Criteria for Repainting Color Pavement on residential road based on the driver's attitudes

Abstract

Color Pavement on road side belt that can be constructed even on narrow streets in residential areas has been increased in Japan. Although this traffic safety measure can be constructed early at low cost, it is necessary to repaint it regularly in order to maintain the effect as a traffic safety measure because color pavement often occurs to deteriorate over time. However, there is no clear criterion as to when to repaint color pavement, therefore, we have no choice but to decide the timing of repainting by subjective judgment rather than objective one. We examined criteria to repaint color pavement from a driver's point of view. Specifically, eye mark recorder and driving simulator were used to examine the influence of degradation of color pavement on the driver's gaze behavior and on driver consciousness. Based on these results, it is clarified that "peeling rate 40%" can be one criterion for repainting color pavement.
