Observed in bicycle scenario, where a car cuts a bicycle. The car enters junction first due to its higher acceleration and is (wrongly) priorized.

Conflict flags are missing in the .net.xml. Also, the signal plan should have green minor for the car.
This cannot be solved via conflict flags as it would have strange consequences for regular vehicle traffic. The conflict is strictly limited to the sublane case where straigth going bicycles are positioned to the right of the right-moving cars.

Two related situations are already working:

  • when the bicycles have their own lane (this conflicht is flagged by netconvert)
  • when two cars from the same edge have the same follower edge but different target lanes and their paths cross (this is handled in MSLink via mySublaneFoeLinks

Something along the lines of the second solutions is needed for this.
