Travel blending® is an individualised marketing campaign implemented
by Steer Davies Gleave consultancy. Travel Blending® has been implemented
in Sydney and Adelaide in Australia, Leeds and Nottingham in the UK and
San Diego in Chile. The Australian examples are presented here.
"The Travel Blending® Program was initially developed as part
of a major public initiative called 'Clean Air 2000' which aims to reduce
pollution caused by car travel in Sydney prior to the year 2000 Olympics.
After the pilot study had been completed in Sydney, the Department
of Transport in South Australia (TransportSA) initiated a trial which
took place in Adelaide" (Rose and Ampt, 2001). Travel Blending®
in Adelaide is known as 'TravelSmart' Adelaide. As an individualised marketing
campaign, Travel Blending® emphasises the "How to rather than
[the]
Should do" (Rose and Ampt, 2001).
Travel Blending® consists of two one week travel diaries completed
by all members of participating households. So far individual participants
have been recruited through the workplace; the individual then co-opts
the rest of their household. The first travel diary allows:
the amount of travel to be quantified
the pollution generated to be calculated
consideration of household interactions which result in travel
generation of targeted suggestions about how to reduce car use.
The second diary:
identifies change in travel behaviour
facilitates feedback to participants
monitors the impact of Travel Blending®
Travel diaries record "all travel outside the home with details
obtained of destination, place and purpose, start and end time of each
trip, travel mode and for car driver trips, the odometer reading at the
start and end of the trip" (Rose and Ampt, 2001). The diaries cover
seven days as week day and weekend journeys can be very different; people
may be more able to travel blend at the weekend than during the week,
or vice versa. It was found that people did complete the full seven day
diaries; possibly because they included a built in reminder system (Rose
and Ampt, 2001).
Travel Blending® does not merely promote replacing motor vehicle
travel with other modes or means of communication, it encourages "thinking
about activities and travel in advance (i.e. in what order can activities
be done, who should do them, where should they be done etc.), and then
blending modes (i.e. sometimes car, sometimes walk, sometimes public transport
etc.), or blending activities (i.e. doing as many thins as possible in
the same place, or on the same journey [i.e. trip chaining]), or finally
blending over time (i.e. making small sustainable changes over time on
a weekly or fortnightly basis)" (rose and Ampt, 2001). The key message
is "to blend travel choices in a manageable but sustainable way to
reduce motor vehicle use [whilst] allowing people to participate
in the same activities that they currently undertake" (Rose and Ampt,
2001).
Further information regarding the detailed design of Travel Blending®
can be found in rose and Ampt (2001).
Impacts on demand
Rose and Ampt (2001) report details of the Sydney pilot study in qualitative
terms due to the small sample size, and the Adelaide study in quantitative
terms.
Sydney
One individual who previously drove to the [train] station every
day, started to catch the bus one day per week. This represents a 12
km reduction in distance travelled per week, and two less cold starts.
The individual also reported that the change was sustainable in the
long term.
One individual who exhibited no change between diary one and diary
two organised a group of friends travelling to the countryside to travel
in two vehicles instead of three. This saved 600km of motor vehicle
travel.
One individual increased walking and ride sharing trips
The above households changed their travel patterns as a result of Travel
Blending®. Two others made fairly dramatic changes because one of
their vehicles was off the road. Other participants had plans to change
in the longer term, including:
Occasionally cycling to a friends' instead of being escorted by car,
by her mother
Organising a car pool for children's' Saturday morning sport
Travelling to work by bus one day per week
Considering access to public transport when moving house in the near
future, so that the household can 'survive' with one rather than two
cars.
Adelaide
Travel Behaviour Change Amongst Adelaide Participants indicates the changes
in car use as a result of Travel Blending®. The results of a Z test
to test the hypothesis that the means are equal for diary one and diary
two, against the alternative hypothesis that the mean for diary two is
less than that for diary one are also included.
*Significant at a 5% significance level, critical Z value = -1.64.

Rose and Ampt (2001) have produced aggregate results for the population
as a whole by including non-participants in the analysis. This is done
by assuming "that each person who refused to participate in rounds
one and two travelled in the same way as the average for all persons in
diary one (i.e. before they had received feedback) in both rounds, and
that any person who participated in dairy one and not diary two was assumed
to have made no change between the two diaries" (rose and Ampt, 2001).

