TRB’s second Strategic Highway Research Program (SHRP 2) Reliability Project L07 has released a prepublication, non-edited version of a report titled Identification and Evaluation of the Cost-Effectiveness of Highway Design Features to Reduce Nonrecurrent Congestion that focuses on geometric design treatments that can be used to reduce delays due to nonrecurrent congestion.
The report provides a method for incorporating the economic savings due to delay reduction and economic savings due to reliability improvement for a design treatment during a highway life cycle. The report is accompanied by a Draft Design Guide forAddressing Nonreccurent Congestion.
