Introduction and Motivation
Whereas the power of human beings
lies in logical reasoning and in the ability to adapt to unforeseen situations,
technical systems are much more powerful than human beings if reliable
and quick execution of algorithms is concerned. By built-in redundancy
and by application of self-tests and self-calibration, their reliability
can be made very high. In contrast to human beings, technical systems cannot
become tired and are not influenced by emotions. It is therefore obvious
to investigate the implementation of technical systems for automatic road
transportation in order to gain a tremendous increase in safety, reliability,
and efficiency.
The present standard of technology
makes the design of a fully automatic road transportation system possible,
which can be afforded and which can be implemented successively in combination
with the present driver controlled traffic. The following provides a detailed
description of such a system.
Abstract and Site Outline
Starting from the postulate
of requirements for fully automatic road transportation, a system architecture
is proposed consisting of 3 basic elements:
-
A central guidance system.
-
A sensor network monitoring
all cooperative and non-cooperative road users as well as random obstacles,
whose signals are also usable for precise navigation.
-
A sensor system monitoring road
conditions and traction parameters.
Requirements for these basic
elements are presented in more detail, a possible example for a sensor
usable for traffic space monitoring is regarded.
The text concludes with considerations
on system performance and implementation in compatibility with conventional
road traffic.
