Book Description
Over the past year we have worked on the development of a real-time laser-based non-intrusive field-deployable detection system for delineation of moving vehicles. The primary goal of the project is to develop a roadway detection system that can be used to gather reliable travel time data non-intrusively. Microprocessor is used to control digital-controlled potentiometer (DCP), which adjusts the gain of sensors' signals. It adjusts the system quickly on highway with only pushing a button. The adjustment, which used to take half or an hour, needs only several seconds. Meantime, the microprocessor is also able to filter noise after having finished the task of adjustment. The software of the system is rebuilt for 8 channels, which used to be for 4 channels, to be able to obtain more information of vehicles even like the outline of vehicle. In order to improve the precision of the system, we improved the mechanical design, optical design and electric circuit design. The frequency of laser pulse is 10 kHz and the sample rate of computer DIO96 board is also 10 kHz. This document describes the design and implementation of each functional component of the field-deployment system, the configuration of the field detection system, and software design and implementation. This report also discusses optical techniques that may potentially be used for the detection of trace amounts of gases such as CO, CO2, NO and NO2 through the use of an overhead detector that employs signal reflection from a roadway like the Laser-Based Detection System. These gas species are relevant to detection of highly polluting vehicles.

Book Description
What is computational intelligence (CI)? Traditionally, CI is understood as a collection of methods from the ?elds of neural networks (NN), fuzzy logic and evolutionary computation. Various de?nitions and opinions exist, but what belongs to CI is still being debated; see, e.g., [1–3]. More recently there has been a proposal to de?ne the CI not in terms of the tools but in terms of challenging problems to be solved [4]. With this edited volume I have made an attempt to give a representative sample of contemporary CI activities in automotive applications to illustrate the state of the art. While CI researchand achievements in some specialized ?elds described (see, e.g., [5, 6]), this is the ?rst volume of its kind dedicated to automotive technology. As if re?ecting the general lack of consensus on what constitutes the ?eld of CI, this volume 1 illustrates automotive applications of not only neural and fuzzy computations which are considered to be the “standard” CI topics, but also others, such as decision trees, graphicalmodels, Support Vector Machines (SVM), multi-agent systems, etc. This book is neither an introductory text, nor a comprehensive overview of all CI research in this area. Hopefully, as a broad and representative sample of CI activities in automotive applications, it will be worth reading for both professionals and students. When the details appear insu?cient, the reader is encouraged to consult other relevant sources provided by the chapter authors.
