The Future of Dynamic Traffic Assignment

November 21, 2010

Transportation planners and engineers today are faced with complex analyses of innovative applications such as system performance, reliability, managed lanes, congestion pricing, one-way two-way conversion, construction detour, and more. Traditional analysis tools, including travel-demand modeling and microsimulation, often do not meet the analyst’s needs or the available budget. As a result, simulation-based Dynamic Traffic Assignment (DTA) has been rapidly gaining popularity and becoming the tool of choice for such applications.

PowerPoint slides included.

Technology Helps Professionals Share Information and Engage Stakeholders

April 14, 2009

The reaches of technological advancements continually evolve and grow, expanding the depth of resources available to transportation professionals. Technology, as a means for clearly communicating complex ideas and solutions, is invaluable for collecting and sharing data. Researchers use technology to synthesize data in a clearly communicative way, and when made user-friendly this information can inform stakeholders and other members of the public to address their needs. Whether it's widespread urban planning or improving traffic flow along a corridor, many evolving tools are helping transportation professionals conduct research and present it in an understandable and meaningful way.

Environmental Considerations of Sustainable Transportation

July 11, 2007

Sustainable energy practices in transportation means utilizing alternative modes and implementing alternative sources of energy that do not deplete resources or pollute the environment and can power part or all of the existing and future transportation infrastructure1. Goals of this bold venture include reducing emissions, air and water pollution, and dependency on non-renewable energy. Increasing efficient use of energy is another step toward a sustainable future.
