摘　　要：针对驾驶人因视距受限导致换道过程中压实线的问题,提出在道路虚线与实线间设置过渡标线的解决方案。基于车辆换道行为特征,定义过渡标线长度。通过驾驶模拟实验,分析车道宽度、车距及车速对过渡标线长度的影响。研究发现,车道宽度对过渡标线长度无显著影响,而车距和车速是影响过渡标线长度的关键变量,且过渡标线长度与车距呈负相关,与车速正相关。并在此基础上建立过渡标线长度关于车速和车距的线性回归模型。Aiming at the problem of pressing solid-line caused by driver′s limited visual range during lane-changing, the solution of setting transition marking between the dotted line and solid line was put forward. Based on the characteristics of lane-changing behavior of vehicles, the definition of transition marking length is given. Through driving simulation experiment, the influence factors of transition marking length are analyzed. It is found that vehicle distance and speed are the key variables affecting the transition marking length, while lane width has no significant. The length of transition marking is negatively correlated with vehicle distance and positively correlated with vehicle speed. On this basis, a linear regression model of transition marking length on vehicle speed and vehicle distance is established.
