Strategy and Case Analysis of Express Reconstruction of Urban Trunk Road

摘要:

城市主干路快速化改造不仅仅指将其改造成快速路，节点改造、提高行程车速也是重要的改造策略之一，两者适用条件和优缺点不同，相对而言，在城市中心区，节点改造策略适应性更强、更经济、更有可实施性，本文还提供了一些具体想法和案例分析，希望对解决快速化的此类问题能提供一些有益的参考。

Abstract:

The express reconstruction of urban trunk road is not only to reconstruct it into expressway and carries out the express reconstruction for the node to increase the travel speed, but also one of the important reconstruction strategies. The applicable conditions and advantages and disadvantages of the two are different. Taking the Dongguan Guantai Road (Hongfu Road - Dongguan Avenue) Express Reconstruction Project as an example, the detailed strategy and overall layout scheme of the node express reconstruction in the whole line are analyzed and introduced. The solution is proposed for some problems caused after the express reconstruction of the nodes. The conclusion is that relatively speaking in the central urban area, the adaptability of node express reconstruction strategy is stronger, more economic and more actionable.
