On investigation of traffic safety based on statistical data regarding vehicle type and road infrastructure

Fülep T., Nadai L., Rövid A.

Safe traffic is a key factor for both social players and the sustainable development of the economy. The various interest groups involved in traffic each have their own role in making our roads safe. The large number of traffic accidents and their grave consequences represent a real problem all over the world (see, for instance, the incredibly crowded metropolises of Southeast Asia or the megacities of Latin-American). A successful innovative activity in this field performed on a worldwide scale contributes to solving a critical social and economic issue. Due to the more easily available European statistical data, the paper is going to present the causes of accidents and examine possible solutions. A 2001 objective of the European Union requires a 50 per cent reduction in the number of fatal road accidents by 2010. Although a number of effective measures have been implemented in the field of traffic safety, the number ofroad accidents is still unacceptably high in the EU: a total of 1.3 million accidents per year result in close to 40,000 deaths and 1.7 million injuries. There is a large body of statistical data available (bothfrom Hungary andfrom Europe) and several comprehensive researches discuss the types of accidents. Available analyses are going to made on what kind of active or passive vehicle safety systems could have helped avoid the accidents. These analyses have and still define the main directions for legislation and technical developments.

Suzuki Motor Corporation (SMC) recognizes the importance of collaborative projects with Universities and how it contributes to technological development effectively. In spite of the world economical depression, several projects could get started this year leaded by SMC. As a researcher of SMC, Author takes charge of two collaborative projects and introduces these as typical examples of the most successful collaborations. The first is, "3D Measurement System for Crash Tested Car" at Shizuoka University (Japan) and Budapest Tech Polytechnical Institute (Hungary) from 2008; the second is, "High-Accuracy Stereo Vision System Based on Phase-Only Correlation (POC) and Its Application to metal Component Inspection" with Tohoku Univ. (Japan) 2003-2005. By these collaborations, the profound knowledge of universities has a lot of possibility to suits the technical needs of SMC.

We have been studying the high-precision three-dimensional measurement system using cameras. In this paper, our system is verified, and its application is reported. The principle of our measurement system is based on the stereo measurement. In our system, reducing the quantization error by numerical processing can realize the highprecision 3D measurement at the long distance. This measurement system has many applications, such as industrial use, ITS, robotics, and many others. Our system has been applied on the observation of the glacier. The Perito Moreno glacier, which is our target, moves very fast and the moving speed is reported as about 2 m/day. Then, it is thought that the important information about the global warming can be obtained by observing this glacier. But, as the width of the glacier is several km, there were no reports of continuously observing the movement of the glacier in high accuracy. As a result, the unique observation results about the daily movement of the glacier were measured. The observation of the glacier flow was carried out for the third straight year. In this paper, the valuable results of the glacier observation and experimental results to verify the precision are discussed.
