1. A minor street approach intersection with a two-way, two lane divided roadway with a design speed of 45 mph and 12-ft-wide lanes. The roadway has a median that is 12-ft wide. The minor street approach grade is 5% and the design vehicle is a passenger car. If the minor road has a design speed of 30 mph then calculate the ISD for Cases A,B ,and C. 2. Determine if the following roadside design is consistent with the clear zone concept. The roadway has a 50-mph design speed and a design year AADT of 15,000 vehicles per day. If the design is insufficient, recommend a solution to improve the design. Travel lane Shoulder (8ft) 1V:5H (10 ft) 3.
