Route selection studies are often used to identify the optimum route for roadway realignments or new transportation infrastructure.

For existing roadways, the goal of the route selection study is to examine traffic operational impacts associated with the proposed development/closure and to determine the extent of roadway modifications necessary to assure smooth, efficient and effective traffic operations within the vicinity of the development/closure such as levels of service, impacts to on-street parking and required left-turn storage.

For new transportation infrastructure, the goal of the route selection study is to address traffic operational impacts, cost-benefits, interconnectivity with surrounding properties, property requirements, and economic development impacts.
