Transport Research Laboratory

Transport Research Laboratory is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Transport Research Laboratory rather than just read about it. In short: TRL Limited, trading as TRL (formerly Transport Research Laboratory) is an independent private company offering a transport consultancy and research service to the public and private sector. Originally established in 1933 by the UK Government as the Road Research Laboratory (RRL), it was privatised in 1996.

Key takeaways

Transport Research Laboratory belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Transport Research Laboratory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Transport Research Laboratory from memory before moving on to harder problems.

Reference excerpt

TRL Limited, trading as TRL (formerly Transport Research Laboratory) is an independent private company offering a transport consultancy and research service to the public and private sector. Originally established in 1933 by the UK Government as the Road Research Laboratory (RRL), it was privatised in 1996. Its motto or tagline is 'The Future of Transport'.

History TRL was originally established in 1933 by the UK Government as the Road Research Laboratory (RRL) under the Department of Scientific and Industrial Research (DSIR), and later became the Transport and Road Research Laboratory (TRRL) in 1972. During the Second World War, the Laboratory contributed to the war effort. Among its contributions, under William Glanville, were research that aided the development of plastic armour, the bouncing bomb and the Disney bomb. During governmental reorganisation in the 1970s, the TRRL moved from the Department of Trade and Industry (DTI) to the Department of the Environment (DoE). At the TRRL, Frank Blackmore developed the mini-roundabout and its associated 'priority rule', which was adopted in 1975. With the encouragement of the UK Department of Transport, TRRL was instrumental in promoting cooperation with other European laboratories. In 1989, TRRL's initiative to create a Forum of European National Highway Research Laboratories led to its hosting of the inaugural meeting. It became an executive agency of the UK Department for Transport (DfT) in 1992, and changed its name to the Transport Research Laboratory (TRL). It was privatised in 1996, though earlier plans in 1994 for a proposed privatisation were criticised at the time, notably by former Transport Minister Barbara Castle.

Operations TRL is based in Crowthorne, Berkshire, with additional offices in Edinburgh and Birmingham. TRL's key areas of work include road, network and vehicle safety; traffic management; planning and control; investigations and risk management; transport infrastructure; and environmental assessment, including work on climate change, noise and air pollution.

Software TRL has produced industry-standard software including Junctions, TRANSYT, SCOOT 7 and UTC, Powered by SCOOT 7.

Site redevelopment The extensive Crowthorne site has been substantially scaled back, with many of the original buildings disused, creating an opportunity for redevelopment. In 2012, Bracknell Council identified the original site as a strategic area, suitable for a new mini-town of 1,000 homes.

Corporate affairs To maintain its commercial independence and impartiality, TRL is owned by the Transport Research Foundation (TRF), a non-profit distributing foundation, overseen by 80 sector members from the transport industry. The TRF is classed as a non-profit distributing organisation (NPDO), a form of business structure where all profits are reinvested in services or business growth, rather than being distributed to shareholders. TRL's profits are invested in its own research programmes, selected by the TRF to enhance knowledge in critical areas such as safety, environmental impact and sustainable development.

Worked examples

Example 1 — a first encounter with Transport Research Laboratory

Start with the simplest possible case. Write down what Transport Research Laboratory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Transport Research Laboratory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Transport Research Laboratory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Transport Research Laboratory

In research: Transport Research Laboratory appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Transport Research Laboratory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Transport Research Laboratory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 establishments in the United Kingdom, Companies based in Berkshire, Engineering research institutes, so understanding it makes those chapters shorter.
In everyday life: Look for Transport Research Laboratory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
