Coding Transit Itineraries

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
