TRANSITION CURVE-PROJECT AND LOCATIONS

TABLES THAT ALLOW FOR THE LOCATION OF THE CLOTHOID BY DEFLECTION FOR THE WHOLE STAKING +10, AS EASILY AS THE USUAL FORM (FRACTIONARY) OF STAKING ARE GIVEN. A GREATER NUMBER OF RAYS (RC) THAN THOSE ALREADY IN USE WERE TABULATED. IN TABLE IV ARE THE ELEMENTS OF THE TRANSITION CURVES CORRESPONDING TO DIVERSE 71 RC. TRANSITION CURVES MAY BE CALCULATED AND LOCATED WITH ANY RC VALUE USING THE TABLES III AND IV. THEORETICAL STUDY OF THE TRANSITION CURVE IDENTIFIED FORMULAS WHICH ALLOW FOR THE DETERMINATION OF THE PARAMETERS OF THAT CURVE (RC, LC, XC, ETC). THE PROBLEM OF RELOCATION IS ALSO CONSIDERED. A METHOD MORE EXACT AND MORE SIMPLE THAN THAT OF THE PAVING MANUAL OF THE NATIONAL HIGHWAY DEPARTMENT, IS SUBMITTED AS A SOLUTION FOR THIS PROBLEM. THE CLOTHOID CAN BE LOCATED ALSO FROM THE TABLES BY THE COORDINATES METHOD, ALTHOUGH IT IS MORE DIFFICULT. /RRI/
