Create SSC files
Instructions for Use
Based on the network dataset, construct a *. SSC navigation model file based on the relevant attribute field information set. The model data stores the environmental information required for traffic network analysis, providing a data foundation for subsequent traffic network analysis.
Parameter Description
| Parameter Name | Default Value | Parameter Definition | Parameter Type |
|---|---|---|---|
| Network Dataset | Select the data source and dataset where the network data for the SSC model to be constructed is located | DatasetVector | |
| Arc ID | SmEdgeID | The field that uniquely identifies each arc segment in the network dataset. You can choose the field from the line dataset in the network dataset as the identification field. By default, SmEdgeID is used as the arc segment identification field | String |
| Node ID | SmNodeID | The field that uniquely identifies each node in the network dataset. You can select the field from the point dataset in the network dataset as the identification field. By default, the SmNodeID field is used as the node identification field | String |
| Starting Node ID | SmFNode | Identifies the field of the starting node in the network dataset. You can select the field of the line dataset in the network dataset as the identification field. By default, SmFNode is used as the starting node identifier | String |
| Terminating Node ID | SmTNode | Identifies the field of the terminating node in the network dataset. You can choose the field of the line dataset in the network dataset as the identification field. By default, SmTNode is used as the termination node identifier field | String |
| Enable Traffic Rules | false | Whether to enable traffic rules, that is, set whether the network segment is one-way (including forward one-way and reverse one-way) or prohibited from passing, which is disabled by default. After activation, subsequent parameters need to be set | Boolean |
| Traffic Rule Field (Optional) |
Traffic Rule Field. It takes effect when traffic rules are activated | String | |
| Forward single row value (Optional) |
Add the attribute value corresponding to the forward single row value. Multiple fields can be added. It takes effect when traffic rules are activated | String[] | |
| Reverse single row value (Optional) |
Add the attribute value corresponding to the reverse single row value. Multiple fields can be added. It takes effect when traffic rules are activated | String[] | |
| Prohibited passage value (Optional) |
Add the attribute value corresponding to the prohibited passage value. Multiple fields can be added. It takes effect when traffic rules are activated | String[] | |
| Bidirectional traffic value (Optional) |
Add the attribute value corresponding to the bidirectional traffic value. Multiple fields can be added. It takes effect when traffic rules are activated | String[] | |
| Arc segment name | SmEdgeID | Set the name field of the road, which can be used to generate driving guidance | String |
| Arc Weight | SmLength | Used to change the forward/directional weight of the arc segment and set whether the arc segment is an obstacle edge | String |
| Road speed (Optional) |
Set the road speed field, which is not a mandatory field. The road speed is an integer field, where 1 represents the highest road speed, which is 150km/h; 2 represents a speed of 130km/h; 3 represents a speed of 100km/h; The speed represented by 4 is 90km/h; 5 represents a speed of 70km/h; 6 represents a speed of 50km/h; The speed represented by 7 is 30km/h; The speed of other values is uniformly 10km/h | String | |
| Road Grade | Set the road grade field, a required field with a value range of 1-3, where 3 represents the highest road grade, such as highways; 1 represents the lowest road level, such as rural roads | String | |
| Enable steering table | false | Whether to enable prohibited steering table, disabled by default. After activation, subsequent parameters need to be set | Boolean |
| Turn to Dataset (Optional) |
Set an attribute table dataset as turn to data and specify the data source where it is located. It takes effect when the steering meter is activated | DatasetVector | |
| Turning point identifier (Optional) |
The field used to uniquely identify the prohibited turning point. It takes effect when the steering meter is activated | String | |
| Turning start arc identification (Optional) |
Turning at a node always involves two arc segments, namely a start arc segment and a end arc segment. In the selected steering table, select a field as the starting arc field to indicate which arc segment the prohibited turn starts from. It takes effect when the steering meter is activated | String | |
| Turn End Arc Identification (Optional) |
In the selected turn table, select a field as the end arc field to indicate which arc segment is prohibited from turning. It takes effect when the steering meter is activated | String | |
| File Path | The output path and name of the result file, with the file suffix. ssc | String |
