Session Title: Vision Zero: Program Development, Implementation and Lessons Learned

Session Description: First implemented in Sweden in the 1990s, Vision Zero represents a paradigm shift in strategy to address transportation safety.  Vision Zero no longer regards traffic crashes as accidents but rather as preventable incidents that can be systemically addressed through cross-disciplinary collaboration.  In recent years, cities across the US have committed to Vision Zero principles with a clear goal of eliminating traffic fatalities and severe injuries.  In this session you will hear different perspectives of Vision Zero programs from some of the cities that have made the commitment: Bethlehem, Philadelphia, and Denver.
