123456 Assume that the real risk-free rate of return, pis 3 percent, and it will remain at that level far into the future. Also assume that maturity risk premiums on Treasury bonds increase from 0 percent for bonds that mature in one year or less to a maximum of 2 percent, and MRP increases by 0.2 percent for each year to maturity that is greater than one year (that is, MRP equals 0.2 percent for a two-year bond, 0.4 percent...
A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions 4 ft from the right edge of the pavement. There are 4 ramps within 6 miles. A directional peak-hour volume of 4500 veh/h is observed, with 1250 vehicles arriving in the highest 15-min flow rate period. The traffic stream contains 15% heavy vehicles. What is the density and the corresponding level of service (LOS) of the traffic stream? Do not use on the chart...
