The Pushkaralu festival, a major Hindu event held every twelve years, is set to focus on the Godavari River and Rajahmundry in 2027. As a tier-3 city, Rajahmundry faces a daunting challenge: accommodating an estimated 80 million pilgrims over just 12 days. The influx is giving rise to immense pressure on major modes of transport systems such as railways, buses, and air travel necessitating a critical assessment of infrastructure readiness. This paper employs a multi-modal stress analysis to evaluate current capacities and forecast demand across transport systems. The method involves a layered process. Firstly, the demand is projected across each mode. Later, the performance of the current infrastructure in theory is examined. Findings reveal significant gaps: The city’s railway platform capacity proved inadequate, and bus fleets risk being overwhelmed. However, the airport currently undergoing upgrades may meet projected needs. More than just a case study, this research offers a scalable planning framework for other cities preparing for religious mega-events. By identifying infrastructure stress points in advance, urban planners can better manage crowd movement and ensure safety and efficiency during high-impact events.
