Impact of speed limit method on motorway safety

Mustafa Adressi, Ali Mohammad Baghalishahi, Maryam Zeini, Abolfazl Khishdari

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.
