USE OF IBM PORT-A-PUNCH IN ORIGIN-DESTINATION SURVEYS

THE PORT-A-PUNCH SYSTEM DEVELOPED BY IBM TO SIMPLIFY DOCUMENTATION OF DATA WAS APPLIED IN AN ORIGIN-DESTINATION SURVEY. STANDARD IBM CARDS ARE USED WITH UP TO 40 PERFORATED COLUMNS OF 12 PUNCH POSITIONS EACH. THE CARDS ARE INSERTED IN A PLASTIC BOARD WITH SLOTS UNDER THE COLUMNS USING A PENCIL-LIKE STYLUS PUNCH TO PERFORATE ACCORDING TO THE DESIRED INFORMATION. THE CODING FOR VEHICLE TYPE AND TRIP PURPOSE WERE MEMORIZED BY THE INTERVIEWER. ROADBLOCKS AT THE SURVEY SITES WERE SET UP AND NEARLY EVERY VEHICLE WAS INTERVIEWED. INTERVIEWERS PUNCHED THE CARD AS INFORMATION WAS OBTAINED. IT WAS CONCLUDED THAT THE USE OF THE PORT-A- PUNCH SYSTEM FOR ORIGIN-DESTINATION SURVEYS PROVIDED: (1) A MEANS FOR THE INTERVIEWERS TO PRODUCE MORE USABLE INTERVIEWS FASTER WITH A MINIMUM OF TRAFFIC DELAYS AND MOTORIST IRRITATION, (2) THE PRE-CODING REDUCED OFFICE CODING BY ABOUT 31 PERCENT, (3) KEY PUNCHING WAS ELIMINATED ENTIRELY, (4) INTERMEDIATE PAPER WORK WAS ELIMINATED, (5) TABULATED RESULTS WERE DELIVERED TO ANALYSTS WITHIN FIVE MONTHS FROM START OF SURVEY, AND (6) IT IS ANTICIPATED THAT TABULATED RESULTS CAN BE OBTAINED IN FIVE WEEKS OR LESS AFTER COMPLETION OF FIELD WORK.
