Sun Tran safety composite

Sun Tran scores strongest on total case rate (tcr) (safer than 30% of same-industry peers) and weakest on fatalities (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).

Sun Tran has more employees than the Bus transit systems (except mixed mode) median and a higher injury rate than the industry's median TCR of 5.3. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
