How sustainable is urban transport in a given city and how can we quantify it? Zurich has pledged to be net zero by 2040.
In order to track a cities’ progress towards such goals suitable indicators must be put in place to assure accountability. The work of Maximilian and Ross proposes an urban mobility indicator, which measures the transport mix within a city to track change across time and space.
So called City Walking Tour Videos in short CWTVs are first-person, street-level videos of urban areas uploaded to video sharing platforms such as YouTube that contain information about the transport modes people use (e.g. pedestrians, cyclists, cars) at a given place. Mobility related information is automatically extracted with the help of object detection models and georeferenced based on detected street-names. The final policy indicator was tested based on the City of Paris which was chosen given its rapid changes of bicycle infrastructure in recent years.
