Reference no: EM13727564

2. What is the Free-Flow-Speed (FFS) for the following conditions

(i) a lane width of 12 ft, right shoulder lateral clearance of 1ft(2 lanes), and total ramp density of 2 (TRD=2 ramps/mi).

(ii) a lane width of 10 ft, right shoulder lateral clearance of 5ft (3lanes), and no ramps

3. Find the analysis flow rate v(p).

(a)For a Peak hour factor of 0.8, number of lanes N=4. Assume fhv=0.9, and fp=1

(b)For Peak hour factor of 0.7, N=3, Assume fhv=0.8, and fp=1

4. Two routes connect a city and a suburb. During peak hour the travel times on both routes are given by the following equations:
Route 1:
T1 = 6+3x1
T2 = 4 +9x2
The total flow x1 + x2 =4.
Time T1 and T2 are in hours. Find the equilibrium flow (x1 and x2) and also the equilibrium travel time
