Book Description
INTELLIGENT TRANSPORT SYSTEMS TECHNOLOGIES AND APPLICATIONS This book provides a systematic overview of Intelligent Transportation Systems (ITS), offering an insight into the reference architectures developed within the main research projects. It delves into each of the layers of such architectures, from physical to application layer, describing the technological issues which are being currently faced by some of the most important ITS research groups. The book concludes with some end-user services and applications deployed by industrial partners. The book is a well-balanced combination of academic contributions and industrial applications in the field of Intelligent Transportation Systems. It includes the most representative technologies and research results achieved by some of the most relevant research groups working on ITS, collated to show the chances of generating industrial solutions to be deployed in real transportation environments.

Book Description
The detection of freeway incidents is an essential element of an area's traffic management system. Incidents need to be detected and handled as promptly as possible in order to minimize traffic delays. Various algorithms and detection technologies are examined to determine which combinations offer optimized detection performance. This study represents an effort to compile, compare, and rank available incident detection strategies.

Book Description
This report describes optimization techniques which have been developed and applied for the evaluation of design and operations of freeway incident detection-service systems. The report has four major parts: (1) analysis and design of stationary service systems; (2) analysis and design of incident detection algorithms; (3) analysis and design of incident response systems; and (4) analysis and design of freeway on-ramp traffic-responsive control methodology for normal and incident conditions.

Book Description
Project 0-4745 developed a geographic information system (GIS)-based approach for the determination of patterns in the spatial and temporal distribution of incidents along freeway corridors. The research documented incident detection and data archival at several transportation management centers (TMCs) in Texas, a process to develop a data model and geodatabase of intelligent transportation system (ITS) equipment and archived ITS data, and a process to determine patterns in the spatial and temporal distribution of freeway incidents. This report contains products 0-4745-P3 (which includes detailed incident evaluation procedures) and 0- 4745-P4 (which addresses process definitions and implementation recommendations) that were developed during the second phase of research project 0-4745.

Book Description
Critical to intelligent transportation systems (ITS) is an efficient form of surveillance on freeways to detect incidents. Traditionally, loop detectors or another form of passive detection have been used to meet this need. Due to the high cost, difficulty of timely installation, and limited funding available to deploy ITS systems, the traditional system has been slow to develop in the Dallas area. This research assesses the feasibility of substituting driver-based incident detection using cellular phones for traditional passive detection. The study is divided into five major tasks: (1) summary of current cellular incident reporting services; (2) identification of issues and potential effectiveness of cellular incident detection in Dallas; (3) development of an implementation plan for driver-based cellular detection; (4) comparison of traditional and cellular incident detection methods; and (5) identification of potential funding sources for the implementation plan. This document concentrates on reporting on the development of the implementation plan for driver-based cellular detection in Dallas. Based on evaluation of existing driver-based cellular incident detection programs and interviews with local public safety officials, researchers decided to rely on the existing 911 system for incident detection instead of having a new number, such as *999, created. Based on this decision, the implementation plan contained four major components: (1) driver education campaign, (2) deployment of reference location signs on the freeway network, (3) establishment of communication interfaces between local 911 centers and TxDOT's Dallas Traffic Management Center, and (4) expansion of CCTV camera network for incident verification. All of these components combined together will form an effective incident detection and verification system that should allow the deployment of passive detection, such as loop detectors, to be scaled back accordingly.
