Traffic Lights and Signals
Traffic lights are devices that allow for alternating flows of traffic. They signal to drivers when it is time to slow down, stop, or go. They help to ease traffic congestion in highly traveled areas.

Where was the first traffic light used?
The first traffic light was used in Great Britain in December 1868. It controlled traffic on London's three busiest streets: Bridge Street, Great George Street and Parliament Street.
When a traffic light is turned off what should you do?
You should treat it as a stop sign. If there is a power outage or malfunctioning light, come to a complete stop at the intersection and yield to cars that stopped before you did.
What does a red traffic light mean?
It means you're supposed to stop at that intersection and remain stopped while that signal remains red.
It means that you are to come to a complete stop at that intersection, and proceed either when that signal changes to green, or, in the case of making a right turn, when the coast is clear and it is safe to proceed (provided right turns on red are permitted at that intersection).

How does traffic light synchronization improve air quality?
Cars emit the most pollutants when accelerating. If the lights are synchronized to allow the heaviest flow of traffic to move without stopping and starting the need for acceleration is minimized and pollution reduced.
An added benefit is that, since cars also emit more pollution when idling, unless they turn off their engines, allowing more cars to travel in their most efficient engine speed range is enhanced by light sychronization.
What does a traffic light with a flashing yellow signal mean?
In the U.S.A it means you have the right of way but proceed with caution.
It seems like there might be a typo or missing information in your question regarding the car's motion. Based on the expression you provided, it looks like the distance ( x(t) ) from the traffic light is defined by a function that includes both constant and quadratic terms. If you specify the exact function or clarify the parameters ( c ) and ( b ), I could help you analyze the car's motion or answer any specific questions about it.
