<br />and for the detour is: <br /> <br />___~Q(10.3) (6530) (2) (4.75) <br />TC(Q) = (35)(24) = (TdQ)(760.7) $/hr <br /> <br />e <br /> <br />The loss of time in dollars due to use of the detour is: <br /> <br />TCL(Q) = TdQ(760.7 - 235) = (TdQ)(525.7) $/hr <br /> <br />7.3.4 Accident Costs <br /> <br />Increased accident costs are based on death rate statistics. For each <br />death, there are assumed a certain number of personal injuries and property <br />damage accidents. The personal injuries and property damage losses are <br />obtained by applying property damage and personal injury rates to the costs <br />of damage and injury. The rate and cost data may be site specific or based <br />on national statistics. These losses are computed on a vehicle mile basis and <br />are a function of ADTE, length of detour, duration of detour, ratios of <br />personal injuries and property damage accidents to deaths, costs of personal <br />injuries and property damage accidents. <br /> <br />The cost of accidents is computed by: <br /> <br />AC = 1 g[(Time) (ADTE) (Length) (Death Rate)][(Accident/Injury Factor)] <br />2.4x10 <br /> <br />Accident/Injury Factor = [(Injury Ratio)(Unit Cost of Injury)+(Damage e <br />Ratio)(Unit Cost of Damage)], <br /> <br />and the dollar loss due to increased accident exposure on the detour is: <br /> <br /> <br />ACL = (AC for detour) - (AC for normal route) <br /> <br />Where: <br /> <br />Time is in hours (Time of Detour) <br />ADTE is in vehicles per day <br />Length is in miles <br />Death ratio is in people per 100 million <br />vehicle miles <br />Injury rate is in injuries per death <br />Damage ratio is in damage per death <br />Unit cost of injury is in dollar per lnJury <br />Unit cost of damage is in dollars per damage claim <br /> <br />e <br /> <br />48 <br />
