1、概览
sumo-gui和sumo有着相同的功能，仅仅是拥有图形化的界面。
目的：仿真一个特定的脚本
系统：在Linux/windows上测试过，打开一个窗口
输入：sumo的配置文件
输出：和sumo的生成文件一样
编程语言：C++
2、用法描述
上图为sumo-gui的初始化界面
其实在windows下界面很常见。这里主要说一下主要用到的功能：time，点击这个按钮可以实现在秒和时分秒之间的显示转换。delay，可以设置延迟，能够放缓仿真的运行，相当于视频播放器的放慢和快进功能，车辆的仿真不受影响，就是仿真演示速度快了。默认的状态是delay为0，即不放慢。有可能仿真很快，你还没看到车辆就结束了，这时你只要调大delay值就能看到详细过程。【在运行过程中，我发现将delay设置为1000，那么仿真就是和真实时间是同步的，即每秒更新一次】
操作：鼠标右键和活动轮进行缩放，左键进行平移。
3、与视图的交互
3.1基本的导航
一旦一个网络被加载那么就可以进行交互。鼠标右键和活动轮进行缩放，左键进行平移。或者按住ctrl或者shift键，滑动滑动轮。缩放集中在屏幕的中心或光标位置上。
您还可以控制网络的哪个部分是可见的，通过直接设置的网络坐标，这将是在屏幕的中心随着变焦。
3.2键盘快捷键
有很多菜单的选项可以通过快捷键实现：
ctrl-左击：光标下的对象的选择状态
箭头键：移动视口
ctrl+箭头键：少量移动视口
PageUp/PageDown：大量上下移动窗口
shift+ PageUp/PageDown：左右大幅度移动窗口
+/-:放大/缩小
Home键：将加载路网中心对齐
ctrl+v：打开设置窗口
3.3改变模拟的外观/可视化
通过ctrl+v或者打开第三行从右数第二个七彩盘的按钮，调用出设置界面。
除了默认的显示，你可以修改一些显示，比如背景颜色、车辆和道路的形状或者兴趣点的可视化。可以保存或者删除相应的设置。

除了颜色外，还能够设置车道边界、连接贴花、钢轨、道路的名字、内部道路的名字和隐藏宏连接器。同上，名字的显示也是固定大小。
3.4在sumo-gui中使用贴花（decals）
打开设置页面，选择background就会看到相应的设置。
可以看到上图的列表中有： picture file, center x, center y, width, height, 和 rotation。现在，现在，如果你点击第一行的picture file，你应该能够输入一个图像文件的完整路径。确保路径正确，然后按下enter键确认。随后，将会在视口中显示响应的文件，正如下图所示：
上图是在路网的基础上添加了一张坐标图的图片，如下如所示：
目前，SUMO_GUI可以加载gif和bmp图片【测试其他类型图片也可以，这句话针对的老版本，忽略它】。要注意，图片的长长宽应该为2的幂次方。这意味着这个图片必须是2,4,8,16,32,64，…..像素。这是由于OpenGL中的限制【这个不清楚】。自从sumo的0.11.0版本，sumo-gui自动调整图片值向邻近的2的幂次方值，并且支持的格式也比较多。包括pcx,ico和tag，png，JPG，tif。关于更多的格式问题，查看FOX的更新状况。【因为sumo的GUI都是基于FOX实现的，因此需要FOX的支持】。
现在，你可以放置/缩放/旋转图片，通过属性：center X，center Y，width，heigh和rotation。当设置relation为1时，position和size的值将会采用屏幕的像素值，并不是网络相关的值。再对齐后你可以保存相应的贴花。你也可以自己定义：
<decalfilename="background.gif" centerX="550.00"centerY="1530.00" width="64.00" height="64.00"rotation="0.00"/>
以下的参数选项：
| ttribute Name | Value Type | Description |
| filename | path (string) | picture file, the full name of the background image 贴花的完全路径。 |
| centerX | float | center x, the x-position of the center of the image in network coordinates (in meters)x轴的中心 |
| centerY | float | center y, the y-position of the center of the image in network coordinates (in meters)y轴的中心 |
| width | float | The width of the image in network coordinates (in meters) 在网络坐标中的宽度，单位米 |
| height | float | The height of the image in network coordinates (in meters) 在网络坐标中的高度，单位米 |
| rotation | float | The angle of the image in degrees 图片的角度 |
