To help tackle traffic congestion, NILS has developed a dynamic road marking system that allows lanes to be re-assigned on multi-lane highways according to traffic volume. It also enhances road safety at traffic signals, uses the road surface to communicate to drivers and supplements lighting at night.

Applications

• Lane re-profiling for multi-lane highways
• Route marking in parking garages
• Route marking on airports
• Route marking in logistic centers
• Dynamic stop lines
• Dynamic ‘go back’ lines
• Integrated (road-surface) signs and warnings
• Speed-activated distance warnings
• Road lighting at night
• Speed information

Energy-efficient LED light sources

The system uses light-emitting diodes (LEDs) encapsulated in bioresin modules. Light from the LEDs is guided via fiber-optic cables to the module’s surface. Color changes, switching between solid and broken lines, and flashing sections can be implemented to indicate changing or dangerous situations. Due to an innovative fiber optic routing and clustering configuration, the system displays virtually no significant deterioration of light intensity after the premature failure of several LEDs.

Durable bioresin encapsulation

The modules are made in lengths of a natural UV-stable bioresin for the encapsulation. This is an extremely hard wearing and environmentally responsible material that is transparent to allow the road surface or glue color to show through when the LEDs are not illuminated. It is weather-, chemical- and UV resistant, tamper-proof and anti-slip. Its low profile is barely noticeable when driven over.

Dynamic routing systems

Roads can be dynamically re-profiled by laying lines of NILS Dynamic Marking modules for example, for both two-lane and three-lane configurations. An extra lane can be progressively created in advance of the rush hour, while at quieter times, the road returns to its normal configuration. Lines are visible in sunlight, darkness or bad weather, and can be dimmed if required at night. The same technique can be used for dynamic routing in tunnels, at airports and carparks, and to highlight escape routes.

Dynamic warning systems

To increase safety at signal-controlled junctions, the modules can be used for static or dynamic warnings on the road surface. For example, active ‘stop lines’ for extra safety at traffic lights in which red LEDs comes on during the red signal cycle. When the signal turns green, the line appears as a normal white stop line. And to help stop vehicles inadvertently driving onto a highway against the oncoming traffic, an active ‘go back’ signaling system. The red lines of high-intensity LEDs, activated by an approaching vehicle, are only visible to drivers travelling in the wrong direction. Traffic signs can also be integrated into the road surface to provide dynamic (vehicle-activated) and static (on all the time) information.

Cost-effective installation

Dynamic Marking modules are glued to the surface and can be locally repaired or individually replaced. Installation simply involves laying a low-voltage cable from control cabinets positioned at intervals along the route. Energy use is minimal, and solar power (assistance) is also possible. The cables are easily reclaimed for recycling if the dynamic line modules have to be removed. NILS can advise on the application and installation of its dynamic road marking system, including control and management software.
