Six-mile Long Freeway
1.A westbound section of freeway currently has three 12-ft wide lanes, a 6-ft right shoulder, and no ramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.9. If the road is expanded to four 11-foot lanes with a 2-foot right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and peak-hour factor, what is the new LOS and estimated density?
2. A six-mile long freeway segment has 5 lanes in the northbound direction. The lanes are 10-ft wide and there is a 3-ft right shoulder. There are 8 on/off ramps in this section. What is the estimated FFS at the mid-point of this six-mile segment?
