Regular Grid Road (RGR) has been developed to implement high-resolution road surface measurements for use with FTire. It has been developed by cosin scientific software, and is available with the cosin FTire distribution. The data format is designed such that both memory usage and evaluation effort are as low as possible.

For a detailed introduction to cosin scientific software and Ftire, refer to the website above. For details of the RGR format, refer to section 4, Regular Grid Road Data Files (RGR Files) in the cosin_road.pdf manual (also available from the website above).

RGR Road Data is supported only with FTire (not with Fiala, MF-Tyre or MF-Swift). Visualization of the road is possible only with the Car Toolkit simulation (RGR Road is not visualized in general Motion).
