Configuration of a Traffic Flow survey

Configuration of a Traffic Flow survey

After successful installation and configuration of the BCA, open the web browser and enter the following address:

https://datacenter.bernard-gruppe.com

You can log in to the website with your customer login. If you have problems logging in or have forgotten your password, Support Center can help you.

To create a survey, first open the highlighted „Config App“ tab at the top right of the menu bar.

Selection of the Tenant

Next, select the desired tenant to continue with the configuration. The tenant can be used to group measurement series. If you require more than one tenant, please contact customer service. Switch to the “Traffic Flow” tab.

Add Survey

You have the option of filtering your surveys by date or text content. It is therefore advisable to select the name of the survey so that it can be easily found later and, if necessary, different groupings are possible using the text filter (e.g. location/project number).

A new survey can be created using the “Add element” button. A new field is created in which the name of the survey must be defined. Save the process with the blue button with the memory card symbol.

Figure 2: Adding a new survey.

To edit a created survey, select the relevant survey by clicking on it. A user interface then opens below the list of created surveys. The selected survey can be configured using the highlighted “Edit” button.

Definition of key data (location, date und traffic types)

A window opens with the key data - Name, Alias, Start date, End date, Time zone and Traffic types.

Figure 3: Configuration of a selectet survey.

Table 1: Definition and key data of a survey

Name

Describes the name of the survey that you initially assigned when creating the survey. If required, the name of the survey can be edited in the corresponding field.

Note!

As it is possible to filter the surveys by name, it is recommended to select a unique name.

Date

The start and end date define the period for the data evaluation. For the start and end date, 00:00 is automatically selected as the time, with the end date including the selected day.

Example:

For a survey on the 01.01.2023 from 0:00 to 23:59, the start date and end date are both 01.01.2023.

Alias

Describes a unique name with which the results of the survey can be retrieved via the API. The alias of the survey can be edited in the corresponding field. Note: Only alphanumeric characters (a-z, A-Z, 0-9) are valid here.

Time Zone

The time zone is set to the “Europe/Vienna” region by default.

It is recommended to select the local time zone of the survey in the menu.

Traffic types

The traffic types are the vehicle classes that are to be included in the evaluation for this survey. By pressing the Ctrl key, several traffic types can also be selected for a single survey.

In order to make the application possibilities of the evaluation more flexible, the selection of the survey can also be adjusted retrospectively. Note: Only traffic types with license plates are listed.

After successfully configuring the key data of the survey, save this process by clicking the save button.

Add/edit cameras

The next step is to assign the BCAs used to the survey. To do this, open the selection window by clicking on “Add/edit cameras” (see Figure 6). Add all the BCAs that you are using or have used for this survey.

Figure 4: Add/edit cameras

Once you have selected your BCA, click on “Add selected camera” and it will appear in the “Cameras” table (see Figure 7).

Configuration of a cordon

Node

A traffic flow survey should consist of at least 2 nodes. Open the “Survey layout” section and navigate to the correct position on the map. Now add a new node using the pen tool.

Figure 6: New node

Table 2: Node types

Node types

Cordon

Node for incoming and outgoing traffic in a cordon (closed area).

Trips that are evaluated always start and end at a cordon. They are then evaluated as transit traffic. If a journey has only been detected at a start node, it is evaluated as destination traffic in the area.

Midpoint

Nodes within the cordon.

Trips that are classified as transit traffic can be broken down into sub-routes in more detail using center nodes.

The following figure shows an example traffic survey with a cordon and which node types should be configured where:

Figure 7: Example node types

Nodes A, B, C and D are cordon nodes. This is where the tracking of trips through the cordon, i.e. the area defined by the nodes, begins and ends.

Nodes E and F are midpoints and are used for a differentiated analysis of the sections over which the through trips have passed. For example, through traffic may have traveled from A to B on a direct route or via the midpoint E. This differentiation is possible using the “Show subjourneys” option in the evaluation.

Trigger

The node can be edited and triggers configured using the selection tool. Select the crossing line trigger of the corresponding device.

Figure 8: Trigger configuration

Table 3: Trigger parameter

Start direction and End direction

Available for cordon type nodes. Shown as an arrow between nodes.

  • Start of journey describes the beginning of a traffic flow, into the cordon.

  • End of journey describes the end of a traffic flow, out of the cordon.

  • The direction is defined by the counting line direction.

Example:

  • The trigger of the node Geyrstraße defines the Start direction.

  • The trigger of the node Amraser See Straße defines the End direction.

The used directions are defined by the Counting Line of the Control Center.

  • In this example of the Geyrstraße defines the Counting Line the direction IN (towards the city center) the direction into the cordon.

Journey time Min/Max

Min/max values between accounts can be specified for the traffic flows. Traffic flows outside the specified value ranges are not taken into account for the data analysis. A calculator based on speed and air distance is available.

Figure 9: Journey time Min/Max

Publish survey

If the configuration is error-free, the survey can be published. A published survey can now be viewed in the “Data App”.
