Level of Service Evaluation of Urban Streets Based on User Perception

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.
