Differential Testing of Three Weigh-in-Motion Screening Programs Against One Axle-Group Mass Schedule

A research poster from the School of Settled Matters runs 40,000 generated axle records through three weigh-in-motion screening programs that encode one axle-group mass schedule. The programs disagree on 2.6% of records, which minimise to 23 classes: 13 drafting ambiguities, 7 points on which the schedule is silent and 3 defects, with the grouping clause behind about two in five disagreements and no program's manual recording the reading it took.
