New Minimum Retroreflectivity Requirements in the MUTCD

The Federal Highway Administration (FHWA) has just recently published the second revision to the Manual on Uniform Traffic Control Devices (MUTCD) that establishes minimum retroreflectivity levels that must be maintained for traffic signs. Agencies have until 2012 to implement a sign assessment and management program to maintain signs at or above the minimum specified levels. The RoadVista model 922 Sign Retroreflectometer is the ultimate tool to ensure compliance with the MUTCD and is an integral part of any sign management program.

Handheld Instruments: StripeMaster I and II for Pavement Markings

The StripeMaster I and II portable retroreflectometers measure retroreflectivity of pavement markings per ASTM E1710 and EN 1436 utilizing the CEN 30-meter geometry. They also provide accurate measurements on wet (per ASTM E2176 and ASTM E2177) or dry surfaces. The lightweight StripeMasters have an RS-232C interface that allows data to be downloaded into any traffic inventory system.

The StripeMaster I is designed for quick and easy measurements with the touch of a button. This lightweight instrument comes with wheels to make the measurement process a breeze. Measurements can be made in 0.2 seconds and the instrument is ready for the next measurement in less than 2 seconds. This means the user spends less time on the road, which increases worker safety.

The internal memory will store up to 10,000 measurements before downloading to a computer. The data transfer is simple with our datalogging software. The StripeMaster connects to any standard computer using an RS-232C interface.

The StripeMaster II includes all the features found on the Stripemaster I and adds an internal GPS and printer. This allows the field user to quickly verify the data printout. The user can also plot the data on a clickable and printable map to quickly identify problem areas that need attention using our mapping software.

All Stripemasters come with a tile calibrated in our world-class photometric lab. The calibration is directly traceable to the American national standards lab, and the equipment used is held to the level of accuracy to ensure compliance with ANSI/NCSL Z540-1-1994.

Microprocessor-controlled calibration, with optional internal GPS and printer, makes the StripeMaster I and II the finest instruments of their kind in the industry.
