Reserved Design Analysis of Additional Interchange on Expressway

从交通量持续增长和交通建设可持续发展的角度出发,互通式立交的建设时应充分考虑主要道路扩建的需求,做好加宽改造的预留条件。文中结合工程实例,分析总结了国内公路互通式立交中主要道路的改扩建预留方案存在的问题,提出了关键的解决措施。

From the perspective of sustained growth of traffic volume and sustainable development of traffic construction, the construction of interchanges should fully consider the needs of the expansion of major roads, and make the reserved conditions for widening the transformation.
