MOBILE WARNING EQUIPMENT FOR MAKING ROAD CONSTRUCTION SITES SAFE. REPORT OF EXPERIENCE WITH THE NEUSS CONGESTION WARNING EQUIPMENT

MOBILE WARNEINRICHTUNGEN ZUR VERKEHRSSICHERUNG VOR BAUSTELLEN. ERFAHRUNGSBERICHT ZUR STAUWARNANLAGE NEUSS

SINCE SEPTEMBER 1978 A MOBILE CONGESTION WARNING DEVICE DEVELOPED BY THE BUNDESANSTALT FUER STRASSENWESEN (GERMAN ROAD RESEARCH ASSOCIATION) HAS BEEN IN OPERATION ON AN APPROACH TO A CONSTRUCTION SITE ON THE A57 MOTORWAY NEAR THE NEUSS MOTORWAY TRIANGLE. THE EQUIPMENT CONSISTS OF FOUR MATRIX SIGNS SET UP AT THE RIGHT HAND SIDE OF THE ROAD, WHICH ARE SUPPLIED WITH CURRENT FROM COMMERCIAL ACCUMULATORS AND REMOTELY CONTROLLED MANUALLY BY RADIO IN A CENTRAL CONTROL SYSTEM. MEASUREMENTS TO TEST EFFECTIVENESS HAVE SHOWN THAT IT IS POSSIBLE TO INFLUENCE TRAFFIC POSITIVELY BY MEANS OF MOBILE WARNING EQUIPMENT. IT WAS POSSIBLE TO ACHIEVE A REDUCTION IN OVERALL SPEEDS, A REDUCTION IN THE SPEED DIFFERENCES OF FOLLOWING VEHICLES, AND THUS IMPROVE THE UNIFORMITY OF THE TRAFFIC FLOW. THE RESULTS FOR TRAFFIC ON OVERTAKING LANES ARE PARTICULARLY MEANINGFUL. IN THE CHANGEABLE DISPLAYS STVO (GERMAN HIGHWAY CODE) SIGN NO 101 WITH THE WORLD "STAU" (CONGESTION) IS ALTERNATED WITH THE WORD STAU COMBINED WITH A YELLOW FLASHING LIGHT. THE STVO SIGN GAVE SOMEWHAT BETTER RESULTS AS REGARDS THE REACTION OF ROAD USERS. EXISTING MATRIX SIGNS MAY BE SUPPLEMENTED BY OTHER STVO SIGNS.
