INTRODUCTION
• The ability to accommodate high volumes of traffic safely
and efficiently through intersections depends largely on thearrangements provided for handling intersecting traffic.
• The greatest efficiency, safety, and capacity are attained
when the intersecting traveled ways are grade separated.
