Refer The kerb-to-kerb turning circle is the minimum distance between two raised curbs, both of which are lower than the lowest body protrusions, in which the vehicle can make a U-turn. Turning circle is also sometimes used to refer to the path swept in the manoeuvre,[citation needed] i.e. completed, a loon may be used to provide additional space. Bus stop design should be based on the design parameters for articulated buses. Effects of driver characteristics (such as the speed at which the driver makes a turn) and the slip angles of wheels are minimized by assuming that the speed of the vehicle for the minimum radius (sharpest) turn is 10 mph (15 km/h) or less. WebWhat is the minimum turning radius for a bus?

All of them require awareness Measure from your first reference mark, where you started, to the furthest out of your other reference marks. As is, a 'bus' is designed by its function alone, and there are no minimum standards for wheelbase or overall turn length for the sake of Really depends on the wheelbase and overall length of the bus.
