The average normal flow of traffic on cross roads A and B during design period are 400 and 250 PCU per hour, the saturation 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 sec. What is the optimum cycle time by Webster's method?

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.
You are designing a freeway as a passenger-car-only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a peak-hour factor of 0.88, and a directional distribution of 0.65. day. It is estimated that the freeway will have a free flow speed of 70mi/h. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume. Use k =0.11.
There are 3 vehicles observed in a 100 m section of McArthur highway. If the average time headway is 4 sec., compute the space mean speed of the vehicles in kph. thank you
A 6-lane urban freeway is suggested to be designed with the following data: F.ADT = 45000 vpd, design hour factor= 0.12 and directional split = 65%. Rolling terrain, 10% trucks, 5% buses, 6% Rvs, PHF is 0.91 and all traffic are commuters. Then based on the HCM 2000 procedure, the equivalent passenger- car hourly flow rate is about
The minimum cycle length for an intersection is determined to be 95 seconds. The critical lane group flow ratios were calculated as 0.235, 0.250, 0.170, and 0.125 for phases 1–4, respectively. What Xc was used in the determination of this cycle length, assuming a lost time of 5 seconds per phase?

Assume you are observing traffic in a single lane of McArthur Highway at a specific location. You measure the average headway and average spacing of the vehicles as 3.2sec. and 50 m. respectively. Determine the traffic flow in vehicle/hour.
Determine the approximate center to center spacing of vehicles in a certain lane if the average speed of the cars using that particular lane is 40 kph and the volume of traffic is 800 vph
1) A 6-lane two-way arterial road has a maximum flow of 6,000 vehicles per hour on one direction. It is operating at 3,600 vehicles per hour at time, t=0. A collision occurs, blocking the two lanes, and restricting the flow of the outermostlane to 1,600 vehicles per hour. After 40minutes, the police have cleared the middlelane from accident debris; the operating volume at that time increased to 2,400 vehicles per hour.20 minutes past, the innermost lane was finally cleared of the accident. Traffic returns to normalas soon as the queue has already immoderate. a.Determine the maximum length of queue that occurred. b.How long did it take to dissipate the queue? c.If a vehicle entered the road at t=10 minutes, how long will it take for it to leave the traffic?
