Definitions

  • the invention relates to a method for transmitting route data, a method for the analysis of a traffic route network, a traffic registration center and a Terminal.
  • the transmission of route data between a vehicle and a control center that is in particular the transmission of one each covered by a vehicle Path-related data (FCD) from the vehicle to the control center or e.g. the Transmission of further assignable in a control center to a transmitted route transmitted data, such as travel times of vehicles charged because of the very high Number of vehicles the transmission path very strong.
  • FCD vehicle Path-related data
  • a transmitted route transmitted data such as travel times of vehicles charged because of the very high Number of vehicles the transmission path very strong.
  • DE 195 08 486 A1 discloses a method for transmitting position data via mobile radio between a vehicle and a control center, each of which is based on a predetermined interval with a GPS receiver position data in the form of a point (specifying longitude and latitude), where two points are connected to a vector and from all so obtained Vectors a first vector train is formed.
  • the first vector is used for data reduction
  • Straight lines approximated with increasing number of straight lines until the maximum distance of the actual position data from the straight line below of a predetermined threshold value, whereupon those reduced in this way
  • Position data are transmitted.
  • An access to information in a digital Traffic network map is not recommended for data reduction.
  • the object of the present invention is therefore to optimize the transmission of route data between a vehicle and a control center.
  • the invention optimizes the transmission of route data by reducing the Redundancy, i.e. by increasing the information density during transmission. For this will each have one or more edges in the digital map of the Traffic route network, in which vehicles move, to partial routes summarized.
  • Route data can be identified with a description of the partial route which they relate to are transferred. Other dates such as travel times, Environmental data, temperatures etc. can e.g. by designating a partial route and of the location on the partial route.
  • the nodes of a traffic route network can lie on one, two or more edges. If there is only one edge on a node, it is an end point of the Traffic network. If there are two edges on a node, it can be a subdivision of a street, roadway, lane group etc. in the longitudinal direction in act several edges, two edges each by a node are connected. If there are three or more edges on a knot, it acts is a junction or intersection of roads, lanes, lane groups etc. An intersection with more than three edges can be divided by several Knots with three edges to be replaced.
  • the different directions of a street can be represented by one or more edges.
  • Route data in the sense of Claims include data that is covered by one vehicle at a time Identify the path, namely the edges or the partial paths, each one or include several contiguous edges and together the covered Make way. If the route of a vehicle in a digital map of a transport network in the head office can also Further data such as travel times can be assigned to this route.
  • Route data transmitted can in particular be one from a vehicle with one Traffic detector traveled route and from vehicle to headquarters be transmitted.
  • the data determined in this way in the central office can in particular for travel time statistics and for later recommendations on the choice of routes Vehicles are used.
  • the route data can also relate to the vehicle in particular Head office recommended route and from the head office to the vehicle respectively can be transmitted to several vehicles. It can be used for a vehicle or determined several routes based on travel time statistics in a central office Travel times are informed and advice on the selection of routes.
  • the transmission of a route is expediently carried out by the transmission of Designations of the partial routes forming it.
  • a way can be from one or exist several partial routes.
  • the names of the partial routes can be found in the Central and in the vehicle in identical or different databases stored with an assignment of edges forming a partial path one partial route each; instead can also be used in the head office and in the vehicle at least one set of rules for the formation of partial paths from edges be stored and for the identification of partial routes of a route to be transmitted these rules are used.
  • edges when assigning one or more edges each Partly because of the road types of these edges are taken into account; thus can for example partial routes from edges representing highway sections or from Edges representing highway sections and country roads are formed.
  • the associated period or time is preferably transmitted for route data.
  • the exact time or a quantified period of time are transmitted and stored in the headquarters.
  • the control center can also transmit route data, what time period, for example what time of day, what day of the week or which day of the year these route data relate to, for example Precise route recommendations for traffic jams occurring at certain times of the year can be transmitted.
  • the target file from a source file is used to reference partial routes in the Suitable transmission of route data between a control center and a vehicle Target file created.
