Definitions
- the invention relates to a method for transmitting location data and measurement data from a terminal, in particular a telematics terminal, to a traffic control center.
- FCD traffic data
- FCD floating car data
- data that implies the location of the vehicle at several successive times may be transmitted from a vehicle (FC) to a traffic center, including data that implies one time each, as well as measurement data acquired by the vehicle, such as speeds, cruising speeds, temperatures and the like, at certain times certain places or between certain places where the terminal was at the time.
- the object of the present invention is a simple, inexpensive and efficient reduction in the telecommunication costs for the transmission of data from a terminal to a traffic control center.
- the object is solved by the subject matter of the independent claims.
- the invention leads to a reduction in the telecommunications costs incurred.
- the terminal transmits the location of the terminal in a traffic network at each point of time implicit location data and properties of the traffic network at one point and / or measurement data implicit at one point of time independently. Location data on the one hand and on the other hand
- Measurement data prior to transmission are combined into location data records and measurement data records that contain one measurement date or location date or several measurement data or location data at different locations or times.
- Properties of the traffic network implied by measurement data at one location and / or point in time can in particular be data that indicate a traffic jam and / or
- the location can be specified by a specific point-like location or by a location area (for example, a partial route of the transport network) specified by several points.
- the time e.g. properties of the traffic network implied by measurement data can be specified by a point in time or by a time range in the form of several points in time.
- Data records with measurement data can contain a reference date of a predetermined type for assigning the measurement data in the control center to a position in, for example, a digital map of the traffic network in the traffic control center; Such referencing can relate to the location of the traffic network and / or the point in time to which the measurement data relate on the basis of their measurement.
- a terminal according to the invention can be, in particular, a telematics terminal for a vehicle, which can be designed to acquire traffic data and / or to receive traffic data from a traffic control center.
- the method according to the invention enables optimal utilization of cost-intensive and possibly also only limited available telecommunication times during the transmission from one terminal to one
- Traffic control center Due to the independent compression or transmission of data records with only location data and data records with measurement data, the total amount of data to be transmitted is reduced. In addition, adaptation to local requirements is possible: For example, on a straight motorway route without branches or access roads, the transmission of location data is only possible in relatively large amounts Time intervals or local distances make sense, so that possibly more measurement data (on speeds, traffic jams, black ice, etc.) is transmitted than location data.
- a transmission of location data at short time intervals and / or local distances may be expedient, since a vehicle has a relatively large number of turning options, which require a relatively frequent location data transmission in order to completely record the path of the vehicle in the city, so that more location data than measurement data may have to be transmitted here.
- individual data records can contain location data and measurement data at times at which location data and measurement data arise for transmission.
- the length of a data record with only location data and / or a data record with measurement data is expediently variable.
- the location or time reference of data records to location data and of data records to measurement data can be different. Referencing can in particular include a location or time or a location area or time area. The transfer takes place conveniently via
- the transmission of the data records from the terminal to the traffic center as a short message is particularly advantageous, which allows a high degree of universality and automatic further processing in the traffic center.
- a transfer of measurement data records from the terminal to the traffic center can take place when an event of a type specified in the terminal occurs.
- Such an event can, in particular, mean that a vehicle in which the terminal is located falls below a speed value by falling below or exceeding one of several speed values, by driving through a tight curve (with a strong steering wheel lock and / or changing the direction of travel that can be detected by GPS) Vehicle in which the terminal is located), by the expiry of a time interval (after which a transmission of measurement data must take place) or the like in order to enable automation.
- a location data record can be transmitted after a specific time interval and / or when another event has occurred.
- Location data can also be transmitted, for example, when a vehicle is in which a terminal is located, a predeterminable location (from a large number of predeterminable locations), for example, a certain motorway junction.
- a specific location can be passed on the basis of a digital map in the terminal and / or on the basis of the position of the terminal detected by GPS or the like.
- the method according to the invention can be implemented in a terminal and / or a traffic control center.
- Fig. 1 as a single figure schematically a vehicle moving in a traffic network with a terminal, which data to a
- Fig. 1 shows a vehicle 1 with a terminal 2 according to the invention, the location data (GPS 13), the vehicle speed v measured by the vehicle 1 and the distance s traveled, the outside temperature T (on the vehicle 1) and the time t (by a digital clock etc in the terminal or vehicle).
- the vehicle 1 moves in a traffic network shown here in excerpts with, inter alia, an A8 motorway and federal roads B300, B17, passing through its vehicle locations x1 (t1), x2 (t2), x3 (t3), x4 (t4) in succession (t).
- x5 (t5) at times t1 to t5.
- the transmission 7, 8, 9 of Location data or 10 of measurement data from the terminal 2 to the control center 4 takes place by radio, here via mobile radio (antenna 18 of the terminal 2, antenna 5 of the traffic control center 4).
- a digital data format namely a mobile radio short message format (GSM-SMS) is used for transmission 7, 8, 9, 10.
- Data in the terminal 2 can be used for a data record with location data as well as for a data record with measurement data. This can be especially for
- Referencing of location data and / or referencing data used can reference the time and / or the location, which relate to location data and / or measurement data.
- a location can be specified as a location point or as a location area (x1, x2); a time can be represented as time t1 or time period t1, t5.
- the referencing of location data and measurement data serves to enable the assignment of location data x1 to x5 and measurement data v1 .. v5, T1 (t1) etc. in the traffic control center 4.
- data is assigned to one or both of two data containers.
