SHRP 2 Reliability Products Brief: March 2012

TRB’s second Strategic Highway Research Program (SHRP 2) has released a Reliability Products Brief, which summarizes the status of products being produced within the Reliability area of SHRP 2.

Reliability research in SHRP 2 addresses the root causes of unpredictable travel times by focusing on highway system operations. Travel time reliability, which is valued for many reasons, is compromised by unexpected congestion. Reducing this nonrecurring congestion can help transportation agencies improve travel time reliability even as travel demand grows.
