This paper examined the day-to-day variability of the journey-to-work trips, including the departure time, route choice, and trip chaining behavior, using GPS-based disaggregate morning commute data of 56 drivers during a one-week period. Data were collected from the ongoing instrumented vehicle projects in Atlanta sponsored by NHTSA and FHWA. The paper examines alternate measurements of the da...

The paper is concerned with Nash equilibrium solutions for the LighthillWhitham model of traffic flow, where each driver chooses his own departure time in order to minimize the sum of a departure cost and an arrival cost. Estimates are provided on how much the Nash solution may change, depending on the cost functions and on the flux function of the conservation law. It is shown that this equili...

Influence of Conscientiousness Page numbers The Influence of Conscientiousness on the Dynamics of Institutional Departure Over the years concerns have increased about retention and attrition in higher education. In order to develop and improve retention services it is important to understand the underlying dynamics associated with institutional departure. As opposed to research on college perfo...

traveler information. The initiative focuses on real-time information to help travelers make informed decisions about their travel options. The Smart Trek project has brought about a variety of real-time transit information applications. One of these is MyBus, which makes departure predictions and delivers traveler information to Web browsers and cell phones. MyBus aims to present to riders, in...

Queueing network models have proven to be very useful in the analysis of communication systems. The departure process of a queue in a queueing network is of special interest because it is the arrival process to other queues in the network. For high speed networks, correlation and burstiness are very important factors for system performance and thus the smooth Bernoulli process is no longer a go...

Macroeconomics and econometrics are tools for recognizing patterns in data and interpreting them in ways that distinguish cause from coincidence. What attracted me to macroeconomics were its noble goals of identifying the causes of economic depressions and of understanding how government policies can promote prosperity. In graduate school, I learned that modern macroeconomics required more math...

In the integrated aircraft routing, crew scheduling and flight retiming problem, a minimum-cost set of aircraft routes and crew pairings must be constructed while choosing a departure time for each flight leg within a given time window. Linking constraints ensure that the same schedule is chosen for both the aircraft routes and the crew pairings, and impose minimum connection times for crews th...

Boiling heat transfer is a key thermal limit in nuclear systems. However, for decades, its modeling has relied on speculative hypotheses and a good dose of empiricism. As researchers now start to develop more mechanistic models, the need for high-quality high-resolution data on the bubble nucleation and growth cycle is increasing. Specifically, nucleation site density, bubble departure diameter...
