Hi Don,
we have been working on problems with respect to opposite
driving/overtaking in the last months to years. Please first update to the
latest version
<https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_release_version_1180>
(v.1.18) if possible and check if your problem persists. If yes, please
provide the files of a minimal failing example for further investigation.
Best regards
Mirko

Betreff: [sumo-user] Opposite side overtaking collisions

Hi,
I have modelled a 5x5 grid with 200m edge lengths and priority
intersections. All edges are two-way two-lane roads (one lane in each
direction of travel). All lanes are modelled as lefthand with a speed limit
13.89m/s. netconvert command used to guild net.xml file:
netconvert --node-files=fivebyfive.nod.xml --edge-files=fivebyfive.edg.xml
--output-file=fivebyfive.net.xml --lefthand --no-turnarounds
--opposites.guess true
The vehicle types are all modelled using default settings.
The problem is there are frontal collisions between vehicles when
overtaking close to intersections. I have played around a bit with the
'lcLookaheadLeft' (I presume these work as usual in lefthand traffic?)
parameter, but this problem persists.

Can you please let me know how to rectify this? - I'm using SUMO-1.8.0
I have attached the .net.xml file and .rou.xml file herewith.
Thanks & regards,
Don
