Step by step solutionProblem 3: A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 5-ft shoulders, and there are 3 ramps within 3 miles upstream of the segment midpoint and 3 ramps within 3 miles downstream of the segment midpoint. The freeway is on rolling terrain and has 10% heavy vehicles with a PHF of 0.9. It is known that 15% of the AADT occurs in the peak hour and the directional factor is 0.7. Determine: (a) Heavy vehicle adjustment factor(b) Free-flow speed(c) Capacity(d) Volume-to-capacity ratio(e) Density and LOS(f) AADT(g) What is the highest possible value of the heavy vehicle adjustment factor? (h) If the volume exceeds capacity, what is the LOS? Note: No need to show calculations for (g) and (h).
The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.
A new four-lane divided multilane highway (two lanes in each direction) is being planned with 12-ft lanes, 6-ft shoulders on both sides, and a 50-mi/h speed limit. One 3% downgrade is 4.5 mi long, and there will be 4 access points per mile. The peak-hour directional volume along this grade is estimated to consist of 1800 passenger cars, 140 SUTs, and 60 TTs. If the peak-hour factor is estimated to be 0.85, what level of service will this segment of highway operate under? What is the percent trucks - PT? What is the value of the passenger car equivalence factor - ET? What is the heavy vehicle factor - fHV? What is the median adjustment factor - fM?
