Many claim that, with regard to transportation infrastructure, only partnerships between public and private entities, which draw on the strengths of both, can achieve the goals of enhancing operational efficiency, increasing service delivery, improving asset maintenance, and stretching scarce...

This paper introduces a new on-demand air service (ODAS) for intercity transportation and develops traveler behavior models to predict the probability of individuals switching from the usual preferred mode of intercity transportation to the new ODAS under a rage of plausible scenarios in terms...

The transportation sector is a significant contributor to current global climatic problems, one of the most prominent problems that today's society faces. In this dissertation, three complementary problems are addressed to support emissions reduction efforts by providing tools to help reduce...

The US government annually spends billions of dollars on transit projects. State transit agencies as the owners of these projects hire designers, construction contractors, vendors, and consultants to execute the project. An appropriate project delivery method can assist them in achieving the...

The purpose of the present study was to investigate the cost and production structure of mass transit systems using both panel and time series data. Accepting cost minimization (subject to a set of constraints that reflect demand, regulatory, and urban setting conditions) as the economic...

Balancing the needs of all surface transportation modes safely and efficiently is an important objective, and especially critical at signalized intersections where turning vehicles and pedestrians share the crosswalk. This thesis identifies a significant gap in the literature for evaluating the...

A shortfall in highway funding in the U.S. is forcing highway agencies to search for viable financing options. This will likely lead to reforming fiscal policy for highway systems. A sound highway fiscal policy comprises two components: generation of adequate revenues through efficient pricing...

The purpose of this research was to address the shortcomings of the daily activity schedule model and introduce changes in the model system in order to more fully utilize the potential benefits of such a system. The major problem with the previously developed model was its full reliance on the...

A key aspect of asset management is the determination of the performance level at which a standard intervention is to be applied. A profligate policy, where an intervention is applied when the asset is in a state of higher performance, would mean frequent and premature spending of agency funds...
