Examines interactions among several stakeholders representing different decision perspectives in a partially connected-automated multimodal transportation system. InterchangeSE will allow complex simulated scenarios involving live and virtual participants. It will be developed based on existing virtual reality/augmented reality technologies and a software architecture with connectivity and communications between independent hardware and software components. This project will enhance the system architecture with built-in fault tolerance and integration with a performance monitoring system. The platform will demonstrate inclusion of future technologies such as wearable textile stress biosensors and a head-mounted augmented reality display.
