Complete streets has goal public security
Complete streets is a transportation policy and design approach that requires streets to be planned, designed, operated and maintained to enable safe, convenient and comfortable travel and access for users of all ages and abilities regardless of their mode of transportation. Complete Streets allow for safe travel by those walking, cycling, driving automobiles, riding public transportation, or delivering goods.The term is often used by transportation advocates, urban planners, traffic and highway engineers, public health practitioners, and community members in the United States and Canada.
Complete Streets are promoted as offering improved safety, health, economic, and environmental outcomes. Complete Streets emphasize the importance of safe access for all users, not just automobiles.

Complete streets policies are meant in part to improve safety, and various studies suggest that Complete Streets principles have done so. A Federal Highway Administration safety review found that designing the street with pedestrians in mind—sidewalks, raised medians, turning access controls, better bus stop placement, better lighting, traffic calming measures, and treatments for disabled travelers—all improve pedestrian, bicyclist and motorist safety.  Rates of pedestrian injuries and fatalities decrease 88% when sidewalks are added, 69% hybrid beacon signals are added, and 39% when medians are added. The University of Oregon published a before and after study of 25 complete street projects and found significant automobile speed crash reductions for projects throughout the country.
