摘　　要：为了让行驶工况具有空间位置信息,反映道路不同位置交通服务水平、交叉口间距、信号控制对行驶工况的影响.文中将行驶工况重新定义为车速沿车辆行驶方向的空间变化过程,并分析车辆在通过路段和交叉口过程中车辆行驶状态的变化规律,以及车辆能耗和排放的变化规律.研究发现,通过聚类分析,能够按照速度和加速度不同将沿道路行驶方向车辆行驶工况有效划分为不同的车辆行驶状态;基于不同的车辆行驶状态,能够有效分析沿道路行驶方向交通行驶环境对行驶工况以及车辆能耗和排放的影响.In order to make the driving conditions have spatial position information,reflecting the influence of the traffic service level,the intersection spacing and signal control in different locations of roads on driving conditions,the driving condition was redefined as the spatial change process of vehicle speed along the driving direction of the vehicle in this paper.The change law of vehicle driving state in the process of passing through road sections and intersections was analyzed and the change laws of vehicle energy consumption and emission were analyzed.According to different speeds and accelerations,it is found that the vehicle driving conditions along the road driving direction can be effectively divided into different vehicle driving states by cluster analysis.Based on the different vehicle driving states,it can effectively analyze the influence of the traffic driving environment along the road driving direction on the driving conditions and the vehicle energy consumption and emission.
