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.

void MSEdgeControl::detectCollisions | ( | SUMOTime | timestep | ) |
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::moveCritical | ( | SUMOTime | t | ) |
Moves (precomputes) critical vehicles.
"Critical" are those vehicles that interact with the next junction and all first vehicles. They are not moved, in fact, but their speed along the next path is precomputed.
This method goes through all active lanes calling their "moveCritical" implementation. If this call returns true, the lane is removed from the list of active lanes.

void MSEdgeControl::moveFirst | ( | SUMOTime | t | ) |
Really moves critical vehicles.
"Critical" are those vehicles that interact with the next junction and all first vehicles.
At first, this method goes through all active lanes calling their "setCritical" implementation. If this call returns true, the lane is removed from the list of active lanes. During this call, "myWithVehicles2Integrate" is filled with lanes that obtain new vehicles.
Then, myWithVehicles2Integrate is gone through, calling "integrateNewVehicle" of each of the stored instances. If this call returns true and the lane was not active before, it is added to the list of active lanes.
