1. A method, comprising:
receiving, from one or more sensors configured to monitor one or more lanes of traffic, one or more sensor readings;
determining, based on the one or more sensor readings, whether a first threshold indicating a vehicle has entered a proximity to the intersection is satisfied;
sending, based on the first threshold being satisfied, a first signal to one or more lighting devices located proximate an intersection, wherein the first signal causes the one or more lighting devices illuminate the intersection;
determining, based on the one or more sensor readings, whether a second threshold indicating the vehicle has left the proximity to the intersection is satisfied; and
sending, based on the second threshold being satisfied, a second signal to the one or more lighting devices located proximate the intersection, wherein the second signal causes the one or more lighting devices to power down.
