WebApr 1, 2014 · An appropriate deceleration length could reduce the speed differential, thus reducing crash frequency and severity. Total crash frequency, crash rate, crash index, and percentage of severe crashes of each site were plotted in Fig. 2(a)–(d), associated with the deceleration lane lengths. The figure reveals the correlation between the crash ... WebΔx = ( 2v + v 0)t. \Large 3. \quad \Delta x=v_0 t+\dfrac {1} {2}at^2 3.
