3. THE SELF-ORGANIZED LANDMARK The self-organizing bus stop serves as an electronic concierge and
digital gateway to the offerings of both its own neighborhood
and the transportation system at large. Through appropriate use of
digital technology, we can turn bus stops into sensual,
engaging, memorable landmarks that have varied and distinctive
character, and that respond vividly to the unique features of
their contexts and communities in multiple ways, at multiple scales,
and in multiple time frames.
4. Introduction
The horse-drawn omnibus was introduced to Paris in the 19th cen-
tury, and the fuel-powered bus in 1906. Today, smart urban
mobility systems – making use of advanced sensing, computing,
and networking technologies – promise a similarly profound
revolution in transportation.
CONCEPT The bus was one of the most successful inventions in the history of
transportation, and it has served cities effectively for a century.
Nowadays, we face new design challenges, and new technologies
can help to meet them.
This exhibit, a concept station – the result of two-year collaboration
between MIT and RATP on Smart mobility – explores their
emerging potential: the bus stop, a self-organizing landmark.
5. In 1662, Blaise Pascal initiated the world’s first public transportation
system – consisting of “five-penny” horse-drawn carriages. He
also invented a calculator. Smart urban mobility systems belong to
this rich genealogy, and draw these two themes of Pascal’s
imagination together in a new way.
6. Rethinking the bus system
Urban mobility systems traditionally combine high-speed, high-
volume, point-to-point transportation with more flexible but
slower and lower-volume modalities – walking, bicycling, taking
a taxi, and driving.
Ubiquitous access to information through mobile wireless devices
shifts the balance toward individual mobility. It allows high-
volume transportation to become more flexible and responsive,
and consequently, the traditional distinction between collective and
individual transportation blurs.
Transportation systems can become more responsive to changing
demands, users can make better transportation decisions, and
vehicles can provide important new services.
The Smart Mobility project demonstrates the application of these
concepts to the Paris bus system. Further details can be found

7. Landmark interactive bus stops
The bus stops of smart urban mobility systems function as power-
ful urban landmarks, particularly in areas of the city that need
strengthening of identity and focus.
They can take advantage of twenty-first century digital display tech
nology, in the same way that Guimard took advantage of the
industrial technology of his time in his designs for Metro stations.
Electronic, networked bus stops can serve as entry and orientation
points for transportation systems and neighborhoods,
supporting bus line agents – neighborhood concierges – who provide
guidance and advice, both in person and online.
The transportation system can broaden its role from that of a pro-
vider of physical mobility to that of a comprehensive source of
efficient access to the varied and far-flung resources and attractions
of the city.
This exhibit features a working prototype of a landmark interactive
bus stop constructed from inexpensive materials. It does not
have a standardized form, but takes advantage of new design and
fabrication technology to adapt to different contexts and needs.
8. The double sided bus stop, interacting and engaging
Facing the city, the exterior of the prototype bus stop has a
smart skin that senses and responds to the presence of
pedestrians – thus creating a playful, engaging art work. It can
be programmed with a wide range of continu-ally changing
content as appropriate to particular localities and seasons.
This particular prototype employs LEDs embedded in silicone
tiles and video sensing for the smart skin.
Facing the waiting passengers, the interior provides displays
and interaction screens for way-finding and schedule
information, news, local businesses and points of interest, and
local community networking services.
9. Reconfiguring buses
By embedding electronic intelligence, buses can become more
flexible, so that they wiggle themselves through the streets
in more agile fashion. They can provide effective service to areas
with narrow streets, winding roads, and complex topography.
Use of flexible, versatile buses help to better manage interchanges
among different transportation modes, thus making travel
more efficient and less confusing; the “snake” bus can penetrate
more areas of the city, and the “worm” bus can go underground.
Below street level, in addition, the “worm” bus can enter efficient
multimodal interchanges where pedestrians can access multiple
transportation systems – private cars, shared cars, bicycles,
and other public transportation systems. And versatile buses can
combine passenger transport and cargo transportation during
off peak hours, especially during the night. Furthermore, the
“stadium” bus can provide both a window on the city and a place
for bicycle storage.
Through use of networking, display, and interaction technologies,
buses can now provide many additional services, extending
their role far beyond transportation. They can become mobile
network nodes, so that passengers are connected for guidance,
entertainment, mobile work, and tourism. Both interior and
exterior surfaces can carry information displays. Buses can
increasingly become work, entertainment, and social spaces on
wheels, while their exteriors serve as dynamically programmed
urban information displays.
10. The bus stop is conceived of as one, continuously modulated
ARCHITECTURE
surface that responds to local conditions and functional
requirements by gradually varying shapes, curvatures, and
densities. The structure is composed of non-repetitive,
CAD/CAM-cut ribs that vary in shape and density as required
by structural and other roles. Parametric design allows us
to create bus stops whose shapes are physically adapt to the
surroundings, while maintaining a common underlying identity.
13. The bus stop form was parametrically modeled, and organized to
support CAD/CAM fabrication. This meant that bus stops
did not need to be standardized and repetitive – expressing a
typically modernist one-size-fits-all design philosophy – but
could potentially be mass-customized to fit particular urban contexts
and opportunities and patterns of transportation demand.
14. Programmable LEDs in architecture have taken the form of urban
scale screens that simply obliterate traditional architectural
effects. We overcame this limitation by using flexible modular
tiles consisting of coarsely spaced LEDs embedded in cast
silicone, which allows them to conform to the parametric struc-
ture of the bus stop.

16. In this translucent medium, pixels can flare not only in intensity but
also in size, while the outer surface texture creates specular
gloss and self-shading effects as well. In addition to providing water-
proofing, the calibrated translucency allows an interplay of
natural and artificial light.
PROGRAMMABLE SURFACE
17.
18. The outside of the bus stop, facing the city, mirrors the internal
urban garden. The skin playfully interacts with people and
engages them by reacting to their behavior. Sensors and cameras
also monitor external environmental activities such as traffic,
air and acoustic pollution, and these elements are synthesized with
the flow of digital communication to determine the urban
garden’s wellbeing.
SENSORS

20. The bus stop is designed to be a self-organizing landmark, capable
of blending chameleon-like into the neighborhood it is placed in.
TWO FACES
21. Reflecting local information, communication, and everyday activity,
its façade elegantly changes over time to gain the markings of a
member of the community.
22. The interior of the bus stop, used primarily by passengers, contains
INSIDE
two screens dedicated to separate purposes. The first screen
houses a location-centric communication and content platform.
The second screen gives access to transportation information.
23.
24. The bus stop is also an open platform, allowing local artists to create
OUTSIDE
new interactions for the outside. The artist may chose to insert
elements into the garden, or if they wish, to replace the entire vista
with some fantastic landscape from their imagination.
25.
26. The second screen is a mean for use by the transportation agency
to communicate information about services, products, service
disruptions, and so on. On this screen, passengers can plan their trip
and download it to their mobile devices. If needed, they can
also start a videoconference with a live transportation agent for help.
INFORMATION
27.
28. All content on this screen is user generated, including entries for
local services, businesses, events, and classifieds. The interface
concept used for this screen is the urban garden, with the trees
serving as interface elements. Each tree represents a topic, and
each leaf a message. The goal of the system is to foster interaction
and communication between the users of the bus stop, and to
allow them to shape the digital form of the bus stop with their own
actions. The exterior, a direct reflection of this interface, thus
reflects the richness, flow, and intensity of communication.
