Detailed Description

Inserts vehicles into the network when their departure time is reached.

Holds a list of vehicles which may be filled by vehicles read by SUMORouteLoaders. Tries to emit vehicles departing at a time into the network as soon this time is reached and keeps them as long the insertion fails.

If a vehicle is emitted, the control about it is given to the lanes.

Vehicles are not controlled (created, deleted) by this class.

Todo:: When a vehicle is deleted due to waiting too long or because of vaporizing, this is not reported anywhere

◆ tryInsert()

int MSInsertionControl::tryInsert	(	SUMOTime	time,

Tries to emit the vehicle.

If the insertion fails, it is examined whether the reason was a vaporizing edge. If so, the vehicle is deleted. Otherwise, it is checked whether the time the vehicle had to wait so far is larger than the maximum allowed waiting time. If so, the vehicle is deleted, too. If both does not match, the vehicle is reinserted to "refusedEmits" in order to be emitted in next steps.

Parameters

[in]	time	The current simulation time
[in]	veh	The vehicle to emit
[in]	refusedEmits	Container to insert vehicles that could not be emitted into

Returns: The number of emitted vehicles (0 or 1)
