Please correct answer
The 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.
On a city street, a transit line operates through signalised intersections. Each transit has three compartments, and each compartment can accommodate a maximum of 40 passengers. The acceptable green-to-cycle time ratio (g/C) to the particular street is 0.35. The clearance between successive transits should be 70 seconds. The passenger's dwell time is 110 secounds. The reduction factor for dwell time and arrival variation is 0.785. Estimate the capacity of the transit line in passengers/h. Answer: the capacity of the transit line = passengers/hour Report your answers to the nearest whole number without units (i.e., if your answer is 1720.258, you should enter 1720 or if your answer is 873.564, enter 874)
