A tool used to determine the minimum space required for a vehicle to make a complete turn. This is calculated based on factors like wheelbase and steering angle, often providing a diameter or radius measurement. For instance, urban planners might use such a tool to ensure adequate turning space in parking garages, while a truck driver might use it to judge maneuverability on narrow roads.
Understanding a vehicle’s turning requirements is crucial for safe and efficient operation. Historically, this information was found in vehicle manuals or estimated through experience. Now, digital tools offer greater precision and accessibility, benefiting drivers, urban designers, and other professionals. This ability to precisely calculate turning space contributes significantly to safety by minimizing the risk of collisions in confined areas and improving the overall design of roadways and parking facilities.
