Transportation agencies spend billions of dollars annually on managing a wide range of assets to meet public, legislative, and agency expectations. These assets vary from the physical transportation infrastructure, to equipment, material stocks, data and information, and human resources. The...

Time-constant assumptions in discrete-response heterogeneity models can often be violated. To address this, a time-varying heterogeneity approach to model unobserved heterogeneity in ordered response data is considered. A Markov switching random parameters structure (which accounts for...

Airport security screening, and the amount of time it costs travelers, has been a persistent concern to travelers, airport authorities, and airlines – particularly in recent years where changes in perceived threats have resulted in changes in security procedures that have caused great...

One of the key aspects of graduated driver licensing programs is the new-driver experience gained in the presence of a guardian (a person providing mandatory supervision from the passenger seat). However, the effect that this guardian-supervising practice has on adolescent drivers’...

The evaluation of transportation projects has traditionally been carried out in the context of economic efficiency in terms of savings in travel time, vehicle operating cost, and safety. The broader long-term effects on economic development (i.e., job, income and business growth) are a concern...

This paper studies public transport demand by estimating a system of equations for multimodal transit systems where different modes may act competitively or cooperatively. Using data from Athens, Greece, we explicitly correct for higher-order serial correlation in the error terms and investigate...
