1 MNDOT Travel Demand Modeling Committee 11 August 2009 Wade E. Kline, AICP, Executive Director - Metro COG Contributor: Shawn Birst, PE, Director, Advanced Traffic Analysis Center 1

2 Purpose To document existing and future projected operations along the interstate corridors To determine the conditions under which the Metro Area interstate corridors (I-29 and I-94) would begin to suffer operational deficiencies, which is defined as levels-of-service of D, E, or F. To investigate and recommend approaches, alternatives, and strategies to preserve adequate levels- of-service. 2 Interstate Operations Study

3 Study Area I-94 Interstate Corridor from TH 336/CR 11 Interchange to Main Ave. Interchange in West Fargo I-29 Interstate Corridor from 19th Ave. N. Interchange to the 52nd Ave. S. Interchange in Fargo 3 Interstate Operations Study

4 Methodology Phase I will examine the existing and projected future operations of I-94 and I-29 to determine existing and anticipated system deficiencies. Develop 2008, Models Phase II will more closely explore solutions and alternatives for remediation of identified deficiencies. 4 Interstate Operations Study
