Abstract: A network device receives, from multiple smart cameras located at different road segments of multiple real-world road segments, first data describing a location and configuration of each of the multiple real-world road segments, and second data describing movement of one or more objects at each of the multiple real-world road segments. The network device generates multiple virtual road segments based on the first data, wherein each of the multiple virtual road segments describes one of the multiple real-world road segments; and uses a physics engine to simulate, based on the generated multiple virtual road segments and the second data, movement of vehicles or pedestrians through the multiple real-world road segments to analyze traffic characteristics, trends or events. The network device generates road segment alterations for reconfiguring one or more of the multiple real-world road segments based on the analysis of the traffic characteristics, trends, or events.

Abstract: A device can receive data related to a roadway. The data can include video data of the roadway. The device can determine a pixel area of objects shown in the video data. The device can determine that a vehicle and an individual are associated with the roadway at a same time. The device can determine a protective zone around the individual based on a first pixel area of the individual. The protective zone can be associated with detecting a potential collision between the vehicle and the individual. The device can determine a first location and movement of the vehicle relative to a second location and movement of the individual. The device can predict that a second pixel area of the vehicle is to intersect the protective zone of the individual. The device can detect the potential collision. The device can perform one or more actions.
