城市快速路的匝道合流区主线不同于普通路段主线，具有车速慢，扰动和变道频繁，随意挤占车道的特点，为了避免匝道合流区交通过于拥堵，车道的空间如何布置成为当前国内外研究的热点。文中以匝道合流区主线线圈实测的数据为基础，研究了匝道合流区主线车道宽度设置对交通的影响，分析了车道宽度设置影响的因素，建立了车道宽度对交通流通行能力影响的回归模型。模型结果显示，车道宽度的不同会影响到匝道合流区主线车速和通行能力。

Because of the slow speed ,frequent disturbance ,lane changing behavior and freely squeezing characteristics ,the on‐ramp merging area is different from the main line .In order to alleviate traffic jams in ramp merging area ,lane space layout becomes the key point of recent domestic and foreign re‐search .Based on coil measured data of ramp merging area ,the influences of width settings ramp mer‐ging area lane on the traffic were researched in this paper .On the basis of the scholars’ studies at home and abroad ,the factors of influencing the lane width settings were analyzed .The regression model about the influence of the lane width settings on traffic capacity was summarized ,and the model results showed that the difference of lane width would affect the relationship between speed and capac‐ity in ramp merging area .
