  • Spatially-varying effects of environmental factors on pedestrian trips

  • Suji KimM.S. Thesis2015
  • Walking is an important transportation mode in people’s daily lives. It provides benefits in various aspects - health, environment, cost savings, and regional variability. However, walk-ing has tended to be overlooked due to developments focusing on motorized modes of trans-portation. Recently, according to sustainable and green concepts in urban and transportation, a variety of countries have begun to consider walk- friendly environments in urban design and planning and have started to study such environments. In order to implement such environ-ments, three characteristics of pedestrian trip must be considered. First, it is difficult to measure accurate and reliable pedestrian volume - the fundamental data for study about pedestrian travel. Second, traditional travel models can not apply to pedestrian travel. Third, pedestrian trip in specific areas is strongly influenced by conditions of surrounding areas. This study tried to determine the effect of environment factors on pedestrian trips in order to support such trips by overcoming these characteristics. Through geographically weighted regression, we analyzed the different local relationships. Explanatory variables were categorized into 4 sections and nine variables were derived as influential variables. The validity of the results was determined by comparing it with the results of Ordinary Least Squares regression and spatial variability test of coefficient data. And, we attempted to explain the spatial variability in view of urban and transportation planning. This research is meaningful in considering spatial differences, increas-ing performance using GWR, and providing a good foundation for the development of walk-friendly environments.
