Stores edges and lanes, performs moving of vehicle.
In order to avoid touching all lanes, even the empty ones, this class stores and updates the information about "active" lanes, those that have at least one vehicle on them. During longitudinal movement, this can be simply achieved through return values of the MSLane-methods, signalling either that the lane got active or inactive. This is but not possible when changing lanes, we have to go through the lanes, here. Also, we have to add lanes on which a vehicle was inserted, separately, doing this into ("myChangedStateLanes") which entries are integrated at the begin of is step in "patchActiveLanes".

void MSEdgeControl::changeLanes | ( | SUMOTime | t | ) |
Moves (precomputes) critical vehicles.
Calls "changeLanes" of each of the multi-lane edges. Check then for this edge whether a lane got active, adding it to "myActiveLanes" and marking it as active in such cases.

Detect collisions.
Calls "detectCollisions" of each lane. Shouldn't be necessary if model-implementation is correct. The parameter is simply passed to the lane-instance for reporting.

void MSEdgeControl::executeMovements | ( | SUMOTime | t | ) |
Executes planned vehicle movements with regards to right-of-way.
This method goes through all active lanes calling their executeMovements method which causes vehicles to update their positions and speeds. Lanes which receive new vehicles are stored in myWithVehicles2Integrate After movements are executed the vehicles in myWithVehicles2Integrate are put onto their new lanes This method also updates the "active" status of lanes
