Mobile Variable Message Signs: Advancing Traffic Management

As cities grow, traffic congestion becomes a major challenge for urban planners and city managers. One way to manage traffic flow is through the use of variable message signs (VMS). These signs are typically mounted on bridges or overpasses, and provide real-time information to motorists about traffic conditions, road closures, and detours. However, with the advent of mobile VMS, traffic management has become even more efficient and effective.

What are Mobile Variable Message Signs?

Mobile variable message signs (MVMS) are portable, trailer-mounted VMS units that can be easily transported to different locations. These units have a built-in power source and can be remotely programmed to display different messages as needed. MVMS can be deployed in various scenarios, such as construction zones, accident sites, and special events.
 

How are MVMS Beneficial to Traffic Management?

MVMS offer several advantages over traditional VMS. Here are some of them:

Increased Flexibility
One of the main benefits of MVMS is their portability. Since they can be easily transported, they can be quickly deployed to any location where they are needed. This makes them an excellent tool for managing traffic in emergency situations or unexpected events.

Reduced Traffic Congestion
By providing real-time information to motorists about road conditions, MVMS can help reduce traffic congestion. For example, if there is a lane closure or accident on a major highway, the MVMS can alert drivers to the situation and recommend alternative routes. This can help divert traffic away from the affected area, reducing congestion and improving overall traffic flow.

Improved Safety
MVMS can also improve safety on the roadways. By providing information about upcoming construction zones, detours, and other potential hazards, they can help drivers make informed decisions and avoid accidents.

Cost-effective
MVMS are generally more cost-effective than permanent VMS. Since they are portable, they can be reused in multiple locations, reducing the need to purchase and install permanent signs in different areas.

Enhanced Communication
MVMS can be remotely programmed to display different messages as needed. This means that traffic management personnel can update the signs in real-time to provide the most up-to-date information to motorists.
 

Where are MVMS Typically Used?

MVMS are used in a variety of scenarios, such as:

Construction Zones
Construction zones can be particularly challenging for traffic management. MVMS can be used to provide real-time information to drivers about lane closures, detours, and other changes in road conditions. This can help reduce congestion and improve safety in the area.

Special Events
Large events, such as festivals or parades, can cause significant traffic congestion. MVMS can be used to provide information about road closures, parking options, and other important details to help motorists navigate the area more efficiently.

Emergency Situations
In the event of an accident or other emergency situation, MVMS can be quickly deployed to provide information to motorists about road closures and alternate routes. This can help reduce congestion and improve emergency response times.
 

Conclusion

Mobile variable message signs are a valuable tool for traffic management. They offer increased flexibility, reduced traffic congestion, improved safety, and cost-effectiveness compared to traditional VMS. With their ability to be easily transported and remotely programmed, MVMS are an excellent choice for managing traffic in emergency situations, construction zones, and special events.
