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...

The EU FP7 project eCoMove created an integrated solution for more energy efficient road transport based on cooperative technology. The project's core concept assumed that there is theoretical minimum energy consumption achievable with the "perfect eco-driver" travelling through the "perfectly eco-managed" road network. Microscopic traffic flow...

Future air traffic is expected to grow increasingly, opening up a gap for task dependent automation and adaptive interfaces, helping the Air Traffic Controller to cope with fluctuating workloads. One of the challenging factors in the application of such intelligent systems concerns the question what the operator is doing in order to optimize...

Traffic noise at an intersection controlled by traffic lights shows noise level variations due to the alternating green and red lights for the different trafficstreams. Noise peaks caused by automobiles pulling up or passing by at highspeed may be quite annoying for people living near the intersection. Detailedprediction of the variations is...

The Amitran FP7 project will define a reference methodology to assess the impact of intelligent transport systems on CO2 emissions. The methodology is intended to be used as a reference by future projects and covers both passenger and freight transport. The project will lead to a validated methodology, described in a handbook and complemented by...

Cooperative Systems will play a critical role in enabling safe, smart and clean transport, as well as meeting the European Commission's 2020 policy goals. There is today a general understanding of the benefits of cooperative systems but there is still a need for further validation of the estimated benefits based on large scale trials. Progress...

Motivation/Research approach - An exploratory study was conducted to investigate whether eye movement metrics discriminate between different air traffic control tasks. Findings/Design - The results show the three tasks elicit different eye movement, as Yarbus (1967) also showed in static pictures, and that a number of eye tracking metrics...

Advanced packet scheduling schemes in 3G/3G+ mobile networks provide one or more parameters to optimise the trade-off between QoS and resource efficiency. In this paper we study the sensitivity of the optimal parameter setting for packet scheduling in LTE radio networks with respect to various traffic and environment aspects. For our...

Within the coming years, the developments of infrastructural and in-vehicle ITS systems will come together and result in the development of cooperative vehicle-infrastructure ITS systems. The development of these integrated cooperative systems will require new modelling tools that allow a detailed modelling of both the roadside and the in...

This paper investigates the effects of dynamic road marking on the Ring around Amsterdam. This Ring is congested during most of the day, but especially during the peak periods in the morning and evening rush hours. The goal is to determine what (traffic) effects, if any, can be found by applying Dynamic Road Marking during the morning rush hours...

We present an analytical study of throughput measures in processor sharing queuing systems with randomly varying service rates, modelling e.g. a communication link in an integrated services network carrying prioritised fixed rate stream traffic and rate-adaptive elastic traffic. A number of distinct throughput measures for the elastic traffic...

Knowing the position and speed of the vehicles on the road network in real-time is one of the major challenges that vehicle control and traffic management applications are facing. Wireless sensor networks received significant attention in the last decade and successful research put them in the forefront to answer this challenge. Wireless sensor...

Does consideration of average speed distributions on roads-as compared to single mean speed-lead to different results in emission modelling of large road networks? To address this question, a post-processing method is developed to predict mean speed distributions using available traffic data from a dynamic macroscopic traffic model (Indy) that...

Increased availability of sensing, communication and computing equipment in modern vehicles presents opportunities for a generational advance in driver assistance and safety functions. However, the growth in the volume and complexity of data also presents challenges for its collection, maintenance and distribution. The SAFESPOT Local Dynamic Map...

The application of Incident Management to the Dutch road network suffers from serious problems in terms of availability of accurate and up-to-date information. In this paper we present an approach aimed at diminishing the occurrence of misunderstandings. This approach is based on the concept of network enabled capabilities. This technique allows...

Local habitability is coming under increasing pressure from harmful traffic emissions. This emission is strongly correlated to the characteristics and dynamics of traffic: type of vehicle, speed, acceleration and deceleration. This paper investigates the use of integrated road-vehicle systems for environmental objectives. It defines a new...

Advances in network technologies enable distributed systems, operating in complex physical environments, to coordinate their activities over larger areas within shorter time intervals. Some envisioned application domains for such systems are defence, crisis management, traffic management and public safety. In these systems humans and machines...

Fixation times are known to decrease after multiple exposures to the same road in simulated environments. The present study investigates whether this also holds for real driving and for watching a video, which was taped during driving (while simulating steering and braking). It appeared that the fixation times for traffic signs, information...

Traffic is sensed using a signal from a wave reflection detection device to classify road users into different types. Classification is performed dependent on statistical properties of reflections. Preferably reflections are resolved into reflections for different combinations of position and speed, and road users are classified, dependent on a...
