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.

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.

Bandwidth Expansion and Real-Time Surveillance for Security on Transit Buses
Bandwidth Expansion and Real-Time Surveillance for Security on Transit Buses
Report Number: IDEA-37
The purpose of this project was to develop a real-time video surveillance technology for enhanced security on transit buses.  The system uses digital cameras on buses, and adds a broad-bandwidth wireless network modem and software to expand the bandwidth for the wireless transmission of streaming digital video.

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.

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.

Compact Disc - Interactive Violence Prevention Training Program
Compact Disc - Interactive Violence Prevention Training Program
Report Number: IDEA-11
This project developed and demonstrated an interactive compact disc multimedia training program in a video and a CD-ROM format. The goal of the project was to improve the transit employee's ability to handle incidents of violence and aggression. The project has undergone several format changes dictated by changes in technology since the project was initiated. The training program implementation strategies were under development in coordination with the National Transit Institute at Rutgers University and a number of transit agencies. San Francisco Municipal Railway (MUNI) collaborated with the National Transit Institute and six other transit properties around the country in developing and testing this training program. The production of the compact disc program, "Customers, Conflicts, and You: A Transit Operator's Guide to Problem Solving," has been completed. The visual and audio materials were reviewed and assembled, and a database of these assets--audio and visual components--was created. The final revised narration, music, and sound were recorded. The final version of the video was completed at an on-line post-production facility. In addition, the program interface design, art, learner log-in, computer mouse tutorial, and the navigational tutorial were finalized. The assets were digitized. The training package, incuding the video and CD-ROM and Instructor Guidebook has been completed. It is available from the National Transit Institute.
