An one-lane minor street crosses a four-lane major street, with traffic conditions of four hours peak volume (both directions on major street) is 1000 veh/h and the volume minor-street approach (one direction only) is 300 veh/h. With pedestrian volume of 90 ped/hr during (at same four peak hours) and the number of gaps per hour in the traffic stream for pedestrians to cross during peak pedestrian periods is 61. The intersection is warranted for:

The average normal flow of traffic on cross roads A and B during design period are 400 and 250 pcu per hour; the saturations flow values on these roads are estimated as 1250 and 1000 pcu per hour respectively. The all-red time required for pedestrian crossing is 12 secs. Design two phase traffic signal by Webster's method.
A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?
The normal flow of traffic on crossroads A and B are 400 and 250 vehicles per hour respectively. The saturation of flow for roads A and B are estimated as 1250 and 1000 vehicles per hour respectively. The all-red time for pedestrians to cross is 12 seconds. Design a two-phase traffic system by Webster's method.
During the peak hour, an urban freeway segment has a traffic flow of 6,000 veh/h, with 4,000 vehicles with one occupant and 2,000 vehicles with two occupants. The freeway has five lanes, four of which are unrestricted opening to all vehicles regardless of vehicle occupancy and one lane that is restricted for use by vehicles with two occupants. Link performance functions for the length of this freeway segment are tu = 30+ 0.5vu for the unrestricted lanes and tr = 20+2vr for the restricted lane, where t’s are in minutes and v’s are in 1,000 vehicles. Solve for the distribution of traffic among the lanes using the SO principle and compare the savings in person hours relative to a UE solution, assuming that the compliance is perfect and that no single-occupant vehicles use the restricted lanes.
A two-lane minor street crosses a four-lane major street, with traffic conditions of volumes for each eight hours of an average day (both directions on major street) is 450 veh/h and the volume minor-street approach (one direction only) is 96 veh/h.

Q3b. The 15km Atta Mills road connecting Old Barrier to Kokrobite operates with a capacity of 2250 pcu/hr and can be traversed within 15 minutes under free flow conditions. If a flow of 3100 pcu/hr is assigned to the road based on the capacity-restrained approach, what would be the resultant travel time after the traffic assignment proce ss.
