This paper reports results from a detailed travel diary survey of 2125 residents in the South Bay area of Los Angeles County - a mature, auto-oriented suburban region. Study areas were divided into four centres, typical of compact development or smart growth, and four linear, auto-oriented corridors. Results show substantial variation in the amount of walking across study areas. Trips are shorter and more likely to be via walking in centres. A key to the centres' increased walking travel is the concentration of local shopping and service destinations in a commercial core. Yet the amount of business concentration that is associated with highly pedestrian-oriented neighbourhoods is from three to four times as large as what can be supported by the local resident base, suggesting that pedestrian-oriented neighbourhoods necessarily import shopping trips, and hence driving trips, from larger surrounding catchment areas. The results suggest both land use and mobility strategies that can be appropriate for suburban regions.
本文报告了对洛杉矶县南部海湾地区 2125 名居民进行详细旅行日记调查的结果——这是一个成熟的、以汽车为导向的郊区。研究区域分为四个中心,典型的是紧凑式发展或智能增长,以及四个线性的、以汽车为导向的走廊。结果显示,研究区域内的步行量有很大差异。在中心地带,行程更短,更有可能通过步行完成。中心地带步行出行增加的一个关键因素是商业核心区集中了当地的购物和服务目的地。然而,与高度适合行人的社区相关的商业集中程度是当地居民基础所能支撑的三到四倍,这表明以行人导向的社区必然会从更大的周边集水区输入购物出行,因此也输入驾车出行。研究结果为郊区地区提供了适宜的土地利用和交通策略。
