An evaluation of speed management measures in Bangladesh based upon alternative accident recording, speed measurements, and DOCTOR traffic conflict observations

With 21,000 people annually killed in road traffic (estimated figure by World Health Organization), Bangladesh has one of the highest fatality rates in the world. Vulnerable road users (VRUs) account for over 50% of road traffic casualties, and 70% of casualties occur in rural areas. As in many Low and Middle Income Countries (LMICs), the...

The Grand Cooperative Driving Challenge 2016: Boosting the introduction of cooperative automated vehicles

The Grand Cooperative Driving Challenge (GCDC), with the aim to boost the introduction of cooperative automated vehicles by means of wireless communication, is presented. Experiences from the previous edition of GCDC, which was held in Helmond in the Netherlands in 2011, are summarized, and an overview and expectations of the challenges in the...

Tire use and road safety: Background to policy recommendations for new EU measures

TNO and TML performed a study commissioned by the European Commission regarding what measures on a European level can be taken in relation to the use of tyres to improve road safety. The study considers the use of Winter tyres, tread depth requirements, tyre inflation pressure maintenance and tyre ageing effects and damages. An assessment has...

Study on some safety-related aspects of tyre use

The tyre is a key component that affects road safety. The European commission has posted a tender aimed to study what measures on a European level can be taken in relation to the use of tyres to improve road safety. The results of this study, supported by a cost benefit analyses and carried out by TNO and TML, are described in this report. The...

IRVIN - Intelligent Road and Vehicle test INfrastructure

Simulation, or rather virtual testing, is a good instrument for study and design of traffic management concepts, traffic safety, vehicle safety and ergonomics. Simulation facilitates the evaluation of the design at an early stage and reduces the costs of making prototypes. The Dutch research organization TNO, recently started a new initiative...

Europia: Zicht op een veilige verkeerswereld

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...

Intelligent speed adaptation: Acceptance and driver behaviour on rural roads

The PROSPER (Project for Research On Speed adaptation Policies on European Roads) project, funded by the European Commission within the 5th framework program, was initiated to find answers concerning efficiency, public support, and implementation of road speed management methods, particularly Intelligent Speed Adaptation (ISA) in Europe. A part...

ITS for sustainable mobility: Tools for designing and evaluating co-operative road-vehicle systems

Intelligent co-operative road-vehicle systems, in which intelligent road-side equipment co-operates with intelligent vehicles, have great potential to improve traffic flow safety, efficiency, reliability and quality of the environment. But what concepts for these systems are both realistic and beneficial? This paper presents the objectives,...

Verslag van de werkgroep nav de lezing van Wiel Janssen, "Gedrag en veiligheid in geautomatiseerde voertuigen" [Report of the working group on the presentation by Wiel Janssen "Behaviour and Safety in Automated Vehicles"]

Apart from technical issues that have to be solved for a successful introduction of Automated Vehicle Guidance (AVG), several uncertainties about the behaviour of road users that will be exposed to telematics applications in traffic have to be tackled. The working group agreed with the first statement of Wiel Janssen, viz. that with the current...

Fundamenteel onderzoek als basis voor een duurzaam-veilige verkeersomgeving: nu of nooit [Fundamental research as a basis for a sustainably safe traffic environment: now or never]

While the introduction of a program to achieve a sustainably safe traffic environment is actively promoted by Government many elements are still missing that would permit us to say how that environment would have to look. There are known principles of how to build a system of road categorization so that road users easily understand on what road...

Speed-reducing measures for 80 km/h roads

Control of driving speeds offers an important possibility to improve traffic safety on rural 80 km/h roads. An experimental project in Drenthe was aimed at the development and testing of measures that effectively reduce speed without significantly reducing driving comfort up to speeds of 80 km/h. First, some variants of proposed infrastructural...

An empirical study of subjective road categorization

Driver behaviour will partially be a function of the cognitive schemata by which drivers represent features, functions and operations of traffic system components. This paper uses the Repertory Grid Technique to address the questions: (1) How do drivers internally represent different categories of road? (2) How are those representations mapped...

The limits of path error-neglecting in straight lane driving

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...
