SFT (StreetSafety) is an online platform where you can know the safety conditions of street interactions and design together to improve it! With transportation planners and street designers being the target user groups, SFT could be applied at public meetings, workshops, and charrettes. By integrating data visualization and interactive design, SFT facilitates the consensus building process and empowers the public to know better about the street conditions and try their own to make design improvements.
