3、。图1.3.1 线层连通性检查二、添加路网属性路网属性包括：通行能力、自由流速度、道路名称、交通量、饱和度、自由 流时间（Length/速度*3.6）。在此路网中，自由流速度取值如下：快速路：80km/h；快速路辅路:40km/h；匝道：40km/h；主干路：60km/h； 次干路50km/h；支路40km/h。打开路网层数据表，点击【Dataview】一【Modify Table】添加属性字段。三、小区型心点和连杆的建立1、生成小区型心点在小区图层，使用【Tools】一【Export，打开对话框，进行如图3.1.1所 示的选择，将其保存为“Centroid”的地理文件。图3.1.1 导出型心

4、对话框打开【Map Layers，通过【Add Layer，添加型心点“Centroid”图层， 通过调整其风格，得到了如图3.1.2的小区型心点。2、创建连杆添加索引字段：在路网节点图层，添加“index”的字段。在小区层，点击Tools】一【Map Editing】一【Connect】，打开设置对话框，进行如图3.2.1和图3.2.2的设置。Connect (Layer: area )XOKCancelReset图3.2.1 连接基本设置图3.2.2 连接填充设置点击OK后，生成连杆图。自动生成的连杆图是需要进行修改，使用线地理编辑工具可以进行添加、删除等操作。修改后的连杆图如图3.2.3

5、所示。图3.2.3型心连杆图3、填充连杆属性打开路网层数据表，使用条件选择“ftime=null”，创建“连杆”选择集。将通行能力和自由流时间分别填充为“999999”和“0.001”。具体设置如图3.3.1所示。图3.3.1 连杆属性数据填充四、OD反推1、建立节点层型心点选择集打开节点层数据表，使用条件“indexnull”，建立型心点节点选择 集 “Centroid”。2、创建虚拟网络及网络设置在路网层，点击【Networks/Paths】一【Create，填出一下对话框，进行 如图4.2.1的设置，创建网络“”。点击【Networks/Paths】一【Settings】，进行如图4.2
