Title: OPERATIONAL ROUTE ANALYSIS
Accession Number: 00227702
Record Type: Component
Abstract: THE MULTITUDE OF DATA COMPRISING THE ACCIDENT HISTORIES OF EXISTING HIGHWAY FACILITIES IN CONNECTICUT REQUIRE THE EXPENDITURE OF CONSIDERABLE MAN-HOURS IN EXECUTING ANALYSES AND CONDUCTING FIELD INVESTIGATIONS OF LOCATIONS WITH ACCIDENT CONCENTRATIONS. THE MILEAGE OF HIGHWAY NETWORK CONTINUES TO GROW AND THE MILES OF VEHICLE TRAVEL INCREASE AT AN EVEN GREATER RATE. AS A RESULT, THE TASK OF PROVIDING EFFICIENT ACCIDENT ANALYSES IS BECOMING OF SUCH MAGNITUDE AS TO THREATEN THE QUALITY OF THE ANALYSES AND/OR DELAY IDENTIFICATION OF ACCIDENT-PRONE LOCATIONS AND, THEREFORE, PROMPT APPLICATION OF REMEDIAL MEASURES. THE CHARACTERISTICS OF THE PROBLEM STIMULATED A REVIEW OF VARIOUS PROCESSING AND INVESTIGATING TECHNIQUES WITH REGARD TO EFFECTIVENESS, PERSONNEL, AND EQUIPMENT INVOLVED, AND TO EASE OF APPLICATION. THE METHOD SELECTED INVOLVES A STATISTICAL EVALUATION OF ACCIDENTS BY CONTRASTING THE PERTINENT ACCIDENT RATES AGAINST THE ROADWAY MEAN AND INVIDUAL CONTROL LIMITS TO DETERMINE THE RANGE OF FREQUENCY THAT COULD BE EXPECTED TO RESULT FROM CHANCE OCCURRENCE. THIS APPLICATION, WHILE MONITORING THE OCCURRENCE LEVELS AND DISTINGUISHING BETWEEN THE CHANCE EVENTS AND INCIDENTS REQUIRING ATTENTION, ENABLES THE CONCENTRATION OF PERSONNEL IN THE MORE CRITICAL AREAS AND THEREBY ELIMINATES THE NECESSITY FOR ANALYZING ALL ACCIDENT DATA TO OBTAIN THESE SENSITIVE LOCATIONS. RESULTS OF THE TEST APPLICATION INDICATED, WITHOUT A DOUBT, THAT THE METHOD EMPLOYED WAS EFFECTIVE IN POINTING OUT AREAS REQUIRING SPECIAL ATTENTION, AND COULD BE IMPLIMENTED WITH A MINIMUM NUMBER OF ENGINEERING PERSONNEL. INDICATIONS ARE THAT THE BULK OF MATHEMATICAL COMPUTATIONS CAN BE ACCOMPLISHED BY USE OF AN ELECTRONIC COMPUTER WITH A RELATIVELY SIMPLE PROGRAM. /AUTHOR/
