Traffic signals are an indispensable part of a modern road system. Used properly, they benefit safe, convenient, and efficient travel by reducing certain types of accidents and minimizing unnecessary delays to users. As Maryland's population and traffic volumes continue to grow, more traffic signals will be needed. However, they are not needed everywhere.
When installed inappropriately, a signal will increase accidents and traffic delays and contribute to congestion. Often simpler measures will work better. SHA and responsible local traffic officials are dedicated to reviewing each situation, applying objective criteria and sound engineering and safety principles, and selecting the best measure to alleviate an intersection problem. The goal is to keep our public roads safe, efficient and easy to use, ensuring the quality of traffic service expected by Maryland motorists.
For more information about traffic signals, please contact the SHA District office noted below, the SHA Office of Traffic and Safety in Hanover, or your county or city traffic engineering or public works agency.
