ADVANCED PHOTOGRAMMETRIC TECHNIQUES FOR HIGHWAY INTERCHANGE GEOMETRY

THE DOCUMENT GIVES A VERY COMPREHENSIVE PRESENTATION OF THE APPLICATION OF THE LEAST SQUARES METHOD (LSM) TO THE SOLUTION OF VARIOUS GEOMETRICAL PROBLEMS THAT OCCUR IN HIGHWAY AND INTERCHANGE DESIGN AREAS. THE REPORT INCLUDES DISCUSSIONS ON THE SUMULTANEOUS ADJUSTMENT OF CRITICAL POINTS, SUCH AS, P.I., P.T., P.C., P.C.C., P.R.C., AND OTHERS. ALTHOUGH IT COVERS AN EXTENSIVE THEORETICAL INVESTIGATION, INCLUDING THE USE OF MATRIX ALGEBRA, THE HIGHLIGHT OF THE REPORT IS A DESCRIPTION OF AN APPLICATION OF LSM TO THE PROBLEMS OF DESIGNING, STAKING AND CONSTRUCTING HIGHWAY INTERCHANGES. FOR DESIGN, THE INVESTIGATOR'S SYSTEM, USING LSM, GIVES COMPLETE INFORMATION ABOUT THE ALINEMENT, SUCH AS, CURVE LENGTHS, CENTRAL LENGTHS, CENTRAL ANGLES, DEFLECTION ANGLES, TANGENTS, AZIMUTHS OF TANGENTS AND RADII, STATIONING AND COORDINATE VALUES FOR VARIOUS POINTS. FOR STAKING, THE LSM APPROACH CAN GIVE THE PLANE COORDINATES OF ANY POINT ON THE ADJUSTED ROAD OR RAMP ALINEMENT. THE COORDINATE INFORMATION CAN BE USED SUBSEQUENTLY IN COMPUTING THE HORIZONTAL ANGLES FOR STAKING PURPOSES. FOR CONSTRUCTION, THE LSM APPROACH, IN CONJUNCTION WITH PHOTOGRAMMETRY, CAN BE USED FOR CHECKING CONSTRUCTION ACCURACY OF INTERCHANGE RAMPS. /BPR/
