Modeling Traffic Disruptions during Mass Evacuation

Dynamic modeling of plasma - vapor interactions during plasma disruptions *

Intense deposition of energy in short times on fusion reactor components during a plasma disruption may cause severe surface erosion due to ablation of these components. The exact amount of the eroded material is very important to the reactor design and its lifetime. During the plasma deposition, the vaporized wall material will interact with the incoming plasma particles and may shield the res...

Traffic Flow Models and the Evacuation Problem

In our paper, we consider several models for traffic flow. The first, a steady state model, employs a model for car following distance to derive the a traffic flow rate in terms of empirically estimated driving parameters. From this result, we go on to derive a formula for total evacuation time as a function of the number of cars to be evacuated. The steady state model is analytically convenien...

Optimizing Traffic Signal Control for Emergency Evacuation

Agent‐Based Modeling (ABM) is an effective strategy for simulating the emergent properties of complex systems. This form of simulation models the behaviors of individual agents interacting with each other and with their world. ABM is well suited for problems such as modeling behaviors during emergencies, or critical incidents. These situations can range from getting people out of a burning buil...

Evacuation Planning Using the Integrated System of Activity-based Modeling and Dynamic Traffic Assignment

A simulation-based optimization approach to reschedule train traffic in uncertain conditions during disruptions

Delays and disruptions reduce the reliability and stability of the rail operations. Railway traffic rescheduling includes ways to manage the operations during and after the occurrences of such disturbances. In this study, we consider the simultaneous presence of large disruptions (temporary full or partial blockage of tracks) as well as stochastic variation of operations, as a source of disturb...
