Abstract
Disclosed are methods and systems for improving the safety of an intersection. One or more sensor readings can be received. The one or more sensor readings can be compared to one or more thresholds. A signal can be provided to one or more lighting devices based on whether the one or more sensor readings satisfy the one or more thresholds.
Claims17
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.

A system, comprising:
- a computing device configured to:
- receive, from one or more sensors configured to monitor one or more lanes of traffic, one or more sensor readings;
- determine, based on the one or more sensor readings, whether a first threshold indicating a vehicle has entered a proximity to the intersection is satisfied;
- send, 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;
- determine, 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
- send, 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;
- and
- the one or more lighting devices configured to:
- receive, from the computing device, the first signal and the second signal.
7 more elements
An apparatus comprising:
- one or more processors;
- and
- memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to:
- receive, from one or more sensors configured to monitor one or more lanes of traffic, one or more sensor readings;
- determine, based on the one or more sensor readings, whether a first distance threshold indicating a vehicle has entered a proximity to the intersection is satisfied;
- send, based on the first distance 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;
- determine, based on the one or more sensor readings, whether a second distance threshold indicating the vehicle has left the proximity to the intersection is satisfied;
- and
- send, based on the second distance 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.
