基于出行链的建成环境对居民小汽车通勤出行的影响

城市建成环境对居民出行,尤其是小汽车通勤出行的影响是交通需求预测的基础性命题,长期受到关注.已有研究大多以单次出行作为研究对象,较少关注出行链影响下的出行协同决策问题.论文基于2017年广州市居民活动日志调查数据,采用Logistic模型检验了出行链视角下城市建成环境对工作日选择小汽车通勤出行的影响.研究发现,出行链中...

Impact of the built environment on residents'car commuting based on trip chain

The impact of urban built environment on residents' travel behavior, especially car commuting, is a basic topic of traffic demand forecasting, which has received considerable research attention. Existing studies mainly focused on single trips and paid less attention to the collaborative decision making under the influence of trip chains. By using the logistic model and detailed activity diary data collected in Guangzhou City in 2017, this study investigated the relationship between urban built environment and car commuting on weekdays from the trip chain perspective. Empirical results indicate that there is an interactive relationship between non-commuting trip in the trip chain and the built environment of the workplace and residence, which synergistically affects residents' commuting modes. On the one hand, the non-commuting trip time (before or after the commuter's trip) make difference in the relationship between the built environment and commuting mode choice. On the other hand, the mutual influence of several built environment factors—residential area, work location, and non-commuting activity—determines the commuting behavior. Therefore, the extension of the results may provide new thoughts for predicting individual traffic behavior and traffic demand based on individual models.
