Definitions

  • the invention relates to a method for traffic-technical definition of a node at which traffic flows are controlled by a light signal system comprising signal groups, as well as a device for carrying out this method.
  • a traffic signal system consists of a combination of light signal transmitters, which transmit switching signals of signal programs running in a control unit to light signals, in particular alternating light signals, to the road users.
  • light signals which always indicate identical states, are combined to form signal groups.
  • a control unit is operated in fixed-time control or via a traffic-dependent control, in which the signal program within a master plan can be influenced by the road user.
  • the traffic conditions are automatically detected at the nodes of detectors and transmitted via a data transmission system to a central for the control area of the traffic route network traffic computer.
  • the transmitted traffic data are analyzed and, using an optimization and decision model, the control variables of the traffic signals, such as circulation times, release times, replacement times, phase sequences and the like, are recalculated.
  • Signal programs are generated from the new control variables and transmitted to the ECUs as process data.
  • a light signal-controlled node of a traffic route network is from a control point of view through its topology, ie the mutual geographical position of the adjoining node node arms and the geometry of the conflict area, by its traffic objects, such as lanes with direction distributions for access roads and exits of the junction arms, fords for cyclists and pedestrians, signal groups and detectors, and by traffic parameters, such as maximum speeds, minimum times, reference times and erection lengths described.
  • traffic objects such as lanes with direction distributions for access roads and exits of the junction arms, fords for cyclists and pedestrians, signal groups and detectors, and by traffic parameters, such as maximum speeds, minimum times, reference times and erection lengths described.
  • traffic parameters such as maximum speeds, minimum times, reference times and erection lengths described.
  • SITRAFFIC C800V / VK / VP / VX Edition 003, order no. A24705-X-A331 - * - 04, pages 1-26 and 1-27, published by Siemens AG, well-known supply program SITRAFFIC Control a comfortable interface.
  • the user is provided with a window-oriented, graphical user interface, by means of which the user is provided with intuitive operation with the mouse, the selection of functions according to Windows conventions via buttons.
  • the supply program the supply data of the control unit can be created, changed and loaded.
  • the main window provides the components project management, supply and documentation as well as components for general program functions.
  • the core of this well-known supply program is the project management component, from which the objects for the basic supply, user programs, simulation and signal protection subsections can be reached.
  • the available versions of each subarea are assembled into a node project, whereby a plausibility check prevents the combination of incompatible versions.
  • All traffic objects of the project are displayed in a tree structure. Using the object tree, individual objects can be specifically called up for editing via property editors. Corresponding icons in the tree inform about the state of the processing. So-called "special editors", such as graphic editors in the signal plan, the phase transitions, the public transport memory etc. support the user in the input of data.
  • Component supply includes transferring the data to the controller itself or backing up the data to the flash memory.
  • a special position is occupied by the Documentation component, which is used to control a separate program for the administration and printing of all information about a project.
  • This part of SITRAFFIC Control is especially geared to the requirements of a planning or engineering department for a complete and comprehensible compilation of all relevant project data.
  • SITRAFFIC P2 Planning and Design System for Light Signal-Controlled Nodes and Nets, Edition 06/00, order no. A24705-X-A323 - * - 04, published by Siemens AG, discloses a tool for processing light signal controlled nodes and coordinated networks.
  • SITRAFFIC P2 offers the traffic engineer assistance in planning and configuring signalised nodes with the functions such as: Intermediate time calculation with automatic route determination from the site plan, signal plan calculation and graphic processing, but also in the creation of basic data and parameters for various traffic-dependent control methods with the functions such. Phase processing and frame plan generation. In the site plan, all topographic elements can be created and reference lines and conflict points generated.
  • the background image can be loaded with a bitmap or a vector graphic on which the scaled processing takes place.

