Can signal interconnection improve congestion on PA 23 in the long term?
There are currently 23 signalized intersections along PA 23 from US 30 to US 322. Based on the unique characteristics of the PA 23 corridor described above, the benefits of traffic signal coordination that might be achievable elsewhere are not anticipated to be achievable along PA 23 with future traffic volumes. Historically, there has been linear development along PA 23, and input received from stakeholders indicates that this linear development pattern is preferred for the future. Therefore, it is highly probable that several more signals will be required on PA 23 in the coming years as that development occurs. Overall, more diversion of traffic to side roads to avoid traffic congestion on PA 23 is expected in the future, even if some of the added signals may improve traffic flow.
