Swedish researchers at Chalmers University of Technology have revealed a groundbreaking truck front design aimed at drastically reducing car-truck collision risks.

This latest development comes as a response to recent revisions in European Union regulations, which have enabled the implementation of potentially life-saving changes in truck design.

Lowering the Risks of Truck-car Collisions

Truck-car collisions have long been a concern due to the disproportionate danger they pose to car occupants. Statistics reveal that between 14-16% of all car occupant fatalities in both the EU and the US involve heavy goods vehicles (HGVs).

Alarmingly, car occupants are the victims in 90% of these incidents. The sheer mass, geometry, and stiffness of large trucks amplify crash severity, often leading to devastating consequences for those in passenger vehicles, even at moderate speeds.

The new truck front design from Chalmers University of Technology focuses on a crucial aspect - protecting the passenger car cabin during head-on collisions. Traditional truck designs have not addressed this issue adequately, prompting researchers to rethink how trucks and cars interact in crashes.

Adding Critical Safety Features to Truck Fronts

This innovative design incorporates features such as an energy-absorbing aluminum honeycomb structure, which is designed to distribute and reduce impact forces.

Thanks to relaxed EU regulations concerning truck lengths, designers now have greater flexibility to integrate such safety features. Additionally, efforts are underway to optimize the truck's front further, aiming to deflect cars away from the truck's forward path and enhance overall safety measures.

Tests conducted by the Swedish Transport Administration have yielded promising results, demonstrating a 30-60% reduction in passenger car compartment deformations with the new truck front.

Deadly Truck-related Accidents

In addition to the innovative truck front design, attention has been drawn to alarming statistics regarding truck-related accidents. In 2021 alone, 5,700 large trucks were involved in fatal crashes, marking an 18% increase from the previous year.

Despite representing only 9% of all vehicles involved in fatal crashes, large trucks accounted for 10% of total vehicle miles traveled. Moreover, 117,300 large trucks were involved in injury crashes in 2021, highlighting the urgent need for improved safety measures.

Looking ahead, Trafikverket aims to incorporate crash tests for trucks into Euro NCAP consumer tests by 2030, while Euro NCAP plans to commence safety testing of trucks, including crash tests, from 2024 onwards. These initiatives reflect a concerted effort to enhance road safety and mitigate the devastating impact of truck-related accidents on global roadways.

With continued research, collaboration, and innovation, the new truck front design from Swedish researchers offers hope for a future where road travel is safer for all motorists.
