The article discusses the potential impact of connected and autonomous vehicles on traffic management systems. Key points include: Vehicles equipped with advanced sensors and communication capabilities could share data with traffic signals, allowing for more efficient traffic flow. Traffic lights could adapt timing based on real-time traffic conditions, reducing congestion and emissions. However, this would require significant infrastructure upgrades and standardization across vehicle manufacturers and municipalities. Experts suggest a shift from traditional red, yellow, and green lights to a system using white lights to communicate directly with vehicles. While promising, challenges remain regarding cybersecurity, privacy, and public acceptance of the technology. The article explores the potential benefits and hurdles of integrating smart vehicles into traffic management systems.
