A success factor in the future implementation of new in-vehicle technologies is in understanding how users will experience and respond to these devices. Although it is recognised that acceptance and acceptability are important, consistency in the definition of acceptability, and how it can be measured, is absent. In this chapter we focus on the soc...

Het Instituut voor Duurzame Mobiliteit (IDM) van;de Universiteit Gent bestudeerde van de voertuigen die in 2011 werden ingeschreven, vermogen, topsnelheid, emissies, verbruik en gewicht. Daaruit blijkt dat chauffeurs meer dan de jaren daarvoor kozen voor kleinere voertuigen, met minder uitstoot, een lager vermogen en lager gewicht. Overheidsmaatreg...

Each day, an average of over 116 people die from traffic accidents in the European Union. One out of three fatalities is estimated to be the result of speeding. The current state of technology makes it possible to make speeding more difficult, or even impossible, by placing intelligent speed limiters (so called ISA devices) in vehicles. Although th...

In Vlaanderen en Brussel is er een enorm potentieel aan extra fietsverplaatsingen want zelfs voor korte verplaatsingen stappen veel mensen nog in de auto. Maar in steeds meer steden krijgen fietsers en het openbaar vervoer meer ruimte dan de auto. In de geleidelijke modal shift die bezig is, kunnen fietsvarianten als de bakfiets of de ligfiets een...

The MOVE application focuses on the tracking and tracing of crowd and travel behaviour data by using a combination of the available sensors (GPS, Wi-Fi, cell, Bluetooth) in Smartphones. A novelty in tracing is that the application can be used as a passive logging tool or as an interactive platform in collecting additional information by a mobile su...

In-Vehicle route planning is used to support a drivertextquoteright s route choice and to guide a driver to a destination. The suggested route takes less account of environmental aspects, which could lead to cut-through traffic. The Flanders Spatial Structure plan describes certain categories of roads for the optimization of the road network based...

Intelligent Speed Adaptation (ISA) involves an in-vehicle system, which supports the driver in not exceeding the speed limit. Inappropriate speed or speeding is a major cause of road traffic accidents and strongly relates to the outcome of an accident (research indicates that in Europe one third of all fatal accidents is caused by inappropriate spe...

Speeding is generally considered to be a major cause of road traffic accidents. In-car speed assistance systems aim at reducing speeding. Several trials with different types of in-car speed assistance systems, in particular intelligent speed assistance (ISA), have shown that ISA can be an effective way to reduce speeding. A basic condition for achi...

To have knowledge about the acceptability of Intelligent Transport systems (ITS) is most beneficial for the development of supported implementation strategies. So far, different theories and methods, also stemming from other domains, have been used to define and conceptualize the notion of acceptability. In a previous paper, we developed a theoreti...

Nowadays, new technologies, such as ITS, could create alternative solutions for a better road safety. But how sure can we be whether ITS will be accepted by the people? Measuring public support of road safety defines the degree of acceptance people have to adapt or not to adapt to the desired behaviour. The focus of this paper is defining what is m...

Increasing road safety is one of the main goals in traffic policy. Measures to increase.(sustainable) road safety can be divided into infrastructural measures, which make road infrastructure and traffic situations more understandable and transparent for road users; vehicle technologies, like intelligent transport systems that increase the safety of...

Binnen het onderzoeksveld verkeersveiligheid is er erg beperkt onderzoek naar het toenemend vermogen, topsnelheid, gewicht, hoogte en breedte van voertuigen. Nochtans hebben deze factoren een invloed op verkeersveiligheid en leefmilieu. Uit een vergelijkend onderzoek (1983, 1993, 1999, 2004) van de meest verkochte merken en modellen in België wordt...

Het Centrum voor Duurzame Ontwikkeling (CDO) analyseerde het gewicht, de CO2-uitstoot en het verbruik van de 30 meest verkochte automodellen in België in 2004, en vergeleek die cijfers met de cijfers van 1983, 1993 en 1999.
