Data Center

Traffic Flow

A traffic flow survey is used to survey traffic flows within a closed area, also known as cordon. The basis for this are cross-sectional counts where vehicles with license plates are recognized by BCAs. The images and license plates are only processed on the device and linked to traffic flows using a hashing algorithm, fully GDPR compliant. Source, destination and transit traffic as well as traffic flows at selective nodes or relationships are available for data analysis. Traffic flows can be segmented by traffic classification, travel time and origin by country and region.

Further improvements

• The Data Center can now be used with devices from all Control Center instances

Control Center & Device Update

Counting Line Support for BMC

With this release it is possible to switch dry-contacts of the BMC (and Quido) with Counting Lines in addition to Region of Interest.

For counting lines, the configured dry-contact is closed for a short time interval (approx. 150 ms) as soon as the configured rule is fulfilled, e.g. a vehicle passes the counting line in the “In” direction. E.g. this allows to count the number of passing vehicles by triggering a dry-contact.

Further improvements

• Number plate detection (Parking Mode ANPR)

  • Umlauts such as Ö were output twice under certain circumstances

  • If the “Attach image to event” option is activated, images are always attached to the event as payload even if the license plate was not recognized

  • The event format has been extended and now includes the coordinates of the detected vehicle and the license plate

• Speed Estimate - Accuracy has been improved

• Live Calibration - The visual representation of the object detection (colored outline around the object) is correctly displayed

This release mainly contains bug fixes and minor improvements for Data Center and Control Center. The software on the devices will not be updated.

Data Center

General

• The UI for traffic surveys as a list and on the map has been revised (improvement)

  • Color coding of the traffic survey types

  • Markers on the map are grouped

  • The traffic survey name is displayed on the map

• The tenant logo can be removed (improvement)

• When creating traffic surveys, a double-click was required (bug fix)

• When a device is removed, the associated counting lines or zones are removed as well (bug fix)

Flowing traffic

• The traffic flow chart is exported with a higher resolution (improvement)

• The traffic survery data is displayed correctly if the time and class filters are combined (bug fix)

• The Excel export could not be opened under certain circumstances (improvement)

• The accuracy for the geo position in the Excel export has been increased (bug fix)

Stationary traffic (Parking)

• The API for parking spaces outputs the correct historical parking space occupancy (bug fix)

Traffic Flow

• The formatting of the journey time is now displayed in the format HH:MM:SS (improvement)

• The source and destination traffic is displayed correctly in the summary table (bug fix)

• The API outputs the node from and to_nodes correctly (bug fix)

Control Center

• If the communication error rate between the BMA and BMC is between 1% and 80%, a warning is displayed. If the error rate is higher than 80%, not running is displayed (improvement)

• Even if devices are deleted or moved, the widgets in Data Analytics remain consistent (bug fix)

B101 & B401

The B101 and B401 with passively cooled housings are ideal for installation in control cabinets. Typical solution areas are parking space monitoring and traffic surveys.

The B101 and B401 differ in their performance and therefore in the number of streams that can be processed in parallel.

Device update

Products (BMA, Mobile BMA, BCA, B101/B401)

Update size: ~130MB

Improvements & Bugfixes

• Long tracks are displayed as a continuous line in Live/Track calibration

• MQTT connection establishment does not lead to a delay in image/event processing

• Watchdog for LTE connections

• Corrupt caches are automatically rebuilt

Data Center

Parking - Current and historical parking utilization

Simple configuration of parking spaces, divisible into several groups. These settings are supported:

• Balanced parking, i.e. one or more crossing lines record entries and exits.Manual calibration by the operator is possible.

• Single and multi-space parking, i.e. ROI configured for single or multiple parking spaces.

Internationalization

Data Center is now available in English. The language is automatically selected based on the language configured in the browser.

Robustness

Behind the scenes, we have revised the event processing and infrastructure required for the data center in terms of resilience and scalability. This means that the data center is ideally equipped for increased event and user volumes in the future.

Bugfixes

• Config App - Saving crossings for existing turn-offs possible

• Config App - All ROIs can be added

Control Center

Improvments

Bugfixes

• ANPR-option available for B401

• Correct device connectivity state after moving between tenants

• Devices available after reprovisioning

• Fallback for connection status in case of an Azure infrastructure issue

BERNARD Mobility Controller (BMC) 2.2

The BERNARD Mobility Controller (BMC) serves as an interface between BMA and the control unit of the traffic signal systems, up to 12 potential-free contacts can be switched. The BMC supports up to 4 BMAs. The 2-wire connection cable serves both as a communication channel for switching commands between the BMA and BMC and as a power supply for the BMA. (Data sheet and Operating instructions))

• The configuration is carried out centrally in the browser via the Control Center

• The event trigger "Region of Interest" (ROI) in combination with Rules is supported.

  • Multiple ROIs can be defined. Several rules can be assigned to each ROI.

  • Rules enable contacts to be switched when a person or an object is present (presence). They can be combined with filters for vehicle classes, number of objects or length of stay of the objects.

BMA

• The Classification has been improved, especially the classes Single Unit Trucks and Vans. This affects the Traffic& Parking - Standard and Accuracy+ models.

• Event format extension: In addition to trackId, the trackUuid is also issued. See Event Schema for details.

BERNARD Control Analyser

• GDPR-compliant recording of parking times or country and region of the license plate number

  • Parking times up to 72 hours long

  • No saving of image data on the device or in the cloud

  • No saving of license plates. The license plates are pseudo-anonymized with a hashing process on the devices and anonymized in the cloud after exit matching.\

Control Center

• Display of available or planned device updates\

• All event triggers, focus area and camera stream-related parameters can be easily reset. This makes it easy to reconfigure temporary traffic surveys with the mobile BMA.

• Bug fixes:

  • Configurations are reliably saved.

  • Camera images are reliably displayed in the Firefox browser.

Data Center

• Bug fix for the grouping of the turning movement counts
