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.

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)

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.

Driver-Information-Systems (DIS), telematics hardware, telecommunication and IT devices become more and more part of modern vehicles. Both, technology and users, press new devices into the cockpits. Driving still remains the main task, so the design of the human machine interface (HMI) has to be done carefully to avoid loss in safety due to driver distraction.

A cross cultural usability study with existing automotive DIS supported any hypothesis on differences between users. A software tool used to produce application ready software for DIS directly out of the simulation was developed. The HMI components can easily be adapted to local market needs, without changing the major (functional) part of the program.

The City of Austin Traffic Control System is one of the newest and most advanced traffic management systems in the country. The design of the system is highly scaleable and uses commercial off-the-shelf (COTS) hardware. The system was designed to meet the needs of the users, which was to provide real-time video and data information for the timely response to the traffic management requirements of the urban surface roadway network in the City of Austin.

This paper presents a discussion of the design criteria and system architecture of the project followed by a description of some of the equipment that makes up the system and concludes with a discussion of the benefits seen as a result of the implementation of the system. As a result of the implementation of this system, the City of Austin has seen a noticeable reduction in the time it takes to respond to traffic signal trouble calls. In addition, the system has provided a means to implement or improve traffic signal synchronization on the City’s arterial corridors.
