A developer has applied for a construction permit to build a supermarket at the southeast corner of an intersection that is formed by a four-lane divided highway in the east-west direction and a two-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop sign at the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight triangle requirements at the intersection (Case B1), determine whether permission should be given for the construction if the following conditions exist. Provide a diagram for your solution. Major road lane width = 3.6 m Minor road lane width = 3.3 m Median lane = 2.8 m Design vehicle is a passenger car Approach grade = 2% Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 m Maximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m

Major road lane width = 3.6 m
Minor road lane width = 3.3 m
Median lane = 2.8 m
Design vehicle is a passenger car
Approach grade = 2%
Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 m
Maximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
