摘要

行人服务水平受交通条件、道路设施条件和环境条件等因素的影响。行人流量是影响PLOS的关键因素，因为在不同的行人流量下，行人对人行道的视觉范围和各影响因素对人行道的影响程度不同。为了更准确地评价PLOS，本文将行人流率分为6个阶段。然后，采用Spearman秩相关法分别提取了影响行人满意度的交通状况、道路设施状况和环境状况在每个人流量下的显著影响因素;最后，提出了基于行人流量分类的公共交通系统多因素评价方法。此外，采用模糊神经网络方法对模型进行训练。试验表明，基于模糊神经网络的不同行人流量下的公共科学图书馆综合评价模型准确率达到92%，大大高于以往研究的模型准确率。

MODELLING PEDESTRIAN LEVEL OF SERVICE ON SIDEWALKS WITH MULTI-FACTORS BASED ON DIFFERENT PEDESTRIAN FLOW RATES

Pedestrian Level of Service (PLOS) is influenced by the factors of traffic conditions, road facility conditions and environmental conditions. Pedestrian flow rate was the key factor influencing PLOS 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 PLOS more accurately, this paper classified pedestrian flow rates into 6 stages. Then, 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 PLOS with multi-factors based on classification of pedestrian flow rates was put forward. In addition, the models got training with fuzzy neural network method. The test showed that the accuracy of the comprehensive evaluation model of PLOS under different pedestrian flow rates based on fuzzy neural network reaches to 92%, which is much higher than the model accuracy of previous researches.

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
