JOURNEY-TO-WORK STATISTICS

THE COMPREHENSIVE TRANSPORTATION PLANNING PROCESS REQUIRED BY THE 1962 FEDERAL-AID HIGHWAY ACT FALLS INTO TWO PHASES: BENCH-MARK AND CONTINUING. ELEMENTS OF EACH ARE NOTED WITH RELATION TO DATA COLLECTION AND ANALYSIS AND MODEL DEVELOPMENT, THE COST FOR THE PROCESS BEING ABOUT ONE DOLLAR PER RESIDENT OF THE AREA UNDER CONSIDERATION. IN SPITE OF THE LARGE COST, HALF OF WHICH IS GENERALLY SPENT FOR DATA COLLECTION AND PROCESSING, PLANNING ESTIMATES ARE PROBABLY LESS ACCURATE THAN THEY CAN BE BY JUDICIOUS USE OF TRIP-TO-WORK DATA AND CORRELATED INFORMATION CONTAINED IN THE 1970 CENSUS. THE MAJOR INNOVATION HAS BEEN GEOGRAPHIC CODING OF THE RESIDENCE AND WORK ADDRESSES OF RESPONDENTS TO THE BLOCK LEVEL. THIS IS A SIGNIFICANT INCREASE IN ANALYTICAL ABILITY, PARTICULARLY IN REGARD TO WORK LOCATION STATISTICS. BLOCK LEVEL STATISTICS CAN SERVE AS THE BASIC ELEMENT IN AN AGGREGATION PROCESS, SO THAT CENSUS DATA CAN BE SUMMED TO ANY AREA SYSTEM OF INTEREST. FHWA HAS PREPARED A SPECIAL PROGRAM THAT WILL PRODUCE A SUMMARY TAPE OF A DEFINED SET OF TABULATIONS THAT WILL PROVIDE ZONAL DATA NEEDED BY URBAN STUDIES. THE COST WILL BE REASONABLE, AND THE STANDARDIZED PACKAGE WILL INCUR NONE OF THE PROBLEMS NORMALLY ATTENDANT TO SPECIAL REQUESTS. THE PACKAGE CONTAINS A TRIP TABLE AND TABULATIONS AT THE ZONE OF RESIDENCE, ZONE OF EMPLOYMENT, AND AREA-WIDE LEVEL. THE TRIP TABLES GIVE WORK TRIPS FROM ALL ZONES TO ALL ZONES. USES AND PROBLEMS OF THE PACKAGES ARE DESCRIBED.
