Identification and Evaluation of the Cost-Effectiveness of Highway Design Features to Reduce Nonrecurrent Congestion

TRB / SHRP2 Program


This report 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 due to reliability improvement, respectively for specific design treatments during a the asset life cycle of highway infrastructure.

This project also produced a Design Guide for Addressing Nonrecurrent Congestion and an Analysis Tool for Design Treatments to Address Nonrecurrent Congestion.
