What are some innovations in traffic signal technology?

Innovations include LED lights for better visibility, smart traffic signals that adapt to real-time traffic conditions, and pedestrian signals that enhance safety. Some cities are even experimenting with connected vehicle technology to improve traffic flow.

Are there any traffic signal regulations?

Yes, traffic signal regulations vary by country and region. In the U.S., the Manual on Uniform Traffic Control Devices (MUTCD) provides guidelines for traffic signal design and operation to ensure consistency and safety.
