A new section of Richmond Highway is being designed as a six-lane facility (three in each direction) with a two-way left-turn lane. Determine the peak-hour LOS. Traffic data: • Directional design hourly volume = 3600 veh/h • PHF = 0.94 • Assumed base free-flow speed = 55 mi/h (88 km/h) Geometric data: • Urban setting • Rolling terrain • Lane width = 11 ft (3.3 m) • Shoulder widths = 4 ft (1.2 m) (right side) and 1 ft (0.3 m) (left side) • Average access point spacing = 12 points per mile on each side

Question
A new section of Richmond Highway is being designed as a six-lane facility (three in
each direction) with a two-way left-turn lane. Determine the peak-hour LOS.
Traffic data:
• Directional design hourly volume = 3600 veh/h
• PHF = 0.94
• Assumed base free-flow speed = 55 mi/h (88 km/h)
Geometric data:
• Urban setting
• Rolling terrain
• Lane width = 11 ft (3.3 m)
• Shoulder widths = 4 ft (1.2 m) (right side) and 1 ft (0.3 m) (left side)
• Average access point spacing = 12 points per mile on each side
