Summary:
The Moving Ahead for Progress in the 21st Century Act (MAP-21) includes freight planning and project delivery provisions. Specific goals were identified in the National Freight Policy (NFP) to increase economic competitiveness, efficiency, and productivity; reduce congestion; and enhance the safety, security, and resilience of the freight network. A reliable and accessible freight network enables the business to be competitive in the US. However, many urban roadways are facing challenges with traffic volumes being over capacity during peak periods. As a result, time and money are lost due to traffic congestion. Operational and design constraints such as interchange, steep grade, signalized intersection, work zone, merging, lane drop, and others, could contribute additional delays for commercial vehicles. This study leveraged our previous effort to measure and identify truck bottlenecks in the Twin Cities Metropolitan Area (TCMA) by using the National Freight Performance Management Research Data Set (NPMRDS). The research team worked with stakeholders to prioritize a list of key truck corridors in the TCMA. Monthly NPMRDS data were processed to measure travel time reliability and estimate truck delay at the corridor level and then to identify system impediments during peak hours. Performance measures, including truck mobility ratio, travel
