Project Goal
As transit systems become multi-modal, so must their system maps.
Address multi-modal system maps
Understand rider views on system maps
Create a design guide for multi-modal, schematic maps
Overview
Take 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 users
Commuters
Frequency
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

Lit Review
Alasdair CainImportance of effective map design
Not knowing/understanding bus maps contributes to non-ridership
User Insights & PerceptionSkewed distances
Unclear maps
User perception of space
Interviews/Case Studies
Cities with unique transit mapsBoston
Chicago
InterviewedMap designer
Agency who dictated the design/elements/criteria
Boston (MBTA)
Key Bus Route Rules:
Run 7 days/week
15 min headway during peak hours
Easily connects to rail system
Reach underserviced neighborhoods
Figure Source : MBTA
Chicago (CTA)
Bus routes with consistent service
Categorize attractionsWhere people want to go
Places that can accommodate a lot of people
Hotels with a capacity threshold

Methodology
On-board MARTA rail survey of transit usersRail-only users
Bus and rail users
Conducted April 30-May 4, 2012
Randomly selected participants in all stations
Asked ridership, map-based, demographic questions
356 Completed surveys
About the Survey Participants
5+ times times per week
Several times per week
About once per week 2-3 times per month 1 time or less per month

No frequency criteria
Aimed at commuters
Based on new attractions list
Not all 30 minute headways are included, only those reaching destinations
Most frequent MARTA map
Frequencies 12-20 minutes

Potential future bus ridership
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?
Results:
Frequent Service: 56%
Popular Destinations: 35%
Unsure: 10%

Bus Ridership
Question:
If one of these maps replaced the current MARTA overall map, would you ride the bus more?
Results:
Yes: 42 %
No: 49%

Summary & Conclusions
Riders found the maps useful
Frequency is important to riders
These maps have the potential for some bus ridership increases
