A two-lane minor road intersects a four-lane undivided major road at 90 degrees,forming a four-leg intersection with traffic on the minor road controlled by a stop sign. The designspeed on the major road is 80 km/h. The approach grade on the minor road is 5%. A single unit truckon the minor road would like to make a left turn onto the major road. Using the AASHTO procedure,determine the minimum sight distance required on the major road for the truck to make a left turnonto the major road.
for the utility in problem 8-3, will the utility pole be located too close to the road if it is on the outside of a horizontal curve with a radius of 2,000 f?
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 is located 50 m from the center line of the outside lane of the major road and 14 m from the center line of the nearest lane of the minor road. A passenger car on the minor road would like to cross the major road. Using the AASHTO procedure, determine the maximum speed that can be allowed on the minor road if the design speed on the major road is 80 km/h. Assume a 3% approach grade for the minor road.
Note: 1km/hr = 0.62mi/h, 1ft = 0.3048m

- 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.

The prevailing speed of traffic on the approaching tangent section is 62 mph. Calculate the advance placement distance upstream of the curve PC for this sign (to the nearest foot). Also indicate the appropriate sign to be used (curve or turn) and the appropriate safe advisory speed if one is to be posted for this curve.arrow_forward
