In this study, both stationary and comprehensive mobile monitoring platforms were developed to measure PM concentration and traffic conditions on some major highways in Southern California. The main objective is to develop a set of alternative metrics that measure particle concentrations as well as particle size.

The research objectives of this dissertation are to develop a modeling framework within an advanced activity-based travel demand model that can be used to assess the distribution of transportation cost and benefits across communities of interest and implement a data structure and variable tracking system that can be implemented within and across various modeling tools to ensure that data needed for equity assessment transfer between models, and that outputs from combined models can be used to assess equity impacts.

Long-distance travel research is limited due to the lack of robust data and the complexity of defining a long-distance trip. This study contributes to filling that gap by investigating the factors that affect the frequency of long-distance trips of Californian millennials and members of the preceding Generation X.

This dissertation aims to study effective and efficient ways for both travelers and transportation authorities to consider the actions of the other side when they make their corresponding travel or management decisions, such that certain common goals, such as mitigating congestion, reducing cost in travel expenses and improving the overall reliability of the transportation system can be achieved.

This research combines three separate dimensions of modeling the world oil market, dynamic optimization, game theory, and econometrics, to analyze the world petroleum industry, energy subsidies, and air pollution.

The objective of this dissertation is to develop and refine methods of assessing the life cycle environmental impacts and economic costs of electric vehicle technologies and policies.

The focus of this research is the design and implementation of a carbon calculator that estimates the CO2 emissions of both passenger vehicles and aviation options for surveyed real-world trips.

This dissertation estimates effects on travel behavior of two specific technological innovations – emerging shared mobility services and telecommuting – using publicly available travel surveys.

This Masters thesis describes current methods of transportation data collection and proposes new methods, as well as attempts to quantify the impact on Vermont’s roadways of the transportation-based tourism sector.
