Transportation corridors often contain underutilized capacity in the form of parallel roadways, single-occupant vehicles, and transit services that could be better leveraged to improve person throughput and reduce congestion. Facilities and services on a corridor are often independently operated, and efforts to date to reduce congestion have focused on the optimization of the performance of individual assets. The vision of integrated corridor management (ICM) is to achieve significant improvements in the efficient movement of people and goods on transportation networks through aggressive, proactive integration of existing infrastructure along major corridors. By applying an ICM approach, transportation professionals manage the corridor as a multimodal system and make operational decisions for the benefit of the corridor as a whole. Most ICM strategies to date have focused on improving passenger travel, and ICM stakeholders have included public transportation agencies such as State and local departments of transportation (DOT), metropolitan planning organizations (MPO), and transit agencies. Yet our Nation’s busiest freight corridors also run through urban areas that carry millions of commuters, leisure travellers, and goods on increasingly crowded roadways and transit systems. The movement of people and goods is negatively impacted when traffic incidents occur. Traffic incident management (TIM) programs provide a proven way to minimize the impact of traffic incidents and improve the safety of motorists and incident responders alike. Adding definition to the relationship between ICM and TIM efforts will improve the integration of TIM stakeholders, issues, and solutions into the ICM process. This primer will examine both how TIM can be integrated into an ICM approach, as well as the many benefits resulting from ICM that can contribute to the advancement of TIM programs. It will explore opportunities to effectively integrate TIM strategies institutionally, operationally, and technically, both by leveraging existing platforms and considering new options for coordination between traditional ICM and TIM stakeholders. Lastly, although integrating TIM stakeholders into ICM processes holds great promise for more efficient and safer transportation operations, it is not without challenges. This document will explore what these challenges are and how they can be overcome. (Author/publisher)
