SIMULATION AND CONTROL OF TRAFFIC ON A DIAMOND INTERCHANGE

Signaling strategies that control left-turning traffic on a demand interchange are evaluated by simulation. Although the simulation and control strategies were designed for a particular interchange, each may be adopted to the intersection of other one-way pairs of arterials. The simulation method is briefly discussed, and four related control strategies are presented. Evaluation of these strategies based on average and maximum transit times through the interchange indicates that choosing signal features can significantly profit from the use of short-term average volume information. A flexible strategy based only on queue lengths gives good but not entirely satisfactory performance.
