VCloud.ai Traffic Intensity Determination VCA
Traffic - Module of Traffic Intensity Determination
Main functionality
• Determinate the level of carriageway and sidewalks load at different times of day
• Monitor the traffic in shopping centers and other premises with considerable congestion of people
• Determination of cars and trucks, public transport, motorcycles, bicycles, pedestrians, etc. traffic intensity.
Product Description
The Traffic module is intended for the calculation of intensity and determination of traffic structure according to the video image. Video arrives directly from surveys and special cameras online.
“Traffic” module can be used for:
• Prevention of traffic jams or excessive congestion of people formation on roads and infrastructure facilities;
• Forecasting of streets, roads, or areas load depending on the time of day, a season or day of the week;
• Determinations of optimal routes for the couriers, transport, or personnel transportation movement to minimize the risk of a hit in traffic jams;
• Determinations of supermarkets, shopping centers passability level.
Basic data which are used by module:
• Determination of intensity, quantity, and structure of vehicles on certain location/street/area per time unit
• Analysis of vehicles and people traffic on the basis of the images received from surveillance cameras

Analysis
In order to open the Traffic analytics, select Traffic in the left menu and pass to the Analytics section.
In the Analytics section, you can customize analytics. The page displays a list of analytics with the status and the ability to add, edit, view, or delete analytics.
There is a search field at the top of the page. Here you can filter analytics by the following parameters:
| Field name | Description |
|---|---|
| Name | Analytics name or part of a name can be entered in this field |
| Status | Select the Analytics status from the drop-down list - All, Active, or Stopped |
To start the search click on the Find button. To clear the fields click on the Reset button.
The list of analytics is shown in the table below.
Analytics Adding
In order to add new Traffic analytics, press Add Analytics in the upper right corner of the page.
The Traffic analytics setup process consists of 3 Steps.
Step 1 - General
First of all, it is necessary to select a video stream. Click on the Video field and select the camera name from a list.
You can also enter the part of the camera name in the Search field to find the necessary video stream faster.
On the right side of the window, you can see the video stream preview and information about Camera name and Address, Time Zone, Resolution, Codec, and Type.
When the video stream is selected press the Set Video Stream button.
By pressing the Update Video Frame button you can see a frame in real-time in the field of frame addition.
It is possible if a video stream was selected.
To add analytics it is necessary to set up the following parameters:
| Parameter | Description |
|---|---|
| Tracker Sensitivity | Move the slider to the left (to decrease) or to the right (to increase) the tracker sensitivity. Possible range from 1 to 8, the value is 4 by default |
| Update Frequency | Enter the interval between analytics value updates in seconds. Possible range from 1 to 100 sec |
| Object Type | Select object type (person or transport) for traffic tracking |
| Recognition Options | Parameters on which the chosen object recognition is performed |
Recognition Options
Add lines to the area of interest. This function allows tracing the object traffic.
Each line appears in the middle of the area by default.
Move the line markers to the desired place (as in the example) to set the line perpendicular to the intended objects' movement.
Then set the traffic accounting direction. For this purpose click on the Change Direction button. The arrow will change its direction after each click on the button.
If you use two-way directions - determine the direction of Entry and Exit by moving the slider to the left or right side.
Note: If you use one-way direction, the Entry/Exit slider is unavailable.
Finally, if you have chosen the Transport object type earlier, check the boxes next to the desired objects for traffic counting in the Objects section.
Note: If you have chosen the Person object type, the section Objects is unavailable. If you need to add more lines with different rules, click on the Add Rule button.
If you want to delete some lines, click on the Delete Rule button.
To pass to the next step, click on the Next button in the upper right corner of the page
Step 2 — Hardware
Now it is time to customize Hardware options. System users can change the following parameters:
| Parameter | Description |
|---|---|
| Hardware | Select one of the technologies - CPU or GPU acceleration |
| Decoding | Select the hardware decoder from the drop-down list - CPU, Intel, Nvidia |
| Optimization | Select the optimization parameter from the drop-down list (for CPU - CPU (no optimization), Open VINO; for GPU - CUDA (no optimization), cuDNN Half (FP16), Tensor RT) |
| FPS | Enter the desired number of frames per second in the field for detection. The recommended value is 25 |
When all necessary parameters are selected, go forward to the last step by clicking on the Next button in the upper right corner of the page.
Step 3 - Notifications
Finally, it is possible to customize Notifications.
There are two main options for sending notifications:
• If you check the box next to Internal notification, the system sends all notifications to the Events section of the module;
• If you check the box next to Send events to Event Manager, the system sends all notifications to the Event Manager and then to external resources.
Note: You can choose one of them or use both simultaneously.
If you check the box next to Send events to Event Manager, it is necessary to fill in the following fields:
| Field name | Description |
|---|---|
| Events | Select the event for which notifications will be sent from the drop-down list. |
| Extra Options | If necessary, it is possible to add additional parameters for further use when event creating. Fill in the parameter and value fields. |
To add more parameters, click on the Add Options button.
To remove parameters, click on the Delete icon.
If you want to make changes to previous steps, click on the Back button in the upper right corner of the page.
When the analytics setup is complete, click on the Save button in the upper right corner of the page to save changes and create the analytics.
