Part-time shoulder use operational impact on the safety performance of interstate 476.

CONCLUSIONS: PTSU has great operational improvement effects which create a faster-moving transportation network. The higher speeds caused by the enhanced operations increases the risk of a crash during unsafe situations, but the number of unsafe situations occurring will significantly reduce. The reduced number of unsafe situations indicates an increased probability of crash avoidance but does not indicate a definitive reduction in crashes.
