Mobility transition

Mobility transition is a physics 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 Mobility transition rather than just read about it. In short: Mobility transition is a set of social, technological and political processes of converting traffic (including freight transport) and mobility to sustainable transport with renewable energy resources, and an integration of several different modes of private transport and local public transport. It also includes social change, a redistribution of public spaces, and different ways of financing and spending money in ur…

Key takeaways

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

Reference excerpt

Mobility transition is a set of social, technological and political processes of converting traffic (including freight transport) and mobility to sustainable transport with renewable energy resources, and an integration of several different modes of private transport and local public transport. It also includes social change, a redistribution of public spaces, and different ways of financing and spending money in urban planning. The main motivation for mobility transition is the reduction of the harm and damage that traffic causes to people (mostly but not solely due to collisions) and the environment (which also often directly or indirectly affects people) in order to make (urban) society more livable, as well as solving various interconnected logistical, social, economic and energy issues and inefficiencies. Mobility went through many transitions in the 19th and 20th centuries. Canal boats, Steam railways and bicycles largely replaced journeys afoot and by horse, and steamships replaced sailing ships. Each later changed to internal combustion engines and, in the case of many railways, electricity. They in turn were partly replaced by automobile transport and aviation.

Motivation

Environmental damage An important goal is the reduction of greenhouse gas emissions such as CO2. To achieve the goal set in the Paris Agreement, that is, to restrict global warming to clearly below 2 °C, the burning of fossil fuels is to be discontinued around 2040. Because the CO2 emissions of traffic practically need to be reduced to zero, the measures taken so far in the transport sector are not sufficient in order to achieve the climate change mitigation goals that have been set.

Air pollution A mobility transition also serves health purposes in the metropolitan regions and large cities and is intended in particular to counteract the massive air pollution. For example, in Germany in 2015, traffic caused about 38% of human-related nitrogen oxide emissions. According to Lelieveld et al. (2015), air pollution from land traffic alone killed around 164,000 people in 2010; in Germany alone, it was over 6,900 people. A 2017 study by the same lead author concluded that air pollution from road traffic in Germany causes 11,000 deaths every year that could potentially be avoided. This figure is 3.5 times the number of fatalities from accidents.

To demonstrate how much road traffic contributes to air pollution in Germany, for every 100 inhabitants, 58 of them owned passenger cars, according to Federal Statistical Office of Germany.

Accident fatalities, quality of life, aggressive behaviour Further motives for the mobility transition are the desire for less noise, streets with quality of life and lower accident risks (see also Vision Zero). According to estimates by the European Environment Agency, 113 million people in Europe are affected by road noise at unhealthy levels. With increasing traffic and commuter numbers, many citizens also wished for more attractive places to spend time in public spaces. A mobility transition therefore also serves to increase the quality of life. The mobility transition is also seen by some as a means of reducing aggressive behaviour in traffic (road rage) and in society. Studies indicate that people in large and expensive cars are more likely to behave recklessly. According to the German Verkehrsklima 2020 (Traffic Mood 2020) study, women feel more insecure in traffic than men, and they want more controls and stricter laws. On the other hand, the "evil eye" design of vehicles is increasingly used by manufacturers to sell vehicles to drivers who want to feel strong and superior on the road. Accident reporting by the press and the police sometimes paints a distorted picture.

Traffic congestion Traffic congestion has been increasing in streets and roads. Traditional traffic policy usually relies on expanding the roads to solve the congestion problem. Worldwide, the main causes are urbanisation and the purchase of more automobiles as prosperity increases. A return to more public and non-motorised transport is likely in the future.

Peak oil

Petroleum production is approaching its peak, or by some estimates may already have been passed in the 2020s. The Earth's oil reserves are finite, and oil extraction will become inadequate to power as many petroleum-fueled vehicles. Researchers have proposed changing to transport that uses less fuel.

Worked examples

Example 1 — a first encounter with Mobility transition

Start with the simplest possible case. Write down what Mobility transition claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Mobility transition 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 Mobility transition 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 Mobility transition

In research
Mobility transition appears in physics 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 Mobility transition 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
Mobility transition is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy policy, Environmental policy, Sustainability, so understanding it makes those chapters shorter.
In everyday life
Look for Mobility transition 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.
