Summary
This paper addresses the critical need for advanced simulation methodologies to evaluate Intelligent Transportation Systems (ITS), specifically Vehicle-to-Vehicle (V2V) and Infrastructure-to-Vehicle (I2V) technologies. The authors argue that while these technologies promise significant safety improvements, their slow adoption rate—projected to take up to three decades—will create a complex, mixed fleet of connected and legacy vehicles. Traditional single-seat driving simulators (SSDS) are ill-suited for this research because they rely on artificial intelligence (AI) to simulate other drivers, which fails to capture the realistic feedback patterns and collaborative behaviors inherent in multi-driver scenarios. Consequently, the paper advocates for Multiple Seat Driving Simulators (MSDS) as the necessary tool to study how ITS impacts the driving public and vehicle fleet dynamics. To address this gap, the authors describe the development of the Real-time Multiple Seat Simulator (RMSS) at the University of Central Florida. The RMSS network consists of three fixed-platform L3 PatrolSim police training simulators, each providing a 270-degree virtual environment with realistic vehicle controls. The system is designed to allow multiple human drivers to interact within a shared virtual environment simultaneously. To enhance research capabilities, the team integrated advanced data collection tools, including Seeing Machines eye trackers for visual attention analysis and iWorx physiological measurement systems for galvanic skin response, electroencephalogram, and heart rate variability. A significant technical challenge involved synchronizing four distinct software platforms (faceLAB 5, GE iSim Research Companion, LabScribe, and ePrime). The authors utilized Simple Network Time Protocol (SNTP) clients to synchronize data within 1/60th of a second and Virtual Network Computing (VNC) to manage experimental stimuli and interfaces across the network. The paper reports that the RMSS network is stable enough to collect data from two human drivers in tandem, with work ongoing to include a third. This setup allows for the simultaneous evaluation of multiple participants, significantly reducing experimentation time compared to sequential single-seat testing. Furthermore, the networked design enables "Wizard of Oz" scenarios, where research assistants control confederate vehicles to inject realistic human behavior into the simulation, overcoming the limitations of AI-controlled agents. This approach facilitates the study of complex interactions, such as team driving and verbal communication via V2V links, which were previously difficult to model accurately. The significance of this work lies in its potential to improve the ecological validity and efficiency of driving research. By linking simulators, researchers can generate cleaner, more representative data on multi-role driving situations, which is essential for developing effective ITS technologies that treat drivers as a group rather than isolated individuals. The authors conclude that linked simulation networks like the RMSS represent the future of driving research, enabling the demystification of driver interactions and supporting the development of ITS solutions that can effectively mitigate risks in a mixed-technology transportation grid.
