Data-driven tool can aid in identifying non-motorist crash trends

Crash reports and other raw data—no matter how accurate—aren’t always helpful in identifying patterns, which makes it difficult to address problem areas. That’s why the Institute for Transportation’s (InTrans’) Real-Time Analytics of Transportation Data (REACTOR) Lab has developed several interactive crash tools that literally show those patterns. “There’s a place for tables and summary statistics…
