- More complex
- Rail investments road development
- Industries and villages
- Conditions for living and welfare
- Caused by many individual reasons and decisions
not by strategic planning
3Processes of decisions
- Extreme 1 Rational perspective
- Extreme 2 Wagging the way forward
- Visionary Main problem and future status in
clear picture (Vision Zero) - Planning Defining goals from problems to solve.
Goals define valuations. - Consensus oriented Acceptance through
discussions with parties goals, problems

puppet in a basement.
Consider this! Who should have the puppet?
- 1) He/she fixed the key and that made it possible
to get into the basement. Compensation after
work/Aristoteles - 2) He/she is the strongest of them all and if
he/she dont get the puppet she will start a
fight, which she probably will win. Negotiation
positioning/Hobbes - 3) He/she spotted the puppet first and thats why
she must have it. Practical philosofic
arguments/Locke, Nozick - 4) It means most for he/she, because the
collection will be completed then. Utility
maximization principle - 5) He/she is underprivileged and has no puppet at
all. Maximize-Minimize principle/Rawls

7Goals in transport policy (1)
- The overall goal of transport policy in
accordance with the Swedish Parliaments decision
in 1998 - to ensure a socio-economically efficient
transport system that is sustainable in the long
term for individuals and the business community
throughout the country.
8Goals in transport policy (2)
- This goal is divided into six subsidiary goals
- An accessible transport system The transport
system is to be designed so as to meet the basic
transport needs of individuals and the business
community. - High transport quality The design and function
of the transport system is to permit a high level
of transport quality for individuals and the
business community. - Positive regional development The transport
system should promote a positive regional
development, both by evening out differences in
the potential of various parts of the country to
develop, and by counteracting the drawbacks of
long transport distances.
9Goals in transport policy (3)
- This goal is divided into six subsidiary goals
- Safe traffic The long-term goal for road traffic
safety is for nobody to be killed or seriously
injured as a result of traffic accidents. The
design and operation of the road transport system
should be brought into line with the requirements
that this goal entails. - A good environment The design and performance of
the transport system should be adapted to the
requirements for a good and healthy living
environment for everyone, where natural and
cultural environments are protected against
damage. Good management of land, water, energy
and other natural resources is to be promoted. - A gender-equal road transport system The road
transport system is to be designed to fulfil the
transport needs of both women and men. Women and
men are to be offered an equal opportunity to
influence the creation of the transport system,
its design and management, and their values are
to be equally important.
10Since 1997
- In October 1997 the Swedish Parliment adopted a
Vision Zero approach as a basis for Swedens
long-term road safety objectives.
11Beauty Contest!
- The most effect per invested capital
- killed and seriously injured persons / investing
capital cost (euro) - Priority to maximize number of saved persons for
a given budget. - Effects and impacts have been collected and
documented in a knowledge based document used by
all planning in road sector. - Equivalent for other transport mode system
12Estimate Effect examples
- Speed reduction - (speed after/speed before)4,5.
If speed is reduced from 100 km/h to 90 km/h it
will give about 38 reductions for expected
fatalities. - A pedestrian sidewalk can give somewhere between
40-80 percent reduction, depending on if the
sidewalk is on both sides of the road or on one
side if its completely separated from vehicles
or partly separated. - Steel guard rails and/or removing obstacles from
roadside can reduce the severity of accident
outcome with 15-60.
13Estimate effects example
- Pedestrian crosswalks are estimated to about
20-30 , with island and footpath extension and
fences up to 50. -
- Medians give a reduction for pedestrian with
about 20-25 and for head on collisions almost
100. -
- Improved visibility and guidance, including
illumination is estimated to give an accident
reduction about 20-30. Illumination can even
give a bigger reduction, up to 65, if a black
spot is found where accidents appear in dark
hours. - Important that the situation in the specific
village under investigation is taken into
consideration when estimating the effects.
14Estimate investment costs
- Calculate construction costs per unit of typical
road construction works - Calculate costs for the designed modules
- Determinate costs for maintenance and costs for
individual measures, land aquisation, ..
15 Presentation about the CostBenefit
Analysis for the Road-Safety-Measure project
16CostBenefit Analysis
- Weighing the total expected costs against the
total expected benefits of one or more actions in
order to choose the best or most profitable
option
17HEATCO
- Developing Harmonised European Approaches for
Transport Costing and Project Assessment. - Project in 6 frame programme 2002-2006.
- Project owner European Commission, DGTREN
- Final version report 17 maj 2006.
- Consortium
- IER University of Stuttgart Tyskland, University
of Bath UK, EIT University of Las Palmas Spain,
COWI Denmark, BUTE Hungary, ISIS Italy, Ecoplan
Schweiz, TNO Dutch Nederland, VTI Sweden, SWECO
Norway, ITS Leeds UK, Herry Consult Germany, NTUA
Greece and Sudop Tjeckien.
18- Evaluation methodes of projects with several
countries involved - Evaluation of EU fonds projects
- Harmonizing of assessment with one framework.
(Some countries without consistent method). - Purpose Guidelines based on criterias
socioeconomic efficiency, open and clear studies,
and support from member countries decision
makers.
19Decision criterias
- NPV (net present value) (positiverecommend)
- BCR (benefit cost ratio) (gt0 recommend)
- RNPSS (ratio of NPV and public sector support)
(gt1recommend, valid for priorities with limited
budget) - FYRR (first year rate of return) valid for
decison of optimal opening year for a project.
20- Real changes during project lifetime years
- Factor prices/market prices
- No monetized effects
- Lifetime period
- Risk and uncertainty
- Discounting
- Allocation of effects
- Marginal Cost of Public Funds
21- Values of Time
- Values of risk and accidents
- Noice
- Air pollutions
- Climate gases
- Other specific situations of environmental
aspects - Construction cost
- Planning cost Only costs after decision made
- Land use costs land value, cost for buying
process. - Cost for trafficants during activities
(Trafficant extra cost) Estimate effect and
value as ordinary time value - Maintenance costs
22Accident data
- We assume that reported fatalities are probably
most - accurate. With the figures of fatalities as a
starting point - one could expect the number of severe injured to
be - about 3 times the fatalities and light injured
and damage - only about 8 times the fatalities
23Accident cost in European countries related to
GDP (Gross Domestic Product)
24Consider this!!
- A positive CBA-ratio is an information to the
decision maker that the project is positive for
the society. - The non monetized effects can on the other hand
be positive (better) or negative (worse) for the
society. - How to prioritize between investment package A,
B, C and D?
Non monetized effect better Non monetized effect worse
CBA Positive A C
CBA Negative B D

