A SIMULATION MODEL OF A TWO-LANE RURAL ROAD

A SIMULATION MODEL HAS BEEN DEVELOPED TO EVALUATE TRAFFIC FLOW AND SAFETY BENEFITS ARISING FROM USE OF REMEDIAL DEVICES WHICH WOULD AID PASSING MANEUVERS ON TWO-LANE RURAL ROADS. INPUTS TO THE MODEL ARE ARBITRARY AND CONSIST OF ROAD CONFIGURATION DATA, VEHICLE DATA, TRAFFIC VOLUMES, AND PASSING PROBABILITY DATA. THE OUT-PUT STATISTICS CAN BE USED TO DETERMINE THE RELATIVE BENEFITS OF ALTERNATIVE REMEDIAL AID SYSTEMS IN TERMS OF SAFETY AND THROUGHPUT. INITIALLY THE EFFECTS OF NO-PASSING ZONE CONFIGURATIONS DUE TO ROAD GEOMETRY AND KNOWLEDGE OF ONCOMING CAR SPEED ON TANGENTS WERE INVESTIGATED. THE RESULTS SHOW THAT NO-PASSING ZONES CAUSE A MARKED DECREASE IN THROUGHPUT, WHILE ONCOMING CAR SPEED INFORMATION APPEARS TO HAVE A BENEFICIAL EFFECT ON SAFETY. ADDITIONAL RUNS WILL BE MADE TO STUDY THE EFFECTS OF OTHER PASSING RULES ON TRAFFIC FLOW AND SAFETY. /AUTHOR/
