CASE STUDY For more information regarding our transportation solutions, contact: Miguel de la Riva, PE, PTOE, Senior Traffic Engineer | 717-620-5963 U.S. Route Smart Traffic Signal System P RO B L E M US Route 15, in Lewisburg, Union County, PA, is a major arterial road and a critical part of the region’s transportation system, linking the Lewisburg area with Harrisburg to the south and I-80 to the north. Lewisburg is a primary commercial center and has the greatest population density in Union County. Motorists traveling along the corridor experience frequent traffic delays and congestion. Conse- quently, Lewisburg Borough in collaboration with East Buffalo Township and Pennsylvania Department of Transportation (PennDOT) Engineering District 3-0 retained Pennoni to provide engineering consulting services to address vehicular traffic congestion and pe- destrian safety by means of implementing an Adaptive Traffic Signal Control (ATSC) system on three signalized intersections along a portion of US Route 15. ATSC systems are capable of reducing congestion and improving safety without the need for more expensive and disruptive capacity-adding improvements, such as new traffic lanes. 16 | P E N N O N I
