北京運輸系統(tǒng)-畢業(yè)論文外文翻譯

1、附件 1：外文資料翻譯譯文北京運輸系統(tǒng)摘要：運輸系統(tǒng)提供了與城市郊區(qū)顯著不同的服務(wù)，這通常會導(dǎo)致有關(guān)用戶選擇交通方式的不同假設(shè)。本文所提到的仿真模型，提出了評估影響運輸服務(wù)的政策。運輸方式被認為是公共交通工具，包括輕型軌道交通（輕軌）和公共汽車，加上私人轎車。在三步旅行者行為仿真模型中，使用了廣義運輸成本的概念。它提出各類交通以及對居民的出行選擇和郊區(qū)住宅社區(qū)形態(tài)量化的建議，并使用了源自于中國北京一個典型走廊的數(shù)據(jù)。仿真結(jié)果表明：票價降低，增加公共交通的綜合能力，以及對私家車的懲罰是很有必要的，以此來提高系統(tǒng)效率和郊區(qū)的吸引力，特別是對那些低收入的人；沒有公路定價，將鼓勵中等收入居民轉(zhuǎn)向私人轎

2、車，同時 , 高收入者可能因為道路擁擠離開郊區(qū)；然而公共交通的改善可以吸引更多短距離和中距離的旅客，但轎車用戶對于旅行距離并不敏感。關(guān)鍵詞 ：廣義成本，公共交通，擁擠定價，運輸服務(wù)，北京從上世紀 90 年代，中國大中城市已經(jīng)歷郊區(qū)化，而且這些城市的空間結(jié)構(gòu)逐步形成，在很大程度上依賴于交通運輸?shù)倪M步。由于人口爆炸和改造中心城市，許多郊區(qū)城鎮(zhèn)發(fā)展為住宅區(qū)，這些新發(fā)展城鎮(zhèn)的大部分居民受雇于中心城市或附近的工業(yè)區(qū)。例如， 80%多回龍關(guān)郊區(qū)社區(qū)的居民在北京或發(fā)達地區(qū)中心城市工作，幾乎有一半的北京社區(qū)居民受雇于朝陽區(qū)中央商務(wù)區(qū)。這些領(lǐng)域在交通系統(tǒng)規(guī)劃與提供經(jīng)營效率方面對交通政策制定者和城市規(guī)劃設(shè)計師提出

3、了新的挑戰(zhàn)。在許多情況下，邊沿城鎮(zhèn)通過高速公路和城市軌道連接中心城市或工業(yè)園區(qū)。相比傳統(tǒng)的城市， 郊區(qū)展覽更穩(wěn)定的運輸使用模式， 更加依賴公共交通， 私人汽車，較少使用機動模式（自行車，步行）。工作距離比任何單一因素對人們的交通方式的影響都大。 這樣的特點，可以深刻影響的人口郊區(qū)化， 并限制一些人移民到郊區(qū)。本文利用西北地區(qū)的北京作為一個測試案例，分析了運輸服務(wù)的政策，主要是費用和服務(wù)質(zhì)量，將影響整體運輸系統(tǒng)與城市空間結(jié)構(gòu)。本文的組織如下：第二節(jié)簡要回顧最近一些有關(guān)運輸方式選擇的文獻，并與海城市海城走廊案件，特別是中國的現(xiàn)狀進行比較。第三部分討論廣義運輸成本的概念，并建立了新的概念，包括利用廣

4、義成本和轉(zhuǎn)移成本預(yù)算的障礙。第四節(jié)在公共運輸和駕駛之間介紹旅客運輸方式選擇行為仿真模型，然后轉(zhuǎn)向注意中國經(jīng)驗運輸服務(wù)政策與海城市海城出行方式選擇。在第五節(jié)中，特別提到的情況是，利用北京的輕軌和高速公路，西北地區(qū)迅速郊區(qū)化。在第六節(jié)中，得出主要研究結(jié)果和政策啟示。大量的研究機構(gòu)在研究運輸方式和個體出行方式的選擇。一般來說，有三種常見的方法來確定這個問題。第一部分著重研究影響選擇決策的每個模式的特點，所采用的實證研究狀況用于改變結(jié)果，研究人與旅游目的等。例如， travel-to-work 行為在阿克拉 （加納）主要由知覺服務(wù)品質(zhì)、 商業(yè)通勤車以及員工的個人情況決定，而不是通過訪問，等待時間或車載

