Rainfall-intensity-dependent accident probabilities at (a) vmax1 = 100 km/h and vmax2 = 70 km/h, (b) vmax1 = 80 km/h and vmax2 = 50 km/h,(c) vmax1 = 60 km/h and vmax2 = 40 km/h, and (d) vmax1 = 40 km/h and vmax2 = 30 km/h. Curves “a”, “b”, “c”, and “d” indicate the results at inlet traffic volumes of 2500 veh/h, 1500 veh/h, 1000 veh/h, and 500 veh/h.
