Abstract: Techniques for determining information about an event by one or more devices proximate to a roadway are described herein. For example, a device (e.g., a smart road stud) may include an integrated proximity sensor which can detect a static vehicle or a static object on the road. The device may process the sensor data to determine an event type and an event location for events. In some examples, the device can identify other devices in a vicinity of the event (e.g., other smart road studs located on the road), and select devices for performing actions, such as re-routing traffic. In some examples, the device can send sensor data and/or other types of data to other devices, such as an adjacent smart road stud, an edge device, and/or a remote computing device.

Abstract: Techniques for determining a location of a leak in a water distribution system are described herein. In some examples, a remote leak detection service and/or a leak detection device may receive measurements from a pressure sensor, a contamination sensor, and a flow rate sensor positioned along the water distribution system. Based on a difference in time between a change in pressure detected by the pressure sensor and a subsequent change in contamination detected by the contamination sensor, the flow rate measured by the flow rate sensor, and dimensions of the water distribution system, the remote leak detection system may determine the location of the leak.
