RHODES is a traffic-adaptive signal control system that optimally controls the traffic that is observed in real time. The RHODES-ITMS Program is the application of the RHODES strategy for the two intersections of a freeway-arterial diamond interchange. This report addresses the latest phase of the RHODES-ITMS Program that resulted in a field-test in the City of Tempe, Arizona. In summary, this phase involved: (i) the integration of the RHODES logic within the signal controller, (ii) the validation of the RHODES logic using 'hardware-in-the-loop' simulation, (iii) the integration of the RHODES algorithms within Tempe's traffic management system, (iv) the deployment of RHODES for the field test and (v) the data gathering and evaluation of traffic performance 'with' and 'without' the RHODES logic. The objectives of this project were: (i) to see if a communication/computation infrastructure could be designed and implemented for second-by-second detector data collection and signal phase commands, (ii) to see if a traffic-adaptive signal control system could be implemented on an off-the-shelf Advanced Traffic Controller, (iii) to determine whether the RHODES strategy is viable in the field, and (iv) to evaluate the traffic performance of RHODES.
