IDS houses a small-scale (1:25) “smart” city (SSC). SSC includes 35 robotic vehicles and can replicate real-world traffic scenarios in a small and controlled environment. This testbed can help us prove concepts beyond the simulation level and understand the implications of errors/delays in the vehicle-to-vehicle and vehicle-to-infrastructure communication as well as their impact on energy usage. It can also help us visualize how a “smart” city would look in the future by demonstrating coordination of vehicles in different traffic scenarios, such as intersections, merging roadways, speed reduction zones, and roundabouts. SSC can also be used to understand the implications of next-generation transportation systems consisting of CAVs, electric vehicles, and shared mobility on energy consumption and transportation efficiency. SSC also has a rural area where about 20 drones can fly so that we can investigate complex missions for unmanned autonomous systems for military types of applications.
