Abstract

A method for ascertaining consumption and/or emission values of at least one vehicle in a traffic area, includes the following steps: determining a number of traffic-technology variables for the traffic area, ascertaining a driving profile of the vehicle based on the traffic-technology variables, assigning an individual consumption and/or emission model and/or a consumption and/or emission model related to the vehicle type group to the driving profile of the vehicle, calculating consumption and/or emission values based on the driving profile and the consumption and/or emission model. In addition, the invention relates to a corresponding method for ascertaining consumption and/or emission values of the vehicle target group of vehicles present in a traffic area and to a method for traffic control employing the consumption and/or emission values. Furthermore, the invention relates to ascertainment systems for ascertaining consumption and/or emission values and to a traffic control system.

Claims

1-14. -14. (canceled)

15. A method for ascertaining consumption values and/or emission values of a vehicle target group of vehicles located in a given traffic area as a function of a traffic control state, the method which comprises the following steps:

ascertaining driving profiles of the respective vehicles in the traffic area and/or subgroups of the respective vehicle target group;

assigning consumption models and/or emission models to the driving profiles;

calculating the consumption values and/or emission values of the individual vehicles and/or of the subgroups;

cumulating the consumption values and/or emission values of all the individual vehicles and/or of all the subgroups of the vehicle target group.

16. The method according to claim 15, which further comprises:

determining a plurality of traffic-technology variables for the given traffic area; and

ascertaining the driving profiles of the respective vehicles and/or the subgroups of the vehicle target group on a basis of the traffic-technology variables.

17. The method according to claim 15, which further comprises:

allocating individual vehicles and/or subgroups of a vehicle target group to a vehicle type group; and

assigning a vehicle type group-related consumption model and/or emission model to the driving profiles of the vehicles of the vehicle type group.

18. The method according to claim 17, wherein the allocating step comprises acquiring measurement data in the traffic area and allocating the individual vehicles and/or the subgroups of the vehicle target group to the vehicle type group by way of pattern recognition based on the measurement data acquired in the traffic area.

19. The method according to claim 17, which comprises ascertaining a number of vehicles of a vehicle type group within the vehicle target group by using an estimate.

20. The method according to claim 15, which comprises using consumption models and/or emission models based on vehicle type-related data.

21. The method according to claim 15, which comprises identifying individual vehicle types of the vehicle target group by way of pattern recognition.

22. The method according to claim 15, which comprises ascertaining the consumption values and/or emission values for different traffic control states in a defined traffic scenario, and ascertaining consumption comparison values and/or emission comparison values of the different traffic control states in the traffic scenario on the basis of the consumption values and/or emission values.

23. The method according to claim 15, wherein the driving profiles are simulated and/or a traffic control state comprises a model.

24. The method according to claim 15, which comprises ascertaining driving profiles using a vehicle locating system.

25. The method according to claim 15, which comprises ascertaining the driving profiles using a plurality of measurement systems mounted in the traffic area.

26. A traffic control method, which comprises:

performing the method according to claim 15 to acquire traffic-technology parameters in the form of consumption values and/or emission values; and

generating control rules on the basis of the traffic-technology parameters; and

generating control commands for operating traffic systems based on the control rules.

27. A system for ascertaining consumption values and/or emission values of a vehicle target group of vehicles located in a given traffic area in dependence on a traffic control state, the system comprising:

a driving-profile-ascertaining unit for ascertaining driving profiles of individual vehicles and/or subgroups of the vehicle target group;

an input interface for receiving data of consumption models and/or emission models;

an assigning unit for assigning consumption models and/or emission models to driving profiles;

a computer unit for calculating consumption values and/or emission values; and

a cumulating unit for cumulating the consumption values and/or emission values of individual vehicles and/or subgroups of the vehicle target group.

28. A traffic control system for controlling traffic systems, comprising:

an input interface for traffic-technology parameters;

an ascertaining system according to claim 27;

a rule-generating unit connected to said ascertaining system, said rule-generating unit generating control rules using consumption values and/or emission values generated by said ascertaining system; and

a control-command-generating unit connected to said rule-generating unit for generating control commands for operating traffic systems on a basis of the control rules.