  • Different can be used to generate the target file Approaches can be chosen. For example, starting from a as Starting nodes selected nodes of the network, partial routes are defined in such a way that with ascending numbering of the partial routes, one partial route through if possible long left turn, starting from the starting node. This regulation is very easy to implement.
  • FIG. 1 shows a digital road map of an edge 1 to 17 and node A to T extensive traffic network.
  • An edge here comprises a section of the route a street.
  • the edge 1 is between the two nodes A and B
  • the edge 2 is between nodes B and C
  • edge 3 is between the Nodes C and D etc.
  • the nodes are A, G, J, P, T each start node of the digital map of the traffic network, so Knots, of which only one edge or only one edge of the considered Street classes.
  • the nodes B, D, L are branch nodes, i.e. nodes with at least three adjacent edges; this means, for example, from the edge 1 At node B, drive a vehicle in the direction of edge 2 or edge 10 can that there is a real possibility of branching off.
  • a junction node can also have more than three edges, for example at an intersection; however, it is also possible to get the here selected representation with branch nodes with exactly three edges each preserved, even at intersections with more than three edges, several junction nodes to define from which exactly three edges each originate.
  • the nodes C, E, F, H, l, K M, N, Q R are nodes, of which only two edges, for example Edge 2 and 3 start from node C.
  • edges can be in one Digital road map representing traffic route network for specific purposes, such as. Congestion detection may be important, however they are used to analyze a route and transmission of route data relating to this route, in particular Travel times, not important.
  • a traffic route network can be used representing digital map, i.e. output file, to form a partial route of the Traffic network with target file representing low redundancy Consideration of edges and / or nodes of only a certain road class, for example, freeway, are taken into account; also e.g. from one Output file several target files for each street class can be formed.
  • a traffic network representing digital road map in Figure 1 a way and this way further route data in question should be transmitted by The passed nodes and / or the passed edges are transmitted.
  • the passed nodes and / or the passed edges are transmitted.
  • This way can be in a terminal in the vehicle due to a position detection system (e.g. GPS) and / or one Odometer and / or a speedometer and / or the detection of the Steering movements of the vehicle and / or a digital road map etc. detected become.
  • a total time required for this route can be added to the route and for partial routes of the route, partial route times are recorded.
  • This route data should be transmitted from the vehicle 18 to a control center. This can be done from a terminal in the vehicle 18 to the central office, for example by radio, in particular mobile radio, respectively.
  • radio in particular mobile radio, respectively.
  • transmission according to GSM in particular GSM SMS, can be selected in the form of a short message.
  • a vehicle 18 can travel From A to J the edges 1, 2, 3, 7, 8, 9 and the time required for this as Route data can be transmitted to a control center. Because of the variety of However, vehicles have a very large amount of data. The capacity of the However, the available transmission medium is limited. Therefore the resulting data volume can be kept as low as possible.
  • the traffic route network is broken down into partial routes.
  • One or several edges 1 - 17 form a partial path.
  • at least one set of regulations for the formation of partial routes in one Traffic network or one according to a set of regulations from the digital Road map of a traffic route network (output file) less formed redundant (information technology compressed) digital road map of the Traffic route network (i.e. destination file) must be saved.
  • the regulations for dividing the transport network into partial routes can be chosen in this way be independent of the digital road maps that exist in the terminal and the head office can be used.

  • a further set of regulations for the formation of partial routes in a digital road map representing a traffic route network can be as follows: A partial route is formed starting from any exit node A with increasing node numbering, by turning left for as long as possible until a further exit node G, J, P, T. Paths between this output node A and the other output nodes are thus detected. After all possible routes from the output node A have been processed, a further rule can lie in the choice of a further output node G, all of which except the route to the output node A already considered being defined accordingly as partial routes. Another requirement may be to proceed accordingly with the remaining exit nodes.
  • a route as transmitted route data would only contain a partial route.
  • Another set of regulations for the formation of partial routes can also be defined as follows: From an arbitrarily selected output node A turns left as long as possible to another exit node G, J, P, T analyzed; partial routes are only used for routes between exit nodes and Output node and possibly additionally between output node and Intersection node defined if based on recorded traffic data from Vehicles shows that a relevant number of vehicles are traveling this route.
