Efficiency Assessment of Transit-Oriented Development by Data Envelopment Analysis: Case Study on the Den-en Toshi Line in Japan

Abstract EN

Transit-Oriented Development (TOD) is an urban planning approach that encourages a modal shift from private to public transportation.

This shift can generate additional benefits from a sustainability perspective.

This study aims to assess the efficiency of TOD by applying the data envelopment analysis (DEA) method.

The ridership of public transportation is considered as the direct output characteristic of TOD efficiency, and nine indicators of ridership are selected as inputs on the basis of the core concepts of TOD.

These concepts include density, diversity, and design (3Ds).

The Tokyu Den-en Toshi Line in Japan is presented as a typical case of TOD because this line includes TOD and non-TOD stations.

Assessing and comparing the results of all railway stations reveal that almost all indicator values of non-TOD stations are higher than those of TOD stations.

The results suggest that TOD planning and programs are inefficient in terms of ridership generation.

This implication, however, may be attributed to the inadequacy of the selected indicators for TOD assessment.

The results obtained after adding operation year as input indicators and removing transfer station show that TOD stations perform efficiently and in accordance with expectations.

This response indicates that the inclusion of influential factors is necessary for equitable TOD assessment.

Therefore, other influential factors must be considered when evaluating the efficiency of TOD-based stations with different inherent attributes.

In addition, the design input with the largest impact on all inefficient units was identified, suggesting that management of bus service and railway system should be well enhanced.
