Project Goal
As transit systems become multi-modal, so must their system maps.
Address multi-modal system maps Understand rider views on system mapsCreate a design guide for multi-modal,
schematic maps
OverviewTake a new look at schematic transit mapping
Make it easier for riders to interact with information
Create user-friendly maps including bus system to encourage multi-modal travel according to riders
Examine rider reactions to these maps
Determine methodologies for producing mapsTourist/new usersCommutersFrequency
Project Motivation
Zhan Guo’s Mind the Map
Schematic maps impact traveler decisions
Class projectAffect bus/system
awareness
Objectives
Identify riders who would benefit from multi-modal maps
Examine rider desires for frequency and/or destination maps
Examine potential effects on bus ridership
Develop methodologies for creating rider-specific maps

Methodology
On-board MARTA rail survey of transit usersRail-only usersBus and rail users
Conducted April 30-May 4, 2012Randomly selected participants in all stationsAsked ridership, map-based, demographic
questions356 Completed surveys
About the Survey Participants
5+ times times per week

No frequency criteria
Aimed at commuters
Based on new attractions list
Not all 30 minute headways are included, only those reaching destinations

Frequency vs. Popular Destinations
Question:Is it more important for maps to show the bus routes that reach popular destinations or buses that come often?

Summary & Conclusions
Riders found the maps usefulFrequency is important to ridersThese maps have the potential for some bus
ridership increases
