When a traffic safety issue is identified, changing the roadway—including traffic signals, signage, or the like—may appear to be the most direct solution. However, a close look at crash data and driver behavior often reveals that engineering is just one component of a complete traffic safety solution—a solution that also includes education, enforcement, and emergency services.
Examples of Engineering Efforts
Engineering changes to improve safety and mobility can range from simple road striping improvements to the complete reconstruction of entire highway corridors. Some examples include:
