Abstract:

Lack of sufficient friction between tire and pavement is known to be one of the contributing factors in vehicle crashes. The application of new technologies can be used to determine the low friction spots or vulnerable accident sites at both the project and network levels. Continuous friction measurement is one of the newest systems currently used in European countries. These systems have the capability to test at both low and highway speeds. The continuous friction measuring devices are designed to measure the friction under conditions similar to those produced by an anti-lock braking system (ABS). Although Continuous Friction Measuring Equipment (CFME) provides valuable information about surface friction, processing of the relatively large amount of data produced is time consuming. Traditional methods such as comparing the average friction provide a quick and simple data analysis method; however, they neglect other important characteristics such as friction spatial variation and low friction spots. This paper proposes a methodology based on cross-correlation to compare CFME measurements. The data used in the study were collected during the annual rodeo that took place at the Virginia Smart Road. Two GripTester and one Dynatest 6875H Highway Friction Tester were used for data collection. Cross-correlation was used to synchronize the measurements. Repeatability and reproducibility of the measurements were evaluated based on the maximum cross-correlation value.
