A temporary diversion has been constructed on a highway of -3% gradient due to major repairs that are being undertaken. Determine the speed limit that should be imposed on the diversion if drivers can see the sign inform ing them of the diversion at a distance of 400 ft from the diversion and the posted speed limit on the highway is 60 mph.
A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
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
