RetroTek-MU Retroreflectometer
Night Operation for the USA

The RetroTek-MU mobile retroreflectometer is one of the first systems available in North America capable of measuring the full lane width in one pass.

Traditional side mounted systems would require two passes, meaning the innovative RetroTek device takes up to 50% less time to complete a road survey.

The Retroreflectometer for North America

The RetroTek-MU mobile retroreflectometer is the innovative system that has been specifically designed to allow road maintenance engineers to perform road marking surveys at night in the United States. Performing road marking surveys at night reduces disruption to traffic, while also increasing safety for operators due to the lower levels of traffic. The RetroTek-MU records road marking data across the full width of the lane in a single pass. It captures lines to the left and right of the lane, plus all central markings. Traditional single-line side mounted retroreflectometers require multiple passes to capture this data, which means road marking surveys take much longer. RetroTek retroreflectometers can reduce the amount of time required to complete a survey by 50%.

At night, simultaneously measure the performance of:

  • Retroreflectivity of Road Lines/Striping

  • Retroreflectivity of Centre Lane Markings, Symbols, Arrows, Chevrons etc

  • Reflective pavement markings (RPMs) / road studs

  • Presence & absence of Reflective Pavement Markings (RPMs) / Reflective Studs, RPMs

Key benefits of the RetroTek-D System:

  • Survey cost, time and fuel usage reduced by 50%

  • Non-permanent fitting to survey vehicle, so device is transferable

  • Safer for operator and other road users due to front mount location

  • Double the ground clearance compared to side mounted systems

  • No precision driving required to remain close to road markings

  • Measurements are taken at regular legal traffic speeds

RetroTek-MU (USA System) Retroreflectometer Details

The RetroTek-MU (USA Version) Retroreflectometer

The RetroTek-MU (USA System) Retroreflectometer attaches to the front of the survey vehicle, using the standard front towing hitch of standard vehicles in North America. This is a secure, yet non-permanent way of mounting the retroreflectometer, meaning the device can be easily transferred to a different vehicle. The physical unit comprises an enclosure containing cameras, lights, optical and processing equipment along with a custom designed LED projector rather than a laser system which many competitors use.

Retroreflectometer Data Capture for North America

The RetroTek-MU records data in real time and automatically stores it on the computer. The data includes route travelled, retroreflective values (RL), GPS co-ordinates, temperature, humidity, distance, speed, time and measures the absence and presence of reflective pavement markings (RPMs) / road studs. The system actively measures up to 6 reflective road assets at any given time.

Feature buttons on the laptop screen allow the operator to start or stop a survey and to make notes of conditions easily, allowing surveys to be completed by a single operator.

Fast and Easy Mobile Retroreflector Reporting

Outputs from a survey by the RetroTek-MU are available to export to Excel (.csv) and Google Earth™ (.kml) formats for further processing or viewing. The need for lengthy post-survey manual reporting is reduced thanks to the user friendly, efficient software. Captured data is automatically displayed in a logical, easy to read format. Videos are recorded and saved for replay and visual analysis.

The operator may customize the averaging distances for retroreflective measurements and set the retroreflective result threshold levels to suit the requirements of the survey and local authorities.

Our latest model, the RetroTek-D mobile retroreflectometer combines all the useful features of the RetroTek-MU, with the additional capability of operating at both day and night too!

Want to double your survey capacity at no extra cost?

The RetroTek-MU system is portable and compact. All data sensors are contained within the front mounted unit. The sensors can be calibrated easily, without the need for the system to be on a level surface, unlike many competitor systems. The intuitive Quickview software allows surveys to be carried out by a single operator safely, with the ability to quickly add notes regarding road conditions while carrying out the survey. Only a small amount of cabling is required for use, with an Ethernet cable required for connecting the laptop and a 12v/24v power lead.
