| Summary | Signal subnetwork determination is one of the most important steps of signal timing design. In most cases, two adjacent subnetworks do not have the same optimal cycle lengths by their individual traffic characteristics. Such signal timing plans can only reflect internal coordination for specific signal subnetwork without concerning the overall road system performances. The phenomenon easily results traffic congestion by unsuitable coordination at the interfacing intersections. This research considers minimum delay based on maximum progression by sequential design process. The operation performances are conducted by dual arrival rate, dual saturation flow rate and over saturation conditions for delay calculations and “Progression Possibility” for progression effects, respectively. This paper presents two case studies to promote understandings of this approach. Traffic engineers can apply the offset design concept for signal subnetwork interfaces to increase overall performances of integrated signal networks. |
