The document outlines a SAVi assessment for a proposed MRT system in Pampanga, Philippines, consisting of four bus rapid transit (BRT) lines and one light rail transit (LRT) line. It employs system dynamics modelling and causal loop diagrams to compare a 'no action' scenario against the MRT implementation, identifying potential co-benefits such as reduced CO2 emissions, decreased traffic congestion, and increased regional connectivity. The assessment provides a detailed set of assumptions and data sources for calculating capital costs, operational revenues, and avoided costs related to health, accidents, and fuel use.

The assessment finds that the proposed MRT system in Pampanga, consisting of four bus rapid transit lines and one light rail transit line, provides significant societal value. While traditional benefit-to-cost ratios (BCR) suggest the project is not investment-worthy at 0.62 or 0.63, the sustainable BCR (S-BCR) is 1.72. Over a 30-year period from 2023 to 2053, the project is estimated to generate a cumulative discounted net benefit of PHP 360.3 million (USD 6,402 million). The most significant impacts are the avoided costs of traffic accidents (PHP 239.7 million), time savings (PHP 182,367 million), and avoided vehicle operating costs (PHP 109,988 million).
