Determining ergonomics-based sustainability for public utility vehicles: integrating higher-order structural equation...

Area of Science:

• Environmental Science
• Transportation Engineering
• Human Factors Engineering

Background:

• Public utility vehicles (PUVs) face challenges in balancing environmental, social, and economic sustainability.
• Enhancing commuter and driver well-being is crucial for sustainable transportation systems.

Purpose of the Study:

• To develop an integrated Ergonomics-based Sustainability (EBS) framework for PUVs in the Philippines.
• To identify key factors influencing EBS in PUVs using advanced analytical methods.

Main Methods:

• Integration of higher-order structural equation modelling (H-SEM) for holistic analysis.
• Application of the random forest classifier (RFC) for identifying immediate operational priorities.
• Analysis of 350 survey responses from PUV stakeholders.

Main Results:

• Environmental sustainability (pollution reduction, energy efficiency) emerged as the most influential factor.
• Social dimensions, including driver well-being and vehicle safety, were critical.
• Economic factors played a supporting role, with RFC highlighting immediate safety and usability concerns.

Conclusions:

• The study provides a data-driven framework for improving PUV ergonomics and sustainability.
• Findings support policymakers and planners in enhancing commuter satisfaction and promoting sustainable mobility.
• The developed EBS framework demonstrates adaptability for global applications.
