Situational Awareness

The connected car is going to play a fundamental role in the foreseeable Internet of Things. The connectivity aspect in combination with the available data (e.g. from GPS, on-board diagnostics, road sensors) and video (e.g. from dashcams and traffic cameras) streams enable a range of new applications. Five connected cars applications have been developed on top of World Wide Streams. Anomalous Driving is a scenario that detects cars that are rapidly accelerating or braking. Potential users of these scenarios can be fleet managers and parents. The Congested Areas application detects clusters of abnormal deceleration behavior, indicating rapid slow-down of multiple cars within a short time frame and geographic perimeter. Potential users of the events can be other drivers in the vicinity.

Remote Video Monitoring enables traffic officers to use a collection of the dashcam feeds within an area of interest (e.g. accident scene or congested square/crossing) to obtain insights in real time. Amber Alert allows a privileged user (e.g., a police department administrator) to initiate a simultaneous and large scale search for a particular license plate number (e.g., of a stolen car) within a certain geo-fence (e.g., a city district) using the available dashcams. It uses the dashcams to do license plate recognition, potentially leveraging the processing power available in the car. Sightings are reported on the map. Users can navigate to the car that did the sighting and see its live dashcam stream for immediate context. Aggregate Statistics provides city managers with real-time distribution of various events of interest such as speed, fuel consumption, and CO2 emission.
