Checking the network
You can check the consistency of your network model with this functionality.
Note: The sections PrT and PuT are only available if you have activated the respective add-on (Enabling or disabling add-ons). |
1. On the Calculate menu, click Network check.
The Check network window opens. The entries are grouped (General, PrT, PuT).
2. Select what you want to check the network for.
Section PuT |
|
Element |
Description |
Zones without PuT connection |
The option checks the network for zones without a PuT connectors. It checks for the existence of connectors and whether they are open to PuT transport systems. Note For zones with demand distribution as percentages, the connector shares are also checked. |
Links with PuT-Walk time = 0 |
The option checks the network for PuT Walk links with a time = 0. |
Links with PuT-Aux time = 0 |
The option checks the network for PuT Aux links with a time = 0. |
Links with PuT run time = 0 |
The option checks the network for links with a PuT run time = 0, i.e. links, which are traversed by a line route of a specific transport system which has a link run time of 0s for the transport system and, in addition, a length or link type speed = 0 for the transport system. |
Find line and system routes with zigzags |
This option checks whether the network contains (trivial) zigzag courses on line routes and system routes. If zigzags are found, you can repair them in the Messages window if the served stops can be kept in their order. Alternatively, you can remove zigzags in the network editor (Removing zigzags from a route course) Furthermore, the function finds (trivial) loops in route courses. A loop occurs when the same route point is passed multiple times. Within the loop, the same route points are traversed for outward and return directions. Trivial loops have no other profile points within the loop. After the check, you can repair loops in the message window. You can select the transport systems for the check in a separate window by clicking on the transport systems displayed. |
Vehicle combinations without vehicle unit |
The option checks the network for vehicle combinations without vehicle units. |
Inconsistent couplings |
The option checks the network for couplings that are not consistent. Those are couplings with valid days which do not overlap. If a vehicle journey operates, for example, Monday to Friday and the coupled vehicle journey operates at the weekend only, the coupling has no effect. |
Stop areas with the same node |
The option checks the network for stop areas of the same stop which have the same access node and thus permit direct transfers in zero time. |
PuT connector nodes without stop area |
The option checks the network for PuT connectors which lead to nodes without a stop area. Note We recommend this check if you have selected the Force boarding/alighting at connected node option under Calculate > General procedure settings > entry PuT settings > entry Assignment for the Walk links from/to connectors option. |
PuT connector nodes without lines |
The option checks the network for PuT connectors which lead to nodes with stop areas which are not served by any lines as alighting or boarding is not permitted at any of the stop points. Notes If the connector node has no stop area or no line serves the node, passengers use walk links before / after using the connector. We recommend this check if you have selected the Force boarding/alighting at connected node option under Calculate > General procedure settings > entry PuT settings > entry Assignment for the Walk links from/to connectors option. |
Access and egress at inaccessible stop points |
The option checks if the network contains stop points that do not have a PuT Walk connection to zones, but where at least one vehicle journey stops (access or egress). For each of these stops, the check issues the concerned vehicle journeys. Use the Edit link in the Parameters column to set for which Mode the check should be run. In addition, you can restrict the check to the active vehicle journeys using the Use only active vehicle journey sections as filter for... option. Note Using the repair function in the Messages window, you can prohibit boarding and alighting for the respective vehicle journeys at such stops. |
Invalid chained up vehicle journey sections |
The option checks whether the network contains invalid chained up vehicle journey sections of which origin or destination vehicle journey section do not run on the planned calendar day or the destination vehicle journey section is used repeatedly on the same calendar day. Checks for passenger trip chains with an origin vehicle journey section that does not end at the same stop where the destination vehicle journey sections begins. Forced chainings with an invalid vehicle combination are displayed. |
Lines without a fare system |
The option checks whether the network contains lines that do not belong to a fare system. |
Parallel vehicle journeys of a time profile |
The option checks whether the network contains vehicle journeys that simultaneously use the same time profile during the analysis period. |
Vehicle journey items without vehicle journey sections |
This option checks whether the network contains vehicle journey items that are not covered by a vehicle journey section. A missing coverage may occur if you delete or shorten vehicle journey sections. |
Note: Use the and buttons to select all check options simultaneously or to reset the selection. Use the symbol to reverse the selection. You can also activate several options by selecting them in the window and activating/deactivating them using the shortcut menu or the space bar on the keyboard. You can collapse the General, PrT and PuT sections by double-clicking the section names. |
3. Click the Run selected network checks button.
The check is executed. The result of each option is displayed in the Details column and in the corresponding tooltip. The link in the Messages column takes you to the window of the same name, which contains further information (Messages window). You can correct errors directly.
Note: You can correct errors while the Check network window is open, for example via the Messages window. You can then repeat the check in the open Check network window. |
