摘要
为了揭示高速公路合流区加速车道上车辆的运行规律 ,利用摄像机等观测仪器对中国许多省市高速公路合流区匝道车辆的汇入特征数据进行了大量调查。在对大量调查数据进行分析处理的基础上运用微分法建立了匝道车辆的汇入模型和行驶距离模型。该模型不但解释了调查结果 ,而且对高速公路规划设计。
In order to work out merging regulation of ramp vehicles,video tape recorder and other observation device were used to investigate the merging characteristics data in many provinces and cities of China.Based on a lot of analysis and disposal for investigated characteristics data of freeway merging areas,the merging model and the travel distance model of ramp vehicles on acceleration lane without merging into is set up with differential method.This model explains the investigated results and it is significant to guide the engineering practice in the planning,design,management and control of freeway.
