WRONG-WAY TRAFFIC MOVEMENTS OF FREEWAY RAMPS

Special cameras purchased from the California DOT were used by Georgia Tech to monitor the wrong way traffic movements at 45 representative off-ramps in the Greater Atlanta Freeway System. Countermeasures were installed and evaluated at nine of these locations. Recommendations for a statewide program of counter-measures were presented. The report includes an annotated bibliography summarizing wrong-way research performed to date by California, Virginia, Georgia, etc. It was concluded that high rates of wrong-way entries are found in the Atlanta area at incomplete interchanges (where such entries are often intentional); and at loop off-ramps that have their crossroad terminal adjacent to the on-ramp. The main recommendations offered to the Georgia DOT were as follows: State policy should discourage the construction of these two types of design; the California DOT's standard sign package, supplemented by a painted stopbar, should be implemented statewide; and where loop off-ramps have their cross-road terminal adjacent to the on-ramp, an additional countermeasure is recommended: a crossroad median divider consisting of a row of ceramic buttons.
