We are very happy to announce a new release of MATSim!

This release is a major step forward from the last release, including the work of over 1.5 years of intensive development. It includes many new features (like a new visualizer, simulation of roadpricing-scenarios, automated comparison with counting stations, re-planning modules for secondary location choice, ...) as well as many improvements to existing functionality (major speedups in nearly all areas, reduced memory consumption, graphical output of default analyses, ...). 

Changes

The following lists only contain the most important changes, and are by far not complete!

New Features

• Integrated comparison with counting stations, output as html, pdf, kml
• New visualizer (see class org.matsim.run.OTFVis as well as user-documentation)
• Simulate roadpricing-scenarios (distance, area, cordon)
• New replanning modules: Secondary Location Choice, Planomat
• Regenerate snapshots from events-files (note: events do not contain the complete internal state of a simulation. The plotted vehicle positions are therefore not the real positions as calculated by a simulation, but positions calculated from the available events). See class org.matsim.run.Events2Snapshot

Feature Improvements

• Java Mobsim / Queue-Simulation: Major speedup of 30 to over 100%, depending on scenario
• Improved positioning of vehicles in snapshots
• Faster router (A*-Landmarks) is now used by default.
• Reduced memory-consumption
• misc. speed-improvements in events-handling, most noteably when running big scenarios

Improvements for users who write code based on MATSim

• Improved handling of config-settings within the code
• Rewrote scoring functionality to allow custom scoring functions to be used.
• Improved available API in many areas such to allow easier overwriting/extending of functionality.
