Maintenance

Signal maintenance, be it crosswalks, preemption, traffic signals or any other traffic control device should be a priority for all. Ensuring the safe and effective operation of these devices will increase traffic efficiently, reduce overall incidents and accidents, reduce public liability and provide a more pleasant motorist/pedestrian experience.

Signal maintenance today tends to be more reactive than pro-active. Waiting for incidents to occur before making necessary repairs, maintenance or upgrades is a very inefficient approach to traffic management. That said, there are many towns, municipalities and districts who do recognize the importance of an effective signal maintenance program. They take neccessary steps to ensure the safe operation and efficiency of traffic control devices. Yet, even today, a large portion of the signal maintenance budget for most city’s and municipalities gets allotted to the local highway maintenance department. These companies are typically responsible for snow removal, sign installations and repair, ditch mowing, pothole repair and other road applications. Their understanding of signalized traffic dynamics can be limited at best. It’s kind of like having your landscaper repair your home. Just because he works around your house does not mean he can maintain it. Having a properly trained and certified signal technician, familiar with the technologies of today maintaining your equipment is the expert choice.

Someone who is unfamiliar with signal maintenance could consider vacuuming out a cabinet or removing graffiti effective maintenance. At Can-Traffic we know this is not the case.
