Roadway Through Lanes in Kentucky

This feature service provides access to the spatial dataset that represents roadway centerline sections that serve as the main lanes for through traffic. These lanes are designed for vehicles to travel continuously without the need to exit or merge, improving traffic flow and safety. By separating through traffic from merging or turning movements, these lanes help reduce the risk of collisions and enhance roadway efficiency. The number of lanes designated for through traffic is provided in the attribute (tabular) data, allowing for detailed analysis of roadway capacity and traffic patterns. This selection is made by the Kentucky Transportation Cabinet (KYTC), Division of Planning, for apportionment, administrative, legislative, analytical, and pavement performance analysis/reporting purposes. This dataset supports transportation planning, traffic safety analysis, and infrastructure management in alignment with guidelines from the American Association of State Highway and Transportation Officials (AASHTO), the Federal Highway Administration (FHWA), and the Highway Safety Improvement Program (HSIP). It is also used by KYTC, the Kentucky Department of Transportation (KY DOT), and the U.S. Department of Transportation (US DOT) to improve roadway design and traffic management.
