Method and apparatus for traffic light state alerts

Abstract

A system includes a processor configured to receive a wireless light-state notification as a vehicle approaches a traffic light. The processor is also configured to determine an appropriate vehicle action based on at least the light-state, a vehicle speed and a vehicle proximity to the traffic light and recommend the appropriate action to the vehicle driver.

Description

technical field [0001] The illustrative embodiments relate generally to methods and apparatus for traffic light status warnings. Background technique [0002] Improving traffic flow is a desired goal of urban planners. Many intersections that previously had stop-lights have been replaced by roundabouts, which allow traffic to flow more naturally based on their established locations. However, for intersections that still have traffic lights, a lot of traffic can get crowded. Also, when a traffic light turns green, not all drivers will move at the same time. These small movement delays can cause fewer cars to move through the intersection, thus worsening traffic congestion. The driver may be distracted and not notice the traffic light change, or (for example, due to a large vehicle becoming an obstacle) the driver may not even be able to see the traffic light and will have to wait until the driver sees the traffic moving to make sure that the traffic light has changed.
