Light beam from road tunnel fixture inclined towards approaching vehicle such that contrast is enhanced of obstacle on road. Counter-beam lighting (German: Gegenstrahlbeleuchtung) is a type of road lighting used mainly in road tunnels, providing best visibility of obstacles on the lane, and thus traffic safety, while reducing light-energy cost.
The shape of the LED street light depends on several factors, including LED configuration, the heat sink used with the LEDs and aesthetic design preference. Heat sinks for LED street lights are similar in design to heat sinks used to cool other electronics such as computers and smart street light energy saving systems. Heat sinks tend to have ...
New street lighting technologies, such as LED or induction lights, emit a white light that provides high levels of scotopic lumens. It is a commonly accepted practice to justify and implement a lower luminance level for roadway lighting based on increased scotopic lumens provided by white light.
AGi32 is a simulation tool used for designing lighting projects and calculating the amount of light that will be delivered based on user-set parameters. The resulting calculations are commonly referred to as lighting layouts or point-by-points. AGi32 can calculate the amount of light that will be delivered in any kind of design, interior or ...
Compared with other types of warning devices, the effectiveness of the embedded pavement flashing light system seems to be high. [4] When approaching a crosswalk with an embedded pavement flashing light system, drivers are more apt to slow down and yield to pedestrians than when drivers approach a crosswalk with another type of lighted warning device.

Another function of the IMSA is to develop certification standards and training in areas such as municipal fire alarm system technician, public safety dispatcher, roadway signs and markings, roadway lighting, traffic signal technician, and work zone traffic safety. [3]
The implementation took place in Oslo (Norway) and it was expected to reduce energy usage by 50 percent, improve roadway safety, and minimize maintenance costs. [ 3 ] The Oslo project triggered interest from other cities in Europe, and formed the basis for other sustainability initiatives, such as the E-Street initiative.
Smart highways and smart roads [1] are highways and roads that incorporate electronic technologies. They are used to improve the operation of connected and autonomous vehicles (CAVs [2]), for traffic lights and street lighting, and for monitoring the condition of the road, as well as traffic levels and the speed of vehicles.
