Underreporting of road accidents has been widely accepted as a common phenomenon. In many developing countries this remains a critical problem as inappropriate information regarding road accidents does not provide a base to analyse its root causes. Therefore, effectiveness of implemented interventions are always questionable. In Pakistan, responsibility of collecting initial information regardi...

Despite many efforts to improve road safety, the road accident statistics remain a concern throughout the world. This work, after considering for France in particular the possible reasons for this, proposes to extend the issue of Road Safety to the land planning problematic which responds to the characteristics of a spatialized complex system. The methodology used in the ANR program CRITERE mix...

This paper presents a multi-resolution approach for automatic extraction of roads from digital aerial imagery. Roads are modeled as a network of intersections and links between the intersections. For different context regions, i.e., rural, forest, and urban areas, the model describes relations between background objects, e.g., buildings or trees, and road objects, e.g., road-parts, road-segment...

This paper discusses how the validity of road safety evaluation studies can be assessed by analysing causal chains. A causal chain denotes the path through which a road safety measure influences the number of accidents. Two cases are examined. One involves chemical de-icing of roads (salting). The intended causal chain of this measure is: spread of salt --> removal of snow and ice from the road...

Sharply increasing fuel prices and significantly heightened concerns about environmental impacts of vehicles have dramatically changed the profile of new vehicle sales in Australia over the past few years. Specifically, sales of light and small vehicles have grown rapidly whilst the medium and particularly the large vehicle segments have contracted sharply. In the face of this, sales of four wh...

An up-to-date review of rural road accident statistics for Iran is presented The review considers sources of accident statistics in Iran and the means by which they are collected. The statistics are considered in relation to accident causal and risk factors. A comparison is made with statistics available for other countries at a similar stage of development and countries with highly developed e...
