Definitions

  • the invention relates to a method for assigning a driving line to a vehicle according to claim 1, a method for controlling a traffic system according to claim 10, a computing unit according to claim 14, and a traffic system according to claim 15.
  • the Dynamo system is designed for use in inner-city, regional and national public transport and is installed in vehicles that serve public transport.
  • the Dynamo system automatically and continuously records location coordinates of the vehicle with a navigation unit while driving and in a stationary vehicle.
  • a location recognition module compares these coordinates with internally stored reporting point coordinates and detects whether the vehicle is at a reporting point. If this is the case, then the vehicle has reached a position at which an action is to take place.
  • One action is, for example, the transmission of a defined data record to an LSA intersection computer.
  • the message data stored for each reporting point is used to identify which data the data record consists of and via which interface the reporting data is to be transmitted: via radio, serial or another interface. Thereafter, the generation of the data telegram takes place and then the transmission of the data.
  • a method for identifying a subset of positions is known. Thereby, the local travel history of a user of various public transportation can be determined. Based on this determined travel history then the travel costs to the individual operators of the means of transport can be fairly distributed.
  • the basis of the method is a comparison of the coordinates of public transport stops with the coordinates of base stations for transmitting and receiving operation in mobile communications. These coordinates must be determined only once and can be stored in a memory. If the coordinates of a base station, in which a cell phone is logged in, near the coordinates of this stop, it is assumed that the owner of the cell phone is at this stop.
  • the object of the invention is to provide an improved method for assigning a driving line to a vehicle and an improved method for controlling a traffic system.
  • the object of the invention is achieved by the method according to claim 1, by the method according to claim 10, by the arithmetic unit according to claim 14 and by the traffic system according to claim 15.
  • An advantage of the method described is that a simple assignment of at least one driving line to a vehicle takes place. Another advantage of the method described is that a simple way of achieving improved control of a traffic system is achieved.
  • a refinement of the method is achieved in that a further reporting point is taken into account in addition to the departure stop in order to assign a driving line to the vehicle. This allows a safe and fast selection of the driving lines can be achieved.
  • an additional reporting point and a travel time of the additional reporting point are detected and selected for the selection of the driving line to select the driving line. In this way, a further improvement for a quick assignment of a driving line to a vehicle is achieved.
  • the driving line is detected at the latest when the vehicle has left a predetermined departure stop at a predetermined starting time and the drive of the vehicle at a predetermined final stop ends. This can be done an assignment of the vehicle to a specified driving line.
  • a driving line can be defined by a fixed departure stop, a fixed start time and a final stop.
  • a circulation with at least two driving lines can be detected. For this purpose, it is checked whether the vehicle has traveled at least two lines at least a fixed number of times in the same sequence. Due to the automatic detection of a circulation of a vehicle's travel can be recorded and updated during operation without much effort.
  • the vehicle is assigned the current driving line and a preceding driving line. In this way, a temporal change between the driving lines can be checked and in particular a driving circuit with a plurality of defined successive driving lines are determined.
  • the vehicle is assigned a license plate for an unknown journey.
  • the vehicle is checked after detecting the deviation from the associated driving line on the basis of retarded reporting points, whether the vehicle returns to the previous driving line. If this is the case, then the vehicle is again assigned the previous driving line. If this is not the case, then the unknown drive remains assigned to the vehicle as the current driving line.
  • the assignment of the driving line to the vehicle is used to control a traffic system for the vehicle. In this way, a prioritization of the vehicle according to the associated driving line can be performed. This provides an improved traffic management system.
  • FIG. 1 shows a schematic representation of a computing unit 1, which is connected to a memory 2.
  • the arithmetic unit 1 has a transmitting and receiving unit 3.
  • a vehicle 4 is shown which has a second memory 5 and a second arithmetic unit 6.
  • the vehicle 4 has a second transmitting and receiving unit 7.
  • the vehicle 4 may also include a GPS system 8 for determining the location position.
  • the position of the vehicle can be detected by means of sensors or a camera, which are arranged for example at the traffic lights or at registration offices.
