Quantifying the impact of adverse weather conditions on road network performance

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...

Influence of weather on traffic flow: An extensive stochastic multi-effect capacity and demand analysis

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...

Raamwerk voor realtime reistijdvoorspellingen

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...

Bounded Acceleration Capacity Drop in a Lagrangian Formulation of the Kinematic Wave Model with Vehicle Characteristics and Unconstrained Overtaking

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...

Real-time travel time prediction framework for departure time and route advice

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...

The influence of adverse weather conditions on probability of congestion on dutch motorways

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...

Schade door files groeit weer: nieuwe economische wegwijzer TLN en EVO

In de Economische Wegwijzer van TLN en EVO staan de duurste files voor het vrachtverkeer. Na een daling van schade door weguitbreidingen is er nu sprake van een toename. Minister Schultz bracht diverse wensen van TLN en EVO dichter bij realisatie.
