Abstract
Results obtained during the study of various speed limit methods, including uniform, differential, and lane-based methods, are presented in this paper. The results show that the LBSL strategy is by 20 % better than other methods when safety is considered, while its traffic performance is by almost 16 % lower compared to other methods. The results also show that traffic performance decreases approximately by 19 %, but safety increases roughly by 20 %, if the speed limit is reduced from 130 km/h to 100 km/h.
