Simulation of Urban MObility / News: Recent posts

version 0.21.0 released

Dear friends and colleagues,
we proudly present the latest release of SUMO.

The major enhancements include:

) Support for pedestrian dynamics:
Integrated into the previously existing inter-modality model, pedestrians may now have own lanes and use a variable dynamics model to move. Uncontrolled as well as controlled crossings are supported and tools from the suite (mainly netconvert) have been extended to support the new structures accordingly. More information can be found at http://sumo-sim.org/userdoc/Simulation/Pedestrians.html
) Support for Amitran file exchange formats:
The Amitran project defined a set of exchange formats for road networks, O/D-matrices, vehicular trajectories, and network states. These file types are now supported by the sumo applications.... read more

version 0.19.0 released

Dear friends and colleagues,

we are happy to announce the latest release of SUMO.
Below is a list of the major changes since the previous release. You can
find the full list here.

  • Bugfixes

    • Simulation
      • fixed bug which caused vehicles to brake without good reason
      • flow on a highway will no longer come to standstill just to let vehicles from an on-ramp merge.
      • vehicles now manage to change to the necessary lanes much more often and thus avoid having to stop and block upstream traffic.
      • vehicles now use all lanes of a multi-lane roundabout instead of only the outer lane.
      • fixed several bugs which caused instantInductionLoops to miscount vehicles
      • fixed error in a car-following related formula which was causing collisions... read more

version 0.17.0 released

Dear friends and colleagues,
we proudly present the latest release of SUMO. Major changes in this
release include:

Simulation
- added support for traffic-actuated traffic lights
- added support for microscopic calibrators. These trigger-type
objects can be used to increase or reduce traffic volume and to
regulate speeds at selected edges. Using calibrators it becomes
possible to calibrate a simulation according to known traffic
measurements (i.e. from real-life induction loops) without using
TraCI. For usage examples see the test suite at
tests/sumo/extended/calibrator.
- added a car following model which respects slope (kraussPS), your
network needs z-coordinates then... read more

version 0.12.0 released

Dear colleagues, friends, all,

We want to inform you about a new SUMO release - 0.12.0.

The major change is the added possibility to simulate using time steps below 1s; this was achieved by a rework of the microsimulation loop and moving from floating point representation of time to integer milliseconds. As a result, the time steps are "clean" now - 0.1 seconds are 0.1 seconds (100ms in fact) and not a blurred floating point number.... read more

version 0.11.0 released

Dear friends, dear users,

A new version of SUMO (Simulation of Urban MObility) - 0.11.0 - is available for downloading.

The major changes for this release are:
* many extensions to the TraCI interface
* new network and configuration format

A more complete list of changes is available at:
http://apps.sourceforge.net/mediawiki/sumo/index.php?title=ChangeLog

The changes in formats mean that you will need to rebuild your networks and configurations. We provide two python scripts to support this at tools/net/0103to0110.py and tools/10to11.py.... read more

version 0.10.3 released

Dear friends, dear users,

A new version - 0.10.3 - is available for downloading.

Releasing it has two major reasons:
* the request for using xerces 3.x - the support may be enabled using the configure script
* additional work has been put into the simulation of inner-junction areas

A more complete list of changes is available at: http://apps.sourceforge.net/mediawiki/sumo/index.php?title=ChangeLog#Version_0.10.3... read more

new 0.10.2 windows binary package

As the original package included a false version of the xerces library, we had to upload a new windows binary package for the 0.10.2. You may find it within the dowloads area as "sumo-winbin-0.10.2.1.zip"

version 0.10.2 released

Dear friends, dear users,

We want to announce a new SUMO version - 0.10.2.

Again, most of the work concerned debugging and consolidation. Besides, the major changes are:
* noise and pollutant emission models based on Harmonoise/HBEFA
* a validated and tested TraCI, working on both Windows and Linux
* extension of the inner-junction traffic for dense situations
* debugging of interaction with rerouters and vss in GUISIM... read more

version 0.10.1 released

Hello,
this is our late night release which just fixes
a critical bug in collision handling which prevented a shiny start into the 0.10 season.

Regards,
Daniel and Michael

version 0.10.0 released

Dear all,
the major changes for this release are:
* internal lanes are default (vehicles do not jump over junctions)
* changes in the route format ("edges" attribute)
* possibility to define route and vehicle type distributions

It may be necessary to rebuild your networks / routes.

Have fun,
Daniel and Michael

version 0.9.10 released

The new release solves several issues encountered in version 0.9.9. The main one is the improper handling of networks with internal edges which lets most of the enclosed examples prompt an error message.

In addition, the most important changes are:

- solving issues with bus stops (reported by Gerrit Lammert - thanks)

- patching problems with vehicles being black by default

- a change in the network format.... read more

version 0.9.9 released

Dear all,

we just released version 0.9.9.

The major changes are having TraCI enabled as default (including support for guisim), making SUMO buildable under Linux 64bit, and beginning implementing the Specification (http://sumo.sourceforge.net/wiki/index.php/Specification).

Have fun,
Michael & Daniel

version 0.9.8 released

Dear users,

Again, it's time for a new SUMO-release (0.9.8). The list of changes is available at http://sumo.sourceforge.net/wiki/index.php/ChangeLog#Version_0.9.8. Before listing the most important ones, we would like to thank all those who have contributed by sending bug-reports.

This will probably be the last 0.9.x-version of SUMO. In the next time, we will try to adapt the changes in the API as proposed in http://sumo.sourceforge.net/wiki/index.php/Specification. This will affect the behaviour of the simulation in several parts and change some input and output files. Because several people are co-developing SUMO, we would propose to discuss these changes on the developers-mailing list (sumo-devel@lists.sourceforge.net).... read more
