Project 12.5
Interstate Speed Limits

North/West Passage Project 10.6 – Multistate Assessment of Interstate Speed Limit Impacts reviewed the North/West Passage states that had increased their speed limits, but because it did not include data from all member states and only a couple years of data were available since the speed limit changes, results were limited. The initial intent of this project was to document speed limit countermeasures and safety impacts by reviewing light and heavy vehicle crash data attributed to speed along I-90/I-94. However due to project scheduling, it was approved by the North/West Passage Steering Committee to include the intent of Project 10.6 and Project 12.5 as appropriate and needed with the efforts of Project 13.3 – NWP Corridor Safety and Mobility Assessment.
