摘要
天气状况是影响城市快速路交通运行效率的重要因素。本研究的目的是利用智能交通系统汇聚的多源、异构海量固定车检器数据研究交通运行效率计算模型,并结合气象站降雨检测数据分析降雨对路网运行效率的影响程度。结果表明不同区域路网运行效率受降雨影响存在显著差异,降雨强度对路网运行效率影响为正相关。
Weather conditions are important factors that affect the efficiency of urban expressway traffic.The purpose of this paper construct traffic efficiency model using traffic data from intelligent transportation system(ITS).Then analyzingthe effects of rainfall on urban road network efficiencycombined with meteorological station rainfall detection data.The results show that there was a significant difference between differentpart of road network affectedby rainfall,and the rainfall intensity in freeway network operating efficiency effect is positive correlation.
