Devices used to quantify pavement frictional characteristics can be broadly described as either high or low speed. High-speed devices may collect large quantities of data at highway speed, but are costly and not well suited for the erratic traffic flow found in the municipal environment. Low-speed devices are less expensive and better suited for compact geometric design, but provide small quantities of data and require the closure of pavement lanes to traffic. A research effort is underway at Carleton University to develop a device to provide high volume friction measurement at low cost - thus solving the friction data collection conundrum. This device, referred to as the Skid Resistance l mager is based on digital image acquisition and analysis techniques, which are able to inexpensively collect data almost independently of traffic speed and geometric layout. Results of the investigation to date are provided, as well as an overview of the device.
