2. Overview
• Background to the research
– Case study: the London 2012 Olympics and Paralympics
– Four-wave longitudinal panel survey
– Application of a theoretical model - The Transtheoretical Model (TTM)
• Key findings discussed
– Substantial degree of behaviour change occurred
during the Games (54% made at least one change)
– Some changes were sustained post-Games but these
were limited in the longer-term
– Greater understanding of the underlying factors
affecting change in disruptive contexts, and the
distinctions between different types of change

3. London 2012
• The Olympics – “The greatest show on Earth”
– ‘Major-event’ placing significant pressures on host city
– Up to 800,000 extra journeys on busiest day during London
2012 (Sumner, 2012)
• Great deal of planning to keep system moving
…but it can go wrong – Atlanta 1996
• Travel Demand Management was a key part of the London
preparations
− Behaviour change to complement
infrastructural improvements

5. London 2012
• Overall performance reported as positive
• Increased pressure on system but it still coped well
– e.g. 28% increase in underground journeys on same time in 2011
(TfL, 2012, p.162)
• Examples of isolated disruptions but wider system not
compromised:
6. Panel Survey
• Collaboration between the Institute for Transport Studies and TfL
– TfL commissioned 3-wave panel survey (carried out by AECOM)
– Wave 4 survey conducted by ITS in partnership with TfL
• Examined commute, business travel and non-work journeys
before, during and after the Games
7. The Transtheoretical Model (TTM)
• Developed by Prochaska and DiClemente in the late 1970s
• Originated in the health behaviour field but has been used in the
study of travel behaviour – however it is used here in an
exploratory role
• Used to study behaviour at the individual level, focusing on the
psychological factors that can influence change
• Sees change as a process that an individual progresses through
as they make a change to behaviour

10. What happened during the Games?
• Significant amount of change to commute journeys
– 54% of people made at least one change to their commute
– 25% made more than one change
• More changes for those with a greater preparedness to change
11. Reducing and Re-timing Journeys
• Reducing (31%) or re-timing (25%) journeys most common
• Reducing more likely in those with less preparedness to change
12. Sustaining Changes Post-Games
Short-term (Wave 3):
• 6% of the sample sustained their changes after the Games
• Working from home (WFH) continued at the Games-time level
• Analysis of socio-demographics showed there were no statistical
differences between those who sustained and those who did not
Long-term (Wave 4):
• Levels of WFH have continued to be maintained
• Other changes have not generally been sustained (e.g. only a
very small proportion continuing to sustain changes in mode)
13. Value of the TTM
• The processes of change helped to highlight the apparent
distinctions between types of change
• Self-efficacy particularly important for changing modes

14. Two-step Cluster Analysis
• However, the TTM did not reflect people’s ability to adapt their
travel behaviour over a short-term period
• A two-step cluster analysis was conducted to explore
inconsistencies shown in the TTM
• 8 Processes of change and 7 self-efficacy items tested
• Produced four clusters that did not match to the theoretical
expectations of the TTM

17. Conclusions
• As a catalyst for change, the Games was highly effective but
these changes were not sustained in the long-term
– Many people in the sample showed a flexibility to adapt their behaviour in the
short-term
• The TTM provided some insights but the lack of fit of the data to
the model raises questions about its applicability to the transport
disruption context
• The clusters however showed the value of the processes of
change and self-efficacy constructs
• These may help to identify likelihood of people making a particular
change, and also emphasises the apparent distinctions between
the types of change