  • AMPEL 4 Planning, optimization and data management for traffic signal systems
  • It is used for the calculation and optimization of signal time schedules, in particular of split times, waiting times and tailback periods. It also offers planning steps for fixed-time control at the single node and for traffic-dependent controls. Green times can be graphically moved, lengthened or shortened in the signal time schedule on the screen with the mouse.
  • the processed signal groups are displayed graphically on the screen.
  • the traffic-technical definition of a light signal-controlled node takes place in the known method via separate entry tables whose entries are related to one another either via selection lists, so-called combo boxes, or via other referencing tables. Such a procedure is cumbersome and time-consuming, and it is also prone to referencing errors.
  • the display of the traffic-technical objects of a node in a tree structure is not very clear, while a graphical processing on a site map as a background can not generate a mutual assignment of the applied traffic-technical objects.
  • the invention is therefore an object of the invention to provide a method according to the preamble of claim 1 and an apparatus for performing the method according to the preamble of claim 8, which allow a comfortable and fast traffic definition of a light signal controlled node, where it is particularly vivid for the user and be prone to input errors.
  • the object is achieved by an initially mentioned method or an aforementioned device with the characterizing features of claim 1 or 8.
  • By graphically representable Zufahrtsschemata are provided for node arms, which have combinations of associated traffic-technical objects for a Knotenddlingarm, can scheduling traffic engineer the objects defining the node are displayed clearly displayed on a screen, the references or assignments of the combinable objects of a node arm are stored programmatically.
  • the planning traffic engineer can successively and quickly use the tools available to him via selection menus at Make a junction subsequent road sections.
  • the processor Since in this case the respective current processing status is displayed on the image display means by a stylized image of the node with the selected traffic-technical objects, the processor is offered a particularly clear and vivid process.
  • a stylized standard image of a node with, for example, four arms by clicking on a particular Knotenarmarmes with a computer mouse on a screen, the desire to edit the same can be signaled, according to the invention, the user is offered the selection of the access schemas.
  • its topology can be developed by removing it, by providing it with other traffic objects and by changing node nodes at any time.
  • the access schemes may have separate lanes for public transport vehicles or rail vehicles. Due to the overall limited choices for lanes and fords and the combinable number of one, two or three signal groups and the possible directional distributions, it is easy to produce the references between the selected traffic-technical objects. In practice, this is done directly in the selection of the desired combination, for example by clicking with a computer mouse in the approach scheme for the node arm.
  • the processing status of the developed topology on the image display means is additionally tabulated Form displayed.
  • the traffic-technical objects selected for the individual node arms which are described in the stylized image by symbols or short names, can be listed accordingly and supplemented by further traffic-technical parameters. This improves the clarity and offers an additional possibility to enter changes via the image processing means.
  • the directions of lanes and the associated signal groups on the stylized image are matched in color. This visually emphasizes the relationship between lanes for different directions of a node arm and the traffic streams in the respective directions controlling signal groups.
  • the associated line can be stored in a table with the same color. If, for example, a certain lane is marked on the stylized image, it lights up together with the assigned signal group and the corresponding table entries in a coordinated color.
  • nodes can also be defined by traffic engineering with the method according to the invention, which are to be controlled traffic-dependent by the traffic signal system.
  • selected lanes of the node arms which in reality are not associated with any physical detectors, are assigned virtual detectors for which replacement values can be entered.

  • flat rate or time and tag type related substitute values resulting from traffic measurements or estimates come from be entered.
  • the values can be preset in the tables, with the possibility of being changed by the traffic engineer working on them.
  • geometric dimensions of the node or its traffic-technical objects are input and derived therefrom traffic parameters of the node automatically.
  • the extent of the conflict area of the node can be queried. For example, at a node having four pairs of opposing node arms, the distances of opposing stop lines determine the dimensions of the conflict surface.
  • Intermediate times are calculated automatically for the node. This is the time between the end of the release time and the start of the release time for two traffic streams using the same conflict area consecutively.
  • the intermediate time results as the most unfavorable value of all combinations of lanes of a signal group to possible exits.
  • the distance of a detector to the stop line can be entered.
  • the distance of the node to the nearest nodes can also be entered to allow calculation of the offset times. This is the time difference by which the release times of the signals at the individual nodes are matched to one another to produce a coordinated control.
  • the stylized image according to FIG. 1 shows a processing status of the topology of a light signal controlled node 1, as it can be displayed on the image display means according to the inventive method for traffic engineering defining the node 1.

Furthermore, for the approaching over the Knoten Vietnamese traffic flows, which are on the lane 7 for left turn or lane 8 for straight-ahead and right turn move, a signal group SG7 or SG8 applied. For the Knoten Vietnamesearm 5 on the ford 13 crossing pedestrian flows the signal group SG13 is created. For the optically simpler assignment of the selected objects on the image display means, related objects are color matched. In FIG.
