National Signal: 10.0 TCR = 303% of Traffic advisory and signalling systems manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

National Signal safety composite

National Signal scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 0%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
