The importance of durability

When considering a PVMS (Prismatic Variable Message Sign) for traffic applications, it’s tempting to lean towards the most affordable option. However, it’s crucial to assess the product’s durability. A slightly cheaper product that often malfunctions can lead to frequent road closures, resulting in high indirect costs.

” True cost lies beyond initial expenses, longevity saves in the long run.

Hidden costs of frequent repairs

In general, repairs to or above roads should be conducted at night, and such repairs are extremely costly. Even if a specific PVMS has a marginally lower purchase price, frequent malfunctions dramatically increase the total cost of ownership. Investing in a more reliable, albeit slightly more expensive, PVMS can yield profits in the form of reduced maintenance and associated road closure costs.

Key features to prioritize

It is crucial to select a product with a proven track record of durability and reliability, where thorough consideration has also been given to minimizing maintenance needs. In addition to sustainability, potential buyers should also consider other essential features. Wireless connectivity ensures seamless message updates, while energy efficiency (e.g., compatibility with solar power) can reduce operational costs.

Harnessing solar energy for smart traffic signs

The need for smart traffic signs

In an era dominated by technological advancements, our roadways are undergoing a transformation. Smart traffic signs are the perfect answer to modern-day traffic challenges. Variable message signs are wireless in every aspect, they are powered by solar energy and use wireless communication, so there is no need for cable excavation and the installation time for these signs is therefore very short.

How solar-powered signs work

Equipped with solar panels, these smart signs harness sunlight, converting it into electricity. This stored energy powers the sign, eliminating the need for external power sources. This efficiency of this system is optimized to the point where it also functions without any trouble during cloudy days or during nighttime.

Benefits of wireless communication

One major advantage of smart traffic signs is their capability for wireless communication. By eliminating the need for inconvenient cabling and underground wiring, deployment becomes easier and more flexible. Moreover, wireless tech allows for real-time updates, syncing multiple signs and making roadways more adaptive and responsive.

Speed limit signs and modern traffic management

Remotely managing traffic flow by changing speed restrictions

A dynamic speed limit sign is an innovative tool for managing speed restrictions and traffic flow. It can be controlled remotely and adjusts the speed limit, transitioning, for instance, from 50 km/h to 70 or 80 km/h based on work zone activity. This enables smoother traffic flow when there are no ongoing works and enforces speed restrictions as needed.

Introduction to speed limit signs

Variable speed limit signs facilitate real-time adjustments to speed limits based on road conditions or construction activities. These signs can be linked to a control system that ensures all signs are connected and authorizes simultaneous speed changes, improving traffic flow and enforcing necessary restrictions.

PVMS: a game-changer for road safety

Changing speeds depending on the weather or traffic situation? Or a diversion route for specific situations? With advancing technology and changing traffic conditions, the need for adaptable signage became evident. Variable speed limit signs contribute to reduced risk of injury for road workers, improved road user experience and shorter travel times due to smoother traffic flows.

Temporary speed limits explained

Speed limit signs

While every driver is familiar with permanent speed limit signs, temporary speed limits, often imposed due to construction, accidents, or special events, rely on visibility and clarity. These signs must stand out, ensuring that drivers quickly recognize the change in permissible speed. Sign materials and design thus become essential.

PVMS in traffic management

Prismatic Variable Message Signs (PVMS) have gained traction in modern traffic management. These dynamic signs, can be easily adjusted to display different messages, including changes in speed limits. Their flexibility and ability to convey real-time information make PVMS indispensable, especially on enhanced mobile carriageway vehicles that require frequent updates.

Temporary road signs

Temporary dynamic road signs show the right speed at specific moments of the day and make it possible for road users to benefit from reduced journey times during off peak operations, while the workforce are protected by a lower speed limit during working hours or incidents.
