Evacuation modeling including traveler information and compliance behavior

Traffic simulation models are often used to support decisions when planning an evacuation. Scenario analyses based on these models then typically focus on traffic dynamics and the effect of traffic control measures in order to locate possible bottlenecks and predict evacuation times. A clear approach to incorporate traveler information and...

Dynamic Equilibrium Assignment Convergence by En-route Flow Smoothing

An essential feature in many dynamic traffic assignment (DTA) models used for planning purposes is to compute the (dynamic) equilibrium assignment, where travellers follow user-optimal routes, leading to minimal experienced route travel times. To compute these time-varying route flows in the equilibrium assignment, an iterative procedure is...

EVAQ: An Evacuation Model for Travel Behavior and Traffic Flow

Model-based Optimal Evacuation Planning anticipating Traveler Compliance Behavior

Instructing evacuees on their departure time, destination, and route can lead to more efficient evacuation traffic operations. While current evacuation plan optimization techniques are limited to assessing mandatory evacuation where travelers strictly follow the instructions, in reality a share of travelers likely decides not to comply. Here we...

A generic method to optimize instructions for the control of evacuations

A method is described to develop a set of optimal instructions to evacuate by car the population of a region threatened by a hazard. By giving these instructions to the evacuees, traffic conditions and therefore the evacuation efficiency can be optimized. The instructions, containing a departure time, a destination, and a route, are created...

Verkeersmanagement bij exceptionele omstandigheden

Hoe kwetsbaar onze verkeersinfrastructuur is, blijkt wel bij exceptionele omstandigheden. Eén incident (calamiteit of ongeval) en er ontstaat een verkeersinfarct. Kan dit worden voorkomen? Zo ja, hoe dan? Zijn er bruikbare modellen om effecten in te schatten? En hoe staat het met de human factor, welhaast in elke keten de meest kwetsbare schakel...

Evacuation plan evaluation: Assessment of mandatory and voluntary vehicular evacuation schemes by means of an analytical dynamic travel model

In this paper an evacuation simulation model is proposed, combining a dynamic travel demand component, an adaptive travel choice behavior component, and a dynamic network loading component. The travel demand component considers the primary choice facing the endangered residents, whether to participate in the evacuation, and if so, when to depart...

Salt transport in plaster/substrate layers

Analysis of coupled mass transfer and sol-gel reaction in a two-phase system

The coupled mass transfer and chemical reactions of a gel-forming compound in a two-phase system were studied in detail. Tetra-methyl-ortho-silicate (TMOS) is often used as a precursor in sol-gel chemistry to produce silica gels in aqueous systems. TMOS can also be mixed with many hydrocarbons without chemical reaction, which allows for various...

Composition of mortar as a function of distance to the brick-mortar interface: A study on the formation of cured mortar structure in masonry using NMR, PFM and XRD

The formation of cured mortar structure in masonry was studied using multiple experimental techniques. Starting with fresh mortar, nuclear magnetic resonance (NMR) was used to measure the water extraction during brick laying. After curing, the composition of cured mortar was investigated with polarizing and fluorescent microscopy (PFM) and X-Ray...

Electrokinetic salt removal from porous building materials using ion exchange membranes

The removal of salt from porous building materials under the influence of an applied voltage gradient normally results in high pH gradients due to the formation of protons and hydroxyl ions at the electrodes. The formed acidic and alkaline regions not only lead to disintegration of the porous material, but also affect the salt transport. In this...
