摘要
为了更好地维护城市中小学门口的交通安全,合理设置校门口减速带,根据校门口区域车型和车速的限制条件,分析了减速带基本形状和减速带分布原理;将汽车轮胎视为刚体,对车轮通过一个圆弧形减速带的状况进行几何分析和动力学分析,建立了圆弧模型和减速带分布模型。通过实例求解,给出了最优的减速带设置方案。该方案可为城市中小学校门口设置减速带提供参考。
In order to keep traffic safety near schools, we analyzed the shape of deceleration strip and theory of deceleration strip distribution under specific assumptions. Through the geometrical analysis and dynamic analysis of arc deceleration strip, we set up arc mathematical model and deceleration strip distribution model. Furthermore we provided the best distribution scheme according to an example, which can be a reference of setting deceleration strip near schools.
