<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>An intersection is where two or more roadways meet. Intersections can be controlled by lights or signs or may be uncontrolled. This is a point dataset that contains the names of the intersecting streets, number of streets that meet at the intersection, and control types at the intersection. Point features in this dataset are defined as nodes, and the Node_Type field helps distinguish the complexity of the intersection. </SPAN></P><P><SPAN>There are two ID fields in this dataset: </SPAN></P><P><SPAN STYLE="font-weight:bold;">Node_ID: </SPAN><SPAN>This is the unique identifier for each point feature in the Intersections dataset </SPAN></P><P><SPAN STYLE="font-weight:bold;">Intersection_ID: </SPAN><SPAN>This is the identifier for each intersection in Strathcona County. It is unique to the intersection but may not be unique to the individual point (node). Some major intersections will contain multiple nodes of varying Node_Type, and these nodes will have the same Intersection_ID. </SPAN></P><P><SPAN>The current Strathcona County street network is a hybrid model between a single-line street network (SLSN) and cartographic representation. This hybrid street network model means major intersections contain multiple nodes. In these cases, a point called a “Supernode” (Node_Type) has been created to represent the entire intersection. “Phantom Nodes” are points that represent an intersection of two or more roads but isn’t the main point for the entire intersection. Once migrated to a SLSN, “Phantom Nodes” will be removed and will be fully replaced by the “Supernode” to represent the intersection.</SPAN></P></DIV></DIV></DIV> |
