The Eight Principles of TOD are WALK, CYCLE, CONNECT, TRANSIT, MIX, DENSIFY, COMPACT, and SHIFT. They illustrate the relationship between transport and land use. These principles form the Framework for the TOD Standard, a universal tool that can be used to evaluate and plan neighborhoods.

In urban planning, transit-oriented development (TOD) is a type of urban development that maximizes the amount of residential, business and leisure space within walking distance of public transport. [1] [2] It promotes a symbiotic relationship between dense, compact urban form and public transport use. [3]

Status of TND • 600 + TND/TOD developments in U.S. as of 2010 • Range from neighborhoods to new towns • Model ordinances have been developed – “Form-based” codes to supplement or replace traditional zoning – “Complete streets” policies and ordinances

Traditional Neighborhood Development (TND) refers to the development of a complete neighborhood or town using traditional town planning principles. TND may occur in infill settings and involve adaptive reuse of existing buildings, but often involves all-new construction on previously undeveloped land.

在规划领域，有一个非常有名的理论，叫做TOD（transit-oriented development），即以公共交通为导向的开发。 就是说城市的发展规划一个区域的时候，可以通过建立便捷的公共交通中心来形成城市的发展聚集区，而那个中心就是交通枢纽。

The TOD Standard is a powerful tool to help shape and assess urban development. It focuses on maximizing the benefits of public transit and non-motorized mobility while placing the emphasis firmly back on the users: people.

Transit-Oriented Development with TND Pods. The backbone for the TOD is the Regional Transit System (RTS). Along that path are moderate and high density housing together with complementary public uses, places of employment, and supporting retail and other services.

TOD模式：以公共交通为导向的开发（transit-oriented development，TOD）是规划一个居民区或者商业区时，使公共交通的使用最大化的一种非汽车化的规划设计方式。 TOD即是指：“以公共交通为导向的发展模式”。 其中的公共交通主要是指火车站、机场、地铁、轻轨等轨道交通及巴士干线，然后以公交站点为中心、以400～800米（5～10分钟步行路程）为半径建立 中心广场 或城市中心，其特点在于集工作、商业、文化、教育、居住等为一身的“混合用途”，使居民和雇员在 …
