Traffic Signal Systems and Regional Transportation Systems Management 2007

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2035 includes 23 papers that explore data-driven algorithms for coordinated traffic signal systems, precedence graphs for traffic signal operations modeling, coordinated traffic signals during transition, diamond interchanges at closely spaced intersections, advance preempt with gate-down confirmation for railroad grade crossings, video detection system impacts on signalized intersections, and genetic algorithm optimization of signal timings.  This issue of the TRR also examines the real-time prediction of delay and queue length at signalized intersections, lane-by-lane detection at actuated controlled intersections, dilemma zone design, actuated controller performance measures, detector configurations on high-speed approaches to traffic signals, interrelationship between passage time and detection zone length at intersections, empirical observations of dilemma zones, hardware-in-the-loop simulation, and light rail transit priority at grade crossings.  In addition, this TRR explores cycle length optimization, traffic signal transition strategies for exit preemption control, traffic simulation for decision support in real-time regional traffic management, opening the new Woodrow Wilson Memorial Bridge, uncertainty in benefit-cost evaluations of intelligent transportation systems, traffic operations for hurricane evacuation, and effects of toll strategies on route diversion and travel time.

Individual TRRs, which are published on an irregular basis throughout the year, consist of collections of peer-reviewed papers on specific transportation subject areas and modes.  TRB's TRR Online service allows all visitors to identify papers of interest and review abstracts of those papers.  Access to the full papers is available to service subscribers and employees of TRB sponsors.  Papers may also be purchased on an individual basis.

Printed copies of TRR Journals may also be purchased on an annual subscription basis.  Each year, TRB publishes approximately 45 volumes of the TRR Journal, containing more than 800 papers grouped by subject.
