PURPOSES : In this study, we examined the installation and the effect of the s-type approach lane marking near the stop line of a typical intersection access road. We examined the possibility of installation and standardization of this facility and its impact on vehicular speed management and carbon emission reduction.
METHODS : To review the installation and standardization possibilities, the geometric size of the marking was set. The possibility of standardization was examined by applying it to lane markings. The velocity before and after the installation of the marking was compared and analyzed through the velocity estimation equation to assess the impact on speed management. Carbon emissions were estimated by comparing the emissions before and after applying the marking.
RESULTS : The s-type approach lane marking can be installed near the stop line of the intersection access road. It was possible to standardize the lane marking by suggesting a formula to determine the size of the geometry. Additionally, the marking enabled vehicular speed management and improvement in the carbon yield. The marking decreased speeds by approximately 10 km/h, from the original speed of 36 km/h to 25.5 km/h after installation. The standard deviation per vehicle was reduced by approximately 5.9 km/h, from 5.8 km/h to 0.9 km/h. Additionally, carbon emissions decreased by 17%, from 14.1 g/40 m to 11.7 g/40 m.
CONCLUSIONS : The geometry and size of the lane marking installation can be set near the stop line of the approach road. Standardization of this facility was also possible. The s-type lane marking, installed at the stop line of the approach road, has the potential to control the speed, reduce the acceleration or deceleration, and reduce the carbon emission. In the future, it is expected that such lane markings can be applied to multi-faceted areas
