Using additional Polygons and POIs within the Simulation
Since version 0.9.4, it is possible to include geometry files into the additional files section of a simulation configuration which contain definition of polygons or points of interest. These shapes are currently meant to improve a simulation's appearence and to allow an easier debugging. No special interaction with them is implemented, yet.
Both polygons and points of interest may be located within a "layer". Shapes with lowest layer values are below those with a higher layer number. The network itself is drawn as layer 0. An additional file may contain definitions for both points of interest and polygons.
Geometrical objects may either be defined "by hand" or imported using POLYCONVERT. A valid geometry-file can be given to SUMO as one of the additional files (option: --additional-files <FILE>). For usage within SUMO-GUI, you have to add it to the list of additional files to load within the used SUMO configuration file.
Definitions
The geometrical objects (POIs, polygons) are stored one by one into an "additional file". Currently, the root element may arbitary.
Polygon Definitions
A polygon is defined as following: <poly id="<POLYGON_ID>" type="<TYPENAME>" color="<COLOR>" fill="<FILL_OPTION>" layer="<LAYER_NO>" shape="<2D-POSITION>[ <2D-POSITION>]*"/>
These attributes have the following meanings:
| Attribute Name | Value Type | Description |
|---|---|---|
| id | id (string) | The id (a unique name) of the polygon |
| color | color | The RGBA color with which the polygon shall be displayed; see <COLOR> for details |
| shape | 2D position list | The shape of the polygon |
| fill | bool | An information whether the polygon shall be filled; optional bool, default: false |
| layer | float | The layer in which the polygon lies; optional |
| type | string | A typename for the polygon. |
| imgFile | string | A bitmap to use for rendering this polygon |
POI (Point of interest) Definitions
A point-of-interest is defined as following: <poi id="<POLYGON_ID>" type="<TYPENAME>" color="<RED>,<GREEN>,<BLUE>" layer="<LAYER_NO>" [(x="<X_POS>" y="<Y_POS>") | (lane="<LANE_ID>" pos="<LANE_POS>")]/>
It means that the position a point-of-interest is located at may be given either using explicite x/y-coordinates or a lane name and a position on this lane. So, the attributes have the following meanings:
| Attribute Name | Value Type | Description |
|---|---|---|
| id | id (string) | The id (a unique name) of the polygon |
| color | color | The color with which the poi shall be displayed; <RED>, <GREEN>, and <BLUE> must be floating point numbers between 0 and 1. They are devided using a ',' (no space); optional, default "1,0,0" |
| x(*) | float | The position of the poi along the x-axis in meters |
| y(*) | float | The position of the poi along the y-axis in meters |
| lane(*) | id (string) | The name of the lane the poi is located at; the lane must be a part of the loaded network |
| pos(*) | float | The position on the named lane at which the poi is located at |
| lon(*) | float | The geo-position of the poi along the east-west axis in degrees |
| lat(*) | float | The geo-position of the poi along the north-south axis in degrees |
| fill | bool | An information whether the polygon shall be filled; default: false |
| type | string | A typename for the poi. |
| layer | float | the layer of the poi for drawing and selecting. |
| imgFile | string | A bitmap to use for rendering this poi |
| width | float | width of rendered image in meters |
| height | float | height of rendered image in meters |
| angle | float | angle of rendered image in degree |
(*) Either x/y or lane/pos or lon/lat must be given
