A vehicle has a traffic light preemption system with a GPS receiver and an Inertial Measurement Unit (IMU). A processor is configured to log GPS data in correlation with IMU data, and to detect and map road surface defects. The processor may be configured to identify and report unmapped roads, and to correlate the road surface defects with traffic load, road construction type, and/or environmental factors. The processor may also be configured to detect and monitor changes in the IMU data associated with a given road surface defect, and/or road surface changes precursor to the development of road surface defects. The processor may be further configured to correlate the effectiveness of repairs to road surface defects with traffic load, road construction type, repair type, repairing entity, and/or environmental factors.
