Accessible Assessment for Sidewalk Based on FAHP-TOPSIS Method

Conducting a scientific assessment to reflect the level of accessible facilities on roads is of great significance for guiding the construction. This study focuses on the accessible travel needs of special users such as blind, disabled, and elderly on sidewalk facilities. Around the travel demand of sidewalk, tactile ground surface indicator, curb ramp, and other auxiliary facilities are also formulated. Then, it established the assessment methodology, which combines fuzzy analytic hierarchy process and technique for order preference by similarity to ideal solution. Finally, it selects the sidewalk of trunk and secondary roads in the Guangzhou center district as the experimental. The evaluation results were divided into three categories: poor, general, and excellent. The improvement strategy is put forward from daily maintenance, special renovation, and overall improvement. Research has shown that the assessment results are consistent with the objective cognitive. It verifies the objectivity and practicability of the assessment method.
