Websince it can significantly increase braking distance reproducibility. The braking distance of a train traveling at 50 m/s (180 km/h) is almost 150 m longer if sanding is activated manually with a three-second delay. Moreover, the sand output required to achieve the necessary adhesion is at least five times greater at 50 m/s than at 10 m/s. WebFeb 10, 2015 · The amended Federal Motor Vehicle Safety Standard ( FMVSS) 121 required a 30-percent reduction in stopping distance compared to the current standard. …
WebCurrently, stopping distance requirements under FMVSS No. 121, Air Brake Systems, vary according to vehicle type. Vehicles are tested under three different test conditions: (1) loaded-to-GVWR; (2) unloaded; and (3) emergency braking conditions. Under the loaded-to-GVWR condition, when stopping from 60 mph, air-braked buses WebStopping distance consists of three factors: • Driver’s reaction time • Brake lag • Braking distance C.
