2040 Comprehensive Plan: Envision Shakopee

Vehicle and Pedestrian Collision Speed and Survival Percentage

ENACT A COMPLETE STREETS POLICY A Complete Streets Policy balances the multi-modal needs of all people traveling, whether they are walking, bicycling, using public transit, driving automobiles or operating freight vehicles. A Complete Streets Policy guides the community in making transportation decisions that better serve walking and bicycling trips, while maintaining access and mobility for transit, automobiles and freight. An effective Complete Streets policy has 10 elements:

When a vehicle is traveling at...

Resources such as the Complete Streets policies for other Minnesota communities and those provided by the National Complete Streets Coalition can be valuable in determining what these ten elements mean for Shakopee. In addition, they offer ideas for ways to advance surface water, recreation, aesthetic and economic development goals, in addition to transportation goals, through “green” or “living” streets. A Complete Streets policy should be paired with bicycle and pedestrian policies in order to fully address all the transportation implications.
