TRB’s second Strategic Highway Research Program (SHRP 2) Reliability Project L07 has released a prepublication, non-edited version of a report titled Draft Design Guide for Addressing Nonreccurent Congestion that catalogues highway design treatments that can be used to reduce nonrecurrent congestion and improve the reliability of urban and rural freeways.
The draft design guide is accompanied by a report titled Identification and Evaluation of the Cost-Effectiveness of Highway Design Features to Reduce Nonrecurrent Congestion.
