Slide 2
Social network & Ecomobility Widespread among population of
sophisticated nomadic devices such as smart phones: possibility to
be connected to social networks Anytime Anywhere -> Potential to
support ecomobility Information on real time of location of
danger/risky zones identified by drivers belonging to community
members: potential to avoid traffic jams and to optimise the trip
Ridesharing through connections between drivers and travellers
belonging to the same community: potential to decrease the traffic
on the road Timely information given by public transport operators
to the travellers via social networking: potential to decrease
exclusive car use in urban area
Slide 3
[email protected] Nomadic devices: some statistics about
smart phones Smart phone market grew 54.7% year over year (2011)
corresponding to an increase access to sophisticated services such
as internet and geo- localisation Over 300,000 mobile applications
have been developed in the last three years During February 2012,
50 % of US mobile subscribers owned a smartphone
Slide 4
[email protected] Use of mobile phone is growing among
seniors, since 2000, with differences between countries (USA: 65%,
Sweden & Germany: 62%, UK: 44%, France: 39%) The % of people
with a mobile phone is higher for the age group 65-74 years old
than for the age group over 75 years old (Lin & al., 2009)
According to a study in UK, 49 % of seniors feel intimidated by
mobile phone use (Lin & al., 2009) Smartphone audience by age
group For transport smartphone applications, seniors needs and
requirements have also to be taken into account
Slide 5
[email protected] Social networking Definition and issues
Definition of Social Networking: web applications created by
individuals or organisations on a commercially-provided Internet
platform, usually delivered to the user for free or for low fee, in
order to interact with others through a virtual community.
Community self-selecting: individuals apply to join and to link up
with others on a voluntary base with the issues of degree of trust
or reliability of members of a particular virtual community.
Examples supporting sustainable transport Real time information of
traffic event Instant ride-sharing
Slide 6
[email protected] Real time information of traffic event
Information on real time of location of danger/risky zones
identified by community members: potential to avoid traffic jams
and to optimise the trip Several applications available in Europe
and US Members of the community can have the following involvement:
Inform on real time the community manager system about a road event
Qualify the type of road event following the request of the
community manager system Validate if the road event is still
there
Slide 7
[email protected] Community manager system Qualification
of the event by members of the community Members signaling road
event to the community Validation by members if the event is still
there
Slide 8
[email protected] Benefit of social community for
ecomobility and road safety Several danger zones have been
identified by the community and displayed on a map for the benefit
of any members This display allows also to know that 14 members
with an average of 3 stars, meaning highly reliable in their
contribution to the community database, are located in a close
surrounding.
Slide 9
[email protected] Instant ridesharing Smartphone
technology enables dynamic ride- sharing systems that bring
together people with similar itineraries and time schedules to
share rides on short-notice Objective of application: setting easy
and secure ride sharing services to federate these trips between
drivers and travellers
Slide 10
[email protected] Several mobile applications of
ridesharing planned in advance ridesharing instant ridesharing
(automatic updating of ridesharing offers all along drivers routes)
mixing navigation and integrated billing system. Ridesharing
service
Slide 11
[email protected] Limits of social community efficiency
Bottlenecks regarding benefits of social networking to support
ecomobility Reliability of the information circulating inside the
network Number of members participating instantly (issue of supply
& demand for ride sharing, issue of identification of road
event for traffic information) Privacy issue
Slide 12
[email protected] Reliability of the information
Characteristic of Social Networking applications: do require high
and regular maintenance and very disciplined systems: Rating each
member of the community in terms of reliance with the principle of
stars based upon: Comments of the other members Past experience in
the network Remove or at least neutralise negative comments
Slide 13
[email protected] Real time information on traffic event
On the left of the screen: information on the number of members,
their rating with stars and their distance from the driver On the
right of the screen: risky and dangerous zones ahead displayed
every 10 km with number of stars of the members who sent/confirmed
these road events Reliability of the information
Slide 14
[email protected] Real time information on traffic event
-reliability of information sent by the members -number of members
-timing of communicated information Reliability of the information
Example: Risky zone identified by 4 members of the community,
confirmation of the last one 49 minutes ago. This information gives
some elements to the driver in order to evaluate the validity of
the information.
Slide 15
[email protected] Ridesharing -drivers reliability -match
with the preferences of the travellers Question: which criteria to
transmit to the member? Picture, location, phone number. Do you
smoke? Do you talk a lot? . Privacy- Reliability trade off of the
information
Slide 16
[email protected] Issue of privacy Reduction of
acceptability by users due to privacy issues : Location information
Picture Phone number.. Assessment of privacy vary between different
groups in society (Westin 2003): the privacy fundamentalists who
-despite personal advantages- are against the collection and use of
personal data the privacy pragmatists who decide upon their
viewpoint after assessing the benefits and risks the privacy
unconcerned who generally do not mind sharing their
information
Slide 17
[email protected] Motivation for participation to social
network for ecomobility Solidarity: drivers felt valued to
participate to the knowledge of an entire network for road event
identification Appreciation: members felt valued to get stars based
upon their reliability and the trust they give rise to other
Economic: drivers have refunding when offering ridesharing
Slide 18
[email protected] Design of nomadic device: a challenge
As a mobile device carried out everywhere, the design has to match
with a great variability of contexts, including only one hand use
in some cases The users population, age and cultural background is
highly diversified Interaction with the mobile has to be enough
intuitive and user friendly that it did not require any training
Mobile has small size screen and mirror like reflection with
consequences on poor legibility of display Inputs are challenged by
the small size of the buttons and/or the sensitivity (too much or
not enough) of the tactile screen 16% had difficulty reading
something on their phone because the screen was too small 10% had
difficulty entering a lot of text on their phone (Survey in April
26 to May 22, 2011 among a nationally-representative sample of
Americans)

design for mobile phone Evolution of the screen size through the
successive generations of mobile phones. Evolution of mobile phones

Slide 21
[email protected] Conclusion Social Networking is a
developing phenomenon, whose potential, benefits, and pitfalls will
change as technology evolves. Both positive and negative user
comments and experiences shared through Social Networking can
quickly spread. Some first examples showed efficiency in spreading
information on real time about characteristics of the road
network/public transport or ride sharing service. Further research
needed to evaluate bottlenecks linked to privacy (acceptability)
and design (usability) issues This phenomenon should be taken into
consideration for ecomobility support.
