Road Improvement Effectiveness from a Quality of Life (QOL) Perspective

This study analyzed “where” and “what” benefits are received by road projects and “who” receives these benefits, using a Quality of Life (QOL) indicator based on the effects attributed to the residents. A survey of about 3,000 people indicated that the weights of a living environment, including road drivability, vary depending on personal attributes. A case study of an expressway project showed that multifaceted, regional effects, such as improved medical access and tourism, can be comprehensively represented without compromising the purpose and characteristics of the project. In addition, the evaluation from an individual QOL perspective identifies social and spatial inequalities and provides a scientific basis for achieving diversity and inclusion in the cities.
