Summary
This paper proposes a novel architecture for an interactive, motion-based traffic simulation environment called the Networked Motion-Based Interactive PEdestrian and Driving Simulator (n-MIPEDS). The research is motivated by the limitations of existing driving simulators, which often fail to capture realistic interactions between actual human users and background traffic, particularly regarding congestion phenomena like spillback and spillover. To enhance modeling realism, the proposed system integrates four distinct simulation types: motion-based driving, pedestrian movement, motorcycling/bicycling, and traffic flow. This integration allows actual drivers, pedestrians, and cyclists to navigate a simulated network while interacting with fully simulated background traffic. The methodology employs a hybrid mesomicroscopic traffic flow simulation approach to balance computational efficiency with realism. A mesoscopic model, utilizing DynusT© for dynamic traffic assignment, propagates traffic across the entire network based on user equilibrium solutions. Simultaneously, a microscopic model generates detailed background traffic in the immediate vicinity of the actual human users. These two models interact continuously to update system conditions based on user actions. The architecture utilizes a multiplayer framework where client modules (representing cars, bikes, or pedestrians) connect to a central simulation server via LAN or internet. The server runs parallel simulations and manages communication using the Common Object Request Broker Architecture (CORBA) to ensure interoperability across different platforms and languages. Key components of the system include a SimCraft three-axis motion-based driving simulator for the "virtual driver," a pedestrian simulator using Microsoft Kinect to capture body movements, and a bicycle/motorcycle simulator with a motion base. The virtual reality environment is generated using a hierarchical, data-driven approach that imports geometric data from Open Street Maps and 3D models from sources like Google SketchUp and Blender. This allows for the automated creation of realistic roadway networks, including landmarks, buildings, and traffic controls, specifically demonstrated using the Las Vegas road network. The system dynamically renders only the visible area for each user to optimize performance. The significance of this work lies in its ability to study complex transportation phenomena involving actual humans in a safe, controlled environment. Unlike existing models that rely on artificial entities or limited corridor simulations, n-MIPEDS enables the simultaneous study of interactions among drivers, pedestrians, and bikers with infrastructure and safety technologies. Potential applications include evaluating distracted driving, testing safety mechanisms like automatic braking systems, and training emergency personnel. While implementation challenges regarding multiplatform integration remain, the architecture offers a comprehensive framework for analyzing traffic safety and behavior with higher fidelity than current alternatives.
