城市人行道：为行动不便的人提供可视化和路线选择
Urban sidewalks: visualization and routing for individuals with limited mobility
摘要：
在美国，行动不便的人（定义为在没有帮助和不使用特殊设备的情况下难以或无法行走四分之一英里）面临着越来越大的信息差距：虽然行人路线规划算法变得越来越快，信息量越来越大，但由于缺乏关于路线沿线可达性的综合相关信息，在城市中心使用轮式设备规划路线非常困难。此外，减少进入街道空间意味着减少获得其他公共信息和服务的机会，而这些信息和服务正越来越多地沿城市街道向公众提供。为了充分规划通勤，行动能力有限或有轮子的旅行者必须知道她的道路是否会被建筑物阻挡，人行道是否会太陡或由于条件差而无法使用，街道是否可以穿过或高速公路是否挡住了路，或者是否有人行道。这些详细信息在许多现代城市中填充了不同的数据集，但它们并不能立即以方便的集成格式提供给行动不便的人。我们的项目，EMOMAP，在其第一阶段（v.1）覆盖的信息，最相关的人在地图上的行动不便，使自我规划的路线。在这里，我们描述了该项目的下一阶段：综合常用的开放数据（包括街道，人行道，路边坡道，高程数据和施工许可证信息），以生成路径图，从而实现可变成本函数可访问路由。
英文摘要：
People with limited mobility in the U.S. (defined as having difficulty or inability to walk a quarter of a mile without help and without the use of special equipment) face a growing informational gap: while pedestrian routing algorithms are getting faster and more informative, planning a route with a wheeled device in urban centers is very difficult due to lack of integrated pertinent information regarding accessibility along the route. Moreover, reducing access to street-spaces translates to reduced access to other public information and services that are increasingly made available to the public along urban streets. To adequately plan a commute, a traveler with limited or wheeled mobility must know whether her path may be blocked by construction, whether the sidewalk would be too steep or rendered unusable due to poor conditions, whether the street can be crossed or a highway is blocking the way, or whether there is a sidewalk at all. These details populate different datasets in many modern municipalities, but they are not immediately available in a convenient, integrated format to be useful to people with limited mobility. Our project, AccessMap, in its first phase (v.1) overlayed the information that is most relevant to people with limited mobility on a map, enabling self-planning of routes. Here, we describe the next phase of the project: synthesizing commonly available open data (including streets, sidewalks, curb ramps, elevation data, and construction permit information) to generate a graph of paths to enable variable cost-function accessible routing.