5、。在英國，為了走親訪友而決定行程，經(jīng)濟因素在很大程度上解釋模式的選擇，使用私人交通工具時定性的理由往往是次要的（科恩、哈里斯， 1998）。約翰松等使用瑞典上班者的圖片案例表明了靈活性和舒適性這兩個感覺影響個人的選擇模式。根據(jù)在法蘭克福，德國的實驗領(lǐng)域研究和統(tǒng)計分析，認為有四類人。一類人很少重視金錢和時間因素，第二種人非常重視金錢但很不重視時間，第三種人都重視，第四種人很少重視金錢但很重視時間。林坦庫等人選自來自 1998 年的數(shù)據(jù)，即荷蘭國家旅游調(diào)查組確認空間配置，土地利用和交通基礎(chǔ)設(shè)施，對長途旅行模式比如通勤，商務(wù)和休閑旅行具有重大影響。廣義運輸成本的概念經(jīng)常用于評估和解釋的旅游行為。廣義

6、旅行成本包括旅行時間，超過時間，金錢成本，停車收費，和一些令人忽視的小費。然而，這一概念在不同的文獻因為不同的研究目的是不同的。例如，廣義騎自行車費用如下：旅行時間，物理需要，舒適，交通安全，自行車被盜的風(fēng)險，停放自行車的費用以及維護費用，個人安全。貨幣化的廣義概念通常是將旅行時間轉(zhuǎn)換成貨幣費用，增加的費用，收取的費用，在這項研究中，模擬通勤出行行為，三個運輸關(guān)于概念費用是相通的。第一個可以被定義為預(yù)算障礙，包括經(jīng)營費用，養(yǎng)路費以及停車場收費。第二個是貨幣化的廣義成本和時間成本，包括經(jīng)營費用，以及停車費用。用戶被假定為盡量減少個人的貨幣化成本，把自己的出行方有別于旅行時間和費用成本。廣義貨幣化

7、成本的公共交通是計算訪問到火車站的時間，等候時間，這是計算的基礎(chǔ)上的進展，等車時間，以及票價。貨幣化費用包括旅行時間，收費，汽車運行成本和在工作地方的停車場收費。第三個概念是確定模式轉(zhuǎn)移成本即擁擠造成不適的成本。據(jù)推測，如果乘客在車輛已遠遠超過容量，新來的旅客會轉(zhuǎn)移到其他負擔得起的運輸方式。貫穿城市及鄉(xiāng)村的公路通常是不僅僅可以通私人轎車，也可以通公共汽車。介于以前的經(jīng)驗，道路定價可以大大提高用戶的剩余地區(qū)，公共交通的費用可以大大減少因長時間的旅行而造成的擁擠， 特別是，如果用戶很大程度上鐘情于公共交通。方案 2 表明高收入的旅客不得不放棄定期遷移到郊區(qū)的計劃，主要由于免費使用的情況下所造成的嚴

8、重擠塞。另一組是深深影響了中等收入的旅客，她他們從公共運輸方式換成了私家車駕駛。公共汽車票價降低和公交線路的增加使得許多中等收入居民轉(zhuǎn)移去坐公交車，同時小汽車用戶轉(zhuǎn)移到輕軌，特別是那些短距離旅行。此外，研究發(fā)現(xiàn)，一個綜合改善公共交通服務(wù)和一些私人汽車懲罰措施的政策，有利于提高系統(tǒng)效率和郊區(qū)社區(qū)的吸引力。這種綜合系統(tǒng)包括輕軌、公共汽車票價的降低，服務(wù)質(zhì)量的提高和公路通行費的征收。應(yīng)該指出，輕軌已旨在增加公交扶手使公共交通更吸引用戶，從而，減少道路擁擠。根據(jù)模擬結(jié)果，輕鐵及巴士票價減少以及客容量的增加，使這一模式對于那些中低收入旅行者更有吸引力。最后的結(jié)果是，越來越多的人移民到郊區(qū)，不論是低收入到

9、高收入階層。當然，公共交通服務(wù)的改善需要政府補貼，這也是一個世界性的現(xiàn)象。每個模式的經(jīng)濟旅行距離幾乎不受不同的運輸服務(wù)的政策影響。公共汽車是用于短距離的旅行，而中、長距離者喜歡輕鐵。反之，小汽車用戶則是無所謂。結(jié)果表明，這些低收入公民因現(xiàn)有運輸服務(wù)的政策限制遷移到郊區(qū)的經(jīng)濟房屋，包括相對高收費的公共交通和公路，以及有限的輕軌和公交線路。當然，所有運輸模式對于在家工作的人在一定程度上都有影響。城市交通在整個世界中都是是政府政策的一個主要領(lǐng)域。運輸政策也會影響城市形態(tài)，尤其是郊區(qū)化。 在北京，許多經(jīng)濟公寓是專為那些低收入居民建造準備的。在重大問題的決策之前有兩個主要的問題。首先，從過去的經(jīng)驗，大量

