Rainfall-intensity dependent accident probabilities with VSLs of (a) 2000 veh/h, (b) 1500 veh/h, (c) 1000 veh/h, and (d) 500 veh/h. The curve “a” indicates the results of N_ac/N which experimented with v_max1 = 120 km/h and v_max2 = 90 km/h, “b” indicates the results with v_max1 = 100 km/h and v_max2 = 70 km/h, “c” indicates the results with v_max1 = 80 km/h and v_max2 = 50 km/h, “d” indicates the results with v_max1 = 60 km/h and v_max2 = 40 km/h, “e” indicates the results with v_max1 = 40 km/h and v_max2 = 30 km/h.
