THE TWO-LEVEL NO-WEAVE INTERCHANGE

THE AUTHOR EXAMINES THE PROBLEMS ASSOCIATED WITH 'AT-GRADE' JUNCTIONS AND THOSE ASSOCIATED WITH WEAVING, AND CONSIDERS THAT THE MOST SATISFACTORY SOLUTION TO THE INTERSECTION PROBLEM IS THE INSERTION OF GRADE-SEPARATED INTERCHANGES WHERE WEAVING IS ELIMINATED. THE RELATIVE MERITS OF DIRECT AND INDIRECT INTERCHANGES ARE BRIEFLY DISCUSSED AND THE AUTHOR CONCLUDES THAT THE INDIRECT INTERCHANGE IS LIKELY TO PROVE THE MOST SATISFACTORY, PARTICULARLY IN VIEW OF THE DIFFICULTIES ASSOCIATED WITH SPREADING THE INDIVIDUAL HIGHWAYS TO ACCOMODATE DIRECT CONNECTION RAMPS. FOUR-LEG RIGHT-ANGLED INTERSECTIONS ARE ANALYSED IN DETAIL AND A METHOD OF SPECIFYING RIGHT-TURN CONNECTIONS FOR TWO-LEVEL, NO-WEAVE INTERCHANGE PATTERNS IN SYMBOLIC TERMS DEVELOPED. THE AUTHOR SHOWS THAT THERE ARE ONLY 17 BASIC FORMS OF INTERCHANGE SATISFYING HIS CONDITIONS FOR TWO-LEVEL NO-WEAVE INTERCHANGES AND THAT THESE MAY BE EXPANDED INTO 82 PATTERNS IN 484 POSSIBLE COMBINATIONS WHICH WILL SATISFY THE CONDITIONS FOR A NO-WEAVE RIGHT TURN. /AUTHOR/
