NetGen

A tool to generate efficient cargo networks (in Transport Fever 2)

The Map class represents a map, to which Town and Industry instances can be added. The class creates a delaunay triangulation network linking all towns and industries, optionally removing edges which cross impassable lines. A network which minimises cost by using empty return journey capacity is generated.

Features

• Uses a custom graph data structure to store directional weight and cargo flow information per edge
• Generates tab separated text output suitable for import into data visualisation softare or futher processing
• Well documented source code

Documentation

The source code contains documentation of the main functions and types.

CargoType and WagonType enumerations represent cargo and wagon types.

Town and Industry classes represent towns and industries.

Initialization

Map is initialized empty and information is then added using the following methods:

• addTown(_) to add a town
• addIndustry(_) to add an industry
• addImpassableLine(_) to add an impassable line

Network Generation

A network can be generated using te following methods:

• triangulateAllLocations() to create the initial triangulation between all towns and industries
• buildNetworkGraph() to build the network graph in which edges crossing impassable lines are removed from the triangulation
• setUniformTownCargoRequirement(_) to set a uniform consumption demand for all towns
• makeAllConnections() to make all connections for cargo required

Reporting network structure

The network structure can be inspected using the following methods:

• printIndustryInfo() to print node id, type and location of all industries
• printTownInfo() to print node id name and location of all towns
• printAllPaths() to print informatino about each path
• printEfficiencyStats() to print statistics about the efficiency of the network
