5.10. Cable median barriers. The barriers are intended to prevent (or at least reduce the number and severity of) crashes caused when a vehicle crosses the median of a divided highway and enters the lanes of oncoming traffic. A DOT staff member surveys four states and finds: 1436 miles of cable median barriers (CMBs) have been installed in those states. CMBs cost an average of about $145,000 per mile to install and about $6500 per mile per year to maintain The expected life of a CMB is 20 years. The average number of fatalities on highway sections where CMBs have been installed has dropped from 64.4 per year to 3.4 per year. A. What is the EUAC of total CMB installation and maintenance in the four states? Use discount rated - 3.1 percent B. At what value of a human life will the cost of the CMBs be justified, strictly on an economic basis? 5.11 . Valu. 5.10. Cable median barriers.
