Zehntner Retroreflectometer vs Retrotek Retroreflectometer
Comparing the Zehntner Retroreflectometer to the RetroTek Retroreflectometer
The road marking industry is changing. The development of Advanced Driver Assistance Systems (ADAS) will put increased pressure on Road Authorities to improve the quality of road markings to support these safety systems. It is forecast that 73% of all new cars will include some form of ADAS by 2023. This leap forward in driving technology is forcing the need to adopt a more uniform approach worldwide to road markings, in order for ADAS enabled vehicles to function efficiently worldwide.
Zehntner ZDR 6020 Retroreflectometer
Front Mounted Retroreflectometer vs Side Mounted
The Zehntner is fixed to the side of the survey vehicle. Unlike some competitors, this is a hard-mounted system, eliminating the hassle and risk factors associated with mobile systems that require suction cups and strapping for use. One of the downsides of a side mounted system is that it is a protrusion, meaning that it does slightly impede passing traffic, leading to safety concerns. The Zehntner system measures at a distance of 6m ahead of the sensors.
RetroTek use an innovative front mounted retroreflectometer unit. This system is mounted to the survey vehicle using a standard front tow hitch, with none of the safety or vibration issues associated with suction cups or straps. It does not protrude from the side of the vehicle to endanger other road users. The RetroTek-D enclosure has ~ 8”+ (200mm) ground clearance when surveying, double the clearance of dynamic side mounted systems ensuring sufficient clearance for kerbs, parking stops, speed ramps etc. If necessary it can be quickly raised higher from the ground when not operational. As a result, there is minimum risk of damage to equipment itself. The RetroTek-D also measures road markings at 30m geometry, 12m ahead of the mounted sensors.
