Summary
This paper introduces the Traffic Sign Simulator, an innovative research tool designed for the proactive evaluation of traffic signs and pavement markings. Motivated by the need to shift from reactive road safety measures to proactive design that accounts for human information processing limitations, the study aims to assess how road users detect, read, comprehend, and act upon traffic control devices before they are implemented in the field. The authors argue that existing methods, such as paper-and-pencil reviews, laptop tests, and traditional driving simulators, suffer from limitations regarding realism, behavioral control, or the ability to integrate visual and behavioral data. The Traffic Sign Simulator combines a driving simulator mock-up with high-definition video footage of real road environments. Using specialized camera-tracking and 3D video-integration software, researchers digitally insert virtual traffic signs into the recorded footage. Participants navigate these scenarios using a fixed-base mock-up equipped with steering wheels, pedals, and indicators, allowing them to actively control speed and lane choice. Visual behavior is monitored via a dash-mounted eye-tracking system (FaceLAB), while laptop-based pre- and post-tests assess sign comprehension, recall, and user suggestions. This integrated approach allows for the simultaneous analysis of detection, readability, understanding, and behavioral responses. The paper illustrates the tool’s application through a case study evaluating temporary work zone signalization for the reconstruction of the Vilvoorde fly-over in Belgium, a complex interchange with a time-dependent detour. Twenty-three volunteers participated in the study, which included a pre-test assessing their ability to recall and interpret the main announcement sign after brief exposure, followed by simulated drives through the detour scenario. The experimental design allowed researchers to monitor route choices, lane changes, and visual attention patterns while participants navigated the digitally modified environment. The study specifically investigated whether drivers understood the time-dependent detour, if sign repetition was necessary, and if incorrect route choices were likely. The significance of this work lies in providing a robust method for ex-ante evaluation of road infrastructure. By combining the realism of video-based simulation with the behavioral control of driving simulators and the objective measurement of eye-tracking, the Traffic Sign Simulator addresses the shortcomings of previous techniques. It enables road designers to identify potential comprehension errors and safety risks in traffic sign placement and design before implementation, thereby improving road safety and traffic flow, particularly in complex environments like work zones. The case study demonstrates the tool's capacity to generate actionable insights for optimizing traffic control plans.
