| Summary: | adjustments in the phase length, phase sequence, and lane always optimal. The two most widely used strategies, three- assignments. It was determined that the P30M was not assignments. Utilizing the TexSIM traffic simulator, the conditions, however, none of the available strategies is diamond interchange by changing the phase order and the lane during certain traffic conditions. This research focused on expert system, also known as the PASSER III Optimization hours. There were three different versions of the P30M that interchanges. Due to the different geometric and traffic it occasionally over-reacted in an attempt to catch up. Most Manager, or P30M, was tested to determine how well it NEMA controller switch from three to four-phase control. of the time, however, the P30M operated effectively by operated under changing traffic conditions. To evaluate the P30M, an interchange in Austin, Texas was modeled for two phase lengths, phase order, lane assignment, or all three. phase, and four-phasewith-two-overlaps, each have limitations reacting rapidly enough to the changing conditions, and that reducing delay and queue lengths. Some of the limitations of the controller and attempting to make a standard eight-phase the development of a prototype expert system to monitor the p3OM may have been contributed to the communications with The results indicated that the P30M can effectively control a There are many signal timing strategies for diamond traffic conditions at a diamond interchange and make were tested to determine if it was more beneficial to change |
