Book Description
This study explores the means through which automatic vehicle location (AVL) systems can be used to provide off-line data and reports for planning and management purposes. A review of the literature and discussions with transit system representatives determined that there are three distinct types of off- line activities that can benefit from the use of AVL data: planning and scheduling; line management information; and executive information. These three activities are found to generally use the same information, but require it to be presented in different formats and levels of aggregation. The system design guidelines are presented in the form of a checklist offering recommendations and suggestions to facilitate the use of AVL for planning and management information in transit properties designing or tendering new AVL systems. The guidelines cover organisational, systems, and reporting issues. The appendices contain a large selection of examples of reports generated using AVL, organised under the three types of information.

Los Alamos National Laboratory (LANL) is a unique facility covering over 43 square miles. The Emergency Management and Response Office (EM & R) is required to respond, provide Incident Command (IC), and coordination for all Laboratory emergencies. This requires IC's and support staff to respond to the actual scene of the incident. Since the IC is under numerous constraints and stress, the office wanted the capability of locating the EM & R vehicles on an electronic map. An automated vehicle location (AVL) system was required for the additional safety of the emergency response personal. The requirements for the AVL system include total automatic tracking and low cost. After careful consideration, it was determined that the most efficient and cost effective system would be based on packet radio technology as the transmission media. The location is determined by the Department of Defense Global Positioning System (GPS). The system that was designed and constructed required four components to be interfaced and communicate with each other. The first component was a GPS receiver which actually provides the location information, equipped with a digital interface to communicate location information remotely. The second component is a modem that interfaces the GPS digital interface information to a radio. The third component is the radio itself which allows for the actual information transfer from the remote GPS receiver and modem. The fourth component is the software package that provides moving maps and displays the vehicle location on that map. The equipment was all commercial off-the-shelf that only required proper integration and packaging for the AVL application. This paper describes the steps taken in the integration of the equipment into the AVL package.

Book Description
The Database and Expert Systems Applications (DEXA) conferences bring together researchers and practitioners from all over the world to exchange ideas, experiences and opinions in a friendly and stimulating environment. The papers are at once a record of what has been achieved and the first steps towards shaping the future of information systems. DEXA covers a broad field, and all aspects of database, knowledge base and related technologies and their applications are represented. Once again there were a good number of submissions: 241 papers were submitted and of these the programme committee selected 103 to be presented. DEXA’99 took place in Florence and was the tenth conference in the series, following events in Vienna, Berlin, Valencia, Prague, Athens, London, Zurich, Toulouse and Vienna. The decade has seen many developments in the areas covered by DEXA, developments in which DEXA has played its part. I would like to express thanks to all the institutions which have actively supported and made possible this conference, namely: • University of Florence, Italy • IDG CNR, Italy • FAW – University of Linz, Austria • Austrian Computer Society • DEXA Association In addition, we must thank all the people who have contributed their time and effort to make the conference possible. Special thanks go to Maria Schweikert (Technical University of Vienna), M. Neubauer and G. Wagner (FAW, University of Linz). We must also thank all the members of the programme committee, whose careful reviews are important to the quality of the conference.

Book Description
This project developed an AVL system for INDOT that utilized the statewide wireless network, SAFE-T. This option was chosen after doing a cost analysis of commercial AVL systems that use cellular data communications. The system developed provides real time information collected during snow and ice removal. Information includes weather and road conditions, truck speed, amount of chemicals spread, time, location, plow position, and road temperature. This information is displayed on INDOT GIS maps available through a browser on the INDOT network. The data is also transferred to the MDSS that INDOT uses in winter activities. This system experienced significant data transfer problems and consequently was eliminated as a viable AVL alternative. Therefore other commercial AVL systems were evaluated in this study. Other activities included investigating other hardware options for data collection and data transfer. Also, a hotspot method for data transfer was tested to do batch data transfer. A summer AVL application for paint stripping was developed. Two other commercial systems were evaluated, IWAPI and ThomTech. The IWAPI system was evaluated over three winter seasons and ThomTech for the 08-09 season. Both systems experienced data transfer problems which seems to be the biggest issue with AVL systems. Overall most users were satisfied with how the systems operated and with the information being collected and reported. The project exposed issues that exist with all types of AVL systems. There are plusses and minuses, and costs and benefits. These are described in the report. One outcome is that AVL systems are not a panacea, they offer better information and benefits, but are they economically justifiable? An internal INDOT study was performed during the 08-09 season that shows a savings of $10,000,000 in salt costs that can be attributed to some degree the use of AVL and MDSS.

Book Description
This book explores a range of important theoretical and practical issues in the field of computational network application tools, while also presenting the latest advances and innovations using intelligent technology approaches. The main focus is on detecting and diagnosing complex application performance problems so that an optimal and expected level of system service can be attained and maintained. The book discusses challenging issues like enhancing system efficiency, performance, and assurance management, and blends the concept of system modeling and optimization techniques with soft computing, neural network, and sensor network approaches. In addition, it presents certain metrics and measurements that can be translated into business value. These metrics and measurements can also help to establish an empirical performance baseline for various applications, which can be used to identify changes in system performance. By presenting various intelligent technologies, the book provides readers with compact but insightful information on several broad and rapidly growing areas in the computation network application domain. The book’s twenty-two chapters examine and address current and future research topics in areas like neural networks, soft computing, nature-inspired computing, fuzzy logic and evolutionary computation, machine learning, smart security, and wireless networking, and cover a wide range of applications from pattern recognition and system modeling, to intelligent control problems and biomedical applications. The book was written to serve a broad readership, including engineers, computer scientists, management professionals, and mathematicians interested in studying tools and techniques for computational intelligence and applications for performance analysis. Featuring theoretical concepts and best practices in computational network applications, it will also be helpful for researchers, graduate and undergraduate students with an interest in the fields of soft computing, neural networks, machine learning, sensor networks, smart security, etc.
