<![CDATA[The growing population at the IPB University Dramaga Campus has escalated daily private vehicle traffic, leading to gate congestion and excessive parking violations due to suboptimal public transportation. This study aims to evaluate the impact of population growth on campus traffic, assess shuttle bus performance, and formulate efficient management strategies to support a sustainable transportation master plan at IPB Dramaga Campus. Empirical data were gathered from historical records and field observations measuring load factor, circulation time, speed, and headway across the three corridors during peak and off-peak periods. Spatial connectivity, detour index, and route overlap were analyzed to design phased improvement schemes, including bus stop relocations (200–500 m) and route restructuring. The existing service exhibited suboptimal load factors (14.15%–41.66%), high route overlap between Corridors 1 and 2 (609.12 m; up to 41.25%), and limited carrying capacity, serving only 8.73% of the academic population at 70% capacity. Implementing an integrated optimization strategy—combining headway engineering on Corridor 1 (Scheme 3), stop adjustments on Corridor 3 (Scheme 2), and a linear routing alignment on Corridor 2—reduced cycle times and significantly improved operational efficiency. This integrated configuration increased the daily passenger carrying capacity to 5,691 passengers (18.20%) at 70% capacity and 6,840 passengers (21.88%) at 100% capacity. Optimizing circulation routes, eliminating unproductive turning loops, and restructuring designated bus stops can double campus shuttle bus service performance without major fleet additions. The proposed linear configuration provides an effective operational policy framework for sustaining the internal campus transit system.]]>
