Abstract

Bus accidents continue to contribute significantly to global transportation fatality statistics, particularly in developing countries where human factors and infrastructure conditions play a major role. A comprehensive synthesis of bus superstructure crashworthiness technologies is presented by tracing their evolution from basic regulatory compliance toward the challenges of future technological adaptation. While the UN ECE R66 standard has established a well-defined framework for rollover protection, a review of the literature reveals a substantial gap in frontal impact standards, leading to the adoption of truck regulations (UN ECE R29) that are often incompatible with the flat-front geometry of buses. The discussion focuses on recent findings related to validated virtual testing methodologies, innovative structural reinforcement strategies such as seat-to-pillar integration, and the critical role of occupant restraint systems in mitigating secondary injuries. Furthermore, the transition toward electric buses is identified as introducing new challenges associated with high-voltage battery protection and the brittle failure characteristics of lightweight composite materials. It is concluded that future safety paradigms must evolve beyond merely preserving occupant survival space toward a holistic approach that integrates structural optimization, occupant biomechanics, and energy storage system protection.

Abstract

Competency in Computer-Aided Design (CAD) 3D–based design is a vital foundation in modern vocational engineering education. However, a major challenge in practice is the lack of uniform competency standards among teaching staff, where intuitive modeling practices are often found that are not fully defined, resulting in low design data integrity. This program aims to standardize such technical competencies through intensive training based on the Certified SolidWorks Associate (CSWA) curriculum. The program was conducted entirely in an offline setting over 65 instructional hours, covering fundamental topics ranging from design intent philosophy and parametric sketching to assembly validation using standard mates. The results demonstrate a perfect quantitative outcome, with 100% of participants successfully passing the examination and obtaining the international CSWA certification. This success indicates that structured training interventions are effective in equalizing participants’ competencies. The strategic implication of this program is the establishment of a uniform teaching standard among vocational lecturers, which ultimately ensures that graduates possess digital design literacy aligned with modern industrial best practices.
