Reference excerpt

GEWI is a German software company founded in 1992 by Hagen Geppert and Karl Will, headquartered in Bernburg, Germany. The company name is formed from the first two letters of the surnames of its founders - Geppert and Will. GEWI develops traffic and travel information software, with its main product, the Traffic Information Center (TIC), used in 31 countries for applications including real-time navigation data, road incident management, and traffic news broadcasting. The company operates through two entities: GEWI Europe, based in Germany with offices in Bernburg and Leipzig, and GEWI North America, based in Sugar Land, Texas.

GEWI Business

The company consists of two corporations: GEWI Europe based in Germany with offices in Bernburg and Leipzig. Hagen Geppert serves as Worldwide CEO. GEWI North America is located in Sugar Land (Houston) Texas and managed by North America CEO Jim O'Neill. Additional offices are located in the UK and USA. GEWI has a global customer base and has been ISO 9001 certified for quality standards annually since 1997, and is currently certified ISO 9001:2008.

TIC Product After its first generation of traffic data products, known as TMC Office, the company renamed the product to TIC (Traffic Information Center). TIC is a fully commercial off-the-shelf product (COTS) that customers can use to avoid problems associated with custom builds. Today, TIC is in its fourth generation and is used in 31 countries worldwide for a wide range of projects including traffic and travel information services (can include meteorological weather information), RDS-TMC, TPEG (over HTTP or digital broadcast such as DAB), navigation system testing (used by many device and car manufacturers), traffic news for radio (structured news reports auto-generated as ready by announcers), data harmonization and exchange, parking information, work zones (such as road construction), radio data using PAD (program associated data with station names, schedules, and music titles) and connected vehicles.

Markets The TIC Software is used by customers in commercial and government markets for a variety of traffic and travel related projects including:

Traffic and Travel Information Services TIC can be used to collect and create a wide variety of data including traffic incidents, travel events, weather conditions, parking availability and pricing, and many more. TIC allows data to be manually created by operators entering information using an easy-to-use dialog with drop-down lists, maps, and quick auto-completion. Data can be created using the TIC Client application on computers, iPad, or over internet connections. Data can also be automatically created from other data, for example, traffic and travel event data from traffic flow data

Road Incident Management In 2015, GEWI added Road Incident Management (RIM) to the TIC Product features. The TIC Product feature Road Incident Management provides a method to integrate this information and allow agencies to manage road incidents (as well as traffic incidents), and to keep the public informed with accurate and updated traffic and travel information. The TIC Product feature Road Incident Management provides a method to integrate this information and allow agencies to manage road incidents (as well as traffic incidents), and to keep the public informed with accurate and updated traffic and travel information. TIC can be used to define and track pre-agreed incident response plans, providing operators with a step by step process to properly respond to traffic and roadway issues. By using TIC to track the response, each action is recorded, allowing for a full review of the implementation and timing of the response, in order to measure how well the incident was handled, and whether any improvements to the response could be made. If the incident involves roadway infrastructure, such as road sensors or VMS signs, the status of each can be recorded as well, down to and including road surface conditions (from weather sensors) to better understand how an incident developed and on review, what could be done to prevent a reoccurrence. TIC can be used to help support agency services such as ATIS (Advanced Transport Information Systems), and eCall, a European initiative being launched in 2018 for new vehicles. A RIM video produced by GEWI which provides further details is available.

Real-time Information for Navigation TIC can be used to collect and create traffic and travel messages that can be broadcast as Traffic Message Channel (TMC) messages with or without encryption over FM using the Radio Data Channel (RDS), or distributed over the Internet using connected services. TIC can regionalize and prioritize TMC messages, and can also be connected to RDS encoders at FM transmitter sites using the standard protocol UECP, as well as to FM receivers for RDS-TMC service monitoring. Additionally, many car and navigation device manufacturers are able to provide more than just traffic and travel event information. They may also provide information about traffic flow, such as traffic speed, weather, and parking. This enhanced information is provided using TPEG, either broadcast or for an interactive driver experience with connected vehicle services, by using internet connections. TIC can be used to collect and create traffic and travel event data, as well as collect traffic flow data such as speed and volume, all referenced to a harmonized road network. Traffic and travel event data can be automatically created from traffic flow data. TIC can create as well as distribute standard TPEG TEC (Traffic Event Compact) and TPEG TFP (Traffic Flow and Prediction), referenced either to TMC locations or the standard AGORA-C and Open LR referencing methods used to dynamically encode and decode locations without using a fixed TMC location table. The TPEG messages can be distributed as either binary, over THTTP, as digital radio broadcasts such as DAB and HD, or in tpegML to exchange TPEG data with other service providers or systems.

Worked examples

Example 1 — a first encounter with GEWI

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

In research: GEWI appears in 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 GEWI 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: GEWI is common in secondary-school and first-year university syllabi. It links to neighbouring topics Automotive navigation systems, Bernburg, German companies established in 1992, so understanding it makes those chapters shorter.
In everyday life: Look for GEWI 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.

Why does GEWI matter?

Because it connects several 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 GEWI?

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.
