Accessibility of urban regions on a low car diet – A research agenda for digital twins

Worldwide, cities and urbanised areas attract more people and economic activities. In addition, new ways of working, shopping and recreation, mobility and ‘ownership’ are introduced – all influenced by digitalisation. The United Nations (2018) expect the world-wide population living in urbanised regions to grow from 55% to 68% by 2050. However,...

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...

Improvement of Network Performance by In-Vehicle Routing Using Floating Car Data

This paper describes a study which gives insight into the size of improvement that is possible with individual in-car routing advice based on the actual traffic situation derived from floating car data (FCD). It also gives an idea about the required penetration rate of floating car data needed to achieve a certain degree of improvement. The...

Vehicle specific behaviour in macroscopic traffic modelling through stochastic advection invariant

In this contribution a new model to include stochastic vehicle specific behaviour and interaction in traffic flow modelling is presented. The First Order Model with Stochastic Advection (FOMSA) is presented as a first order macroscopic kinematic wave model in a platoon-based Lagrangian coordinate system. The use of Lagrangian coordinates allows...

Stedelijk verkeersmanagement. Problemen van nu en oplossingsrichtingen voor de toekomst

De stad staat weer volop in de belangstelling. In de jaren ’60, ’70 en ’80 van de vorige eeuw leek

The effect of inaccurate traffic data for ramp metering: Comparing loop detectors and cameras using information utility

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

Introducing the core probability framework and discrete-element core probability model for efficient stochastic macroscopic modelling

In this contribution the Core Probability Framework (CPF) is introduced with the application of the Discrete-Element Core Probability Model (DE-CPM) as a new DNL for dynamic macroscopic modelling of stochastic traffic flow. The model is demonstrated for validation in a test case and for computational efficiency on two simple networks. The CPF...

Scanning tour USA. Traffic management: the American blend

In The Netherlands traffic management is being considered a serious policy option to deal with traffic congestion and its negative impact on safety, economy and livability. Building new roads is often not feasible due to a lack of space, environmental and funding issues. Also, pricing is not an option for the next couple of years due to...

The future of traffic management. State of the Art, Current trends and perspectives for the future

In just a few years, traffic management has been transformed from an everyday, passive task for the highway authority to an important policy instrument. This transformation is not without reason. Traffic management has improved the safety and operations on our roadways, while it is relatively inexpensive, flexible and rapidly deployable....

Verkeersmanagement in de toekomst

TrafficQuest (het Expertisecentrum Verkeersmanagement) is een samenwerkingsverband tussen Rijkswaterstaat DVS, TNO en de TU Delft, met als doel het bundelen, ontwikkelen en ontsluiten van kennis over verkeersmanagement. De afgelopen tijd heeft TrafficQuest kritisch nagedacht over de stand van zaken met betrekking tot verkeersmanagement en de...

De toekomst van verkeersmanagement. Stand van zaken, ontwikkelingen en perspectief

In de afgelopen decennia heeft het mobiliteitsvraagstuk zich ontwikkeld tot een hardnekkig probleem. De sterke toename van de vraag naar mobiliteit (en capaciteit) van de laatste jaren komt voor een groot deel voor rekening van het personenauto- en vrachtwagenverkeer. De combinatie van autonome groei van het autogebruik en een sterke groei van...

De toekomst van verkeersmanagement. Stand van zaken, trends en perspectief

Verkeersmanagement is in enkele jaren tijd uitgegroeid van ‘een taak erbij’ voor de wegbeheerder tot een belangrijk beleidsinstrument. Dat is niet zonder reden. Verkeersmanagement heeft de doorstroming en veiligheid op de weg verbeterd, terwijl het toch relatief goedkoop, snel inzetbaar en flexibel is. Verkeerskundigen zijn er bovendien van...
