| 摘要： | Currently used measures of level-of-service to evaluate the traffic condition of road sections are not necessarily linked to the perceived level-of-service by the drivers. The aim of this study is to propose a universal level-of-service measure of road traffic based on the driver's perception of the driving environment. The measure is composed of aggregated driving utility, and the utility is estimated by the driver's utility function with surrounding driving conditions. The analysis and modeling are conducted for merging sections where common driving behaviors found in other types of road segments occur. The calibrated utility function based on a set of observation data shows a fairly good reproduction capability on the behavior of the observed drivers. This means that the proposed measure reflects the individual driver's perception of the level-of-service. |