Impacts on supply
Travel Blending® has had no impacts on either the supply of road space
or public transport infrastructure.
Other impacts
Changes in participants' opinions and attitudes are reported for the Sydney
study (Rose and Ampt, 2001). These are:
"Unanimous agreement that the Travel Blending® Program resulted
in increased awareness of the use of the motor vehicle and its associated
environmental consequences for people of all ages. The tailored feedback
was given as the major reason for this."
"One individual who did not reduce her car travel said
that "I started valuing my trips in the car". This respondent
came to appreciate the role the car played "as an important tool
to communicate" and for the access it provided for speciality shopping
and leisure activities."
Another "participant said "I used to consider convenience
and cost when making travel decisions now I consider three things: convenience,
cost and environment."

Travel Smart®
Context
Travel Smart® is a registered trademark of the Western Australian
Department of Transport (TransportWA), used as a branding for voluntary
travel behaviour change programmes. Travel Smart® informs and motivates
people to use alternative modes to the car, including ride
sharing and alternatives to travel (e.g. teleaccess). Like Travel
Blending®, Travel Smart® does not constrain mobility. Travel Smart®
as a brand encompasses a variety of attitudinal and behaviour change measures,
including individualised marketing.
The Travel Smart® individualised marketing was developed by SOCIALDATA
under the name Indimark. Travel Smart® individualised marketing starts
by identifying individuals who are prepared to think about reducing their
car use through telephone surveys. Those completely resistant to the idea
do not receive any further communication. Those who already use alternatives
a lot receive some form of reward, which is found to increase use said
modes further. Those who are prepared to think about reducing their car
use and participate provide information about their journeys and receive
targeted suggestions to reduce their car use. This is done through the
post or a home visit where appropriate. (Brög and Schädler,
1999).
A pilot study was undertaken in South Perth in 1997, with approximately
400 randomly selected households. The pilot comprised a benchmark survey
in August 1997, intervention in September/October 1997 and an evaluation
survey in November 1997. A second and third evaluation survey were undertaken
in September 1998 and February 2000 respectively.
A large scale application occurred between February and June 2000, but
the full evaluation has not be obtained to date. Monitoring of the large
scale application was also undertaken using the electronic bus ticketing
system in the area subject to individualised marketing.

The farebox monitoring undertaken with the large scale application revealed
a 27% increase in bus patronage between the period March to June 1999
and the same period in 2000. Over the wider network, there was a 1.5%
increase in patronage, thus the net increase resulting from the Travel
Smart® individualised marketing is 25%.
Impacts on supply
The implementation of individualised marketing through Travel Smart®
does not affect the supply of road space or public transport infrastructure.
It is possible that supply of public transport services may increase in
response to demand.
Other impacts
The Travel Smart® analysis notes a number of cross cutting benefits.
Many of these fall within the contribution to objectives below, but additionally,
there are preventative health outcome due to increased levels of physical
activity.

Indimark in Europe
Context
Brög and Schädler (1999) report Indimark in Europe, which takes
the same form as that developed for Travel Smart® in Australia, described
above. Following the Australian success, the 'Switching to Public Transport'
demonstration project was initiated in Europe by the International Association
of Public Transport (UITP). Indimark was applied with the specific aim
of increasing public transport patronage, and has since been adopted by
a number of operators as part of their marketing strategy. All applications
in Europe have included upwards of 2000 participants, the largest being
in Leipzig, where there were 75,452 participants.
Impact on demand
Like the Travel Smart® results, those in Europe indicate that changes
are sustained over two years. Even where there is a slight reversal in
changes in travel behaviour, there is still less car use and more public
transport use two years on than before intervention.

Impact on supply
Again, implementation of individualised marketing does not change the
supply of road space or public transport. However, there may be increases
in public transport supply resulting from increases in demand, especially
as Indimark in Europe has been implemented to increase patronage.
Other impacts
Indimark has resulted in an improved image of public transport amongst
the target group. Perceptions have also improved amongst a control group,
but by a much smaller degree.
Source: (Brög and Schädler, 1999).
Participants who received a 'test ticket' (a free ticket that could be
used for trial public transport use) reported improved perceptions of
public transport and increased intentions to use public transport. However,
a trial of test tickets in one German city, without prior contact and
dialogue indicates that experience alone does not change behaviour. The
dialogue is essential.
Source: (Brög and Schädler, 1999).
Additionally, one Austrian city public transport operator sent out conventional,
untargeted information packages to one group, in addition to the Indimark
group. The results suggest that conventional information has little impact
on public transport patronage, but that Indimark does have an impact.

Gaps and weaknesses The primary weakness in the evidence presented stems from individualised
marketing to reduce car use being a recent development. Consequently,
there is a scarcity of evidence.
