Mineta Transportation Institute Publications

While designers produce pavement rehabilitation recommendations every day, for projects of all sizes, most designers have little information on the environmental impact of their recommendations. This research developed a new decision tool, called the “Green Up Pavement Rehabilitation Design Tool,” to allow the comparison of different rehabilitation solutions in terms of greenhouse gas emissions and to encourage sustainable practices such as materials recycling and the use of permeable, cool, and quiet pavement surfaces. The project aligns with the major goal of California Senate Bill 1, which is “to address deferred maintenance on the state highway system and the local street …

Mineta Transportation Institute Publications

The complexity of a globalized world, accelerating technological advances, and rapid change challenge educational systems. Around the world the call is to develop 21st century skills with a focus on career readiness, ability for lifelong learning, and collaboration skills. The development of the foundational elements of civic engagement (civic knowledge, skills, and dispositions) of children and youth is also a dominant concern for educators and policymakers. Unfortunately, not all youth have the same opportunities to develop civic self-efficacy. However, the civic empowerment engagement gap can be closed by providing underserved students with interactive and authentic civic experiences.

How Effective Are Toll Roads In Improving Operational Performance?, Sonu Mathew, Srinivas S. Pulugurtha

Mineta Transportation Institute Publications

The main focus of this research is to develop a systematic analytical framework and evaluate the effect of a toll road on region’s traffic using travel time and travel time reliability measures. The travel time data for the Triangle Expressway in Raleigh, North Carolina, United States was employed for the assessment process. The spatial and temporal variations in the travel time distributions on the toll road, parallel alternate route, and near-vicinity cross-streets were analyzed using various travel time reliability measures. The results indicate that the Triangle Expressway showed a positive trend in reliability over the years of its operation. The …
