Traffic participants

Vehicle-based road traffic as well as road safety affect people in every country. Analysis of this issue requires an understanding of the fundamental relationships and effects of road traffic. To this end, this thesis starts with a short summary on basics regarding traffic participants, their interaction, and the relation to safety, concentrating on the driver and pedestrian. As this work focuses on vehicle-based approaches, additional safety measures such as education or changes to infrastructure are not explicitly considered here. 

Due to the importance of hardware testing on test tracks during development, a common practice for the evaluation in safety-critical situations is introduced here. In order to achieve a subjectively realistic but objectively uncritical situation for active safety functions, so-called targets are used on test tracks instead of real traffic participants. Whereas most targets are designed for sensor or system testing, some are also suitable for behavioral studies. Many targets represent vehicles, or what a sensor or driver can perceive of a vehicle. For radar this means that a triple reflector made of... 

In this case it doesn t matter whether those injuries occur to the driver, any of the passengers or other traffic participants such as bicyclists, pedestrians or passengers of other vehicles. 

Both measures have been carried out many times and are sometimes still in practice, today, in occupational safety. However, objective tests into the effects of such measures have so far not yielded the expected results. Especially, the replacement of those individuals with the highest accident rates did not, as a rule, reduce both remarkably and at some length the accident rate of a working group (Adelstein 1952). Even extensive studies on accident repeaters in the traffic sector brought out disappointing results. For example, even if all the drivers in a study by Peck Coppin (1967) with one or more accidents had been theoretically removed from traffic participation (all...

In 1961, the United Nations finally adopted the Single Convention, the terms of which stated that each participating country could "adopt such measures as may be necessary to prevent misuse of, and illicit traffic in, the leaves of the cannabis plant."... 

This method of teaching is sometimes also referred to as Lecture-cum Demonstration Method. This is considered to be a superior method of teaching in comparison to lecture method. In lecture method the teacher speaks and students listen so it is a one way traffic of flow of ideas and students are only passive listeners. This one sidedness is the major drawback of lecture method. A teaching method is considered better if both teacher and taught are active participants in the process of teaching. This particular aspect is taken care of in demonstration method.
