- Help For two circulating lane, Conflicting flow rate of 675 pc/hr . find total entry lane capacity.Plzz help For one circulating lane, Conflicting flow rate of 675 pc/hr . find total entry lane capacity.Assume that passenger car equivalents are 1.5 for trucks (ET), 1.6 for left-turns (EL), and 1.4 for right-turns (ER), and saturation flow qs= 160 x (curb-to-curb width / # of lanes) equivalent passenger-car units per hour per lane (pcu/hr/ln). Pedestrian walk speed (PS) is 4 ft/sec, and the effective width of crosswalk (WE) is 9 ft. Given that the intergreen time is 8.0 seconds and lost time is 3.5 seconds per phase, design a 2-phase signal timing plan using the Webster’s method.
- 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.6. A shared three-way pedestrian-bicycle facility has a width of 10 ft and carries a peak pedestrian flow of 500 p/15 min. The bicycle flow rate is 150 bicycles/h in the same direction as the pedestrians, and 160 bicycles/h in the opposite direction. The average pedestrians' speed is 4 ft/see, and that for bicycles is 8 ft/see. a) Determine the pedestrians' LOS b) Determine the LOS for the shared bicycle pathsThe average normal flow 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 1200 and 1000 pcu per hour respectively. The all-red time required for pedestrian crossing is 12secs. Calculate cycle time for two phase signal system.
- The following calculations are taken at the approach of an intersection during the morning rush hour. Determine (a) the hourly volume, (b) the peak flow rate in one hour, and (c) the peak hour factor.Analyze the unsignalized intersection below and calculate the optimum cycle length if the intersection will be signalized. Approach E W N S Maximum no. of lanes 5 5 4 4 Direction Through left Through left Through left Through left N Total volume pcu/hr 1,480 370 860 586 1,360 494 2,030 265 Sat. flow rate pcu/hr/lane 2,400 1,700 2,400 1,700 2,200 1,800 2,200 1,800Calculate green split for each approach (Eastbound, Westbound, Northbound, Southbound) using Webster method. Given: Two through lanes and one left turn lane; Saturation Flow Rate: Through = 1,900 veh/hr/ln and Left turn = 900 veh/hr/ln. Total lost time = 4 seconds.
- 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.The equivalent hourly flow rate for an approach with 125 vehicles in the peak 15 minutes and PHF = 0.92 would be:Determine the saturation flow rate (in veh/h) for a left-turn lane that operates in a permitted-only mode, under the following conditions. Opposing demand flow rate = 1,100 veh/h Lane width 11.5 ft Heavy vehicles = 4% of the traffic stream Approach grade -6% No on-street parking No bus stops Bicycle and pedestrian traffic conflicting with this lane group is negligible: Intersection is not in a central business district veh/h
