An Evaluation Index System for Wayfinding System and Its Research Applications: The Case of Beijing Subway Line 1

Abstract

Object: To construct a set of comprehensive evaluation index system for wayfinding systems, and conducts trial evaluation using Beijing Metro Line 1 as an example. Methods: The research followed the principle of main factors, the principle of dynamics, and used the combination of quantitative and qualitative factors to select the evaluation indexes, which includes functional, normative, safety and coordination indexes. Field tests were performed on Beijing Subway Line 1 using evaluation indexes. Results: The overall renovation time in the stations has been half a century, mainly reflected in the absence of platform doors, the dim lighting inside the stations, and the insufficient installation conditions at key intersections. In addition, Line 1 passes through mature urban areas, where the business is prosperous, and the environmental information outside the stations often change. All these also make it difficult for maintain information connecting inter-stations and out surroundings.
