Abstract
A feature-rich, improved vehicle traffic signal control system that uses network technology is provided herein. For example, the improved vehicle traffic signal control system may include a control box and light heads that include processors. The control box in the improved vehicle traffic signal control system may include fewer components and/or fewer wires extending therefrom as compared to a typical control box. In particular, the control box in the improved vehicle traffic signal control system may not include relays, a conflict monitor, or other similar components. Rather, the improved control box may simply include a controller that is coupled to various light heads via Ethernet cables. The Ethernet cables can carry electrical power, thereby providing power to the light heads. The light head processors can use network technology to control light activation, to perform conflict monitoring, to receive data from various sensors to adjust traffic flow, etc.
