Abstract

Development of non-motorized modes of transportation has recently become a common trait among urban planners toward sustainable transportation, and walkability has been introduced as one of the most interesting concepts in the past two decades. A number of researchers put efforts to develop walkability indices (WIs) to show the status of walkability for specific zones. However, further investigation has not been conducted to account for the effect of trip purposes on WI. The literature presented transportation network design (design), land use diversity (diversity) and population density (density) as main built environment criteria and previous studies have used these criteria to develop different indices to capture walkability. In this paper, the concept of WI is developed based on the zonal walk share. Therefore, a WI has been developed and then calibrated across three specific trip purposes (i.e., job, educational and shopping) in addition to all of the trips on 112 Traffic Analysis Zones (TAZs) of the city of Rasht, Iran. According to the result of this study, diversity was found to be the most prominent criterion with the WIs. Furthermore, WI was discovered more beneficial for describing the term of walk share in shopping trips than other trip purposes.
