[sumo-user] Emergency vehicle overtaking other vehicles

[Luke Kakadukl via sumo-user <sumo-user@xxxxxxxxxxxxxxxxxxxxx>]

Hello,
I'm developing a simulation where emergency vehicle (EV from now on) needs
to drive from point A to point B in the shortest time. I did configure
special vehicle type where I use this settings:

<vType id="intervention_vehicle"
       vClass="emergency"
       accel="3.3"
       decel="5"
       sigma="0.5"
       maxSpeed="70"
       speedFactor="1.5"
       color="1,0,0"
       guiShape="emergency"
       length="4.8"
       lcStrategic="100"
       lcCooperative="0.0"
       lcSpeedGain="100"
       lcKeepRight="100"
       latAlignment="left"
       lcPushy="1"
       lcAssertive="1"
/>

I'm facing with a problem that EV does not overtake all the vehicles ahead.
I have developed logic to slow down vehicles ahead of EV to force
overtaking, but this does not always happen. It is strange because there is
no traffic in opposite direction and EV could overtake vehicle with no
problem.

Second question I have is: how can I force overtaking in junction, where
traffic light in EVs direction is red and one or more vehicles are already
in junction queue (in EV's direction)? In that case EV is waiting for a
clear way and only then it continues its path.

Thank you in advance for your reply.

Best regards,
Luka
