Other important features of SATURN include:

• Fully interactive analysis of results, including on-line help files
• Estimates of fuel consumption and (in a highly experimental form) pollutant emissions.
• Optimum green splits for traffic signals
• Traffic signal co-ordination modelled
• Lane structure of intersections and choice of lane modelled
• The growth and decay of queues modelled quasi - dynamically
• Facilities to “skim”, e.g., inter-zonal time matrices
• Bus routes, bus-only roads and bus-only lanes included explicitly
• Both left-hand and right-hand drive accepted
• Special features of Australian and New Zealand rules of the road have been incorporated
• Selected link analysis
• Multiple User Class Assignment differentiating between, e.g., cars, taxis, HGV’s, etc.
• Full analysis of O-D routes generated by the assignment
• Network and trip matrix cordoning for sub-areas.
• A SATURN to URECA interface module (SURI) to assist in the economic evaluation of schemes within the UK.
• Facilities to both “dump” SATURN data into ascii files for input into, e.g., spreadsheets or other suites of transport programs and equally to re-input data files from these external procedures.
