Abstract:

Pedestrian level of service is influenced by the factors of traffic conditions, road facility conditions and environmental conditions. Pedestrian flow rate was the key factor influencing pedestrian level of service for the reason that pedestrians’ visual scopes of pavement and the influencing degree of each influencing factor on sidewalks was differed under different pedestrian flow rates. In order to evaluate pedestrian level of service more accurately, this paper classified pedestrian flow rates into 6 stages, then the influencing factors of pedestrian level of service were determined for each stage, and multi-factor evaluation models for pedestrian level of service based on different pedestrian flow rates was developed with the method of fuzzy neural network. Firstly, behavior-observation method was adopted to classify pedestrian flow rates base on pedestrians’ traffic states. Then, pedestrians’ satisfaction questionnaire survey about 132 typical sidewalks in Beijing was carried out. Significant influencing factors of traffic conditions, road facility conditions and environmental conditions, which influenced pedestrians’ satisfaction, were extracted respectively under each pedestrian flow rate by Spearman rank correlation method. Finally, the evaluation method of pedestrian level of service with multi-factors based on classification of pedestrian flow rates was put forward. And the models got training with fuzzy neural network method. The test showed that the accuracy of the comprehensive evaluation model of pedestrian level of service under different pedestrian flow rates based on fuzzy neural network reaches to 92%, which is much higher than the model accuracy of previous researches.
