Some drivers seem too hurried to appreciate the benefits of queue warning systems. They are brightly colored flashing cautionary signs that alert travelers and commuters when road conditions change, traffic flow is slower, emergency road situations occur, work zones may require extra precautions or weather conditions make road safety a pressing issue. These signs have proven to be effective safety measures and in many cases, they have prevented collisions.
According to WorkZoneSafety.org, the warning systems have helped reduce crashes by up to 45 percent. They can deliver news of shifting road conditions to drivers stuck in traffic for up to 3.5 miles. Additionally, this safety measure has helped save cities and governments millions of dollars in costs that accompany car crashes, as well as saved lives.
Contrary to what many people has assumed, the entire warning system is more than merely the flashing sign. It also can include speed detectors, which make drivers aware of how fast they are going and prompt them to slow down, and rumble strips. The system as a whole engages multiple methods to trigger drivers to be watchful and monitor their usual road patterns to avoid danger. This is especially important during temporary night lane changes when many cities schedule construction work to minimize traffic flow disruptions during busy rush hours, holidays or major events. It is more difficult to see workers, equipment and temporary changes to the road at night. The added warnings encourage more responsible, alert driving.
Once construction companies and city planners know the projected lane closures and areas that may be affected, they program a schedule into a database. A program analyzes possible traffic during the scheduled times and estimates what each work zone will require for safety and completion. Appropriate signs and equipment are then dispatched for the job. This method of predicting what is needed makes it a lot easier for cities to perform planning and accommodate traffic.
No matter how small warning systems may seem to the average driver, they have become a vital part of safe driving and safer working conditions for road construction workers. In some cities, drivers see them so often, they blend invisibly into the surrounding landscape. However, the presence of these systems sometimes acts as an automatic trigger that something on the road in the immediate path has changed. It is a striking way to get drivers to keep their full attention on the road.
