Key takeaways

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

Reference excerpt

ioki is a German technology company specialising on digital services and products for public transport with its headquarters in Frankfurt. ioki is an acronym for Input Output Künstliche Intelligenz (Input Output Artificial Intelligence). ioki provides digital services for public transport such as a ridepooling platform, data-based transport planning and a navigation system for bus drivers. While the majority of services is currently still provided in the DACH region, the company's product and service offering is also growing in Italy, Spain, France and the United Kingdom. ioki's clients include cities, public transport companies, school districts, government entities and private organisations.

History ioki was founded in 2017 as a corporate startup of the Deutsche Bahn — Germany's main railway company — to focus on and drive forward autonomous public transport. Over the years, the product portfolio and services expanded and led to an integrated focus on digitalisation and accessibility. In October 2017, the first autonomous bus line on public roads in Germany was launched in the Lower Bavarian spa town Bad Birnbach with ioki's operating system. The company launched ioki Hamburg, one of the oldest and most successful demand-responsive transport services in Germany. ioki collaborated with the Verkehrsbetriebe Hamburg Holstein (VHH) to create a shuttle that transports passengers around the clock in electric vehicles. It was later renamed hvv hop. The service started with ten vehicles and has grown since its launch. In 2019, ioki and Verkehrsbetriebe Hamburg (VHH) won the Deutscher Mobilitätspreis (German Mobility Award) for the ioki Hamburg project. Since then, various on-demand projects all over Europe have been set in motion. In February 2024, ioki and the teledriving start-up Vay announced their partnership to realise the first remotely driven on-demand service in public transport.

Activities ioki is a software-as-a-service and technology company. The ridepooling and routing platform from ioki is suitable for both driver-based and autonomous transport. The platform is intended to create carpools and combine the booked trips into optimised routes. It consists of an administration tool for the operator, the vehicle app, and the customizable passenger app. To optimise public transport, ioki uses data-based mobility analyses to identify the population's needs in the respective service area and enables assessment of the local mobility situation. The company recently added a navigation system that specialises in bus navigation and consists of a web version for route management and a navigation app for the driver. ioki is member of several organisations and networks to promote digital and autonomous mobility, such as SAAM (Swiss Association for Autonomous Mobility) and PAVE Europe. As of April 2024, the company reached 5 million passengers on the platform.

Worked examples

Example 1 — a first encounter with Ioki

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

In research: Ioki appears in computer science 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 Ioki 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: Ioki is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Frankfurt, Public transport in Germany, Self-driving car companies, so understanding it makes those chapters shorter.
In everyday life: Look for Ioki 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.

Frequently asked questions

What is Ioki in simple terms?

Why does Ioki matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Ioki?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
