REAL-TIME DECISION-MAKING ALGORITHM FOR DIAMOND INTERCHANGES

Due to the complexity of traffic movements occurring within urban interchanges and increasing levels of demand, many diamond interchanges are experiencing serious congestion. Unfortunately, today's industry-standard control hardware and intersection timing practices do not always allow for optimum performance. In response to this need for improved, condition-responsive traffic control, the "Smart" diamond project has been underway at the Texas A&M ITS Research Center of Excellence. The Smart project uses video imaging equipment to provide input to a VMEbus unit containing processor, memory, and input/output cards. The VMEbus stores and analyzes the traffic descriptive data and produces optimal settings for a diamond interchange controller and for lane assignment signs that control the use of space within the interchange.
