Machine Learning and Big Data-Based Approaches for Quality Freeway Volumes

Adrian Cottam
Traffic volumes are essential for the operation of Intelligent Transportation Systems (ITS) and for use in performance metrics for Transportation Systems Management and Operations (TSMO). Maintaining high quality freeway volumes is paramount to ensure that freeway ITS solutions, such as ramp meters, operate smoothly. Furthermore, freeway performance metrics need quality volume data to provide an accurate portrayal of real-world conditions. This dissertation focuses on improving the quality of… Read More

Rural Gentrification and the Spillover Effect: Integrated Transportation, Housing, and Land Use Challenges and Strategies in Gateway Communities

Danya Rumore Philip Stoker
Small towns and cities near national parks, public lands, and other natural amenities throughout the west are experiencing rapid growth and increased visitation. These “gateway communities” comprise a significant portion of the rural west, constituting about 31% of all communities in the U.S. Mountain West and more than 60% of those under 25,000 people. Our prior NITC-funded research shows that growth and increased tourism create a range of “big city challenges” for gateway communities,… Read More
