Commercial Value Assessment of “Grey Space” under Overpasses: Analytic Hierarchy Process

Abstract

Although the rise of urban overpasses has optimized the urban transport system and improved the spatial structure of the city, the use of space under overpasses has many problems, and they can be dark, short, unpleasant, and abandoned spaces which are full of girders and include ill-shaped areas in some places. This study aims at the recent study of space utilization under overpasses. Taking the Xudong district in Wuhan as an example, the multistandards weight analysis was conducted to evaluate the value of the commercial form of the “grey space” under overpasses and analyzed the feasibility of commercial forms.
