Summary
This document outlines the objectives and methodology of the “Driving Simulation Forward” project, an Exploratory Advanced Research (EAR) Program initiative launched by the Federal Highway Administration (FHWA) in 2009 and conducted by the University of Iowa. The research addresses a critical gap in highway engineering: the difficulty of incorporating complex driver behavior into roadway designs, which can lead to safety failures and costly infrastructure rebuilds. While driving simulators are valuable tools, their utility is limited by a widespread mistrust regarding the reliability of simulator data. Specifically, simulator results often fail to match on-road performance data, and different simulators frequently produce conflicting results for similar scenarios. The project aims to resolve these discrepancies by establishing a systematic, design-centered approach to reconcile simulator data with real-world on-road data. The study employs a system-oriented technical approach that begins by gathering input from roadway designers to define necessary simulator characteristics based on specific design issues. The methodology involves building common scenarios across a range of simulators to collect comparative data on driver performance. This data is then analyzed against existing on-road performance metrics. The core objective is to develop mathematical transformation functions that relate specific simulator characteristics to expected on-road performance. Additionally, the team is developing a matrix that relates specific design issues to appropriate simulator platforms, acknowledging that not all simulators are suitable for every design challenge. This multi-method approach seeks to address the overwhelming variety of road situations and simulator configurations by providing engineers with tools to select appropriate simulators and transform their results. The significance of this research lies in its potential to make driving simulators more practical and reliable for highway designers. By creating a system to select simulators and reconcile their results, the project aims to support a broader range of applications, including vehicle safety system design, highway design evaluations, driver assessment, and training. The development of transformation functions is expected to advance the understanding of the perceptual and motor control processes that govern driving performance. Ultimately, the project seeks to ensure that technological advances in driving are evaluated effectively to promote positive effects on traffic safety, driver acceptance, and transportation efficiency, thereby addressing one of the “grand challenges” in driving performance research.
