RHODES PROJECT: PHASE II(A). FINAL REPORT

This report documents the work performed on the RHODES Project Phase II(a). This research effort was the continuation of the RHODES Project Phase I. Phase I explored concepts for models and algorithms for a real-time traffic-adaptive control system for street networks, referred to as the RHODES System. Phase II(a) focused on further development of some of these algorithms and on performing some preliminary laboratory experiments with these algorithms using simulation models. The control architecture of RHODES is based on a hierarchical decomposition of the overall traffic control problem. In an aggregate sense, there are three levels in the control hierarchy: network load control, network flow (platoon) control, and intersection (vehicular) control. RHODES architecture allows for a modular implementation of many of the subsystems within the control structure and the incorporation of IVHS technologies (e.g., new vehicle sensors) when they become available. In Phase II(a), the decision problems at each of the hierarchical levels were further analyzed and the decision model/algorithm at the intersection level was explicitly formulated, solved, and evaluated using simulation models.
