High risk zones, high risk conditions

Daniel Heuchenne

As far as road safety is concerned, the Walloon Region of Belgium hasconcentrated its action on two fields: the road network and the drivers'behaviour. High-risk sites are detected by means of an automatic method forsearching accident concentrations that is an extended concept of black spots.Once located, each of these sites will be submitted to a multi-criteriaanalysis taking account of the number of victims, geometry, traffic and thefrontage residents' density. Each of these sites then receives a global markindicating the importance of an intervention. The sites concerned areclassified annually according to this mark and the selected sites areanalysed from the accidents' point of view. An efficiency comparison in thencarried on and finally a confrontation with the knowledge of the physicalfield of local authorities and local road managers. When it comes to thedriver the aim is to determine the most frequent mechanical and sociologicalcauses of injury road accidents. An accident is generally due to theconjunction of several factors. Each combination of sociological andmechanical factors defines an accident sequence. The most frequent sequencesthus must be specified in order to know: 1) the mechanical causes (slipperybend, etc); 2) the targets (for instance: young unmarried drivers). Twocomplementary databases are available: the forms filled in by the policeofficers after an accident and the national survey on household mobilitycarried out in 1999. Both of these data sources have variables in common,which allows cross-checking.



Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...
