As Hill & Smith Infrastructure commemorates 200 years of delivering infrastructure and property safety in the UK, we reflect on the significant milestones achieved and the advancements that have shaped the nation’s transportation infrastructure. From the early days of horse-drawn carriages to the modern era of high-speed motorways, the evolution of road safety has been driven by innovation, regulation, and an unwavering commitment to protecting road users. Among the myriad of safety measures developed over the years, Vehicle Restraint Systems (VRS) have emerged as a critical component in mitigating accidents and saving lives. This article delves into the historical journey of delivering road safety in the UK and underscores the pivotal role of VRS in ensuring safer roads for all.

The Early Days: From Turnpikes to the Motor Age

The inception of structured road safety in the UK can be traced back to the early 19th century with the establishment of turnpike trusts. These organisations were responsible for maintaining and improving major roads, funded by tolls collected from road users. As road usage increased, so did the need for better road surfaces and safety measures. The advent of macadamized roads, developed by John McAdam, marked a significant improvement in road quality, reducing accidents caused by poor road conditions.

As Hill & Smith Infrastructure began its journey, it witnessed the Industrial Revolution and the subsequent rise of motor vehicles. The UK faced new challenges in road safety, and the Motor Car Act of 1903 introduced measures such as vehicle registration and driving licenses, aiming to regulate the burgeoning number of automobiles and enhance safety. However, it was not until the mid-20th century that road safety became a national priority, leading to the development of more sophisticated safety infrastructure.

The Rise of Road Safety Initiatives

The post-World War II era saw a dramatic increase in road traffic, necessitating comprehensive safety measures. The introduction of speed limits, pedestrian crossings, and traffic lights were some of the early interventions aimed at reducing accidents. In 1946, the first zebra crossing was introduced in Slough, providing a safer way for pedestrians to cross busy roads.

The formation of the Ministry of Transport in 1919 marked a significant step towards centralised road safety management. The ministry’s efforts culminated in the Road Traffic Act of 1930, which included provisions for mandatory insurance, driving tests, and speed limits for certain vehicles. These measures laid the groundwork for modern road safety regulations.

The Advent of Vehicle Restraint Systems

As road networks expanded and vehicles became faster and heavier, the need for robust safety barriers became apparent. The development of Vehicle Restraint Systems (VRS) in the latter half of the 20th century revolutionised road safety, with Hill & Smith Infrastructure playing a crucial role in this evolution by contributing to the design and implementation of advanced VRS technologies.

Early Innovations in VRS

Today, VRS technology has evolved to include a wide range of solutions tailored to different road environments and vehicle types with  modern VRS engineered to address specific safety challenges. Hill &  Smith Infrastructure has been at the forefront of these advancements, offering solutions such as:

  • Energy-Absorbing Barriers: These systems are designed to absorb kinetic energy during a collision, reducing the severity of impact for vehicle occupants. Examples include cable barriers and crash cushions.
  • High-Containment Barriers: Used in high-risk areas such as bridges and tunnels, these barriers provide maximum resistance to vehicle penetration, preventing vehicles from breaching the barrier and causing secondary collisions.
  • Low Carbon Barriers: Comprising less steel and concrete, and incorporating a low carbon mix, these barriers cut CO2 emissions by half compared to standard products. 

The ongoing advancements in VRS technology highlight the continuous efforts to enhance road safety, ensuring that as vehicles and road networks evolve, the protective measures in place are equally progressive and effective.

The first VRS were rudimentary, often consisting of simple guardrails or wooden posts. However, as the understanding of crash dynamics improved, more sophisticated systems were developed. The introduction of the steel guardrail in the 1950s provided a more effective solution, capable of withstanding higher impact forces and redirecting errant vehicles back onto the road.

Evolution of VRS Products

Since the 1970’s when Hill & Smith began manufacturing the very first UK tested restraint systems on the market, the company has been at the forefront of contributing to road safety with various products. These have included: 

  • Steel Barriers: Introduced in the mid-20th century, these barriers have been essential in redirecting vehicles and reducing the severity of crashes. Their durability and effectiveness in absorbing impact have made them a standard choice for many roadways.
  • Concrete Barriers: Known for their high containment capabilities, concrete barriers are commonly used in high-risk areas like highways and construction zones. They offer robust protection by preventing vehicle penetration and providing maximum resistance to high-impact collisions.
  • Crash Cushions: These energy-absorbing devices are placed in front of fixed objects such as bridge supports and poles. Crash cushions help to reduce the severity of impacts by absorbing kinetic energy, thereby protecting vehicle occupants from severe injuries.
  • Parapets: Installed on bridges and elevated roadways, parapets are rigid barriers designed to prevent vehicles from falling off the edge. They provide high containment and structural integrity, ensuring the safety of both vehicles and pedestrians.
