In GoodVision, a traffic movement is the flow of individual vehicles or pedestrians on one line (in one area) or between two or more lines/areas in a specific direction.
Define your traffic movement
On the Describe page, draw LINEs or ZONEs to your traffic scene, which will represent the entry and exit areas of your traffic movement.
Then hit “+NEW” under the “Movements” tab and drag your pointer from the entry area to the exit area to define the direction of the traffic movement flow and press "Save" when complete.
Left turn above filters all traffic objects going from ZONE 1 to ZONE 3 (in that specific direction)
As a next step, you will see a New traffic movement settings window. Here you can name your movement, change selected filters, swap their order, or delete some if needed. You can also redefine the path completely by clicking on "change objects" button.
Optionally, distance between the filters (in meters or feet) can be entered for speed estimation (kph or mph). By checking the checkbox Create total volume widget, you can create an analytical widget on the Analyze page straight from this dialog.
There is also another checkbox available for some movements - Smart Corridor. This special feature can be applied only for movements between two lines which create a corridor for the traffic movement. Smart Corridor can link some of the potentially disconnected vehicle trajectories going the chosen movement direction and thus bring volume counts closer to the reality, especially for recordings with lower quality, low camera or minor obstacles. Get to know more about this feature here.
After saving it, the movement bean is created on the right panel. By clicking on the movement, the bean becomes selected (green) and only the trajectories that fulfill this traffic movement will be shown on the scene.
ZONEs or LINEs included in that selected movement will have green borders and the movement direction arrows will be animated.
You can always edit all the settings if you need or delete given movement using buttons that are highlighted in the picture below.
Defining complex movements
GoodVision allows you to chain multiple detection areas to create even very complex movements. Simply drag your pointer over the detection areas which you’d like to include in the movement.
Getting the traffic data
Finally to analyze the traffic data defined by your movements, events or scenarios, create appropriate widgets on the Analyze page. See our guide on How to create widgets for the traffic volume, travel time, peak periods or various visual maps to get the most of the Video Insights platform.
