    Car following behaviours on multilane highways in Kuwait: A case study on road 40 during winter season by Alenzi, Eisa, Sitti Asmah, Hassan, Othman, Che Puan

    Published 2022
    “…In a condition, where the traffic volume is in a free-flowing situation, the selection of vehicles speed is typically limited by some factors such as weather conditions, lighting, and road geometry features. This study aims to investigate the effects of climates on driver’s car following behaviour and speed flow relationships for highways in Kuwait. …”
