| 摘 要： | 主要阐述匝道的计算车速对变速车道长度影响较大,而不是和变速车道长度无关;目前规范中规定的变速车道长度比较适合V1和V2相差小时,如V1和V2相差较大时,上述的变速车道长度则略显偏小。

| Abstract: | This paper states that the ramp calculation speed can affect the length of speed change lane.The length in the criterion is suitable for that the difference between the speed of V1 and V2 is small.If the difference is big the length seems to be small. |
