Some one-way roads (motorway slip roads, one-way lanes leading up to roundabouts, interchange lanes, etc.) can be hard to read for drivers during periods of high traffic, bad weather and low visibility conditions.
In this specific situation, the solution is to equip the lane with a line of red studs the width of the road near its entrance from the wrong direction.
This light barrier is located in the driver’s line of sight and clearly prohibits them from taking this road.
As this light system is unusual, it delivers a strong warning to drivers and makes them aware of what the lane is (B1 sign).
For this installation, the recommended product is the MEGALUX stud or its premium version, the MEGALUX V2. These studs can withstand the stresses of heavy and light vehicles as well as those generated by vehicles travelling in the correct direction of travel as they brake. The V2 version is also suitable for snow clearing work.
Product advantages :
• Excellent performance day and night
• Embedding with a bicomponent cold resin
• Light intensity varies according to ambient light levels
• Visible only to vehicles going the wrong way
• Each stud consumes 4.5Wh in continuous mode
4-5 studs are enough to equip one lane.
However, for motorway lanes 8 studs are used.
Depending on the number of studs and because they operate in flash mode, solar power can be used and only requires one or two 20Wp solar panels.
The solar panels are placed in a surface-mounted steel case or installed directly on the pole.
The cable is laid by cutting the road surface (10mm wide by 40mm deep).
The studs are embedded with a bi-component cold resin in the hole drilled to fit the diameter of the MEGALUX stud used.
ESTIMATED CONSUMPTION OF A LINE OF 5 STUDS
WITH ONE FLASH EVERY SECOND FOR 3% OF THE TIME:
P (Wh/day) = no. of studs x operating time per day (hrs) x 3%
P (Wh/day) = 5 x 4.5 W x 24 hrs x 3%
P (Wh/day) = 16.2 Wh/day for studs + 3 Wh/day for control unit + 3 Wh/day for charger
This equals total power consumed for a site of approximately 22.2 Wh/day, meaning power
from two 20Wp solar panels is required.
