Research and societal questions in the area of mobility are becoming more and more complex, covering many different aspects of the traffic system. Simulation tools are an important aid in the study of such questions. Their complexity requires an integrated mixed reality environment, in which the tools are connected to each other and to external...

EUROPIA (EUropean Road Operation Preventing Involvement in Accidents) richt zich op een doorbraak in de verkeersveiligheid door te kiezen voor een integrale boven een componentgerichte aanpak. In de simulatiewereld EUROPIA opereren verkeersdeelnemers volgens gedragsmodellen die naast reguliere regels ook gedragsfouten en vergissingen kennen. De...

In this paper subjective and objective assessments of vehicle control are illustrated by means of ex-periments concerning manipulation of vehicle dynamics, driver support, and automated driving. Subjective ratings are discussed in relation to objective performance measures.

The relation between speed choice and steering performance during curve negotiation was studied in a driving simulator. The hypothesis was that curve radius and steering competence both affect steering error during curve driving, resulting in compensatory speed choice. In this, the control of safety margins was assumed to operate as a regulatory...

This paper discusses the concept of a structurally safe traffic system. The crucial question is how potential errors occurring in traffic can be reduced by revising the layout of the road environment. Two considerations play an important role: inherent safety and self-explaining properties. Inherent safety refers to the reduction of potentially...

The design of many roads and their typical appearance reflects the way these roads developed through history. Because the road design is not considered as a system property optimally adapted to the human capabilities, there is by no means a structurally safe traffic system. The crucial question is how potential errors occurring in traffic can be...

This chapter provides a descriptive background of the driving task. Specifically it deals with those aspects of the driving context that are of special relevance to the human driver. This context is structurally determined by the triad driver-vehicle-road and functionally by situation-action elements that are revealed by driving task analyses....

In order to make road traffic safe, efficient and clean, more and more use is made of modern information and communication systems. With respect to this tendency the question rises whether automated vehicle guidance (AVG) should form an element of a future traffic system. The present paper discusses this issue. Firstly an overview is given of...

Wegomgevingen met "Self-Explaining eigenschappen" zijn omgevingen die louter door ontwerp bepaald verkeersveilig gedrag ontlokken. In deze publikatie wordt dit concept nader uitgewerkt.

Literatuurstudie naar de terminologie en criteria, welke worden gehanteerd bij het beoordelen van zichtafstanden op wegen. Geconcludeerd wordt dat de bestaande terminologie verwarrend is. Daarom wordt aanbevolen voor het aanwezige, meetbare zicht steeds de term "zichtafstand" te gebruiken. Voor de aan de zichtafstand te stellen eis wordt de term...

Elektronische oplossingen voor de heersende verkeersproblemen komen in hoog tempo op ons af. Maar die elektronische oplossingen brengen weer nieuwe vragen met zich mee. Hoeveel informatie kan een bestuurder bijvoorbeeld verwerken en hoe moet die Informatie gedoseerd worden?

The limitations of human information processing capabilities are apparent in modern road traffic. Research methods for studying road user behavior range from unobtrusive observations of actual traffic to highly controlled laboratory experiments. Often the incompatibility between controllability and validity makes the choice of a suitable method...

Open and closed-loop test procedures and subjective rating procedures on vehicle handling properties were developed and used in two experiments with an instrumented car. In the first experiment, the influences of tyre pressure variations on vehicle handling were determined in open-loop tests, i.e. steady-state curve driving, step steering inputs...

The time-to-line-crossing (TLC) concept has been used as a time-related measure to describe driving strategy. The purpose of this research is to analyze whether TLC might enlarge our understanding of the relationship between vehicle handling characteristics and a driver's looking and lateral control strategy in a straight-lane-keeping task....

It is argued that driving cannot simply be considered as a permanent, closed-loop task. Time-to-line-crossing (TLC) is used as a measure to quantify the potential role of visual open-loop and path-error-neglecting strategies. Basically, TLC represents the time available for a driver to neglect path errors until the moment at which any part of...

Based on a preview-predictor model, the time-to-line crossing (TLC) description was developed to quantify the potential role of error-neglecting strategies in driving. In a previous study the usefulness of the TLC concept was illustrated for straight lane keeping. In the present analysis TLC was applied to describe steering through a curve. When...
