遠程控製實現“可變綠波”,解決交通擁堵等問題



“綠波帶”串聯起南京七成信號燈控製路口

  “綠波帶”串聯起南京七成信號燈控製路口

  

  截止到今年10月,南京市機動車保有量已達253.53萬輛、駕駛人達334.26萬人,在這種機動車及駕駛人快速增長的大背景下,南京交通擁堵延時指數卻從2014年一季度的3.17下降到2017年三季度的1.79,這其中就有信號燈聯網的功勞。隨著南京市797個交通信號路口完成遠程聯網,南京交警坐在指揮中心就可以根據實際需要,對各路口的交通信號進行遠程調控,從而解決救援保障、交通擁堵等問題。


  南京市區已設置156條車流“綠波帶”


  為了緩解城市交通壓力,截至今年10月,南京交警共在市區設置建設了156條車流“綠波帶”,同時利用“交通信號遠程控製”對綠波信號進行實時動態調整等方式來提高道路的交通效率。


  目前156條“綠波帶”中包含137條全天“綠波帶”和19條潮汐式“綠波帶”。全市1509個信號燈控路口中,有1074個路口的交通信號燈被“綠波帶”串聯成網,“綠波帶”基本形成了連片成網的發展結構。其中鼓樓區共設置了41條綠波帶,位列全市第一;建鄴區設置了34條綠波帶,位居第二;玄武區27條綠波帶,位列第三。


  南京交警在19條道路設置了“潮汐式綠波帶”,如每天上午北京東路、龍蟠路、中山東路、瑞金路、常府街這幾條道路東向西的進城方向和漢中門大街、水西門大街、集慶門大街、黑龍江路的西向東進城方向。到了下午上述道路的反向出城方向則會形成綠波車流,大大節省了車流等紅燈的時間。


  遠程控製實現實時“可變綠波”


  “綠波帶”的關鍵就是根據預計車流速度測算出來的綠燈時間,一旦實際車速與預計車速存在較大差異時綠波帶不但發揮不了作用,很可能還會變成“紅波帶”。傳統“綠波帶”的設置和調整往往需要好幾天的時間。


  而“交通信號遠程”係統投入使用後,當民警發現道路條件發生較大變化、“綠波效應”減弱後,則可以立即根據實時路況的反饋,在指揮中心就可以即時重新調整信號參數,進而對“綠波帶”重新匹配。


  實時對接附近公交,實行綠波放行


  797個路口交通信號進行遠程調控升級後,還能實時與附近公交車輛進行GPS數據對接,在滿足社會車輛通行需求的基礎上,構建地麵公交優先的信號控製策略,對公交車輛實行綠波放行。在公交優先控製的通行線路上,公交車輛的平均車速提高了15%,停車次數降低了30%,大大提高了公共交通的服務水平,這也吸引市民更多地采用公交出行,減少私家車的使用,從而緩解南京市道路擁堵狀況。


  據統計,交通信號遠程聯網平臺投入使用以來,南京交警月均遠程控製信號燈達900餘次,大大提高了全市道路的通行效率。得益於“綠波帶”的大範圍建設,市民駕車出行5分鐘之內就能進入“綠波帶”。在南京市這五年來機動車猛增近一倍的情況下,中山東路、北京東路、漢中路等設置綠波帶的道路平均車速仍然提高了15%,江東中路(漢中門大街至江山大街段)北向南方向通行效率甚至提高了53%。

  臨時“綠波帶”,關鍵時刻救人命


  今年10月21日11時,南京市六合區市民王先生的女兒突發腸套結,須立即送往兒童醫院救治。而王先生發現通往江南的道路非常擁堵,於是報警求助。南京交警指揮中心立即調用離報警人最近的一輛警車與王先生會合,沿途交警九大隊、五大隊警力對車輛進行分流。同時,指揮中心民警根據視頻監控追蹤救援警車,遠程為該車設置了一條臨時“綠波帶”,讓救援警車一路綠燈,當車輛通過揚子江隧道進入主城區後僅用15分鐘就將患者送到廣州路上的兒童醫院。由於送醫及時,孩子得到了有效的治療。


  □ 名詞釋義


  “綠波帶”:在特定的交通線路上,信號燈根據車輛的平均行駛速度測算出車流到達下一路口時間,在車流到達下一路口時繼續保持綠燈通行,從而提高車流的平均車速。

Place




We took time, it is a flower. A pen with the fibrillation, mountain high, water mountain farther away, missing is long. When I look back deeply buried for thousands of years in mind, Jiangnan red, hope of reunion among friends, all the way through the cold thin, is no longer the initial appearance. A smile, conceal the past few desolate. The beautiful scenery of the hourglass, a little bit of butterfly wings generally weak warm beach that a piece of hot mood. Dim winding with heart king, fragrance, such a long way to go, there is no one to the landscape seen through. When Oracle still years heart Geng croon, only those with heart, shadow Dzodzo, flowing with tenderness, as I touch the warm winter sun.

