南京市快速內(nèi)環(huán)路指路系統(tǒng)改造應(yīng)用研究
鄒禮泉1 劉干2
摘要:指路系統(tǒng)是溝通人、車、路的紐帶,但目前存在快速路附屬設(shè)施的指路系統(tǒng)不完善和更新相對(duì)滯后等問(wèn)題,嚴(yán)重制約了城市整體路網(wǎng)功能的發(fā)揮。特別是老城區(qū)快速路通常是在原有的道路基礎(chǔ)上經(jīng)過(guò)長(zhǎng)周期、分段式改擴(kuò)建形成,對(duì)指路系統(tǒng)的設(shè)計(jì)設(shè)置很難兼顧周邊路網(wǎng)的整體科學(xué)合理布局考慮,缺乏連貫性、系統(tǒng)性,直接影響快速路的通行效率和秩序。本文以南京市快速內(nèi)環(huán)路指路系統(tǒng)改造為研究對(duì)象,通過(guò)分析南京快速內(nèi)環(huán)線指路系統(tǒng)存在的問(wèn)題,通過(guò)明確道路管理名稱、規(guī)范指引路徑原則、創(chuàng)新光學(xué)模式等措施,提出指路系統(tǒng)改造的方案。本研究旨在為城市快速路指路系統(tǒng)改造和后期快速路指路系統(tǒng)整體設(shè)計(jì)提供參考。

Research of Rebuilding & Application for Traffic Guiding System of Nanjing Inner Ring Expressway
Zou Liquan1 , Liu Gan2
Abstract: Traffic Guiding Systems are links among human, vehicles and roadways. At mean time, the traffic guiding system of expressway is not in good condition and becomes relative lagging which restrict the functional development of whole city road network. The replacement of expressway for old districts is normally reconstructed on the basis of existing road system over a long period of time and section by section. The design & setting up of traffic guiding system are lacking integral consideration on adjacent road network which directly affect the efficiency and order of expressway. This paper analyses existing problems of Nanjing inner ring expressway and proposes plan for replacement of traffic guiding system by defining road management name, specifying road guiding principle and innovating optical mode. This research will provide experience for similar projects.
Key words:replacement of expressway, traffic guiding system, self-luminous, functional improvement

南京市快速內(nèi)環(huán)路(以下稱快速內(nèi)環(huán))始建于上世紀(jì)90年代,規(guī)劃的“井”字形快速內(nèi)環(huán)路,位于長(zhǎng)江以南、繞城公路(二環(huán)快速路)以內(nèi)區(qū)域,以新莊立交、古平崗立交、賽虹橋立交、雙橋門立交4個(gè)互通立交為頂點(diǎn),環(huán)繞南京老城主要區(qū)域,并放射狀連接繞城公路。2014年 “井”字形環(huán)線已基本成形,8條放射連接線(2條未建成)中,5條連接繞城公路,3條連接長(zhǎng)江大橋、揚(yáng)子江隧道(2015年通車)、南京長(zhǎng)江隧道等3條過(guò)江通道??焖賰?nèi)環(huán)線主線雙向6車道,設(shè)計(jì)車速60km/h(南線高架80km/h)。(圖1)
