基于用户感知的城市道路交通服务水平评价方法

Level of Service Evaluation of Urban Streets Based on User Perception

摘要:

从用户感知的角度构造了适用于服务水平评价的各聚类指标的白化权函数，提出了城市道路交通服务水平评价体系.用此方法对上海市浦东新区部分路段的服务水平进行评价，并与问卷打分结果及仅考虑交通设施的服务水平评价结果进行对比.结果表明，基于用户感知的灰类白化权函数聚类的城市道路交通服务水平评价方法能较好地与主观评分结果匹配，具有较高的精度.

Abstract:

An evaluation method of level of service (LOS) for urban roads considering user perception was proposed based on the grey whitenization weight function theory. The whitenization weight functions of different indices, which is suitable for LOS evaluation, were constructed. A test of LOS evaluation of several urban streets in Pudong District, Shanghai was conducted. The efficiency of the model was examined through the comparisons with the results of scoring and LOS evaluation without taking user perception into consideration.
