We are exploring possibilities that include computer vision to identify street assets, integration of traffic data, and measurement of multimodal access to opportunities. There are many opportunities to expand Pedestrians First.
For example, it is still difficult to clearly represent the presence and quality of sidewalks in OSM and assessing the safety of street crossings remains a pressing concern.
However, other aspects have been challenging to work with, and prevent us from measuring other important indicators of pedestrian-friendliness. Certain aspects of the OSM data model have been critical to the success of the project, especially its emphasis on representing connectivity, its typology of streets, and its relative uniformity around the world. We have found OpenStreetMap an invaluable tool in identifying and measuring the most important elements of walkability. Other factors matter at the level of the neighborhood, such as the proximity of destinations, and still others are at the level of the entire city, like the ability of a public transit system to move pedestrians from one neighborhood to another. Some factors, like sidewalk quality, matter at the small scale, the level of the street or the city block. To be walkable, a city must prioritize pedestrians not only in urban design but also in land use and transportation planning. This talk will describe what makes a city walkable, discuss the experience of using OSM to measure walkability, and explore possibilities for improving that measurement in the future.īecause the experience of walking is so natural, it is easy to assume that planning walkable cities is equally simple. Responding to that need, the Institute for Transportation and Development Policy has released Pedestrians First, a tool that supports planners and decision-makers by using OSM to measure what matters for walkability in cities. In the face of the climate crisis, there is an urgent need to build cities that are sustainable and inclusive. Around the globe, cities have been designed for cars rather than pedestrians, resulting in enormous costs to the environment, the economy, and even the social fabric of our communities. During this talk, we will examine the nature of walkable and unwalkable cities, we will discuss the opportunities and limitations of using OSM to measure walkability, and we will consider possible avenues for extending Pedestrians First in the future.įew modern cities are walkable. Pedestrians First is a new open-source suite of tools for using OSM data to measure indicators of urban walkability. Walkability is the foundation for urban life that is sustainable, inclusive, healthy, and dignified.