27MID-BARRIERS / CENTRE GUARD RAILS
- A centre guard rail prevents head-on collisions,
thereby making a rural road of standard width
considerably safer. - Appr. 1000 km in 2004
- Goal 2000 km in 2007
- Test started in 1998
- with 6 projects
- AADT 4000 - 22000
28What purpose have socioeconomic analysis and
calculations had so far, and how should it be
tomorrow?
- Its obvious that decisions divert from results.
This goes for beneficial and non-beneficial
projects! - Rail tunnel in Malmoe (NPV/Clt0)
- Road plans in Stockholm (NPVlt0)
- A number of rail projects (bothnia stretch,
Hallands tunnel) (NPV/C lt 0) - Bypass Sveg (NPV/C 6)
- Russia projects?
29Why is it like that? That decisions divert from
results?
- Building Monument Monument thinking allied with
happy calculations (too low costs and
overindulgence of benefits in relation to facts)
make it easier to get decisions through. (english
channel, big belt bridge, ..) - Distribution of benefits and costs, and different
groups of interests power on decisionmaking. A
concentrated group who gain from a project that
have wide distribution of costs lobbyism have
good chance to success. - Paradigm conflicts Dont believe that
infrastructure improvements have great importance
for socio economic development by summing up the
effects of time, accidents, envronments effects
values. - Unclear what calculations include and exclude
Regionaleconomic effects and distributional
effects. Can a region that are left behind be
helped better?
30How should it be from now on?
- Remember that CBA is one paper for decision and
not a decision. - A well done CBA is a very important paper for
decision. - Old habit thinking can be revealed (more safety
is always better than less??). - Monument building decrease. Public interest more
critical to decisions. - Evaluate difficult effects that are nonmonetized
with the total of excess or deficit. - Consider this for Russia Socioeconomic
evaluation should be made in all studies
(feasibility etc).
31Review of the Multimodal Appraisal System in
Sweden
32Use of CBA in Sweden/Europe
- Swedish transport policy is guided by an overall
goal, to ensure a socio-economically efficient
transport system that is sustainable in the long
term for individuals and the business community
throughout the country
33Goals in transport policy The overall goal of
transport policy is divided into six subsidiary
goals
- Accessible transport system
- High transport quality
- Safe traffic
- Good environment
- Positive regional development
- Gender-equal transport system

