Question
An existing urban freeway with 4 lanes in each direction has the following characteristics.
Traffic data:
Peak hour volume (in the peak direction):
7,110 veh/h
Trucks:
10% of peak hour volume
PHF = 0.93
Geometric data:
Lane width:
11 ft
Shoulder width:
6 ft
Total ramp density:
1.8 ramps per mile
Terrain:
rolling
Determine the LOS in the peak hour. (Assume commuter traffic and assume no RVs.)
LOS A LOS B     LOS C LOS D LOS E LOS F
Show the demand flow rate (in pc/h/ln), mean speed (in mi/h), and density (in pc/mi/ln) for the given conditions.
