Please answer question 2 2. An intersection has a 2-timing stage signal with the movements allowed in each timingstage, analysis and saturation flow rates shown below. Consider that the lost time pertiming stage is 3 seconds and a critical v/c ratio of 0.85 is desired. Calculate minimumcycle length, and the effective green times (based on minimum cycle length).Timing Stage1EB LWB LAllowed movementsNB T/R SB T/RAnalysis flow rate (veh/h)1125 1075Saturation flow rate(veh/h) 600 600 3400 3200 650 600NBL SB L40 30100803. A six-lane urban freeway (3 lanes per direction) is on rolling terrain with 10-ft lanes,obstructions 5 ft from the right edge of the traveled pavement and 8 ramps within 3 milesupstream and 3 miles downstream of the midpoints of the analysis segment. A directionalweekday peak-hour volume of 2800 vehicles is observed with 760 vehicles arriving in themost congested 15-min period. The traffic stream has 7% single unit trucks and 3%tractor-trailer trucks.a. Determine the density and the LOS.b. If instead of rolling terrain, the freeway segment has an incline of 4.5% for adistance longer than 2 miles, determine the density and LOS.Timing StageAllowed movementsAnalysis flow rate (veh/h)Saturation flow rate(veh/h)Effective green (sec)1NBL SB L330 3651700 175013.94.
