- Compute the peak hour factor if the hourly volume of traffic is 1969 veh/hour and the highest 15-min volume is 737.Compute the peak hour factor if the hourly volume of traffic is 1882 veh/hour and the highest 15-min volume is 790. Round off to two decimal places.The peak hour factor for a traffic during rush hour is equalto 0.60 with a highest 5-min volume of 250 vehicles. The space meanspeed of the traffics is 90 kph, Compute the spacing of vehiclesin meters
- During peak hours, 3800 vehicles pass through a certain highway from 9:00 AM to 11:00 AM, withspace mean speed of 20 kph. What is the average space headway per vehicle in meters?A rail transit system has prescribed the following factors:1. Peak hour demand = 30000 passengers/hr2. Minimum required speed = 55 ft/sec3. Deceleration = 3 ft/sec24. Safety factor = 1.455. Vehicle length = 80 ft6. Allowable vehicle capacity = 150 pass/veh7. Guideway utilization factor = 0.838. Minimum headway = 110 secHow many cars should the train consist of to provide adequate passenger capacity?The traffic intensity of a certain freeway is 0.833. The arrival rate of vehicles at a certain intersection (stop sign) is 200 vehicles per hour. Compute the service rate in vehicles/hr. *
- 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.Compute the rate of flow in veh/hr if the space mean speed is 35 mph and the density of traffic is 17 veh/km.The average queue length at the intersection of the two roads with a stop sign is 4 vehicles. If the arrival rate of vehicles at the stop sign is 300 veh/hr, determine the service rate of the road in veh/hr. Assume both arrival and departure rates are exponentially distributed.
- vehicle time headway is 2.5 sec/vehicle and the spacingof cars measured at a point along the North Luzon Expresswayfrom a single lane is 60 m/veh over the course of an hour.a. Compute the traffic density.b. Determine the space mean speed in kph c. compute the average speed of the trafficDuring peak hours, 3800 vehicles pass through a certain highway from 9:00 am to 11:00 am, with space mean speed of 20kph. What is the average space headway per vehicle in meters?Vehicles arrive at an entrance to a recreational park. There is a single gate (at which all vehicles must stop), where a park attendant distributes free brochures. The park opens at 8:00 AM. At which vehicles begin to arrive at a rate of 480 veh/h. After 20 minutes, the arrival flow rate declines to 120 veh/h and corrtinues at that level for the remainder of the day. If the time required to distribute the brochure is 15 seconds, and assuming D/D/1 queuing (a) draw the queuing diagram (b) describe the operational characteristics of the queue (maximum queue length, maximum queuing time, average queuing time per vehicle etc.)
