Title: EFFECT OF CONTROL DEVICES ON TRAFFIC OPERATIONS - INTERIM REPORT
Accession Number: 00224778
Record Type: Monograph
Availability: Find a library where document is available Abstract: ALTHOUGH STOP AND YIELD SIGNS ARE ONLY TWO OF MANY TRAFFIC CONTROL DEVICES, THEY ARE OF PARTICULAR INTEREST BECAUSE OF THEIR WIDESPREAD USE, LOW INITIAL COST, AND EASE OF INSTALLATION. PILOT STUDIES WERE CONDUCTED IN THE CHICAGO AREA TO DETERMINE THE EFFECT OF THIS TYPE OF INSTALLATION ON TRAFFIC OPERATIONS. SPEED, VOLUME, GAP AND LAG ACCEPTANCE, TRAVEL TIME AND DELAY, SAFETY, HEADWAY DISTRIBUTION, ROUTE CHOICE, AND DRIVER ACTIONS DATA WAS OBTAINED BY USING TIME- LAPSE PHOTOGRAPHY, ENOSCOPE SPEED STUDIES, MANUAL COUNTS, DRIVER QUESTIONNAIRES, AND TRAVEL STUDIES. PARAMETERS FOR INDIVIDUAL INTERSECTIONS, THE MEASURABLE EFFECT FROM CONTROL OF ADJACENT INTERSECTIONS, TRAVEL PATTERN CHANGES RESULTING FROM NEW INSTALLATIONS OR CHANGE IN TYPE OF TRAFFIC CONTROL DEVICES WERE STATISTICALLY ANALYZED AND COMPARED WITH OTHER RESEARCH RESULTS. TRAFFIC SIMULATION ON ELECTRONIC COMPUTERS FOR AT-GRADE INTERSECTIONS WAS REVIEWED AND RECOMMENDATIONS WERE MADE FOR FURTHER STUDY OF DESIRABLE COMPONENTS OF THE SIMULATION MODEL. THE RESULTING DATA, WHEN CORRELATED, SHOULD AID IN OBTAINING BASIC OPERATIONAL CHARACTERISTICS WHICH ARE UNIVERSALLY APPLICABLE.
