Energy Analysis of Pumabús Routes for Optimization of an Electric Fleet in Ciudad Universitaria
General scope
Electromobility is a primary alternative for mitigating climate change, especially in urban passenger transport. In response, a methodology was developed to estimate emissions and determine the energy performance of a bus fleet in a controlled environment: the UNAM central campus. For emission quantification, the operational characteristics of current units were used, while electric-unit consumption was established from commercial specifications. The study seeks to technically and economically support scenarios that promote decentralization of pollutant emissions in the Valley of Mexico while improving transport quality.
Main results obtained
Applying the proposed methodology enabled energy storage sizing and operational cost evaluation. Through route characterization and identification of critical variables, a high-fidelity comparison with conventional diesel technology was conducted. The results showed a favorable economic scenario and supported the feasibility of the analyzed fleet. Annual GHG emissions were quantified, providing objective evidence of environmental mitigation, and consolidating zero-emission units as a strategic alternative within the evaluated context.
Methods used
To support the project's technical validity, CO2e emissions were estimated following Official Journal of the Federation (Diario Oficial de la Federación) guidelines, and vehicle range was projected through energy-balance equations. The economic assessment integrated CFE Distribution (DIST) tariffs with an updated market analysis. These variables, together with geospatial characterization and AVL CRUISE M simulations using system-specific driving cycles, enabled the final results.
Relevance of the topic
Modernizing the transport network is projected as an integral solution to maximize operational efficiency and minimize operating costs while prioritizing user demand. In response to global and local climate challenges, the transition to an electric fleet was structured to enable mitigation and decentralization of polluting emissions. This approach supports system viability while positioning the Pumabús network as a benchmark for sustainable mobility in the urban environment.
Main conclusions drawn
This transition was confirmed as a robust technical proposition for current operational demands. Emissions quantification demonstrated a competitive environmental advantage over the conventional framework, while the financial analysis projected a tangible reduction in operating costs. Additionally, the initial investment was analyzed as a key component for technology selection, charging infrastructure design, and technical support configuration to help ensure the profitability and success of the technological transition.
