【摘要】:區(qū)域道路穿越城市的負外部性顯著,傳統(tǒng)的"修復型"應(yīng)對方案存在道路建設(shè)總量和城市交通成本大幅增加的弊端。本文基于交通流分解和城市功能組團化布局提出了"分流型"交通方案,并通過模型計算證明"分流型"交通方案具有明顯的成本優(yōu)勢。最終得出如下結(jié)論:(1)分流型交通方案可以實現(xiàn)控制交通總成本和提高交通運行效率的雙重效益;(2)城市功能的組團化布局是分流型方案得以實施的關(guān)鍵;(3)區(qū)域道路在規(guī)劃建設(shè)時應(yīng)充分考慮地方城鎮(zhèn)的發(fā)展訴求。在應(yīng)對交通基礎(chǔ)設(shè)施快速發(fā)展導致的城市用地破碎問題方面,本研究具有一定的借鑒意義。
[Abstract]:The negative externalities of regional roads passing through cities are significant. The traditional "repair" response scheme has the drawbacks of increasing the total amount of road construction and the cost of urban transportation. Based on the decomposition of traffic flow and the urban function group layout, this paper puts forward the "shunt" traffic scheme. It is proved by model calculation that the "shunt" traffic scheme has obvious cost advantage. Finally, the conclusion is drawn as follows: the shunt traffic scheme can realize the dual benefit of controlling the total transportation cost and improving the traffic operation efficiency, and finally comes to the conclusion that the shunt traffic scheme can achieve the dual benefit of controlling the total traffic cost and improving the traffic efficiency. The cluster layout of the urban function is the key to the implementation of the distributary scheme. In planning and construction of the regional roads, the development demands of the local towns should be fully taken into account, and the problem of urban land fragmentation caused by the rapid development of the traffic infrastructure should be dealt with. This study has certain reference significance.
