“Bike Safety Plan” is an interface designed to show a plan of investment to extend the bicycle network in different cities optimizing safety. The investment plan is generated by an automated data-driven planning framework developed by P. Folco, L. Gauvin, M. Tizzoni and M. Szell which aims to 1) optimize safety using geolocated data in 2014, 2015, 2016 bike crashes; 2) integrate with the existing cycling infrastructure using the street network data; 3) develop a well-designed and cohesive urban cycle infrastructure network.
The interface allows you to set the number of km to add to the cycle network and shows the solution on the map. The points in the map are crashes involving at least 1 bicycle that occurred in years 2014, 2015, 2016. We label a crash as “covered” (gray points) if located within 50 m of a bicycle infrastructure element. Otherwise, we consider the crash as “not covered” (white points). When the “Kms of additional bike infrastructure” slider is set to 0 km, the existing cycling infrastructure of the city is displayed. When the slider is set to D km, the existing infrastructure + D km of investments are shown. In addition, the “crashes” counter indicates how many of the crashes in the data set would have been covered by adding this D km of cycle paths.
Crash data are made available by ISTAT, networks data are provided by OpenStreetMap.