- a data container is implicit for the location of the terminal at different times
- a second container is provided for other measurement data implied by the terminal device, in particular speeds, temperatures, travel times etc.
- Location data and / or measurement data may possibly be in the terminal 2 before the transmission (7 to
- data is separated into data records (or container 1) relating only to location data and data records relating to measurement data.
- data records or container 1 relating only to location data and data records relating to measurement data.
- Time data can possibly be assigned to both data records. Furthermore, further data such as the designation of the vehicle type etc. can also be transmitted during the transmission 7 to 10. Different criteria for initiating a transmission 7 to 10 can be defined for data records 11 to 13 relating only to location data and data records 14 relating to measurement data.
- a location of interest specified in the terminal can be, in particular, the start y1 of an A8 motorway or the location of a branch y4 of a B300 federal highway from an A8 motorway or the like.
- a terminal 2 is a
- Transmission causes when the direction of travel of the terminal 2 or the vehicle 1 changes;
- the change in the direction of travel can be due to continuous evaluations of GPS data 3 on the end device side and / or by a steering wheel lock of the extent specified at the expected speed on the A8 motorway, for which purpose a digital map in the end device 2 can possibly also be used for this purpose whether there is a curve here on the road A8 traveled by the terminal 2 of the time or / and whether there is a possibility of departure, motorway service area etc.
- the vehicle is not caused to indicate its location position for any other reason, it is also possible to arrange for transmission after certain time and / or location intervals.
- location data x1, x4, x5 which are transmitted from the vehicle 1 or terminal 2 to a center 4 for location determination, the path of the terminal 2 can be determined in the center 4 in a digital map 15.
- Plausibility checks inaccuracies or gaps in the determination of the location of the terminal 2 can be supplemented with the help of the map 5.
- the most probable path of a terminal 2 between two points x1, x5 known to the control center 4 can be determined on the basis of roads running between them.
- a data set with measurement data can be implemented in the terminal 2 different specifications alternatively or side by side.
- travel times can be transmitted if the actual travel time of the terminal t4-11 lies between two predetermined points y1, y4 above a predetermined value stored in the terminal 2.
- Transmission from the terminal to the control center can be triggered when the speed of terminal 2, possibly depending on the vehicle 1 type, is below or above one of possibly a number of threshold values specified in terminal 2.
- a transmission can also be triggered at a predetermined temperature, for example the freezing point or a temperature above the freezing point.
- control center 4 measurement data (speeds, travel times, temperatures, etc.) acquired by terminal 2 and transmitted as data record 14 is assigned to positions in digital map 15 in control center 4. If in a data record 14 with
- Measurement data for each measurement date that is recorded and transmitted by the terminal 2 (GPS 3) location x1 to x5, etc., can be directly assigned to positions in the map 15 in the control center 4. Furthermore, an assignment based on times transmitted to individual measurement data is possible, taking into account the route, ie locations x1, x4, x5 of the vehicle 1. This allows measurement data to be assigned to specific locations x1 to x5 on the route of the vehicle 1 on the digital map 15. If measured data in a measured data record 14 in the control center 4 for assignment or for checking the assignment to positions in the digital map 15 are compared with the path x1, x4, x5 traveled by a vehicle 1, it is expedient if 1 1 for each location data record , 12, 13 and also for measurement data records 14
- Vehicle identification is transmitted so as to enable an assignment of the measurement data sets to location data sets in the control center 4 for a special vehicle 1; the identification can consist, for example, of a mobile number (5) of the terminal or a virtual number.
- the starting point of the reconstruction problem is a discrete sequence
- Track or track profile support points have the attributes specified in the following table 1 .
- Table 1 Attributes of guideway and driving profile support points
- Table 1 Attributes of guideway and driving profile support points
- the two sequences PRH, SRH are indexed with respect to the time stamp attribute of their sequence elements PR j , SR j in chronologically descending order

- the individual driving profile sections characterize the driving profile using the mean throw 1 F. of the profile measured values ⁇ F (s)
- a reconstruction that is to say a solution to the reconstruction problem, is understood to mean a sequence of route elements of the predefined representation of the road network which best map the route described by the PRH and the driving profile described by the SRH to the road network.
- Track elements that are part of a reconstruction have values for the following attributes.
- the static attributes come from the network description (where question); the dynamic attributes are used to establish a time reference (when question) and to assign profile data (how question) for the route elements.
- the sequence R is sorted in time-descending order with respect to the attribute Time Stamp of its sequence elements SE k , ie it applies
- the time interpolation map T (s) represents a continuous interpolation with respect to all discrete time information from the PRH and SRH, ie every point e [ ⁇ , Max (L w , L p )] on the original route is an approximation T (s) for the Assigned time at which the point was passed by the floating car.
- T (s) depends on the model.
- the simplest time interpolation mapping interpolates between two successive time stamps t ,, t (+ 1 linear (constant

- + 1 , l 1 ... (N + M-1), t ⁇ s ⁇ + ⁇ ⁇ ⁇ ⁇ t ⁇ + 1 b l + 1 s l
- the Profilinterpolation F (s) represents a continuous interpolation with respect to the discrete motion profile data.
- F (s) depends on the model; the simplest profile interpolation mapping interpolates step-by-step, i.e. is defined in sections as follows:
- the projection relation P is a sequence of ordered pairs
- PR 0 ' SE c which assigns the elements PR _ PRH route elements SE from the set NB of the network display elements.
- PR e PRH PR e PRH
