Evaluation of Relationships Between Ridership Demand and Transit-Oriented Development (TOD) Indicators Focused on Land Use Density, Diversity, and Accessibility: A Case Study of Existing Metro Stations in Bangkok

Abstract

Abstract The purpose of this work is to support the transit-oriented development (TOD) in Thailand. The main research objective is to explore the relationship between ridership demand and TOD indicators, which is expected to be the first question that a developer in Thailand must be able to answer in order to direct their development plan in the right direction. Using existing Bangkok metro stations as a case study, 22 variables categorized into three groups (density, diversity, and design) were collected for an 800-m buffer area around the stations. Results of the correlation analysis between transit ridership and other variables show a significant relation with the volume of transit ridership. Bus services have a stronger influence on transit ridership than railway stations and ferries (pier). Also, the interchange stations and park-and-ride buildings are found to be the main variables that correlate directly with the transit ridership numbers. Results from the principal component analysis are used to evaluate factors of TOD characteristics for the existing Bangkok metro stations, categorized into seven factor groups.
