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.

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.

JustNu (translated “Right Now”) is SL’s (SL common short form for AB Storstockholms
Lokaltrafik, translated Greater Stockholm Public Transportation Authority) main focus
project to provide the Public Transportation operations four transport types (buses, local trains,
metro and commuter trains) in the Greater Stockholm area with real time traffic information
and data. The main purpose is to provide traffic information on SL transport services to be
available to all customers. This means to provide real-time reliable and easily accessible
traffic information and data, before and during the journey to the traveler, so the traveler can
plan and travel the entire journey with SL.

Effective travel time prediction is very important to many advanced traveler information and
transportation management systems. In many travel time prediction approaches, the link
travel time accumulated database (DB) and real-time link travel time information are used to
predict the link travel time. Especially, the link travel time accumulated DB, which extracts
the periodic (i.e., daily, weekly, etc.) patterns of link travel time, is believed having direct
influence on the accuracy of travel time prediction in normal traffic status. In this paper, an
automatic updating approach of link travel time accumulated DB is proposed to enclose the
long- and mid-term changes in the road traffic status caused by variations in the road
conditions (changes in road networks, etc.) and socio-economic development (changes in
vehicle ownership rate, etc.), and then improve the accuracy of the DB constantly. By
applying the approach to a probe information system in Nagoya city, it is confirmed that the
advancement of DB is useful to improve the road network coverage of travel time
information, and the accuracy of travel time prediction.
