All Walks DC advocates for more Open Data for DC’s transportation system. According to the Open Knowledge Foundation, open data is “data that can be freely used, re-used and redistributed by anyone – subject only, at most, to the requirement to attribute and share alike”.
Open data is good for a city for a number of reasons: it provides better transparency of government actions, it allows better citizen participation in government, it allows for innovation in services, it can help government improve the efficiency of its services, and it can help measure the effectiveness of government policies.
DC has an existing Open Data policy, but it has not yet been applied to some aspects of transportation. During her campaign, Mayor Bowser promised to extend open data to more aspects of transportation that relate to walking. More open data will support the new Vision Zero initiative, headed by DDOT, by allowing citizens and non-profits to accurately track Vision Zero progress, and help to understand what is working and what is not.
Specifically, All Walks DC is advocating for the following data to be made public and open, published regularly, online, in an accessible (excel, csv) and georeferenced (latitude & longitude) format:
- Crash Data – Understanding where and how crashes happen is critical to tracking improvements to the safety of the transportation system. See this example from New York City.
- Traffic Violations – Understanding how and where traffic laws are being enforced can help the public to push for enforcement to be targeted where safety problems are worst. See this example from Montgomery County.
- Public Space Closures – Understanding the when and how public space, such as sidewalks and bicycle lanes are closed can help to understand if these are affecting safety and if closures are in compliance with existing accommodation policies. See this example from Cambridge, MA.
