Definitions

  • the invention relates to a traffic control system according to the preamble of Claim 1.
  • Vehicle computer also board computer or on-board units, hereinafter referred to as OBU
  • OBU are used for automatic execution various actions in public transport vehicles, For example, position determination, stop announcement or display of the Stop name.
  • the OBUs need application software and Reference data.
  • the application software specifies the type of actions while the reference data provided routes and points for the Trigger actions include.
  • a malfunction for example an accident or a gas pipe break on a scheduled route
  • the vehicles must be on a Drive the detour route.
  • vehicles are both Road vehicles, for example buses, as well as railbound Vehicles, for example trams, to a vehicle fleet understand.
  • the correct functioning of the route actions on everyone The route, including the detour routes, is an important one Quality feature of local public transport represents Acceptance and frequency of use of public transport the passenger depends very much on this quality feature.
  • There is an increased number of routes especially when changing routes Passenger's need for information both at the bus stop and while using the means of transport. That’s why proposed to use diversion routes for quasi-predefined incidents Have spare data blocks ready.
  • the corresponding data blocks are in the database of the control center and in the OBU of the vehicle and are transmitted to the vehicle from the control center via radio data transmission transmitted route number activated.
  • the disadvantage of this method is that only a limited number of detour routes is possible.
  • the bypass options are practical, for example in the case of a Accident barriers, especially for vehicles that are not bound to a rail almost unlimited.
  • the object is characterized by the characteristic features of claim 1 solved.
  • On-line radio data transmission is provided the rerouting route from the central computer to the OBU.
  • the computer determines an optimal one as required Detour route, the reference data forming the position specifications, including any stops, and the associated route actions as summarized at least one data block and via radio data to the OBU of the vehicle are sent.
  • the data block for the Change route virtually overwrites the corresponding data block for the scheduled route.
  • the overwriting is preferably carried out according to claim 2 by means of P198 42 779.4 known method for the selective loading of data and Software into an OBU.
  • the download server first provides the current state of charge of the OBU and determines the required one Modification. This analysis is carried out in data blocks, whereby advantageously only the at least one to be replaced or Data block to be added needs to be transmitted to the OBU.
  • the new data block is created manually.
  • the download server is equipped with resources, for example in Form of a keyboard, provided by a dispatcher to the default of the data blocks are used.
  • Claim 4 characterizes such a variant on the Basis for navigation means known per se. As soon as the calculator one If any fault information is received, one of the existing streets is used or digital route map in the vicinity containing railways the fault location was evaluated for detour options. Based a decision criterion, for example the length of the Detour route becomes the most optimal route for the detour, for example, the shortest detour route, determined and as a data block generated with reference data and route actions and via radio data transmission the OBU forwarded. The OBU takes over the data block instead of the now invalid data blocks and controls the corresponding systems of the vehicle. This also includes driver information for example as a visual representation of the detour route and the original route can be formed on a display.
  • a traffic control system shown in the diagram essentially consists of a control center 1 with a connected computer 2 and vehicles 3 to be monitored.
  • the control center 1 is in bilateral communication communication with the vehicle 3 via data radio 4.
  • the vehicle 3 is with an on-board unit 5 equipped, which stores reference data and software.
  • the reference data characterize striking points of the route R1, in particular those points at which route actions, such as traffic light activation, stop signaling, announcements and displays in vehicle 3 or activation of a ticket validation system, are triggered.
  • the type of route actions is specified by the software stored in OBU 5.
  • the OBU 5 recognizes via a position determination system, in particular satellite-based, whether a route action is to be initiated. In this way, the driver is relieved and the passenger, for example, is very comfortably informed about the next stop.
  • OBU 5 As long as the route R1 programmed in OBU 5 is followed, these tools are available for automatically triggering route actions. However, if a fault occurs, for example a gas pipe break or an accident is blocked, on route R1 and it is necessary to bypass the fault location on a detour route R1 ', OBU 5 must either be deactivated or with the data for route specification and route-specific control of the route actions of the detour route R 1 'can be programmed or reloaded.
  • the computer 2 in which a download server 6 is integrated, is provided. The download server 6 configures data blocks in an OBU-compliant form.
  • the new data blocks can be received and processed by the OBU 5 via the radio data link 4, for example by overwriting the data between stops A and B with the redirection data between stops A-C-D-B.
  • the rerouting route R 1 ' is determined with the aid of a dispatcher who evaluates a route map - road or rail routes - via a computer system 7 with keyboard 8 and display 9.
  • the dispatcher marks the intended detour route R 1 '.
  • the selected detour route R1 ' is confirmed with a click of the mouse 10 and, with all the associated data for route actions, is quasi assembled from a memory for a large number of existing routes and transmitted to the download server 6.
  • the OBU 5 replaces the data of the regular route R 1 between the stops A and B by the transmitted data of the diversion route R 1 ' from stop A via stops C and D to stop B. This means that the OBU is also functional on the detour route R 1 '.
  • the computer 2 can also automatically determine the selection of a suitable detour route R 1 '.
  • the computer 2 uses the digitally stored route map to search for a suitable diversion route R 1 'in the manner of a navigation system.
  • the length of a possible detour route R 1 ' can be used as a selection criterion in comparison to other detour routes which are in principle also possible.
  • the invention is not limited to the above Embodiment. Rather, a number of variants are conceivable which, even if the execution is fundamentally different, from the Make use of features of the invention.
