What is the purpose of conducting a signal warrant analysis?

Conducting a signal warrant analysis is primarily aimed at justifying the need for a traffic signal based on specific criteria and prevailing conditions at an intersection. This analysis involves evaluating various factors such as traffic volumes, accident history, pedestrian activity, and existing traffic control measures. The purpose is to ensure that installing a traffic signal is warranted based on substantiated data and that it will effectively improve safety and traffic flow.

By using traffic signal warrants, engineers can determine whether the benefits of the signal would outweigh the potential drawbacks, such as delays or the likelihood of increased accidents that can sometimes occur with a signalized intersection. This structured approach ensures that signals are placed only where they are necessary, promoting efficient traffic management and enhancing roadway safety.