| layer | float | The layer at which the image in drawn in meters over ground 在地面绘制的图像的图层 |
| screenRelative | bool | relative, whether the position and size are pixel coordinates relative to the screen rather then the network coordinates 根据屏幕像素确定位置。 |
| centerZ | float | The z-position of the center of the object in network coordinates (in meters), only used in 3D visualization instead of layer 只适用于3D可视化。z轴方向的中心位置。 |
| tilt | float | The tilt angle of the object, only used in 3D visualization 物体的倾斜角度 |
| roll | float | The roll angle of the object, only used in 3D visualization 物体的滚动角度 |
有关贴花的跟多内容，可以参考：Configuration Files
3.4.1有关贴花（decals）的问题
是不是贴花的大小必须符合net的大小？
不需要，贴花必须手动调整。它可以覆盖任何区域。
3.5影响模拟
目前，你仅仅可以进行少量的交互，看完下面的内容就不会这样了！开启新的内容吧。
3.5.1切换交通灯
右键点击红绿信号灯的颜色条，弹出菜单包含很多信息内容，这个特殊的程序off总是可用的，可以用来切换到一个优先权交叉口。【就是右键有一个off功能】
3.5.2关闭或者打开道路或者车道
右键，也有相应的关闭车道或者关闭道路的选项。同样，也可以打开。
3.5.3计划的作用
将来会有更多的交互会实现：
l 动态的修改仿真选项
l 增加交通
l 改变车辆或车辆类型参数
l 测试Traci函数调用
4、理解你所看到的
4.1道路优先级
在每条路的结尾，都会是个节点，交点处有一个颜色条（信号灯）表明了道路的优先行驶权。不同的颜色有不同的定义：
注意：【没看懂】
如果一辆汽车在模拟制动，相应的限制车辆【不知道翻译是否准确，应该就是妨碍的车辆】也会采取响应的步骤：
设置响应的颜色
右键单击“制动车辆”，然后单击“选择敌人”
The foe vehicles will then be color withthe selection color (typically blue).
5、选择对象
SUMO-GUI允许net文件的任何元素包括道路、车道和节点，能够保存到单独的文件中用于后续处理。通过右键，会有一个“Add To Select”的选项。
这些选择的属性，能够被保存或者加载。从“编辑菜单”中的“编辑选择Edit Chosen”对话框中看。点开以后就能看到你选择过的列表。
6、配置文件
sumo-gui使用和sumo相同的配置文件。可以通过—sumo–help查看相应的选项，或者你可以通过sumo –save—template <file> --save-commented来保存。选项gui-settings-file专门针对sumo-gui。它允许你加载以前用过的配置文件。获取gui-setting文件的最简单的方法就是通过界面设置保存。
注意，gui-setting文件保存的只有视口、延迟和贴花的相关信息。你可以手动编辑。相关的使用示例：
example.sumocfg
<configuration>
<net-file value="yournetwork.net.xml"/>
<gui-settings-file value="gui-settings.cfg"/>
</configuration>gui-settings.cfg
<viewsettings>
<scheme name="...
...
</scheme>
<viewport zoom="200" x="100" y="-100"/>
<delay value="42"/>
<decal filename="background.gif" centerX="550.00" centerY="1530.00" width="64.00" height="64.00" rota tion="0.00"/>
<breakpoints-file value="breakpoints.txt"/>
</viewsettings>关于断点文件（breakpoint）可以通过Edit->Edit Breakpoint->save生成。
你可能通过窗口加载配置文件，或者通过命令行sumo –c example.sumocfg。
并且会有专门的验证文件：sumoConfiguration.xsd。
当然你也可以使用自己提前定义好的验证文件（但是不建议这么做）：
<viewsettings>
<scheme name="real world/>
</viewsettings>
7、多视口
点击窗口的多视口按钮，可以生成新的窗口。可以通过window->相应的窗口编号进行操作。

这部分翻译的比较粗糙，因为好多细节需要截图，并且都是一些基本操作的问题。
