摘要
通过速度图检验互通式立交匝道线形组合是否恰当,对匝道线形组合进行优化调整,使立交线形设计更加合理,符合汽车在立交区短时间内加速和减速的变化,保证行车安全。
Through the Velocity diagraw,the paper er. Then optimized in acceleration and regulation of it is carried out to make the alignment design more rational and conform to change deceleration of auto within short time in interchange region, guaranteeing the driving safety.
