Most economic models assume that individuals act out their preferences based on their own self interest. However there have also been other paradigms in the economics literature that have tried to capture alternative manifestations of human behavior that include fairness. This study examines...

On August 1st, 2007, the I-35W bridge crossing the Mississippi river fell into the Mississippi river. In addition to the human tragedy that it caused, the bridge failure also impacted how people moved in the area. The bridge carried 140,000 cars daily. As such it required a significant amount of...

In this paper we introduce an activity-based modeling approach for evaluating the traveler costs of transport network disruptions. The model handles several important aspects of such events: increases in travel time may be very long in relation to the normal day-to-day fluctuations; the impact...

This paper describes the modeling of recurring congestion in a network. It is shown that the standard economic models of marginal cost cannot describe precisely traffic congestion in networks during time-dependent conditions. Following a macroscopic traffic approach, we describe the equilibrium...

Clusters of business locations, which considerably impact daily activities, have been prominent phenomena. Yet the question of how and why Þrms cluster in certain areas has not been sufficiently studied. This paper investigates the emergence of clusters of business locations on a supply chain...

Daylight saving time (DST), implemented as an energy saving policy, impacts many other aspects of life; one is road safety. Based on vehicle crash data in Minnesota from 2001 to 2007, this paper evaluates long- and short-term effects of DST on daily vehicle crashes. To provide evidence to explain...

A 2004-2006 longitudinal panel survey of I-394 residents found support levels at over 60 percent for the congestion priced High Occupancy Toll (HOT) lane, known to the Twin Cities of Minneapolis and St. Paul as MnPASS. This number varies only slightly when sorted by income levels, gender, and...

Transportation analysts and the public decision-makers they support are confronted with a broad range of analytical tools for estimating the economic impacts of improvements to trans- portation networks. Many of the available models operate at different scales and have distinctly different...

The collapse, on August 1, 2007, of the I-35W bridge over the Mississippi River in Minneapolis, abruptly interrupted the usual route of about 140,000 daily vehicle trips and substantially disturbed the ßow pattern on the network. It took several weeks for the network to re-equilibrate, during...

Travel decisions may be very stable in a familiar environment. Major network disruptions such as the I-35W bridge collapse disrupt habitual behavior. Such ``natural'' experiments provide unique opportunities for behavioral studies, but the time window for such studies is limited. A...
