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...

Considering knowledge gaps for automated driving in conventional traffic

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...

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...

Amitran methodology framework for evaluating the impact of information and communication technology-based measures on CO2 emissions in the transport field

Transport is an important source of air pollution and greenhouse gas emissions. Although the applications of information and communication technologies (ICTs) for transport, also known as intelligent transport systems, are seen as having great potential to help reduce emissions from road transport, their exact impact on CO<inf>2</inf> emissions...

Impact of ITS on CO2 emissions - The contribution of a standardised assessment framework

Intelligent transport systems are accepted as an integral part of the transport system. They have high potential in reducing the carbon footprint of traffic while improving efficient and safe transport. The calculation of CO<inf>2</inf> emissions arising from the transport sector incorporating the impact of ITS is a challenging task. A...

Applying intelligent transport systems to manage noise impacts

This contribution discusses how traffic management, and many other measures that can be categorised as Intelligent Transport Systems (ITS, i.e. all traffic and transport measures that use ICT) can help reduce noise levels by influencing mobility choices and driving behaviour. Several examples of such measures and how they impact noise levels...

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...

Optimising a vehicle's approach towards an adaptively controlled intersection

Traffic emissions at controlled intersections can be reduced when the possibilities of infrastructure-to-vehicle communication are put to good use. In this study the authors present two applications: one infrastructure-based and one vehicle-based that in concert are able to significantly reduce the overall emissions at a controlled intersection....

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.

Tthe relation between data quality and traffic management investigated for a simple route choice model

Dynamic traffic management and information is used by road operators in order to improve network utilisation, safety or the environment. Examples are influencing the traffic flow by influencing speeds, lane use, route choice or merging operations by employing variable message signs (VMS), Dynamic Route Information Panels (DRIPs), ramp metering...

A longitudinal driver model for modelling cooperative road-side and in-vehicle systems with the its modeller

The need for evaluation of ITS systems requires new modelling tools that allow a detailed modelling of both the roadside and the in-vehicle systems. One of the elements needed is a reliable longitudinal driver model. In this paper we outline the requirements of such a model and review the models that are available in the literature. We select...

Development of a micro-simulation model to predict road traffic safety on intersections with surrogate safety measures

This paper describes an ongoing research project at TNO in the Netherlands for assessing the safety of road networks using micro-simulation techniques. A benefit of micro-simulation comes from the ability to evaluate the safety of new ITS systems, new infrastructure design, management strategies and different traffic compositions beforehand. The...
