城市道路改造中交叉口小半径路缘石研究与应用

Research and Application of Small Radius kerb of Intersection in Urban Road Reconstruction

城市道路品质改造的需求日益突出,交叉口作为道路中的重要控制性节点,其改造效果对整体改造效果有重要影响。交叉口小半径路缘石径改造是交叉口改造的重要手段之一。现基于车辆特性及驾驶习惯,对小半径路缘石参数进行计算,得出通行大、小车的情况下交叉口的小半径取值参数。然后结合深圳市道路改造项目,以宝岗路、北斗路两个交叉口改造为例,通过以交叉口小半径路缘石改造为抓手,对交叉口的品质进行全方面的提升。最后通过改造前后的参数对比,结果表明,改造后的两个交叉口慢行及车行品质都得到了一定的提升。

The demand of urban road quality improvement is becoming increasingly prominent.As an important control node in road,the reconstruction effect of intersection has an important impact on the overall reconstruction effect.The reconstruction of small radius kerb of intersection is one of the important means of intersection reconstruction.Based on the vehicle characteristics and driving habits,the parameters of small radius kerb are calculated to obtain the small radius value parameters of the intersections under the condition of passing large and small vehicles.Then,combined with the road reconstruction projects in Shenzhen,taking the reconstruction of two intersections of Baogang Road and Beidou Road as an example,the quality of intersection is improved in all aspects by taking the small radius kerb reconstruction of intersection as the starting point.Finally,through the comparison of the parameters before and after the reconstructions,the results show that the qualities of slow traffic and vehicles at the two intersections are improved to a certain extent after reconstruction.
