城市道路改造中交叉口小半径路缘石研究与应用

摘要:

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,其改造效果对最终改造效果有重要影响。交叉口小半径改造是交叉口改造的重要手段之一。本文基于车辆特性及驾驶习惯,对交叉口小半径参数进行了计算,得出了通行大、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改造为抓手,对交叉口的品质进行了全方面的提升。最后通过改造前后的参数对比,结果标明,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。

Abstract:

The demand of urban road quality improvement is becoming increasingly prominent. As an important control node in the road, the transformation effect of intersection has an important impact on the final transformation effect. Small radius reconstruction is one of the important means of intersection reconstruction. Based on the vehicle characteristics and driving habits, this paper calculates the small radius parameters of the intersection, and obtains the small radius value of the intersection under the condition of large and small cars. Then, combined with the road reconstruction project in Shenzhen, taking the reconstruction of Baogang road and Beidou road as an example, the quality of the intersection is improved in all aspects by taking the small radius reconstruction of the intersection as the starting point. Finally, through the comparison of the parameters before and after the transformation, the results show that the quality of slow traffic and vehicles at the two intersections after the transformation has been improved to a certain extent.
