“…Some studies investigated the impact of work zone barriers (cone pylons, concrete jersey barriers and metal barriers) on driver behavior [24], while some analyze drivers' behavior under different climatic conditions like foggy conditions and reduced visibility [25,29,30]. Most of the simulator studies investigated the impact of different kind of message signs on driver's route choice and compliance behavior, diversion of traffic, speed patterns, sign effectiveness and safety of traffic [20,[26][27][28][29]31]. This study focuses on work zone safety and evaluates the influence of three different work zone signs-speed photo enforced signs, DSDS and reduced speed limit signs-on driver speeding behavior using a medium-fidelity driving simulator.…”
