Travel demand matrix estimation for strategic road traffic assignment models with strict capacity constraints and residual queues

This paper presents an efficient solution method for the matrix estimation problem using a static capacity constrained traffic assignment (SCCTA) model with residual queues. The solution method allows for inclusion of route queuing delays and congestion patterns besides the traditional link flows and prior demand matrix whilst the...

Extension of a static into a semi-dynamic traffic assignment model with strict capacity constraints

To improve the accuracy of large-scale strategic transport models in congested conditions, this paper presents a straightforward extension of a static capacity-constrained traffic assignment model into a semi-dynamic version. The semi-dynamic model is more accurate than its static counterpart as it relaxes the empty network assumption, but,...

Static Traffic Assignment with Queuing: Model properties and applications

This paper describes the road traffic assignment model Static Traffic Assignment with Queuing (STAQ) that was developed for situations where both static (STA) and dynamic (DTA) traffic assignment models are insufficient: strategic applications on large-scale congested networks. The paper demonstrates how the model overcomes shortcomings in STA...

Onverwachte effecten van informatieverschaffing

Dat je met verkeersinformatie de routekeuze van weggebruikers kunt beïnvloeden, behoeft geen betoog. Maar kun je het effect van informatieverschaffing ook in een model vervatten? Jazeker, laten de auteurs van deze tutorial zien. Bij modeltoepassingen gericht op onder meer netwerkbetrouwbaarheid en -robuustheid is die effectbepaling zelfs...

Modelling Traveller Behaviour under Emergency Evacuation Conditions

Dynamic traffic simulation models are frequently used to support decisions when planning an evacuation. This paper focuses on limitations in the modelling of travellers’ behaviour with respect to traffic information and compliance to evacuation instructions. More specifically, we propose a model framework where the traffic simulation is executed...

A review on travel behaviour modelling in dynamic traffic simulation models for evacuations

Dynamic traffic simulation models are frequently used to support decisions when planning an evacuation. This contribution reviews the different (mathematical) model formulations underlying these traffic simulation models used in evacuation studies and the behavioural assumptions that are made. The appropriateness of these behavioural assumptions...

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...

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...
