In a bid to cost-effectively tackle congestion, traffic management is often seen as a key option to utilise road capacity. Prior to the application of traffic management measures, a-priori analysis allows the effectiveness of measures to be judged and where necessary adapted. However, current approaches do this without considering the effects of...

Major and minor disturbances can have a considerable impact on the performance of road networks. In this respect, resilience is con-sidered as the ability of a road section to resist and to recover from disturbances in traffic flow. In this contribution, an indicator is pre-sented, the Link Performance Index for Resilience (LPIR), which eval...

Adverse weather conditions regularly lead to severe congestion and large travel time delays on road networks all over the world. Different climate scenarios indicate that in the future adverse weather conditions are likely to become more frequent, last longer and will be more extreme. Although climate mitigation measures are being taken, it...

Abstract—With increasing numbers of vehicles using low level automation and higher level automation expected in the future, significant effects are expected on traffic flow. Despite much simulation and driving simulator research on SAE level 1 vehicles, there remain many questions in regard to the effects of the systems on traffic flow. The...

Traffic is affected by a wide range of variables. An influential and commonly occurring variable on traffic flow is the weather. Weather conditions affect both traffic demand as well as road capacity and in doing so also affect the traffic fluency, or rather the ability of traffic to maintain a certain level-of-service. In this contribution it...

Het beste routekeuze- en vertrektijdstipadvies is gebaseerd op betrouwbare reistijd-voorspellingen. Een nieuwe ontwikkeling is een raamwerk dat plaats biedt aan verschillende voorspelmethoden waaruit de 'hypothesemanager' de juiste methoden combineert voor dát tijdstip, op die locatie onder die verwachte weersomstandighe-den. Dit raamwerk is...

In this contribution a model-based analysis of the application of bounded acceleration in traffic flow is considered as a cause for the capacity drop. This is performed in a Lagrangian formulation of the kinematic wave model with general vehicle specific characteristics. Unconstrained overtaking is presumed, which allows a demonstration to be...

Heavily used urban networks remain a challenge for travel time prediction because traffic flow is rarely homogeneous and is also subject to a wide variety of disturbances. Various models, some of which use traffic flow theory and some of which are data driven, have been developed to predict traffic flow and travel times. Many of these perform...

Weather conditions are widely acknowledged to contribute to the occurrence of congestion on motorway traffic by influencing both traffic supply and traffic demand. To the best of our knowledge, this is the first paper that explicitly integrates supply and demand effects in predicting the influence of adverse weather conditions on the probability...

De Economische Wegwijzer wordt jaarlijks uitgebracht door TLN in samenwerking met EVO. In de Economische Wegwijzer staat een overzicht van de duurste files van Nederland, vanuit het oogpunt van het vrachtverkeer. Files veroorzaken niet alleen grote ergernis voor het vrachtverkeer, maar door de vertragingen zorgen ze ook voor financiële schade....

In probabilistic traffic models, consideration of stochasticity in the dynamics of traffic gives a closer representation of a traffic system in comparison to that of a deterministic approach. Monte Carlo simulation is a broadly accepted method to consider variations in traffic within modelling. In this contribution, the possibility of increasing...
