| Resource Title | Assessing the Impacts of Various Fleet Replacement Strategies on Air Quality and Health using AERMOD Dispersion Model – The Case of Trece Martires City, Cavite |
| Date Issued | 13 October 2025 |
| Abstract | This study assessed the potential air quality improvements resulting from the electrification of public and private transport in Trece Martires City, Cavite. Using AERMOD, various scenarios were simulated to analyze the effects of modernization strategies on PM₂.₅ and related pollutant concentrations. Emission estimates were based on local traffic composition, vehicle-specific emission factors, and road geometry. The model was validated by comparing simulated PM₂.₅ concentrations under the Business-as-Usual (BAU) scenario with observed monitoring data, showing acceptable agreement. Initial scenarios focused on public transport, evaluating Euro 4-compliant jeepneys, electric jeepneys, and electric tricycles. Full electrification of both jeepneys and tricycles (ETEJ) resulted in a 46.42% reduction in PM₂.₅ and slight improvement in AQI, though it remained in the “Unhealthy” range. Recognizing the contribution of private vehicles, particularly motorcycles, additional scenarios explored partial fleet electrification. The EPV50 scenario, involving 50% electrification of cars and motorcycles, achieved a 70.49% PM₂.₅ reduction and improved AQI to “Moderate.” Even 20% electrification shifted AQI to “Unhealthy for Sensitive Groups,” indicating notable health benefits. Overall, findings highlight that while public transport modernization is essential, including high-emitting private vehicles in clean transport strategies yields more substantial and sustainable improvements in urban air quality. |
