SHOULDER USE

A STUDY WAS CONDUCTED TO DETERMINE THE FREQUENCY OF USE OF SHOULDERS FOR LEISURE STOPS AND FOR EMERGENCY STOPS ALONG STATE HIGHWAYS. DATA RECORDED INCLUDED: TYPE OF VEHICLE, STATE OF REGISTRATION, TIME OF STOPPING, TIME OF RESUMING TRIP, LATERAL DISTANCE FROM EDGE OF PAVEMENT, NUMBER OF OCCUPANTS, PURPOSE OF STOP, DIRECTION OF TRAVEL, DISTANCE FROM OTHER VEHICLES ON SHOULDER, AND LOCATION OF STOP LONGITUDINALLY. DATA COLLECTED SHOWED THAT: (1) EMERGENCY PASSENGER CAR STOPS OCCUR ONCE FOR EVERY 13,450 PASSENGER CAR MILES, (2) EMERGENCY TRUCK STOPS OCCUR ONCE FOR EVERY 5200 TRUCK MILES, (3) EMERGENCY STOPS OCCUR ONCE FOR EVERY 11,800 VEHICLE MILES WITH 20% TRUCKS, (4) LEISURE PASSENGER CAR STOPS OCCUR ONCE FOR EVERY 980 PASSENGER CAR MILES, (5) LEISURE TRUCK STOPS OCCUR ONCE FOR EVERY 154 TRUCK MILES, (6) LEISURE STOPS OCCUR ONCE FOR EVERY 480 VEHICLE MILES WITH TRAFFIC 20% TRUCKS, (7) PASSENGER CARS MAKE LEISURE STOPS 13.7 TIMES AS FREQUENTLY AS THEY MAKE EMERGENCY STOPS, (8) TRUCKS MAKE LEISURE STOPS 33.8 TIMES AS FREQUENTLY AS THEY MAKE EMERGENCY STOPS, AND (9) WITH 20% TRUCKS THERE ARE 24.6 TIMES AS MANY LEISURE STOPS AS EMERGENCY STOPS.
