile source pollution; and (3) the ultimate impact on dispersion may be small.