The obsession of blue and white places, Qing Huan Ning Shang, on eyes, how much scenery? How many inexplicable sadness; read the journey, how far? On the way home. And students spend injury, how many? Several lines, a few left, and ultimately into each other. How many sketch? In the language of light to sketch painting, into the heart of clouds. Don't, Yanbo Hao wan. Read, a process, a process of water. The volume also vicissitudes, Shu and the vicissitudes of life. To read the angle, the heart is boundless, career, forget the. Be fatigued with the journey of dust Road, perhaps, you are my strongest eyes, after wandering Jingyue, wind, watching the best rain, then read.

Twist a static guard, mind buried in the years of Qing. Broken pen is wind, origami for cloud, covered with thick cloud, let the heart without a word. I to you leave the landscape, the smile for strings, just behind the dance to sing, play the game to meet the appearance, about a case of glass. Take a flower posture, stepping on the valve of the heart road, inclined eyes warm greetings, a way with words of mood, walk into a world of shallow reading, in rolls of the moon in wind, a look of a safe.

Pile of a word when, in a plain and keep flowers, Wang Li, the old quarter lights, hot a heart light, drinking a bottle of Su Mo light pen. The word dream faint, clean water Qing Yang sway in a moist, smooth circulation, tearing the Jiangfeng Yuhuo worry sleep, polyester net years past Yan dye from the war. A drop of love, nestled into the dust days, open leaning against the railing heart sand, creeping in the warmth of heart, let the shallow ripple interpretation of the memory thin graceful charm. Let Miss Ao had thoughts Neon Flying clouds. Push ground fragrant, curtain roll westerly, using ink, Lianxiang, blow to a pillow dream.

Crayons heart draw, draw the dream. In a past heart size, pull a hand care, bathing in the fleeting heart volume, occasionally pick a color memory, dip in with static Shou, straighten out the dust blown heart silk chaos, listen to the text a stampede days finely sound, see Chapter water toilet, see a smile ripples. Acacia, not full of sadness, also have to rain smile! The moment the memory falling, I never suspected heart feelings for you. Even if the fall, I will fall in your dust, into a dust, quietly accompany in your side.

Hot summer season away and beware of text, which is by the light is back to a season of desolation. The remainder of the wandering life may take away a lot of things, such as pens, according to the book, the heart clear water, ink makeup appearance, only do not go with you in my heart is stationed, a thick don't open eyes.

Go to, read broken. Chasing a dream extension ink, a moment heart white an warm, you are my way an attractive scenery line, when the crack wisps of light penetration and wandering, name your everlasting wrote, road, suddenly bright and clear up. Warm, eclosion intentionally ditch rippling, waving meet graceful posture, intoxicated with and read a dream!

Jingan red




Read the night, Lin Yi Cheng landscape, draw a heart, take a dream years fragrance, a skirt past glass, put a graceful stretch, sketch drawing water shallow, shallow Red Book Mou Huan, Jingan.

Read the evening, I stood in the Acacia high on the balcony, facing the memory came rippling. A winding lonely, flat Zeze seasonal shallow pan, cotton stretch in the heart at the end of the drain. I know, your heart I have, my heart is your footprint, a skyline across the incense every warm two stab the heart, with a thin Tang legacy, charged with "spring water is also falling, immeasurably vast difference." The sad fragrance.

Lin Cheng landscape, draw a heart, heart silently closed cone, attachment, let the past flowing, and sigh blown by wind in the essays, far discount pillow LAN, walked all the way, all the way twist. Pick up the word of the Xinmei skeptical, flute, in the lotus traversing palm wandering, you Ying Mo with camphor warm attitude away from me. Ever review? Loud amidst the blurred the ink. Some read, some books have, in the years of pain in the format, may not be able to really dry, remove. Perhaps, in some old once grand corner, it will continue to pass through dust, walked back, standing in front of the soul and heart, watching each other in silence.

Heart wind blowing, a skirt past glass, put a graceful stretch, joined with the cosmetics, water according to the study, the curl of smoke in the text, the dream look more and more long. Miss, in turn appears calm as water is flowing down the tears, gently open, open the lonely flower face. Life places hidden fragrance, I stood as a day outside the coveted rye, flow into the red line in the book far and wide, eyes reflected the paper window, running into the evening that dreary muddy horse sad sad. The open read, touched the geranium Strictipes impervious face, Rong Sichuan Wenling never abandon the oath. A pale aroma nomadic love songs, after writing, words do not shoot, linger. The skyline, depressed heart Yan, in the cloud messy Weiyang, long time don't open chanting gallop the vicissitudes of life.

Love, really can bury? I'm in a meeting of the past is buried, again and again hurt deeper, the deeper pain. Heart, Yanbo Hao Miao; sometimes feel it is so narrow, small to you alone.

A dream tree flowers, a curtain dust away, like a flower, and let the night warm. I know, you are a time to pick the very light, just wandering in the pen, not in the water Xinmei cloud slightly. A pen shallow warm winter read a word, static heart leisurely, who met with the fragrance of writing? Filter out past the sentimental, wind yarn made by very full life. Maybe, you are my only one hairpin read cloud butterfly, by my final thoughts. Sometime over the word, and my heart in the youth were, gently tingling, let a read to send, return to the soul place.
