Counterpart Paths: Example paths, comparison network, and SCPPOD Output

InputData Directory

This network dataset is an example of a network to which paths from other networks (i.e. Networks A and B) can be compared.

Contains two directories:

a) NetworkC
b) NetworkPaths

'NetworkC' Directory

- This network is based upon a subset of the Missouri Department of Transportation (MoDOT) July 2016 road dataset listed in the references.
- NetworkC contains an ESRI .gdb (NetworkCdata.gdb) in which the arcs and nodes for Network C can be found as well as an ArcGIS ND Network Analyst configuration file.
- Featuredataset: NetworkCsub
- Network arcs: NetworkCsub
- Network file: NetworkCsub_ND
- Network junctions: NetworkCsub_ND_Junctions

'NetworkPaths' contains ESRI .gdbs representing:

a) A collection of routes between OD pairs in each network (InputPaths.gdb)

- The densified routes used in the application (densified at 10m): (Net_A_routelines; Net_B_routelines; Net_C_routelines)
- The original routes with original set of vertices (non densified): (Net_A_routes; Net_B_routes; Net_C_routes)

b) The origin and destination points for the paths (ODNodes.gdb)

- These were used to generate the shortest paths for each network, serving as the paths to be compared
- origins: originLocations
- destinations: destinationLocations

'OutputData' Directory

Contains the comparisons of paths to networks:

NetAToB: comparison of paths from network A to network B
NetAToC: comparison of paths from network A to network C
NetBToA: comparison of paths from network B to network A
NetBToC: comparison of paths from network B to network C
NetCToA: comparison of paths from network C to network A
NetCToB: comparison of paths from network C to network B

Inside each directory is a collection of ESRI .gdb which contains the individual paths used in the analysis as input

a) NetworkAPaths.gdb
b) NetworkBPaths.gdb
c) NetworkCPaths.gdb

Inside each directory is a collection of ESRI .gdb which contains the vertices of the individual paths used in the analysis as input

a) NetworkAPathPoints.gdb
b) NetworkBPathPoints.gdb
c) NetworkCPathPoints.gdb

Also included is a collection of ESRI .gdb that represent the original path nodes that could be assigned to the comparison network.
In this case, only nodes that were within 20m of the comparison network could be assigned. Each path node is attributed with the distance to its counterpart node in the comparison.

a) Nodes in Network A paths assigned to Network B (PathANodesAssignedtoNetB.gdb)

b) Nodes in Network A paths assigned to Network C (PathANodesAssignedtoNetC.gdb)

c) Nodes in Network B paths assigned to Network A (PathBNodesAssignedtoNetA.gdb)

d) Nodes in Network B paths assigned to Network C (PathBNodesAssignedtoNetC.gdb)

e) Nodes in Network C paths assigned to Network A (PathCNodesAssignedtoNetA.gdb)

f) Nodes in Network C paths assigned to Network B (PathCNodesAssignedtoNetB.gdb)

Inside each directory is a collection of ESRI .gdb which contain solutions to the SCPPOD with the following naming convention:

a) comparing paths in Network A to Network B SCCPODarcsPathAtoNetB.gdb for arc elements and SCCPODnodesPathAtoNetB.gdb for node elements)
- The naming convention for the node solutions for path id X is ('SN_routeX_X')
- The naming convention for the arc solutions for path id X is ('routX_Rt' for single polyline counterpart path; and
'routeX_Rtsplit' for a polyline representation of the counterpart path based upon the SCPPOD node output).

b) comparing paths in Network A to Network C SCCPODarcsPathAtoNetC.gdb for arc elements and SCCPODnodesPathAtoNetC.gdb for node elements)

c) comparing paths in Network B to Network A SCCPODarcsPathBtoNetA.gdb for arc elements and SCCPODnodesPathBtoNetA.gdb for node elements)

d) comparing paths in Network B to Network C SCCPODarcsPathBtoNetC.gdb for arc elements and SCCPODnodesPathBtoNetC.gdb for node elements)

e) comparing paths in Network C to Network A SCCPODarcsPathCtoNetA.gdb for arc elements and SCCPODnodesPathCtoNetA.gdb for node elements)

f) comparing paths in Network C to Network B SCCPODarcsPathCtoNetB.gdb for arc elements and SCCPODnodesPathCtoNetB.gdb for node elements)

The counterpart paths that were identified were then linked to the full network C to summarize the frequency with with arcs were associated with paths
- Can be found in:
1. PathARepresentationinNetC.gdb
2. PathARepresentationinNetC.gdb

- important attributes:
a) vcntarc: number of paths utilizing arc
b) ptCnt: number of path vertices associated with each arc
c) AvgDist: average distance of path vertices from network arcs
d) MinDist: minimum distance of path vertices from network arcs
e) MaxDist: minimum distance of path vertices from network arcs
