Buses are the most popular and common passenger vehicle for long distance travel in Malaysia. Increased bus usage as a public transport prompts researchers to study safety aspects of the vehicles subjected to various crash incidents. The most damaging bus accident is rollover crash. The bus structures must have sufficient crashworthiness and strength in order to reduce and prevent injuries and fatalities during the rollover accident. Initially, this paper overviews the current status of rollover accidents and requirement of UN-ECE Regulation 66 which is aimed to improve the bus structure in withstanding the rollover crash. The current bus framework structure comprises galvanized square hollow sections (SHS) which are welded and bolted together. Abaqus was used to simulate responses of bus structure subjected to loadings as specified in UN-ECE Regulation 66. The results showed that the gap allowances of the residual space are complied with the UN-ECE R66 requirements. Further work to optimize the bus structure in terms of weight, structural strength and crashworthiness is proposed.

As policymakers and automotive stakeholders around the world seek to accelerate the electrification of road transport with hydrogen, this study focuses on the experiences of Germany, a world leader in fuel cell technology. Specifically, it identifies and compares the drivers and barriers influencing the production and market penetration of privately-owned fuel cell electric passenger vehicles (FCEVs) and fuel cell electric buses (FCEBs) in public transit fleets. Using original data collected via a survey and 17 interviews, we elicited the opinions of experts to examine opportunities and obstacles in Germany from four perspectives: (i) the supply of vehicles (ii) refuelling infrastructure, (iii) demand for vehicles, and (iv) cross-cutting institutional issues. Findings indicate that despite multiple drivers, there are significant challenges hampering the growth of the hydrogen mobility market. Several are more pronounced in the passenger FCEV market. These include the supply and cost of production, the lack of German automakers producing FCEVs, the profitability and availability of refuelling stations, and low demand for vehicles. In light of these findings, we extract implications for international policymakers and future studies. This study provides a timely update on efforts to spur the deployment of hydrogen mobility in Germany and addresses the underrepresentation of studies examining both buses and passenger vehicles in tandem.