  • the traffic light 9 has in the illustrated embodiment, a third transceiver unit 10, a display 11 for displaying a released or locked direction of travel.
  • the display 11 may, for example, a driving direction in straight drive 12, a left turn 13 and a right turn 14 enable or disable.
  • the directions of travel are shown schematically in the form of arrows 12, 13, 14.
  • FIG. 2 shows a schematic representation of a table for a timetable of a first driving line F1 and a table for a timetable of a second driving line F2.
  • the first driving line F1 has a first departure stop S1, at which a vehicle is to depart at a first starting time ZS1.
  • further reporting points and arrival times for the reporting points are indicated.
  • the arrival time can determine the time of arrival at the reporting point or the time of departure from the reporting point.
  • a second reporting point P3 follows, which is to be approached at a second approach time Z3.
  • the first driving line F1 has an end stop E1, which should be approached at an end time ZE1.
  • the second driving line F2 has a second departure stop S2, which should be left at a starting time ZS2 from the vehicle.
  • the second driving line F2 has a fourth reporting point P4, which should be approached at a fourth approach time Z4.
  • the fourth reporting point P4 is followed by a fifth reporting point P5, which should be approached by the vehicle at a fifth approach time Z5.
  • the second driving line F2 has an end stop E2, which should be approached at a second end time ZE2.
  • a departure stop and an end stop also constitute a reporting point.
  • the reporting points of the driving lines are traversed from top to bottom in the appropriate order.
  • An assignment of a vehicle, in particular a vehicle in a public transport to a driving line can be dynamic during operation to change. This change can either be taken over by an operator of a vehicle fleet of an online interface or automatically determined via an internal algorithm.
  • a manual assignment of a driving line to a vehicle may be useful if a driving line can be statically assigned to a vehicle.
  • the driving line can be determined from a course of the journey of the vehicle.
  • the driving lines that is to say the driving direction, are dependent on the selected embodiment.
  • the routes for the individual routes are stored in advance.
  • a driving line contains at least two reporting points, which in the simplest case can be a departure stop and an end stop.
  • driving lanes contain more than two reporting points, since there are further reporting points or stops between the departure stop and the terminus.
  • the method for assigning a driving line to a vehicle in a computing unit in particular in a central processing unit can be performed.
  • the driving lines can also be determined automatically by a departure of reporting points by the vehicle.
  • departure times for the reporting points in particular for the departure stop can also be determined automatically.
  • different departure times can be recorded or provided.
  • different schedules may be provided for a driving line.
  • a message point sequence is understood to mean a plurality of message points that are traveled by a vehicle.
  • the reporting points may represent stops or other geographic points that are fixed.
  • a driving line contains a defined reporting point sequence, ie a defined number of consecutive reporting points which are traversed one after the other. If a vehicle changes between two lines, the stop in question must be marked between the two lines as both the last stop and the starting point.
  • a journey is understood to mean a movement of the vehicle from a departure stop to an end stop.
  • a ride is not necessarily tied to round trips.
  • a trip is marked by a driving line and its line number. This specifies a fixed number of reporting points for a trip.
  • a trip can be determined by a departure time at the departure stop.
  • an attempt is made at the beginning of a journey of a vehicle to determine the valid driving line for the drive of the vehicle. This happens, for example, on the basis of a comparison of the current departure time of the vehicle and planned departure times of different driving lines at the departure stop. If only one driving line is found during this check which matches the recorded departure time, then this driving line can be assigned to the vehicle immediately. However, if several lines are available for the same departure time, then another additional check is required to determine the actual driving line of the vehicle.
  • the departure time may be understood to mean a precise departure time or a period of time. For example, on buses, a departure time is usually not met precisely.
  • the drive through the vehicle is terminated, for example, by an identifier being set by the vehicle, in which the reaching of the final stop is determined. Begins a journey of a vehicle a departure stop at a time when no driving line is provided, then this journey is to store after reaching a final permitted stop and to mark as unavailable drive.