10、在郊區(qū)社區(qū)中的永久居民都是中等或更高收入的人。而且很多的業(yè)主仍然居住在城市中心，郊區(qū)房子只用來去度假。此外，居民不斷投訴交通擁堵和相對高的收費公路，特別是在繁忙時間。本研究的模擬結(jié)果解釋了這些現(xiàn)象并嘗試給出了相應(yīng)的政策含義。附件 2：外文原文Transport systemAbstractTransport systems offer substantially different services in city-suburb areas; this usually leads to different assumptions aboutuserbehaviorin transport mo

15、service, BeijingFrom the middle of 1990s, metropolitans in China havebeen experiencing suburbanization, and the spatialstructures of these cities are shaped, in large measure, bythe advances of transportation. Many suburban towns weredevelopment only for residential areas because of thepopulation ex

Forexample, more than 80% residents of Huilongguansuburban community in Beijing have jobs in central cityor developedCBD areas. And almost halfof the

Theseareaspresentnew challengesfor transport policy makersand urban planning designers to plan and operate efficienttransportation systems.In many cases the edge towns are connected to the centralcity or industrial parks by hi

Compared to traditional urban areas, the suburbantowns exhibit more stable transport mode use, morereliance on public transport and private automobile, lessuse of non-motorized modes (bicycle, walking). Home towork distances have a stronger bearing on people stransp

Such characteristics can deeply influence thepopulation suburbanization, and restrict some people fromimmigrating to the suburb.This paper analyses how the transport service policy,mainly fare and service quality, will impact the overalltransport system perfor

For trips made to visitfriends and relatives in Britain, the economic reasonslargely explain mode choice, and qualitative reasons forusing private transport are often secondary (Cohen andHarris, 1998).

One class allocates a lowimportance to both monetary and time considerations, thesecond allocates high importance to money and lowimportance to time, the third allocates high importance toboth, and the fourth allocates a low importance to moneyand a high importance to time (Davidov,

The generalisedcosts of travel include the travel time, excess time, money cost,parking charge, and the discomfort and lesser connivance. However, this concept is diverse ind

30、ifferent literatures for varying research purposes. Forexample, the generalised costs of cycling are the following:travel time, physical needs, comfort, traffic safety, risk ofbicycle theft, costs of parking bicycles and maintenancecosts,personal security. Andthe concept of monetized generalised cos

31、t is usuallycalculated by converting travel time into monetary cost,and adding the cost of the fare chargedIn this study, for simulating the commuter travelbehaviour,s three transport costs related concepts areadopted in order. The first can be defined as budget barrier,including the fare or toll ch

Users are assumed to minimize individualmonetized generalized trip cost and dividethemselvesamong the travel modes that are differentiated in tr

33、aveltime and fare cost. The monetized generalized costs ofpublic transport is computed as a function of the accesstime to the station, the waiting time which is calculatedbased on the line s headway, in-vehicle travel time, and thefare. The monetized generalized cost of driving includestravel time,

34、toll, car operation cost and parking charge inwork place. The third concept is identified as mode shiftcost which means discomfort cost caused by congestion. Itis assumed that if the passengers in vehicle have farexceeded the capacity, the new coming passenger will shiftto other affordable transport

35、 mode.The city-suburb highway is usually used not only byprivate auto, but the bus. Usingthe previous experience，road pricing can greatly increase users surplus in the areawhere the cost of public transport can be significantlyreduced by decreasing congestion becauseof the longtravel distances invol

36、ved, Particularly, if a substantialportion of users are captive to public transport. The results of scenario 2 show that more highincome travelers have to abandon the plan of migrating tosuburb mainly owing to the serious congestion on thecondition of free use. Another deeply influenced group ismedi

37、um income travelers who shift from public transportmodes to car driving.Bus fare reduction and bus lines increase make manymedium income residents shift tobustransport, meanwhilethe car users shift to light rail, particularly those who travelfor short distances. Furthermore, the research finds that

38、anintegrated policy of improved public transport service andsome private car disincentives is beneficial to improvesystem efficiency andsuburbcommunityattractiveness.The integration consists of light rail and bus fare reduction,service quality improvement and highway toll imposition.It should be poi

39、nted out that light rail has been designed toincrease transit rider ship by making public transport moreattractive to users and, thus, to reduce road congestion.According to the simulation result, the light rail and busfare reduction and capacity increase makes this mode moreattractive to those low

40、and medium income travelers whoare captive to bus mode before. The final outcome is thatmore people can migrant to the suburb, from low to highincome classes. Of course, the public transport serviceimprovement requires government subsidization, which isa worldwide phenomenon.The economic travel distance of each mode is almost notaffectedby different transport service policies. Bus is usedmore by short distance travele
