A well-designed school environment fosters educational sustainability by enhancing student well-being and supporting eco-friendly practices. It ensures safer, more accessible learning spaces following SDG 4 and improves school-based community mobility, aligning with SDG 11. However, in Nakhon Pathom, school traffic congestion disrupts daily life, causing delays, air pollution, and pedestrian risks. Unlike developed areas with structured infrastructure, limited road networks and concentrated drop-off times create bottlenecks. This study applies the Design Thinking (DT) framework using a mixed-method approach to examine congestion at the Demonstration School of Silpakorn University (DSU), the largest university demonstration school in the western region. Traffic count data, stakeholder interviews, and field observations identify four peak traffic periods, with the most severe congestion occurring in the morning and afternoon. Quantitative analysis reveals high vehicle volumes at key intersections, particularly Si Yaek 50 Pi and the rear exit gate. Qualitative findings highlighted issues such as parent parking behavior, poor coordination with traffic authorities, and delivery vehicle congestion. Proposed solutions include redesigning parking areas, implementing one-way traffic systems, increasing traffic personnel, encouraging responsible parent behavior, and using traffic alert technology. Long-term strategies involve traffic regulation training for parents and raising awareness to promote responsible driving. As DSU prepares to relocate, a rise in traffic is expected due to the approximately 800 students and the nearby commercial zones. Assessing traffic flow at the new site is crucial. This transition offers a chance to design efficient infrastructure and foster collaboration with local agencies, ensuring sustainable school mobility solutions.
