序

我非常荣幸向大家介绍《城市绿道系统优化设计》这本书。中国绿道建设始于广东，2010年开始在全国范围内得以迅速推广。兴建绿道的城市从最初广东省珠三角地区9个城市到现在北京、河北、福建等地区的六十多个城市。绿道的建设倡导了“绿色出行，低碳生活”的新生活理念，不但极大地改善了居民的生活质量，还给市民提供了舒适便捷的出行方式。尽管绿道发展在国内取得了巨大的成绩，但在“连通、连续、隔离、可达、服务”等方面的设计却普遍存在人性化设计缺失的问题，完善以上五个方面设计是保证绿道设计高品质的关键因素。

I am very pleased to introduce the book,Urban Greenway System Optimum Design.The construction of greenways in China originated from Guangdong and expanded rapidly in China since 2010. The first parts of cities with greenways constructed in China were the nine cities in the Pearl River Delta, Guangdong Province. More greenways were later built in Beijing and more than 60 cities in other provinces including Hebei and Fujian. Greenway construction, when done well, has the potential to not only greatly improve residents' quality of life, but also to put into practice the new concept of"green travel, low carbon life", providing a safe and convenient way to travel. Despite the rapid expansion of greenway construction in China, however, there are many common design problems relating to connection, continuity, separation accessibility and services. These are key areas of greenway performance, and improvements are needed as key factors to ensure high quality greenway designs.

交通与发展政策研究所（Institute for Transportation and Development Policy,简称ITDP）成立于1985年，总部位于纽约，是一家非营利机构，其宗旨是推广在环境、经济、社会方面可持续发展的交通政策，并支持示范性交通运输方案，致力于公共交通（尤其是大运量公交系统）和非机动交通工具的推广、交通需求管理，以及土地利用规划的改善等。

The Institute for Transportation and Development Policy（ITDP）was founded in 1985 and had been headquartered in New York. IDTP is a non-profit organization whose purpose is to promote environmental, economic and social aspects of sustainable transport policies and support exemplary transport programs. ITDP dedicates itself to public transport（particularly mass transit systems）, the promotion of non-motorized transport, transportation demand management, and improvement of land-use planning.

ITDP近二十年来一直致力于绿道和慢行系统的研究及相关项目设计，拥有世界顶级的绿道专家团队。绿道在中国发展伊始，ITDP第一时间就介入到其规划、设计和建设进程中。在过去的几年里，ITDP一直致力于高品质绿道的设计，基于广州、东莞、惠州、天津、北京、武汉、宜昌等城市的实际情况，结合ITDP团队的国际绿道规划、设计及建设经验，提出了适合中国城市发展的绿道规划与设计准则，希望对未来中国绿道的建设有所助益。

ITDP has carried out greenways and NMT research and project design for 20 years. Now ITDP has a world-class greenway expert team. As soon as the construction of greenways began in China, ITDP was involved in the design, planning and construction process. In the past few years, ITDP has been committed to enhancing good greenway design and planning in Chinese cities including Guangzhou, Dongguan, Huizhou, Tianjin, Beijing, Wuhan and Yichang drawing from local and international experts. This research includes development of urban greenway planning and design principles in several cities. ITDP hopes that these efforts will help in the process of greenway construction in China in the future.

ITDP的工作不仅限于绿道的建设，也致力于推动可持续交通在全球的发展。ITDP在世界银行、欧洲复兴开发银行、亚洲开发银行定位城市交通政策时扮演着重要的角色，在联合国可持续发展委员会制定交通部分策略方面也发挥了重要的作用，并编写了联合国发展计划署的交通政策。2010年3月，ITDP在广州合法注册了广州市现代快速公交和可持续交通研究所，推动中国城市可持续发展的交通模式发展。目前ITDP已经与广州、兰州、天津、武汉、哈尔滨、宜昌等城市签订了合作备忘录，为他们的可持续交通项目（BRT、NMT、绿道、公共自行车和停车管理等）提供技术支持，其中广州及宜昌BRT交通走廊结合绿道的规划、设计及建设分别荣获多项国际大奖，也期待着未来更多的城市能够取得类似的成功。

ITDP's work is not only about the construction of greenways, but is also committed to promoting the development of sustainable transport around the world. ITDP plays an important role when the World Bank, the European Bank for Reconstruction and the Asian Development Bank set their urban transport policy. In addition, at the United Nations Commission on Sustainable Development, ITDP plays an important role in the strategy, and edits the transport policies of the United Nations Development Programme. In March 2010 ITDP was registered in China as the Guangzhou Modern BRT and Sustainable Transport Institute, in order to promote sustainable modes of transport and urban development. ITDP has signed cooperation memoranda with the cities of Guangzhou, Lanzhou, Tianjin, Wuhan, Harbin and Yichang, so that ITDP can provide technical support while these cities continue their traffic projects in areas of BRT, NMT, greenways, bike sharing and parking management. The Guangzhou and Yichang BRT corridors planned with key inputs from ITDP, which both include greenway components, have received major international prizes. ITDP looks forward to having the chance to achieve similar successes in more cities in the future.
