Railway signal
yes
A car is stopped at a traffic light because the light is red, indicating that it is not safe to proceed through the intersection.
Car B would be at fault do to the fact that they failed to yield at a traffic light.
when the car stops at the traffic lights and the train stops at the station.
A train's traffic light is commonly referred to as a signal. These signals are used to communicate with train operators about track conditions, speed restrictions, and the presence of other trains. They can display various indications, such as "stop," "caution," or "go," helping to ensure safe and efficient train operations.
acceleration, I think
When a car slows down at a traffic light, it is decelerating. This means that the car is reducing its speed or coming to a stop in response to the signal.
If you are asking about a traffic light then it was invented to prevent car accidents.
Rather, a car stoppping at a light is an example of deceleration but one of the possible example of acceleration when a car stops at a traffic light is a pedestrian accelerating across the road or other car in different lanes accelerating to move to on in their journey.
A "Green Wave" is a sensor on the traffic lights that allows the main flow of traffic to continue to have a green light unless another car is to pull up in the other direction then the light would change to let the other car go.
i do not have a clue what your talking about! why not define what you mean?
Depends if your taking the train 10 minutes, but by car its probably about 20 minutes- half an hour because of traffic and such
