Significances for ”Upgrading” Nations ü Transport mode change: Towards Air and Road ü Vehicle type change: Single-axle trucks > multi-axle trucks > ü ü ü ü ü articulated trucks, light commercial vehicles. High motor vehicle use but slowing growth, metro / inter-city emphasis. Population change: Age distribution. Network development emphasis: Upgrading existing roads for capacity & safety. Road funding requirements: High. Dominates share of transport demand between modes: logistics / heavier vehicles Political: Regional & community issues, public transport issues Environmental: Vehicle intrusiveness, air quality, noise Social: Travel demand, gender equity Economic: Higher standards for safety and capacity Private sector involvement: consulting, design & construction, maintenance, financing
Level of Standard (The never ending question) Standard to whom, when funding is limited? ü Customer friendly standards Today's customers, right now ü Standards from strategic perspective Tomorrow’s customers considering a sustainable development in all means ü Standard from an economic perspective Minimizing cost now and/or in the long-range - LCC ü Technical standard Usually sophisticated and expensive standards

Anbania continue ü The road sector has a need for minimum 600 Million € yearly to keep the roads in the country up to date and in reasonable condition. ü This corresponds to 5 % of the GDP in Albania or 25 % of the government revenue. Is this realistic?
Value for Money ü Efficiency: Cost of each unit of output or To do the things right ü Effectiveness: Contribution of output to achievement of desired outcome or To do the right Things ü Allocation methods (Upgrade) – Maintenance - on basis of optimised network (strategic) level needs analysis – Improvements – projects selected on basis of economic evaluation allowing for environmental & social issues

20 years ago Sweden started to look for a new long-term road safety strategy • Already one of the safest countries in the world (6. 5 killed/100 000 inhab. ). • Traditional strategy: fighting speeding, drunk driving, promoting safe driving, seat-belts etc. . • More of the same – or?
Vision Zero: a Safe Traffic Concept History On October 9, 1997 the Road Traffic Safety Bill founded on "Vision Zero" was passed by a large majority in the Swedish Parliament. This represents an entirely new way of thinking with respect to road traffic safety. Goal The long term goal is that no-one shall be killed or seriously injured within the Swedish road transport system.
New approach to responsibilities • Historically main responsibility on the road user (blame the victim approach) • Vision Zero suggests a shared responsibility Claes Tingvall 17 Swedish Road Administration
Vision Zero Safety philosophy • The chain of events behind a serious accident can be cut at many places • Inspiration from other areas ( i. e. occupational health and safety) • People make errors, mistakes and misjudgements • There are biomechanical tolerance limits 18 Swedish Road Administration
Vision Zero philosophy Integration and Separation 1. Vulnerable road users should not be exposed to motorised vehicles at speeds exceeding 30 km/h 2. Car occupants should not be exposed to other motorised vehicles at speeds exceeding 50 km/h in 90 degree crossings 3. Car occupants should not be exposed to oncoming traffic (other vehicles of approximately same weight) at speeds exceeding 70 km/h or 50 km/h (if the weights are considerably different) 4. Car occupants should not be exposed to the road side in speeds exceeding 70 km/h or 50 km/h (if road side contains trees or other objects) 19

STA is committed to a safe transport system • Adjustment of road traffic speed – adjusting to road traffic safety standards • More than 1, 000 traffic safety cameras are located on the most dangerous roads • Work on influences: alcohol/drugs, seat belt use, keeping to the speed limit, safety on and near railway tracks, and bicycle helmet use • 4200 km of multi-lane, bidirectional highways • Suicide on roads and rail reduced through preventative measures

Physical Planning and Design 7 -12 4 -7 Years before commencement of construction 2 -4 • Initial Study – describes problems/needs and possible measures to meet the needs. • Feasibility – clear out what solution/corridor that should be chosen to meet the needs, including general environmental assessment and cost/benefit calculation • Detaild Design – shows the alignment including environmental examination. The land that is needed for the construction is made clear and established by law. Appeal can be made to the Government • Procurement –contractors are chosen after open competition
4 Step Principle The Swedish Transport Administration has developed what we call the 4 -step principle. Shortly it means that; 1. Measures that have effect on the demand for transport and the choice of transport mean. 2. Measures that give a more effective use of the existing road network. 3. Improvement of the existing roads. 4. New investment or mayor reconstruction.

Possible Planning Process üTransport Policy adopted by the Parliament (Strategy and Policy of Transport Development in Albania) üLong Term Plan (recurrent) • Government Vision on Infrastructure including Objectives and Financial Frames • Adoption by the Parliament • Government Bodies (MPWT and/or ARA) are given the task of preparing Preliminary Long Term Plans • The Preliminary Plans are referred for Consideration to National, Regional and Local Authorities and Others • With the given opinions in mind The Government make relevant adjustments and adopts the Proposal • After 4 -6 years the Plan should be revised and extended
Hypothetic Budget Procedure April MPWT together with ARA presents basis for next year budget based on the funding for the current year. The consequences shall be described if the funding will be lower and the possibilities if the funding will be higher. September The Government presents plans and a budget proposal/bill for the coming year to the Parliament. For mayor investments funding should cover the whole construction period. November The Parliament decides upon the budget for coming year. December MPWT gives ARA Appropriation Directions, setting out the goals the Administration is to achieve, how much money it has at its disposal and how the money is to be divided among the different activities. Reports Quarterly progress report from ARA to the Government and Annual Report by the end of February the following year. Review Running review by the National Audit Office.
The Role of the Ministry ü Prepare bill for Transport Policy to be adopted by the Parliament ü Follow the traffic development and make forecasts and lay down ü ü ü a Government Vision for Transport Give Government Bodies the tasks and guidelines for preparation of preliminary Long Term Plans Merge the Plans and after consideration adopt the New Long Term Plans Yearly, as part of the Government, prepare budget proposal for decision in the Parliament Give the Authorities instructions and budget frames for next year Follow the performance of the Authorities through quarterly reports and independent audits
The Role of the PE Roads of Albania üIn line with given instructions prepare a preliminary Long Term Plan üGive basis for next year budget to the Ministry üOut of given instructions prepare detailed budget for next year üEngage contractors to carry out the planed activities üSupervise and follow up the accomplishment on the roads üReport to the Ministry every quarter about the progress and the effect on the Transport Policy Objectives, including economic result so far and prognosis for the whole year/project
