This document summarizes a study conducted by Turku, Finland and Siemens on the potential impacts of implementing an integrated light rail network in Turku. The study finds that a light rail system could reduce carbon emissions from vehicles by 11% by 2035 by increasing public transportation ridership by 40%. Properties near light rail lines would also increase in value, with estimated total property value increases of 480-850 million euros. The light rail network is identified as an opportunity for Turku to develop a more sustainable transportation system and livable environment.

2. • Turku is an old city, going
back as far as the 13th
century.
• Located between Sweden
and Russia, Finland also
borders the Baltic Sea,
Gulf of Bothnia, and Gulf
of Finland. Finland's area,
at 337,030 square
kilometers (130,127
square miles).

3. • Turku, Finland’s
oldest city and its
former capital, is
dominated by its
winding Aura river,
the reason for its
existence as a port.

4. • The population of Turku was 177 606 in the year
2010, which makes it the fifth largest city in
Finland by population.
• There were roughly 303 500 inhabitants living in
the Turku sub-region in the year 2007, which
makes it the third largest urban area in Finland
after the Greater Helsinki area and Tampere sub-
region.

5. • Turku is the main city in its region as well as
the cultural and economic centre of Western
Finland.
• The city’s profile has changed significantly in
recent decades.
• The city has expanded by building residential
areas around the old city.
• The city was rebuilt according to a grid pattern
of rectangular blocks in which the relatively
broad streets should prevent raging fires.

6. • The city’s most famous attraction near the
mouth of the river is its well-preserved
medieval castle, dating back to the days when
Sweden ruled Finland in the 13th century.

7. • The present physical
structure of the inner
city is strongly
determined by the great
city of 1827 that
destroyed the
predominantly wooden
buildings of the old city
almost completely.
• The rebuilt wooden
houses have been
replaced nowadays.
• Within the grid by
building and blocks of
stone and concrete.

8. • The outer walls are
painted white with stark,
black-framed windows,
while inside is an older
medieval part with
rough stone walls.
• Behind the castle’s thick
stone walls, interlocking
corridors and
courtyards offer hints of
its glory days in the mid-
16th century, when the
castle served as the
sumptuous court of the
Duke of Finland.
Medieval Castle

9. • Turku City Library in
Turku, Finland by
JKMM Architects
• Located at the
historical centre of the
city.
• The new building is
the latest summation to
a complex with the old
library.

10. • European Oak are
widely used in the
interior wall furnishing
and furniture.
• Building structure was
constructed
from concrete cast
on site, which was left
exposed as an significant
part of the interior
design.
• Glass was given a
seminal role both in the
outer architecture and
the interior world.

11. • The major
sources of
greenhouse gas
emissions in the
city.

13. • Downsize vehicle fleets and infrastructure
in the city centre and upgrade vehicles to
zero emission technology
Green logistic
• Encourage P&R, guide drivers to the best
parking places, charge for entry to
congested areas, and car and bike sharing.
Traffic
management
• The gas can be piped for use directly as a
burnable fuel or used to power an
electricity generator.
Biogas
• Enable energy efficiency in new buildings
and renovations
Building control
and management

14. • This 2 project very attractive but need
substantial work and funding.
• These longer term solutions would build on the
immediate opportunities to create a sustainable
transport and energy infrastructure.
1) Light rail transport
2) Smart Grid : Brings together the electricity
and communications infrastructure to help
match supply and demand.

15. • Geothermal/ground heat : Using heat stored in
soil, rock or water systems, transferred to a
water-based heating system using a heat pump.
• Heat machines and chillers : Capture heat that
would otherwise be wasted, either from
cooling equipment or heat production in
boilers or power plants, and use it to warm
water for district heating or other purposes.

16. • Public lighting : Technical and operational
options can cut energy use, including sodium-
vapor lamps instead of mercury, LED
technology and improved control systems.
• Micro combined heat and power (CHP) :small-
scale power generation producing electricity
from heat at low temperatures using a fluid
such as silicon oil instead of water.
• Smart parking: using parking regulation to
encourage lower emissions vehicles and co-
modality.

18. A way to improve air quality and
diminish environmental impact
by reducing CO2 and pollutant
emissions via traffic reduction
and optimization.
Light rail gives also an
opportunity to reshape,
harmonize and develop a city
An opportunity for Turku to take
the path towards a sustainable
transportation system and a
wealthy and livable
environment.
The integrated light rail solution
is the result of both the
implementation of the light rail
and a set of targeted policies
aiming at favouring green
transportation as well as
triggering city development.

19. Trunk bus network will be implemented in
Turku urban region 2011 to 2014, covering
suburban Turku and centres of neighbouring
municipalities
Centres of separate villages function as
intermodal interchanges between public
transport, walking and cycling
Trunk bus lines to villages are defined :
• Skånetrafiken Pendeln a good example
Centres and periphery of the villages .
• Fast and effective public transport lines
serve the centres every day from morning to
night
• Public transport lines can be extended
over the centre to the periphery

21. Edges of central area (e.g. Varissuo-
Littoinen)
• Cycling and public transport should
continue to the edge and be
competitive with car
• Local services reachable by walking
Separate built-up areas (e.g Masku,
Nousiainen, Mynämä
• It should be possible to walk or cycle all
trips within the area all year round
• There should be an attractive cycling and
public transport connection to the centre.
Outside built-up areas
• It should be possible to connect to
public transport by car or bicycle at
the nearest built-up areas.
From the central areas
• Important recreational sites, workplaces
and services should be reachable by cycling or
public transport, possibly depending on the
season
To the central areas
• Transports into the central areas should not congest
the main nodes into the City of Turku or in the
regional road network
• It must be possible to connect to the public
transport at the edges of the congested area

22. Mobility management means promotion of:
• Walking and cycling
• Public transport
• Sustainable car use

24. • It is the cooperation with the city of Turku and
Siemens.
• The study evaluated the effects a light rail
network would have on Turku from an ecological
and economic point of view.
• An integrated light rail solution would reduce
carbon emission by 11 percent by 2035.
• Properties value alongside the network would
increase by an estimated total of 480 to 850
million euro in conservative scenario.

25. • Increase in the use of public transport can
reduce the gas emissions.
• The integrated light rail solution would
increase the number of public transport trips in
Turku by 40 percent before 2035.
• A third of the residents of Turku will live along
the planned light rail system in 2035.

26. • It is estimated that CO2 emissions from vehicle
traffic in Turku will rise by 25 percent,
130,000 tons by 2035.
• Approximately 88 percent of emissions come
from cars and 12 percent from buses.
• The integrated light rail solution would reduce
CO2 from vehicles by 11 percent by year 2035.
• Corresponding to an emission level of 110,000
tons.

27. • The integrated light rail solution would reduce
NOx by an additional 12 percent to about 250
tons in 2035.
• One light rail carriage is equivalent to 40 cars
and two buses.

28. • The study shows that property values will rise
in areas that are within walking distance of the
light rail system
• The price increase is expected to occur in 800
meter buffer zone along the planned light rail
lines.
• The value estimated would rise about 480 to
850 million euros in 2035.
