Coding Transit Itineraries
Frank Milthorpe
Transport and Population Data Centre
Objective
With the availability of electronic public transport time data how do you convert this into Emme/2 itineraries ?
Issues
• Full detail vs simplification
• Consistency between base year and future year
• Transparency in the process
• Emme/2 has a number of features which can assist with graphic display
Timetable Plots
• Using module 6.26• Itineraries input with data to
facilitate the timetable plots • Start time (off-set) in UT field• Pattern coded in UT field• Time between stops in US field• Master route pattern for y axis
Route Plots
• Using module 2.13 option 6 (user defined data)
• Required extensive use of module 2.41 (network calculator)
• Separate calculations for nodes and links
Multiple pattern plots
• Similar process to route plots
• Summary data written in customised plot heading
• Could extend to use multiple layers (currently only using single layer).
Observations
• Route plot macro useful for checking itineraries
• Network calculator in conjunction with 2.13 can used to generate “customised” plots
