[sumo-user] Using SSM for collision recognition

[Lu <xxxxx@xxxxxxx>]

Hi.

I want to get collision probability and collision point (coordinates) through traci using SSM. 

"https://sumo.dlr.de/docs/Simulation/Output/SSM_Device.html#restricting_ssm_device_to_edges_and_junctions" 

Are there only minTTC, minPET, and maxDRAC parameters that can be obtained through traci? 

Also, I would like to know about the possibility of collision between vehicles that cannot be connected as in the attached photo. 

Which method is more efficient using SSM and traci? 

Also in the output of SSM: <conflict begin="5.74" end="11.00" ego="vehicle_0" foe="vehicle_3">

Begin and end say <log-begin-time>, <log-end-time>, but I'm curious what the standards are.

 

Thanks!
