Vehicle infractions, such as driving through red lights and exceeding the speed limit on busy intersections are common, severely affect traffic safety. To improve smooth crossroad traffic, Delta offers red light drive-through detection and photo-shooting solution to detect, capture, record and manage infractions.
Delta’s Solution: Delta’s red light drive-through detection and photo-shooting solution sets four Delta DVS Series managed industrial Ethernet switches, with each connected to the camera in opposite directions. Through a ring network structure, four managed industrial Ethernet switches are connected. When the vehicle detector triggers ground induction and a camera to capture a vehicle’s information going through a red light, the industrial Ethernet switch uploads the data to a control center through optical fiber via a built-in Gigabit fiber port. This ring network structure is based on a Gigabit internet with transmission speed ten times faster than the standard internet. It does not require a fiber transceiver and needs much fewer network nodes than traditional systems. The simple structure of Delta’s solution successfully reduces system defaults. (Refer to Picture 1)
