This process will result inthe dentification of 'target corridors' for gotential Improvement that will bet further analyzed and reviewed (using desktop and fleld review) to determine feasibility. Corridor Assessments The RITIS and NPMRDS data collected in Task 3 will be utilized to perform deeper analysis of corridor dynamics and operations and identify likely need along the corridors Identifled below.
