Accessibility
无障碍
Accessibility is a measure of the degree to which travel opportunities and destinations are available in a region，city，town，or building.
无障碍（可达性）是衡量一个地区，城市，城镇或建筑物的作为旅游和目的地程度的标尺。
In urban design terms，it is the ease with which it is possible to reach a location from another location by public transit，private vehicle，bicycle，or as a pedestrian.
在城市设计方面，通过公共交通工具，私人车辆，自行车或行人可以轻松地从另一个位置到达某个位置。
The presence of a diverse mix of land uses and activities within close proximity is the most important factor for high accessibility.Connectify enhances accessibility since a robust network of streets can reduce the travel time and the difficulty of reaching a particular location.
土地的混合使用和近在咫尺的活动是高可达性的最重要因素。连通性增强了可访问性，因为强大的路网可以减少通达的时间和到达特定位置的难度。
Fast-food establishments，drive-through services，big-box retail，and other developments that can only be accessed by automobile are inaccessible to people who cannot drive or do not own an automobile.For example，the number of seniors unable to drive safely is increasing，but the auto-centric model of development discriminates against such nondriving populations.Auto-centric forms are unsustainable and should not be emulated，especially in developing countries.
不懂驾驶或没有汽车的人无法进入快餐店，直通车服务，大型零售店以及其他只能通过汽车进入的设施。例如，不能安全驾驶的老年人数量正在增加，但以自助为核心的发展模式将这些不开车的人群拒之门外。以自助为核心的开发形式是不可持续的，不应该被模仿，尤其在发展中国家。
At the scale of a building，all spaces that serve the public should be universally accessible to everyone irrespective of their disabilities，race，color，sex，national origin，age，and religion.The Americans with Disabilities Act（ADA） requires that commercial spaces and large multifamily buildings be accessible to those who are unable to climb stairs.Barriers to access formed by stairs and other changes in level is a factor that merits particular attention by designers.
在建筑物的规模上，所有为公众服务的空间应该是每个人都可以普遍使用的，无论他们是否残疾，或种族，肤色，性别，国籍，年龄和宗教信仰如何。美国残疾人法案（ADA）要求商业空间和大型多户住宅建筑可以提供给那些无法爬楼梯的人使用。由于楼梯或其他高差变化引起的通行障碍是设计师特别关注的一个因素。
The ADA allows disabled individuals to participate in activities to be productive citizens.It recognizes that barriers to employment，transportation，public accommodations，public services，and telecommunications have imposed staggering economic and social costs on society.By addressing and removing barriers，the civil rights of individuals with disabilities is protected.
美国残疾人法案（ADA）承诺残障人士积极地参与活动以成为有生产力的公民。但必须认识到通行障碍给社会的各个方面，包括就业，交通，公共设施，公共服务和电信等，造成了惊人的经济和社会代价。通过解决和消除通行障碍，才能使每一个残障公民的权利受到保护。
