The ATM IDEAS Project: Second Generation TMC Development
The acronym for MTA Bridges & Tunnels’ Advanced Traffic Management Incident Detect/Evaluate/Act System, ATM IDEAS, is true for the deployment project as well. Awarded as a design-furnish-install-test-maintain contract to Transdyn Controls, Inc., with Dunn Engineering Associates, PC, providing administrative and quality assurance services, the $12M project is using Internet-enhanced weekly teleconferences, status reporting and project management tools, and file sharing. In emulation of open-source code development, modular software development is contractually viewable by the sponsoring agency from the beginning, and paired with written documentation standards, continuous configuration management and complete off-site modular testing prior to deployment. Other project innovations include statistical task analyses based on two 24-hour observations of real TMC operations, a rapid-prototyping mock-up for user feedback and human factors analysis, the use of GIS field device configuration data, effective integration of varying audio and video sources, and the use of electronic white boarding techniques. Planned for simultaneous deployment in 2004 in the Authority’s eleven existing TMCs and a new centralized coordinating virtual TMC, the ATM IDEAS project is an early example of second-generation TMC systems engineering and software development techniques.

Field Test Results of Various Unlicensed Wireless Technologies For Transmission of Live Video
The Texas Department of Transportation is interested in determining what the best and most cost effective technology to use that provides last mile connectivity to their TranStar Transportation Management System and can provide an easy way to bridge breaks in their fiber network that occur through accident or new construction. This TxDOT sponsored evaluation identified the most cost effective technology to use by using a proof of concept demonstration in a real world environment.This paper reports the results of the test and evaluation of the data and video wireless communications using the unlicensed 2.4GHz and 5.8 GHz frequency bands over a distance of 17.4 miles. Wireless telecommunication products that were tested ranged in price from $3,700 to $12,600. Two technologies were evaluated using live video transmitted at 30 frames per second and encoded to the MPEG2 standard. They were: • 2.4 GHz ISM Band using the IEEE 802.11b standard (2 Million bits per second (Mbps) to 11 Mbps data rates) • 5.8 GHz U-NII Band compatible with the IEEE 802.3 standard (10 Mbps to 430 Mbps data rates)

A Ubiquitous Structure Health Monitoring System of Seohae Bridge
Seohae Bridge became the one of the busiest gateway of West sea and the connecting way of national industry complex for effective transportation. These systems are deteriorated and the functions of user program are too simple to expand the usage with limited measurement result. So systems were reconstructed focusing on cable stayed bridge’s intensive management. GPS systems and integrated system were built for effective management of traffic, bridge, and information communication facility management. Published in 2010 by Team of Korea Expressway Corporation.
