- Plz, solve this problem. Transportation Engineering-2 A four-lane highway (2 lanes in each direction) with 3.65m lanes has a horizontal curve designed for a 380 m centerline radius, and a 110 km/hr design speed. The grade is level. Use a driver perception reaction time of 2.5 sec and a vehicle deceleration rate of 3.4 m/sec2. Determine the closest distance any roadside object may be placed to the centerline of the inside lane of the roadway.(note: Do not round any value. Use calculated values).A 2 lane highway with a grade of 6% has a posted speed limit of 50 mph and a design speed of 55mph. The minor road approach grade is -3%. Find the right turn departure sight distances for a passenger car taking a right turn from the minor road to the major road. Answer should be in feet.Determine the minimum stopping sight distance on a -3.5% grade for a design speed of 110 kph. Coefficient of friction between tires and pavement is 0.28.

The measured free-flow speed is 46.0 mi/h. The peak-hour volume is 1900 veh/h, PHF is 0.90, and there are 13% trucks and 2% RVs. Determine the LO, speed, and density.A two-lane minor road intersects a two-lane undivided major road at 90 degrees,forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building islocated 185ft from the center line of the outside lane of the major road. The design speed on themajor road is 60 mi/h and the design speed on the minor is 35 mi/h. The approach grade on the minorroad is 3%. A passenger car on the minor road would like to cross the major road. Using theAASHTO procedure, determine the minimum distance required that the building must be from thenearest lane on the minor roadA building is located 19 ft from the centerline of the inside lane of a curved section of highway with a 400 ft radius. The road is level; e = 0.10. Determine the appropriate speed limit (to the nearest 5 mph) considering the following conditions: stopping sight distance and curve radius. Assume f= 0.15
