Fixed bug in the computation of safe velocities. Sometimes the
velocity was too high (causing collisions) but most times it was
too low (degrading traffic flow).
Vehicles now move to the right lane after passing instead of
staying on the passing lane. (see #1139)
Fixed simulation crash related to lane-changing.
Fixed bug where vehicles would no longer stop on the correct
lane if they already stopped on the wrong lane.
Fixed bug which would cause collisions due to unsafe lane
changes
Fixed crash when terminating the simulation while vehicles were
performing continuous lane changing maneuvers (using option --lanechange.duration)
Fast vehicles can now be correctly inserted closely in front of
slow vehicles #1176.
Rerouting fixed for vehicles which are on internal lanes when
the rerouting is requested #1128.
sumo-gui
Fixed crash when using the object locator #923 on some versions of
Ubuntu].
Fixed bug where brake lights were shown even though the vehicle
was not braking
Fixed bug where train carriages where sometimes drawn onto the
wrong lane
The vehicle option 'select foes' now works correctly for foe
vehicles on internal lanes
Fixed rare graphical glitch when drawing concave junction shapes
Fixed drawing of segmented vehicles (trains) which are longer
than their departPos
netconvert
Fixed bug which gave some links the wrong priority thus causing
collisions (see #1096)
Fixed crash when specifying connections from/to edges which are
removed during network building
OSM import no longer fails when encountering empty strings in
places where numerical values are expected.
Fixed bug where permissions involving the vClasses custom1
and custom2 were not written correctly.
Fixed bug where connections from a lane were sometimes indexed
in the wrong order.
Disconnected nodes can no longer be joined into a cluster when
using the option --junctions.join.
Fixed (crash #1177) when using option --ramps.guess
option --ramps.guess no longer creates ramps if one of the involved
connections is a turnaround
traffic lights which get new programs are no longer renamed (see #1157)
DFRouter
Fixed crash/infinite loop when using option --guess-empty-flows. Use of this option
is not (yet) recommended (see #1198)
JTRRouter
Fixed handling of empty flows (no vehicles) together with a
specified start time (see #1109)
TraCI
instantInductionLoops are no longer included when calling
calling traci.inductionloop.getIDList()
Tools
Fixed bug which prevented traceExporter.py from running
Fixed bug which caused all speed values in NS2 output to be 0
Fixed bug which prevented traceExporter.py option --penetration<FLOAT> from taking
effect
The summary of teleporting vehicles now lists all teleports
according to their reason
Vehicles now perform an emergency braking maneuver to prevent
driving across a red light. If this happens in a simulation it
usually indicates that the length of the yellow-phase is to
short in relation to the road speed and the braking
capabilities. To enable driving across red lights, additional
TraCI flags were added (see below).
Improved intersection model which results in less conflicts
between vehicles with intersecting trajectories while on
internal lanes.
Added a first version of the
PHEMlight emission
model (contribution of TU Graz)
Rerouting now keeps existing stops and adds new stops which are
part of the new route even in cyclic routes
sumo-gui
Reworked drawing of trains to have more realistic carriage lengths.
Also some busses are drawn with flexible segments now.
The vehicle parameter dialog now lists the maximum speed of the
vehicle's type and the the time headway to the vehicle's current
leader
added vehicle coloring mode by time headway
Traffic light colors now distinguish between green major (code
G) and green minor (code g) by coloring the minor
state with a darker color.
The lane color scheme by vClass now gives fine-grained control
over coloring by using the permission bitmask
to select the color.
Added menu option Edit->Select lanes which allow...->vClass.
Together with the street-coloring option by selection this
allows an easy overview of the road network permitted for a
given vClass.
Added junction visualization option to disable drawing of
junction shapes.
The vehicle coloring mode by max speed now factors in the
speed limit on the current lane and the speedFactor of the
vehicle. The same color thresholds as in coloring by speed are
now used.
netconvert
added option --osm.elevation<BOOL> which imports elevation data from OSM input
(default false).
Conflicts between connections originating from the same edge are
now recognized. This can be used to model interaction between
right turning vehicles and straight moving non-vehicular traffic
on a lane further right.
improved the heuristic for determining junction clusters to be
joined when using option --junctions.join. This results in fewer invalid joins.
Candidate clusters for manual intervention are indicated.
TraCI
added method traci.simulation.convert3D() which
converts a road position to either x,y,z or lon,lat,alt
added additional bits to the traci command Change Vehicle State/speed mode to
configure the behavior at intersections. This can be used to
make vehicles ignore right-of-way rules and also to force them
to drive across a red light.
it is now possible to retrieve the leading vehicle within a
specified range Vehicle API specification
a vehicle may be added using a full specification (which is
available via XML input)
Tools
added tool xml2csv.py which
converts all of the XML-output files written by SUMO to a
flat-file (CSV) format which can by opened with most
spread-sheet software
added tool csv2xml.py for the
opposite conversion, requiring an XML schema and also for
conversion to Google's protocol buffers
xml2protobuf.py
osm/osmGet.py now supports retrieving very large areas by
bounding box using the option --tiles<INT>. (previously this option was only
supported together with option --oldapi which has severe size limitations)
added option --vclass to
randomTrips.py which
ensures that generated trips only depart and arrive at edges
permitted for vclass
randomTrips.py now
recognizes the network fringe even if the network contains
turn-around connections (An edge belongs to the fringe if it
contains only incoming or outgoing connections excepting
turnarounds). This is important when using the option --fringe-factor<FLOAT> for
generating plausible through-traffic in small networks.
fixed documentation of of command slow down: It changes speed
smoothly over the given number of milliseconds (in contrast to
command speed which changes using maximum
acceleration/deceleration).
All Applications
Added option --xml-validation<STRING> with possible values never, always and auto
defaulting to auto. This causes all input files to be
validated against their respective schema, provided the
schema-URL is declared in the toplevel XML-Tag (always
requires the schema-URL to be present).
Added option --xml-validation.net<STRING> to all applications which read
.net.xml-files which works like
option --xml-validation<STRING> but applies only to sumo networks (default never since
network validation is computationally expensive).
