交通本科毕设外文翻译

1、.1工程大学土木工程学院毕业设计外文资料翻译专 业学 生指导教师 工程大学土木工程学院2021年6月4号未来个人运输在世界大城市中的开展Schafer, Jacoby,Heywoodand Waitz2021研究认为一个人平均每天花大约70分钟的时间使用交通工具。这个时间预算在过去各个国家中是相对稳定的。所以，富有的人开场倾向于跑的更快，跑的更远。而在不久的将来，全世界将会全面提高机动车的机动性。例如：Schafer and Victor (2000)推测，预计到2050年世界公民行驶的整体平均路程将比欧洲在1990年跑的整体平均路程多。从2000年到2050年，美国的平均机动性将提高2.6倍

2、，到达每年58000千米。Schafer and Victor (2000)还预估，到2050年印度的平均机动性将增加到每年6000千米，到达了欧洲1970年早期的水平。总的来说，人们在2000年能行驶230亿公里，到了2050年，有望增加到1050亿公里。与此同时，城市人口正持续增大。根据World Bank2002研究，拥有1000多万居民的大城市的数量有望在下一代翻倍。随着城市的扩大和富裕，车辆所有制以及其使用会快速增加，相反，这将影响车辆的行速，加大道路拥挤和空气污染。上述趋势使得人们对大城市可持续开展交通展开了广泛地讨论。从广义上讲，城市交通的可持续运动涉及到可操作性以及通过公平高效

3、手段产生的财富问题，同时还要维护身体安康，将自然资源消耗和放射性污染减到最低。通常，广泛使用公共交通和快速轨道交通是可行的。例如：像东京，这样的大城市，它们在私人车流行前就投资建立公共交通，以提供广泛的，优质的公共交通系统。在这些城市，直到快速轨道交通的建立，公交远行还一直处于高水平阶段。然而，个人交通工具已成为现代城市生活的一局部。不管是作为独有的、分享的还是用于飞行的交通工具，它们都给个人和社会带来了很大的便利。因此，Kennedy et al. (2005)指出，对于城市的可持续开展来说，为新一代可持续个人交通工具做规划是至关重要的。同时技术创新和工业生态学观念的应用，让可持续个人交通工

4、具成为了可能。另外，许多应用智能型运输系统将充分影响未来城市交通运输。这些应用程序包括需求管理需求感应公共交通、汽车共乘共享、通路管制以及道路使用要求、旅行方案系统/实时旅游者信息、公共交通信号优先系统。为了研究大城市中个人交通运输目前及将来的状况，本文选取了世界15大都市，根据地理位置划分可如下所示：北美洲：芝加哥、纽约欧洲：伦敦、莫斯科、巴黎中美洲、南美洲：布宜诺斯艾利斯阿根廷首都、墨西哥城、里约热卢、圣保罗印度：班加罗尔、加尔各答、新德里、孟买中国：、 对于各个大城市来说，一系列影响未来交通的关键指标是已检定的。主要包括人口和财富、私人电动客运车辆、公共交通模式操作、运具选择、旅行速度模

5、式、交通事故。以人口和财富为列，因为人口的大小以及人群的富有程度起到至关重要的作用，因此对选定大城市的人口预期增长和大城市所在国的人均财富预期增长作出相应比较。结果显示，从2005年到2025年预计出现人口增长最高比例超过预期30%的地区有班加罗尔、加尔各答、新德里、孟买和，其次为适度增加12%-18%的芝加哥、墨西哥城、里约热卢和圣保罗，增长最慢的低于12%主要有布宜诺斯艾利斯、伦敦、莫斯科、纽约和巴黎。总体上说，人口增长最快的现象将出现在印度和中国。而从2021年到2021年，预计收入增长最快的是中国，接着是印度、俄罗斯、墨西哥、巴西、英国、阿根廷、法国和美国。然后，对选定大城市的方案策略

