Here we give you an alphabetically sorted overview of the most important technical terms from the world of navigation and of course from the MapTrip world. Our glossary is constantly being expanded and is also available in German.

Connected traffic

Connected Traffic is the traffic service in MapTrip. Due to the amount of traffic information used, the traffic situation on the MapTrip servers is taken into account and the route is checked regularly. The MapTrip application must be connected to the server.


Reaching the destination terminates the MapTrip destination guidance. The destination is at the end of a tour.

Destination guidance

The destination guidance is the support of the navigation software for the driver when driving along the route by displaying the map and announcing turn-by-turn directions. The destination guidance starts after entering the destination either by interaction of the driver with the GUI or by command via one of the MapTrip interfaces. The destination guidance ends when the destination is reached.


ETA stands for Estimated Time of Arrival. When Connected Traffic is used, the ETA is regularly calculated by the MapTrip server, taking into account the current traffic situation and based on statistical traffic information. It is therefore very precise. Without Connected Traffic, the ETA is estimated by the MapTrip app itself based on the types of roads travelled.

Floating car data (FCD)

Floating car data (FCD), also known as floating cellular data, is a method to determine the traffic speed on the road network. It is based on the collection of localization data, speed, direction of travel and time information from mobile phones in vehicles that are being driven. These data are the essential source for traffic information and for most intelligent transportation systems (ITS). This means that every vehicle with an active mobile phone acts as a sensor for the road network. Based on these data, traffic congestion can be identified, travel times can be calculated, and traffic reports can be rapidly generated. In contrast to traffic cameras, number plate recognition systems, and induction loops embedded in the roadway, no additional hardware on the road network is necessary.


Floating Car Data is the raw material for traffic information. Flow data and statistical data are obtained from them.

Forecast data

Forecast data are used to predict how traffic will change. Ideally, in instances of two parallel freeways, for example, it should provide the decisive information on whether the driver will subsequently end up in a jam or not.

Intermediate destination

A tour can contain one or more intermediate destinations. In contrast to the destination, the next destination guidance is directly planned after reaching an intermediate destination.

MapTrip-Interface (MTI)

The MapTrip Interface (MTI) is an interface for communication between MapTrip and other applications. MTI can be used, for example, to start a destination guidance to an address or to query the ETA calculated by MapTrip for the current destination.

MapTrip MapAPI

The MapTrip MapAPI is a library of functions for interacting with MapTrip. It makes it possible to assign a destination to a MapTrip navigation and to start the navigation in a very simple way. The MapTrip MapAPI is based on the MapTrip servers, which also realize the communication with MapTrip.

MapTrip Server

MapTrip Server is the name given to all servers operated by infoware for MapTrip. In detail, these are servers for calculating routes, for processing the traffic situation or for providing constantly updated map material.


See tour.

Providers of Traffic data

infoware works with the three main providers of traffic information. TomTom, Here, and Inrix deliver high-quality traffic information. MapTrip does not use TMC and TMCpro due to the lack of coverage of the entire road network.

Reference route

A reference route is a route that is not the result of a route calculation, but whose course was defined by a detailed default. Use cases for reference routes can be, for example, that routes calculated by third party systems are to be run in MapTrip. Compared to the via point, a reference route is based on hundreds or thousands of points.


A route is a connection between two points on the map that leads across roads so that it can be driven by a car or truck.


Routing is the method or process of route calculation. With MapTrip we differentiate between routing for cars, trucks or emergency routing in MapTrip 112, for example. When using a reference route or a FollowMe route, however, no routing takes place in MapTrip because the route has been specified externally.


The SDK are the libraries on which the MapTrip application is based. The SDK is created by the core team and delivered to customers as a standalone product.

Statistical traffic data

Statistical traffic data represent the speed of traffic that can typically be expected on a section of road. This is available for every day of the week in 15-minute intervals and is obtained from a statistical analysis of the flow data from traffic data providers. Statistical traffic data is important to calculate realistic routes with exact driving times even in places with no available current flow data.


“Traffic message channels (TMCs) are used to digitally send information about traffic disruptions in the inaudible range of the FM signal. Navigation systems can receive congestion information via TMC and thus generate routes to circumvent the jams and obstacles (dynamic route guidance). Due to system limitations, TMC can only roughly delineate the areas of traffic jams as the only points of reference are freeway and main road intersections. If the traffic jam is between intersections, it is possible to ascertain its length, but not the exact area.”



“Navteq (now Here) Traffic, originally called TMCpro, is a paid TMC traffic jam warning service that is distributed via the RDS sub-carrier of FM stations. Unlike freeTMC, Navteq Traffic is only broadcast over private radio transmitters and not over public service broadcasters, as it is a paid TMC. The service was launched in April 2004 by T-Systems under the name TMCpro.”


TMCpro is an advanced version of TMC. In addition to the editorial content, this service also broadcasts information from, e.g., sensors on bridges.


A tour consists of several routes which are run immediately one after the other. Each route ends at an intermediate destination where the announcement “Destination reached! The destination guidance to the next waypoint can be started automatically or after interaction with the user.

Traffic events

Traffic events are traffic notifications similar to those broadcast on the radio. They describe a traffic event at a specific location or on a road section. In the old days (TMC and TMCpro), traffic events were the only information that was transmitted to the navigation systems. This resulted in a black-and-white perspective, which implied that if there wasn’t a TMC message (= traffic events), the traffic must be flowing freely. This led to many annoying situations, in which traffic would be guided to a congested roadway in order to get around a jam. This is why MapTrip calculates routes primarily based on flow and statistical data. Traffic events are shown on the map for information purposes.

Traffic flow data

Traffic flow data provide the actually measured speed at which traffic is moving on a given stretch of road. Initially, the flow data does not offer information on whether traffic is backed up or not. 18 mph can be a completely normal speed on a city road, but probably indicates a jam on a freeway. This must be interpreted before the flow data can be displayed on a map in the typical green/yellow/red fashion. With MapTrip, this data is used not only for display, but also to calculate the route.

Via point

A via point influences the course of a route. A route can contain numerous via points. Via points are used to influence the course of a route according to your own requirements. The route then runs from the start via the via points to the destination. Passing the via points is unnoticeable for the driver.
