The aim is an additional sensor system that is able to detect left behind occupants in parked cars. This should avoid the decrease of fatalities found in unattended or oversight individuals in vehicles. Based on acceleration measurements directly at the car chassis information about the occupancy is extracted. At the beginning of this paper the theory of the signal source, the used car model and the...
The European IP APROSYS (Advanced PROtection SYStems) is currently being finished. The overall project goal was to decrease the number of fatalities on European roads. Within Sub-Project 6 a novel pre-crash side impact protection system was developed which improves structural behaviour in side crash. The main focus is to reduce intrusions. The given paper presents research activities which were carried...
In this paper a study on the feasibility of a bi static radar system for bad road conditions, including water, snow and ice, is presented. First of all, the most suitable frequency is chosen among all the frequencies available for such a system from a regulatory point of view. Then, the best mathematical model for predicting the electromagnetic behaviour of different layers of water, snow or ice over...
Today most so called ‘black spots’ have been eliminated from the road networks. However, intersections can still be regarded as black spots. Depending on the region and country, from 30% to 60% of all injury accidents and up to one third of the fatalities occur at intersections. This is due mainly to the fact that accident scenarios at intersections are among the most complex ones, since different...
Traffic of heavy goods vehicles is an important component of transport in today’s cities. Much progress has been made to make it as safe and efficient as possible. In this paper, safety of heavy goods traffic at intersections is investigated. Special regard is given to the safety of vulnerable road users (VRUs), such as pedestrians and cyclist. In the project INTERSAFE-2, solutions are being developed...
Vehicle-to-vehicle and vehicle-to-infrastructure communication (V2X communication) has great potential to increase road and passenger safety, and has been considered an important part of future Intelligent Transportation Systems (ITS). Several R&D projects around the world have been investigating various aspects of V2X communication. Some of these projects focus on specific issues of V2X communication...
This paper presents experimental results regarding road condition monitoring by machine vision techniques. The system will be further developed by VTT in the European INTERSAFE-2 project, focused on applications at road intersections. Knowing the presence of adverse conditions such as icy or wet roads, important effects can be obtained for intersection safety by means of more effective driver assistance...
The intersection scenario imposes radical changes in the physical setup and in the processing algorithms of a stereo sensor. Due to the need for a wider field of view, which comes with distortions and reduced depth accuracy, increased accuracy in calibration and dense stereo reconstruction is required. The stereo matching process has to be performed on rectified images, by a dedicated stereo board,...
In the integrated research project SAFESPOT the concept of a Cooperative Pre-Data-Fusion has been implemented as a novel approach for an environmental perception system. This paper describes the approach of eliminating measurements of a Laserscanner which are not part of the environment of interest. It is being developed in the subproject INFRASENS which specifies and develops an infrastructure-based...
Nowadays, most so called ‘accident black spots’ have been eliminated from the road networks. However, intersections can still be regarded as accident black spots. Depending on the region and country, from 30% to 60% of all injury accidents and up to one third of the fatalities occur at intersections. Thus, the European R&D project INTERSAFE-2 aims to develop and demonstrate a co-operative intersection...
