A CLOSED CIRCUIT TELEVISION SYSTEM FOR TRAFFIC SURVEYS

A CLOSED CIRCUIT TELEVISION SURVEY SYSTEM WAS DEVELOPED IN RHODE ISLAND TO REPLACE ROADSIDE INTERVIEW SURVEYS. THE REQUIREMENTS AND GOALS OF THE SURVEY WERE TO USE CLOSE CIRCUIT TELEVIDION EQUIPMENT TO VIDEO TAPE ALL LICENSE PLATES, TO IDENTIFY THE LANE, TIME, AND DIRECTION OF TRAVEL OF EACH VEHICLE, TO SEARCH REGISTRY FILES FROM RHODE ISLAND, MASSACHUSETTS, CONNECTICUT AND NEW YORK FOR THE NAME AND ADDRESS OF THE DRIVER, OR OWNER, OF THE VEHICLE AND MAIL QUESTIONNAIRES TO THESE ADDRESSES TO OBTAIN INFORMATION OF THE TRIP BEING MADE AT THE TIME OF RECORDING. THE FOUR MONTHS PRIOR TO THE ACTUAL SURVEY WERE DEVOTED TO DEVELOPING A WORKABLE TELEVISION SYSTEM, TRAINING A SURVEYING CREW, DEVELOPING COMPUTER PROGRAMMING TECHNIQUES FOR RAPID ACCESSING OF REGISTRY FILES, AND DESIGNING AND PRINTING QUESTIONNAIRES. ATV ACTUAL SURVEY TIME A CLOSED CIRCUIT TELEVISION POSITIONED OFF THE ROADWAY RECORDED PLATE NUMBERS OF PASSING VEHICLES ON VIDEO TAPE, THE TAPES WERE THEN REVIEWED ON A TV MONITOR AND A SAMPLE SELECTED, THE SAMPLE SELECTIONS WERE THEN RECORDED ON CODING SHEETS ALONG WITH THE STATE OF REGISTRATION, TIME, DATE AND DIRECTION OF TRIP, THE INFORMATION KEYPUNCHED, USING STATE REGISTRY FILES THE PLATE NUMBERS WERE MATCHED WITH NAMES AND ADDRESSES, A QUESTIONNAIRE WAS THEN SENT TO THE OWNER OF THE VEHICLE, FILLED OUT AND RETURNED. THE ADVANTAGES OF THIS SYSTEM ARE THAT IT IS SAFER FOR THE SURVEYOR AS WELL AS THE DRIVER, THE MOTORISTS ARE NOT DELAYED, THE QUALITY OF THE DATA IS MORE CONSISTENT AND MORE DETAILED QUESTIONS CAN BE ANSWERED, AND THIS METHOD IS MORE ECONOMICAL.