46Summary and conclusions
- CBA is a useful method to the long-term planning,
but be useful in some other cases of planning
matters. - CBA is one of many foundations for
decision-making. - CBA doesnt present the whole truth.
- CBA could in some cases be misused by the
decision-makers. - CBA is used more a less for investments only
- Need to extend the use of CBA for other actions.
- Lack of measure / effect correlation for some of
actions.

52Review and Implementation of new Speed Limits
Sweden 2008 2009
incorporated to present speed limits 30 50
70 90 110
53New Speed Limits
- Parliament decision may 2007 Road
Administration, Regional Governments and
Municipalities have the right to decide on speed
limits from 30 to 120 km/h with succession of 10
km/h step. - Government decide in traffic regulation so Road
Administration can implement speed limits 80, 100
and 120 km/h. - The new regulation starts from 2 may 2008.
- General Director of Road Administration decide on
guidelines for the implementation of new speed
limits, December 2007.
54In a long term perspective shall
- a consecutive adjustment of speed limits
towards vision zero and that demand on
accessibility, good environment, positive
regional development and an equal transport
system been taken in consideration. - Governmental Proposition of New Speed Limits
55New Speed Limits Why ???
- Present system from 1971 (1955 urban areas)
- Inconsistency of decisions during that time
period. - Speed limits have not been considered from humans
ability to handle physical violence. - New transport policy goals have been decided.
- From safety- and environmental perspective, is
20-step to big. - Road transport system can be utilized more
efficiently with respect to all transport policy
goals. - Acceptance for new speed limits should increase.
- New road types since 1971.
56How shall this be implemented??
- Road Administration review of roads outside urban
areas (mostly 90 and 110 roads) - Municipalities implement new speed limits within
planned urban areas. - Regional governments adjust local speed limit
decisions and private roads. - Review in close coperation with new long term
plan 2010 2020.
57(When) Time schedule state roads
Phase 1 - National roads Autumn 2008 European road and major other roads
- Motorway 120 km/h Autumn 2008 European road and major other roads
Phase 2 - Other major roads Spring 2009 Secondary roads
Phase 3 Other roads Autumn 2009 Other roads
58Criteria for speed limit decision
- Accessibility road connections important to
keep or preserve higher speed limit, is road
connections important for commuting, extended
local labour market functionality, high share of
long distance transports, rural areas with
longer transports in sparsely populated areas or
high importance for freight transports. - Traffic Safety physical damage violence on
human being - Environment harmonically speed limits, national
Carbondioxide (CO2) goals, local concentrations
of pollutions and noice level. Increased
externalities on a certain road network can be
compensated of reductions on other road network. - Trafficant acceptance Fare, logical, clear and
self explanatory speed limits
59- Consequences
- Reduction of killed persons annually 10 persons
- Carbondioxide (CO2) reduction 10000 ton/year
- Travel time increase with 2 miljon hour/year cars
and buses - Indifferent transport time for heavy lorries.
- Valuable socioeconomic benefits annually 6 MECU
(Milj Euros) - But 700000 ton/year CO2 and 150 saved life
- Just follow the present speed limits
