In recent years, the number of vehicles on the road has increased significantly, but the road infrastructure and traffic systems have not kept pace. This imbalance led to frequent traffic congestion, long vehicle queues, and increased risks for pedestrians, especially in busy areas of Tuguegarao City. During peak hours, the interaction between vehicles and pedestrians, particularly at street-level crossings, often resulted in delays and safety
concerns.

This study explored a practical solution: pedestrian overpasses. While commonly seen in larger cities, their actual impact in smaller urban areas like Tuguegarao has not been thoroughly assessed. The research focused on three high-traffic locations-Carig Integrated School, University of Cagayan Valley, and SM City Downtown-to examine how pedestrian overpasses could improve traffic conditions and pedestrian movement. Microsimulation modeling was used to recreate traffic and pedestrian scenarios during morning and afternoon peak hours, both before and after introducing the overpasses. The analysis considered vehicle delays, queue lengths, stop delays, and pedestrian level of service (LOS).

The findings showed clear improvements. Traffic queues got much shorter-only 44.6 meters at Carig, 51.2 meters at UCV, and 36.4 meters at SM City. Vehicle delays also dropped drastically, down to just a few seconds. The Level of Service, which rates how well traffic flows, improved from the worst grade (F) to excellent levels-A at Carig and SM City, and B at UCV. Pedestrian travel times stayed nearly the same, but their overall experience improved a lot. With the overpasses, pedestrians no longer had to wait for cars to stop or risk crossing in traffic. The Level of Service for pedestrians jumped from C to A, showing that the walk was not only safer but also more relaxed and predictable. These results demonstrated that pedestrian overpasses had a positive impact not just on vehicles, but on the overall urban experience.

This study also supported several Sustainable Development Goals (SDGs). It contributed to SDG 11: Sustainable Cities and Communities by promoting better pedestrian infrastructure, to SDG 3: Good Health and Well-being by improving road safety, to SDG 9: Industry, Innovation, and Infrastructure through the use of simulation-based planning, and to SDG 13: Climate Action by potentially reducing vehicle emissions through improved traffic flow.

In conclusion, installing pedestrian overpasses made everyday travel in Tuguegarao City more efficient, safer, and more convenient. These structures offered a simple yet effective way to improve both traffic systems and urban livability.
