Abstract:

In order to meet people's needs for barrier-free travels and evaluate barrier-free rail transit environment from safety perspective, an evaluation index system was established, and its weight was determined by using EWM. Then, with data of 907 citizens from Changchun as samples, the city's barrier-free rail travel environment was assessed by using GRA from the aspect of POE. Finally, factors influencing construction of such an environment were analyzed by adopting multiple linear regression model. The results show that while building rail transit environment for barrier-free travels, the most important indicators include guidance of such facilities, safety of tools, voice broadcast or notice boards, convenience of ticket purchase, willingness of surrounding people to help, etc. It also indicates that the influencing factors of satisfaction include maintenance and repair of the facilities, and application of information technology, etc.

Key words: barrier-free travel, rail traffic environment, entropy weight method (EWM), post occupancy evaluation (POE), grey relational analysis (GRA)
