Use the results of Problems 9-16 and 9-17 to compute: LOS, v/c, and veh-mi in the peak 15 minutes and peak hour, and total travel time in the peak 15 minutes. For the main direction (660 veh/h):
What will be an ideal response?
Step 1: LOS determination. See Table 9.11.
a) If Class I Highway:
- ATS = 37.88 mi/h
- PTSF = 76.83%
- LOS = E
b) If Class II Highway:
- PTSF = 76.83%
- LOS = D
c) If Class III Highway:
- ATS = 37.88 mi/h
- FFS = 48.25 mi/h
- PFFS = 78.51%
- LOS = C
Step 2: Ratio v/c. Use vd from ATS estimation, as it provides a higher v/c ratio.
Step 3: Estimate vehicle miles traveled. Use Equation 9.26
