I recently measure the cul-de-sacs in my neighborhood, which measured at 80 ft in diameter. Some argue that turning circle is less ambiguous than turning radius, but "turning circle" may introduce its own ambiguities since the same circle can be defined by multiple measurements, including the radius 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. They are generally the assumed operating vehicle in BRT or open BRT systems. What are the dimensions of a 72 passenger school bus? In real-world situations, this turning radius would vary depending on wheel tilt, friction, and many other factors. Turning radius Weights are approximate due to equipment options. To make turns at its tightest radius, the bus must slow significantly, which can cause run-time delays, especially if turns are frequent along a route. Typically, a bench at a bus stop has a height ranging between 18 and 20 inches (45.7 and 50.8 cm). Weights are approximate due to equipment options. The link shows an outer radius of 45'.
