Questions & Step-by-Step Solutions
What is the significance of the 'design vehicle' in highway geometric design?
Step 1: Understand what a design vehicle is. It is the largest type of vehicle that is expected to use the road.
Step 2: Recognize that the design vehicle affects how wide the lanes need to be. Wider lanes help larger vehicles fit comfortably.
Step 3: Learn that the design vehicle also influences the turning radii. This means how sharp or wide the turns need to be for larger vehicles to navigate safely.
Step 4: Realize that using the design vehicle helps ensure safety and efficiency on the road by accommodating the largest vehicles.
