SS4A is a system wide safety analysis that reviews all modes of transportation and how they interact, connect and safely navigate the streets, roads, bike lanes and sidewalks within the cities of Lewiston and Auburn. This study will review high crash rate locations throughout the cities and make recommended safety improvements for each city to review and consider for implementation. It will review and recommend improvements to each city's planning polices, active transportation network, street speed limits, traffic calming techniques and work towards reducing fatalities and serious injuries consistent with the Vision Zero and Safe Systems approach to transportation infrastructure within the two cities.