  • a vehicle can generally be occupied at exit from a depot with a predetermined line number, in particular with the line number 0.
  • a vehicle can be assigned the predetermined line number 0 if it is detected that the vehicle has left a previously assigned driving line.
  • a vehicle can be assigned the line number 0 if start at a departure stop several lines at approximately the same time and therefore the correct driving line can not be assigned.
  • a prioritization with respect to other road users can also be carried out for a vehicle with the line number 0.
  • a prioritization to other road users is made ,
  • a traffic light may have a priority signal for the vehicle, in particular for a bus or a rapid-transit railway, which approaches the traffic light and has the line number 0.
  • a defined route is stored as prioritized in the traffic light.
  • the parameter is assigned to each vehicle current line number, ie assigned the number of a driving line. It can also be the line number 0, which is used as a placeholder for an indefinite driving line.
  • the parameter current line number is used to prioritize the vehicle against other road users in the traffic system.
  • the parameter previous line number can be stored.
  • the parameter previous line number is derived, for example, from a current driving line with a current line number.
  • the previous line number can serve as a fallback if, for example due to a diversion, the current driving line, ie the current line number is set to the line number 0, but after passing the detour route, the current driving line is to be set up again.
  • the previous line number also serves as a helper when several lines with different line numbers are available at departure stops at the same departure time.
  • the previous line number can be kept as the current line number.
  • a parameter line number last drive can be stored.
  • the parameter line number last trip serves e.g. as an auxiliary size, if at departure stops at the same departure time several lines with different line numbers or better with different connection runs are possible.
  • This parameter is not like the current line number and the previous line number associated with a vehicle, in particular a computing unit of the vehicle, but a driving line, i. a ride.
  • the last-mentioned route number represents a time parameter and effectively links successive journeys of a vehicle to a circulation without having to additionally introduce this quantity.
  • the previous line number parameter is compared with the parameter line number last run.
  • possible line numbers for driving lines can be assigned to a vehicle if a precise selection of a driving line is not yet possible.
  • the line numbers including the associated parameters are temporarily stored from the candidate lines as possible line numbers for the in the period departing vehicles.
  • the selection of possible driving lines can be successively restricted by passing over reporting points, until a clearly one single driving line and its line number are left over.
  • the central processing unit 1 For a starting point of a journey, for example from a depot, the following points can be defined for a vehicle by the central processing unit 1: The current driving line is occupied by the line number 0, since the actual driving line is still unknown. The previous driving line is also occupied by the line number 0. The possible driving lines are also occupied by the line number 0. In addition, a flag for reaching the last stop is set.
  • a distinction in day types i. for example, Monday through Friday, Saturday or Sunday.
  • a plan for the driving lines available for a departure stop which are different, for example, according to the day.
  • a departure time is set for each driving line for the departure stop. Depending on the selected embodiment, the departure time can also be automatically detected for a vehicle and then stored as a predetermined departure time.
  • Each driving line is provided with a line number. The line numbers can be assigned automatically or manually.
  • a line number for the parameter last trip i. last driving line automatically generated and assigned to the vehicle.
  • a transition counter may be provided. The transition counter is automatically increased by the value 1 after the end of a driving line with a successful assignment of the parameter line number last drive at the last stop. Using the transition counter can be achieved, for example, that after a two-time carried out the same transition between two lines a fixed circulation with the two driving lines is determined. The circulation then includes these two driving lines. Depending on the chosen embodiment, a circulation may also include more than two driving lines. The known for a vehicle travel circulation can also be used to prioritize the ride of the vehicle over other road users.
  • At the departure station for example, at least one of the following actions is performed. If the "End stop reached" flag is not set, no action is taken. This is necessary if the departure stop serves only temporarily as a departure stop, for example at short-term. Otherwise, the processing of the following points is carried out: Reset the "End stop reached” flag.
  • the current line number of the vehicle is assigned the line number 0.
  • the current departure time of the vehicle is compared with the given departure times of the various possible driving lines. If an unambiguous assignment of the vehicle to a driving line via the measured departure time and the departure stop is possible, the line number of the unique driving line is assigned to the vehicle as a valid line number for the current driving line. If several driving lines come into question, the parameters of all possible driving lines are taken over into an area for possible line numbers.
