ASSEMBLY, ANALYSIS AND APPLICATION OF DATA ON WARRANTS FOR TRAFFIC CONTROL SIGNALS

THE INITIAL STAGE OF WORK INCLUDED REVIEW OF EXISTING BIBLIOGRAPHIES, DIRECT CONTACTS WITH NUMEROUS RESEARCHERS, ORGANIZATIONS AND INDIVIDUAL TRAFFIC ENGINEERS. THE AREAS OF INFORMATION WERE DIVIDED INTO SIX GROUPS AS FOLLOWS: VOLUME, GAP AVAILABILITY, GAP ACCEPTANCE CHARACTERISTICS, DELAY, PEDESTRIANS, AND VEHICULAR CONTROL ACCIDENTS. A GENERAL REVIEW IS PROVIDED IN SEPARATE CHAPTERS COVERING EACH OF THESE SUBJECTS AREAS. THESE REVIEWS OF EXISTING WORK HAVE BEEN SUPPLEMENTED BY LOCAL STUDIES ON VOLUME, ACCIDENTS AND DELAY. THE TOTAL WORK PERFORMED BY ALL PARTIES HAS RESULTED IN THE DEVELOPMENT OF SUGGESTED WARRANTS. THE BASIC VARIABLE USES A DELAY EXPRESSION. THE WARRANT IS SUFFICIENTLY BROAD TO COVER ANY TYPE OF INTERSECTION, INCLUDING THOSE SUBJECT TO MINIMUM VOLUMES, INTERRUPTION OF CONTINUOUS TRAFFIC CONCEPTS AND HIGH-VOLUME DRIVEWAYS. A STREET SYSTEMS TYPE WARRANT IS ALSO INCLUDED. THE AREA OF PEDESTRIAN SIGNAL NEEDS IS COVERED BY A THIRD PROPOSED WARRANT, BASED ON DELAY DUE TO GAP AVAILABILITY VERSUS GROUP SIZE AND ROADWAY WIDTH. IN ORDER TO AID FUTURE RESEARCHERS IN THE AREA OF SIGNAL WARRANTS, THE BIBLIOGRAPHY HAS EXTENSIVE NOTATIONS. THE SINGLE AREA OF GREATEST SIGNIFICANCE FOUND FOR THIS STUDY IS THE COMBINED THEORETICAL AND FIELD VALIDATED SIMULATION MODELS. WHILE MUCH REMAINS TO BE DONE, THIS TOOL OFFERS TREMENDOUS POTENTIAL FOR MULTI-VARIANT ANALYSIS. /AUTHOR/
