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 flow pattern on the network. It took several weeks for the network to re-equilibrate, during which period, travelers continued to learn and adjust their travel decisions. A good understanding of ...

Thanks to their ability simulate the travel behavior at individual scale, agent-based models have gained popularity over last years. These are data-intensive, with regards transport supply and demand. In particular, a detailed description of population its is required. Bayesian Networks (BNs) directed acyclic graphs representing joint probability distributions. They recently been employed for s...

The value of travel time savings (VTTS) is the monetary value attached to save a determined amount of travel time. VTTS is also the most important benefit category aimed at justifying investments in transport infrastructures by public administrations. Hence VTTS played a significant role in various economic studies, both analytical and empirical (Zamparini & Reggiani, 2007). "It is difficult to...

The general multimodal network equilibrium problem with elastic balanced demand is studied. This problem is a combination of trip distribution, modal split and trip assignment problems. The problem is approached from an asymmetric network equilibrium point of view with side constraints. The balances for travel demand are taken as side constraints. These balances do not guarantee that the proble...
