In the following majorminor and yieldcontrolled intersection

In the following major-minor and yield-controlled intersection, the minor approach has +5% (uphill) grade. The major road has a 55 mph speed (N-S). the offset of the building to the major road: 60 ft; the offset to the minor road : 100 ft. Please determine the appropriate design speed for the minor road (E-W)

Solution

According to equilibrium condition,

55×60=100×y

=y=33 mph

Because approach are same for both
