Adaptive Diagnostic System Demonstration Project
Report Number: IDEA-02
The project developed a programmable PC-based tester with artificial intelligence capabilities for maintenance troubleshooting of electronic systems in transit equipment. The general system-level software and the neural network diagnostic subsystem originally proposed and designed had to be reassessed in view of the new advances in hardware and software and the results of system development and testing tasks. This led to several changes in the original work plan, which included using the preamp circuit rather than the XA-3 board as the focus of additional neural network testing and evaluation, changing the software to incorporate the Windows 95 operating system, and using and incorporating an improved test executive subsystem.

Aids for Rail Car Side-Door Observation
Aids for Rail Car Side-Door Observation
Report Number: R-004
Ensuring that rail car doors are clear before closing and train station departure has always been a significant safety issue in daily mass transit operations. Various approaches exist for performing side-door observation. These approaches range from the use of strictly manual procedures implemented by one or more persons to the use of automated observation aid devices specifically designed for the purpose. This report presents the findings of a research program designed to: a) evaluate current door observation practices and procedures and assess how they relate to transit property characteristics, such as facilities, vehicle configurations, and operating procedures; b) identify the range and scope of existing observation aids and assess their merits relative to their specific applications; c) identify promising observation technologies and define conceptual observation aids based on them; and d) develop guidelines for transit system use in the selection and implementation of observation aids for their specific application
Automatic Data Collection on Transit Users Via Radio Frequency Identification
Automatic Data Collection on Transit Users Via Radio Frequency Identification
Report Number: IDEA-10
A prototype radio frequency identification (RF/ID) tag system was designed and tested. Hardware and software were designed for an RF/ID tag system for automatic data collection on transit user movements. Work on Stage 1 involved assessing the RF/ID design for applicability to transit systems. Transit operator configuration requirements were evaluated, software and database requirements were reviewed, a preliminary system design configuration was established, and a representative bus route was selected. In Stage 2, system hardware and software specifications were developed, and a prototype RF/ID system for collecting, storing, and translating transit data was designed and built. The University of Virginia Transportation Services (UTS), which serves the student and staff population at UVA, participated in the project. In Stage 3, trial testing of RF/ID system using the Hereford College Dormitory-Hospital Complex route in the UTS system was performed and system performance and operational viability were ascertained. Potential coupling of RF/ID data collection with AVL systems was examined.

Automatic Wheel Inspection Station
Report Number: IDEA-03
An automated railroad wheel profile inspection system designed to measure wheel profiles at operating speeds using a laser scanning technology was developed and trial tested in a bench-scale demonstration. A Transit IDEA product report was published in October 1995. In Stage 1, preliminary specifications and hardware design for the system, including layout and component specifications, were completed. Several laser sensors have been tested on actual railroad wheel segments to determine the overall feasibility of the proposed approach. A bench-scale inspection station system was designed, fabricated, and tested in the laboratory. In Stage 2, in-house trial tests of the system in simulated railroad conditions were performed and operational durability and reliability of the system examined. The cost-effectiveness was assessed and an operating design of the system for routine application by transit operators was developed.

Chemical and Biological Decontamination System for Rail Transit Facilities
Chemical and Biological Decontamination System for Rail Transit Facilities
Report Number: IDEA-45
This report is an investigation into the potential use and effectiveness of a remotely operated Electrostatically Charged Aerosol Decontamination (ECAD) process for decontaminating a rail transit station after a chemical or biological release.

Cleaning and Recoating Electrified Third Rail Cover Boards
Cleaning and Recoating Electrified Third Rail Cover Boards
Report Number: IDEA-44
The purpose of this project was to develop a system to clean and recoat in place the fiberglass reinforced plastic cover boards on electrified third rails for rail rapid transit systems.  Several surface coating materials were considered and applied to deteriorated cover board segments to evaluate and to select the appropriate coating material.  This project included development, proof of concept, and prototype testing.

Cleaning Device for Electrified Third Rail Insulators -- Phase 2
Cleaning Device for Electrified Third Rail Insulators -- Phase 2
Report Number: IDEA-47
The purpose of this project was to test and demonstrate an operational higher speed device for cleaning third rail insulators for rail rapid transit systems.  Dirt and grime can short circuit an insulator and cause arcing, burning, and smoke, which can cause the rail system to be shut down.  This is the second phase of the successfully completed IDEA Project 36.

Communication of Threats: A Guide
Communication of Threats: A Guide
Report Number: R-086 Volume 01
This is the first volume of TCRP Report 86: Public Transportation Security, a series in which relevant information is assembled into single, concise volumes, each pertaining to a specific security problem and closely related issues.  This volume offers information on a variety of approaches to improving the sharing of the threat information.  Current practices, operational needs, technologies for threat information dissemination, and system functional requirements are discussed.  Effective strategies for sharing analyzed and unanalyzed reports of suspicious activities and a path to an interoperable set of national, regional, and local threat-information forums are proposed.

Community Visualization of a Light Rail Transit Oriented Development
Community Visualization of a Light Rail Transit Oriented Development
Report Number: IDEA-33
This report sets forth the principles of a novel visual assessment methodology termed Casewise Visual Evaluation (CAVE), describes its application to this problem and  summarizes the results obtained during the IDEA funded research program. In brief, CAVE is a visual assessment methodology designed to allow rapid and accurate gauging of preferences for design elements in composite scenarios.
