SIMULATING TRAFFIC FLOW


Janice DanielsJanice Daniel, associate professor of civil and environmental engineering, uses mathematical analyses and computer simulations to try to improve traffic conditions on New Jersey's roads. Recent studies have looked at factors contributing to truck accidents; bottlenecks causing congestion at the ports of Newark and Elizabeth; and ways to make commuting by bus safer and more efficient.

She is currently studying bus nubs -- extensions of sidewalk at bus stop corners that allow buses to stop in the traffic lane without risk to passengers -- and the effectiveness of traffic signal priority, in which buses always get a green light to minimize delays in bus transportation. Edward Lieberman, president of KLD Associates, of Huntington Station, N.Y., and Raghavan Srinivasan, of the University of North Carolina Highway Safety Research Center, are partners in the signal study.
