Overtaking on bidirectional roads

[akegermany]

Movsim aims at modeling all generic situations in traffic. Overtaking on bidirectional roads is such a generic situation which we should handle.

At first the movsim network model has to be extended in a way that the opendrive format for left and right lanes is taken into account. Then we need a mapping to two RoadSegments which share the same RoadMapping as "peers" in counterflow directions. That is: The network of road segments is a directed graph and we need a mapping from a road-ID to a pair of ids for both directions.

Having this datastructure the model for the discrete decision has to be implemented taking into account the vehicle from the counterflow direction.

Last but not least the visualization needs to handle these issues (drawing the vehicles in the correct driving directions (a vehicle could use a road segment in the counter-driving direction for overtaking. The experience showed that visualization is a perfect tool for model development.

It would be interesting which simulators actually do implement such overtaking maneuvers.
