TrafficXRoads: Guide 

means that all the expression, defined time modes etc… will keep being processed. 
 

 

 

 

FLOW  does  not  directly  control  the  cameras  but  instead  acts  as  a  passive 
receiver  of  the  camera  position  and  zoom  information.  Based  on  this 
information the different analytics get activated to analyze the newly incoming 
trajectories. 

Detection of traffic events 

The FLOW framework enables you to define detections of very complex traffic events 
including interactions between objects. The generic FLOW description can be found here 
(https://intercom.help/datafromsky/en/collections/2019942-flow-real-time-
monitoring),  including  different  tutorials.  In  this  document  we  will  focus  only  on  the 
selected  basic  tasks  that  can  be  used  in  detection  systems  for  traffic  control.  The 
Definition of detection of traffic events is done in the 

Definition

 tab.
