A Recommendation Method of Barrier-Free Facilities Construction Based on Geographic Information

Public accessibility facilities play a vital role in the life and travel of the disabled and the elderly. With the increasing population of the disabled and the elderly, the number and types of barrier-free facilities are relatively insufficient and the construction location is not reasonable in most cities of China. This paper collects the geographic location information of public facilities, relevant units of disabled persons, traffic stations and barrier-free facilities in the “National Barrier-Free Construction Demonstration Zone” of Shanghai; divides a single building into several local areas; extracts eigenvalues from environmental information in the local areas and transforms them into eigenvectors to construct accessibility facilities construction model basing on the geographic information. And after experiment validation, the accuracy of the model reaches more than 95%, and part of the error of the number pf accessibility facilities could be controlled within 0.003. The application of this model can provide guidance and suggestions for the government in the construction of public barrier-free facilities, and improve the rationality of the construction of barrier-free facilities.
