MATSim Code

deleted, there is another file with just differs in the capitalization of the filename.

nodes are inactive by default. this is okay, as they will be activated as soon as a vehicle enters a buffer, and as long as vehicles cannot start in buffers, all is well.

Bugfix: link is set inactive in finishInit(). Otherwise, it could happen that links got not correctly activated when a new iteration started.

adding NUMBER_OF_THREADS to output, the parameter itself was already available for some while

Optimization: Links can now be inactive if there are only parked vehicles, but they have to register themselves in QueueSimulation.setActivationLink() so they are activated again at the right time when a vehicle wants to depart. Using a LinkedList (Queue-Interface) instead of an ArrayList for QueueLink.vehQueue, this seems to speed up things a little bit. Removed synchronized-statements in QueueLink, as the QueueSim is still single-threaded. Got rid of QueueLink.buffercount in favor QueueLink.buffer.size(). Other smaller code cleanups.
The order of events changed in the OnePercentBerlin10sTest, because the links with only parked vehicles are now activated/deactivated and are thus in an other order in the internal QueueNetworkLayer.simLinksArray. But if the old and new events-files are sorted, they are equal.
The changes reduce the execution time of OnePercentBerlin10sTest to about 60% of the time before.

code cleanup. made members non-static.

removed additional linebreak in printMemoryUsage()

added option to disable the creation of the leghistogram.png with method setCreateLegHistogramPNG(). The creation was especially expensive in small scenarios like equil-net.

nodes are now deactivated when no incoming buffer has cars on it to speed up simulations (finished the work of Kai from 2007-11-19) and activated again by QueueLink as soon as a car is placed in a buffer.

removed old GPL-Header, some code cleanup / optimization
