TRADE-OFF ANALYSES IN MAJOR INTERCHANGE DESIGN

RECENT EXPANSION OF LIMITED-ACCESS, HIGH-SPEED HIGHWAYS HAS EMPHASIZED THE NEED FOR SAFELY DESIGNED INTERCHANGES. FREQUENTLY, INTERCHANGES ARE DESIGNED AS MODIFICATIONS TO EXISTING DESIGNS TO INCREASE CAPACITY OR AS DEVELOPMENTS FROM EXPERIENCE OF DESIGNERS. A MORE ANALYTIC APPROACH IS NEEDED. IN THE STUDY REPORTED, EXISTING DESIGN CRITERIA ARE REVIEWED AND EVALUATED, AND A DECISION-THEORY APPROACH TO DESIGN IS DEVELOPED. THIS APPROACH ASSESSES THE RELATIVE OPERATIONAL AND SAFETY MERITS OF ALTERNATIVE INTERCHANGE CONFIGURATIONS AND SUGGESTS TRADE-OFFS BETWEEN THESE MERITS AND THE COST OF THE ALTERNATIVE.