  • a comparison of the previous line number with the line number last ride of the candidate lines is performed. If a driving line is determined in which the previous line number and the line number last ride are identical and the associated transition counter is greater than or equal to a predetermined number, in particular greater than or equal to 2, then the current line number of the vehicle with the recognized line number from the range of possible driving lines equated. In addition, the previous line number of the vehicle is set equal to the current line number.
  • the current line number of the driving line of the vehicle remains set to the value 0.
  • the previous line number parameter is retained from the last trajectory the vehicle has traveled.

  • a reporting point For a reporting point, several valid travel lines with corresponding line numbers are available, depending on the selected embodiment. If a reporting point is run over by a vehicle whose current line number for the driving line is equal to 0, then it is checked whether further possible driving lines are stored for this reporting point. If this is the case, it is checked whether one of the possible driving lines could be considered. If this is the case, then a restriction of the driving lines permitted at this reporting point is carried out. The remaining driving lines can be deleted depending on the selected embodiment. If only one driving line remains in this check, this driving line is immediately assigned to the vehicle as the current driving line. The previous trajectory parameter is stored under the parameter trajectory last traverse. Subsequently the previous driving line is set equal to the current driving line.
  • a subsequent method point it is checked whether the worn reporting point lies on the current driving line of the vehicle. If this is not the case, then the current driving line with the value 0, i. assigned with the line number 0. However, if the check reveals that the worn reporting point is on the driving line, the current driving line is set equal to the previous driving line and a prioritization in the traffic system is released. This means that in the further course of the vehicle is prioritized according to the assigned driving line compared to other road users with respect to a right of way. This procedure allows vehicles traveling on a detour route to be returned to the original driving line.
  • the "End stop reached" flag is set.
  • a storage of the current driving line with a time stamp and the indication of the last stop is checked whether the final stop lies on the assigned driving line. If this is not the case then the driving line for the last drive is set to unknown and the transition counter is set to the value 0.
  • the driving line for the last journey is checked. If the route is unknown for the last trip, an action will be taken. If the travel line is stored for the last trip, the transition counter is incremented by the value 1.

  • a driving line is formed from reporting point sequences that a vehicle departs with the corresponding journey times.
  • the departure stop for the first reporting point and the final stop for the last reporting point are defined.
  • the reporting points for departure stops and end stops are preferably defined so that they are easy to distinguish positionally. In the case of short-turn parking places, the direction of travel of the vehicle should additionally be clear at this point.

  • an analysis can be made as to whether the departure time for a departure stop is still used. If this is not the case repeatedly, this departure time can be deleted automatically or manually.
  • a parameter for the duration can be stored determining after which time of non-use of a departure time the departure time for the departure point is deleted. This can be for example a day, two days, three days or a week.
  • a cyclical analysis can be carried out to determine whether a new departure time has been added to a known driving line.

  • Exemplary Procedure On the first arrival after the system start at the departure stop, a comparison of the previous driving line with the driving line last journey is performed on the basis of several possible departure times. Since the parameter driving line last drive has not yet been determined, and thus is marked as invalid, the driving line is provisionally set for case 1 of the vehicle, as explained above. At the next arrival of the vehicle, for example, the next day at the same time and the same previous driving line, the comparison after Case 2 is most likely to succeed. Since, however, the transition counter only has the value 1, the second pass again uses case 1. Only if the passage has been successful twice or more in succession, a fixed circulation plan is recognized.

  • the vehicle is normally assigned a line number 0 for an unknown driving line. Vehicles are thus preferred, for example, only at the thus parameterized intersections. If a valid driving line is erroneously assigned, it will be reset to an unknown driving line and thus to the line number 0 due to the unplanned course of the journey in the vehicle. Although the course of a special trip is evaluated as a possible route, but since the departure station is not normally marked as such, there is no inclusion of the driving line as a new driving line.