6、进展分析，这些大城市主要有：纽约、伦敦、圣保罗、孟买和。同时，目前的结论不需完整描述一个策略。例如：在国家、地区和地方上，城市交通规划会涉及很多政府的构造，并且每个层次都有它自己的策略。所以，策略分析的主要目的是突出已定大城市在未来10到20年的主要目标、实施重点以及措施方案。其关注点是方案出行方式即该策略如何预想私人车辆、公共车辆以及非机动车辆在未来的作用。以纽约为列，区域交通规划的目标是从2030年开场，满足城市和地区的交通需求，并提高行驶速度。这个方案策略包括改善交通网络，通过更好的道路管理和拥挤定价来减少交通堵塞。具体措施如下：1提高关键拥堵路线的承载力2提供新通勤火车进入曼哈顿3增加

7、到稠密地区的交通4改善、增加公共汽车效劳5改善当地通勤火车的效劳。另外，纽约近期推出了自己的战略方案。主要目标包括：例如城市交通事故减少50%；实施快速公交线路措施，以提高全市汽车的行速；到2021 年使自行车通行翻一倍；启动全市停车政策来管理空间，以此减少巡航和拥堵；采用完整街道设计模版为重建工程；提供更好的街道面等。最后，对选定城市的未来运输方式进展了讨论。主要包括个人车辆人均所有权、在城市部个人车辆行驶的人均距离、用于通勤的个人车辆行驶的人均距离、用于休闲旅游的个人车辆行驶的人均距离、道路死亡人均数量、新的机动网络。基于上述研究，我们预测到2025年各大城市都或多或少会有些改变，主要改变

8、有个人交通工具的所有权、由个人交通工具在核心决定的人均距离、道路死亡人均数量等。这预测主要包括以下几方面：个人车辆所有权大幅增加的现象将出现在印度的四大城市和在任何大城市中，使用核个人交通工具的数量将不会增加预计用于通勤的个人交通工具的使用也将不会增加用于休闲旅行的个人交通工具数量将增加并且交通事故增长最快的，这种现象主要出现在，其次是印度的四大城市，里约热卢和圣保罗总的来说，在未来的15年，可以预见到在选定大城市的各个地方不会出现大幅度降低对个人交通工具依赖的现象。相反，我们预计在印度、中国、巴西的大城市中，个人交通工具的作用将会不断上升。上述趋势的出现是由于我们视不同的交通运输方式为独立唯

9、一的选择。然而，越来越多的实施和新机动网络正处于使用中，即综合网络提供多，高技术，门到门的交通运输方式选择。虽然，这些网络有望减少人们对个人交通运输的依赖度，但这种特性的大小和影响仍有待确定。The Future of Personal Transportation inMegacities of The WorldOn average, a person spends about 70 minutes per day traveling (Schafer, Jacoby,Heywood, and Waitz, 2021). This time budget is relatively con

Fore*ample, Schafer and Victor (2000) projected that by 2050 the average citizen of theworld willtravel

11、(by all modes) as much overall distance as the average WesternEuropean did in 1990.From 2000 to 2050, the mobility of the average American will increase by a factor of 2.6, to58,000 km/year. Schafer and Victor (2000) forecast that the average Indian will increase his/hertravel to 6,000 km/year by 20

12、50, parable to the level of West Europeans in the early 1970s.In total, in 2000, people traveled 23 billion km, and by 2050 that figure is e*pected to grow to105 billion km (Schafer and Victor, 2000).At the same time, urban population continues to e*pand, and the number of megacitiescities with over

As cities grow and bee richer, vehicle ownership and use tend to increase rapidly.This, in turn, has an influence on travel speed, congestion, and air pollution.The above trends have resulted in wide discussion about

Through technical innovation and the application of concepts of industrial ecology,there are several possible candidates for the sustainable personal vehicles of the future (Kennedy et al., 2005).In addition, it is likely that many applications of intelligent transportation systems wil

For e*ample, the urban transportation plans of large metropolitan areas typicallyinvolve many government structures at national, regional, and local levels (see e.g., Urban Age,2021), and each level can have

The specific initiatives include thefollowing: (1) to increase the capacity on key congested routes, (2) to provide new muter rail access to Manhattan, (3) to e*pand transit access to underserved areas,

30、(4) to improve ande*pand bus service, and (5) to improve local muter rail service.In addition, New York City has recently introduced its own strategic plan (NYCDOT,2021). Its major goals include, for e*ample cutting city traffic fatalities by 50% from the 2007levels, implementing bus rapid transit l
