PURPOSES : The effect of yellow carpet visibility enhancement was verified and its impact on traffic safety for effective introduction of traffic safety facilities was studied. METHODS : There is currently no scientific evidence demonstrating that yellow carpets improve pedestrian awareness. In this study, the effect of increasing visibility caused by the installation of yellow carpet was verified, and the effect of improving the level of traffic safety was examined through an objective analysis. A drone was used to collect and analyze video data to compare the driving speeds of vehicles passing near yellow carpets at six different sites and diagnose the effects of speed reduction. RESULTS : The results showed that the visibility improvement values before and after the installation of the yellow carpet differed from place to place, but a visibility improvement effect existed in certain cases. In terms of the adequacy of the installation site, the yellow carpet had no deceleration effect on vehicles driving on signalized local streets and collector highways. It was found that there was a speed reduction effect on unsignalized local streets. CONCLUSIONS : To enhance traffic safety promotion, yellow carpets should be placed on unsignalized local streets. It is important to place the yellow carpet in the right place in a proper manner.
