Modern Project Prioritization for Transportation Investments

Historically, transportation agencies’ main priority has been to fund, build and expand highways to safely meet the growing demand for vehicle travel. Their project prioritization processes, therefore, have focused primarily on improving capacity along the most congested major routes. Many of these agencies, however, have experienced a shift in priorities toward the maintenance of existing […]

Evaluation of Cost-Effective Alternative Designs for Rural Expressway Intersections

High-speed expressways functionally operate like freeways but have at-grade intersections that provide critical access to communities via minor roadways. These intersections provide key economic entry points to jobs and economic development and serve as lifelines for rural communities. They also provide ingress and egress for emergency vehicles and serve as evacuation routes in cases of […]

Making Tolling Transparent: Analyzing Processes Used to Allocate & Distribute Toll Highway Revenue in Multiple States

Transportation finance has become increasingly unreliable in recent years, due to the declining revenue available from the motor fuel tax, increasing auto efficiency, and political reluctance to raise taxes. In many states, this has led to deferred maintenance, poor road quality, and failure to satisfy demand for better infrastructure. Some states have relied on toll […]

Multi-Criteria Decision-making Approach for Building Resilient and Sustainable Transportation Infrastructure

This project will develop and validate a multi-criteria decision-making approach for enhancing the longevity of transportation infrastructure built on problematic test site conditions that includes poor subsoil conditions. In the United States, the annual cost of damage to constructed facilities built on problematic subsoil conditions was approximately $13 billion, and a significant portion of this […]

Overcoming Local Barriers to Regional Transportation: Understanding Transit System Fragmentation from an Institutionalist Framework

While the federal government spends billions on transit projects each year, many regions have poor coordination of services, with some regions having over 21 transit agencies failing to offer integrated schedules, fares and services, while other regions have large swaths that are completely unserved. Many of these inefficiencies are not due to a lack of […]
