Re: [sumo-user] Opposite side overtaking collisions

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 (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

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.

Snapshot: 

 

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
