4. HOW DO WE MEASURE ECONOMIC
EFFICIENCY
• Cost-benefit analysis is the key way to measure the economic
efficiency of investments or measures
• What is cost-benefit analysis?
– A consistent and systematic quantitative comparison of the effects of an
investment or a measure
• What is the purpose of cost-benefit analysis?
– To summarise the advantages and disadvantages of an investment or
measure as the foundation for a political decision
– If advantages (benefits) outweigh the disadvantages (costs) it is an
efficient investment or measure
5. WHY DO WE INVEST IN TRANSPORT?
• Originally to get from A to B
• … then to get from A to B fast
• … last 2-3 decades attention has been given to avoiding the
negative externalities of transport
• The later years
… high congestion implies optimisation of the use of the
infrastructure
… increase the urban space and recreational value
… for cycling projects also to gain health benefits
• We want to assign an economic value to each of these effects

11. PERSPECTIVE
• Bicycle projects
… can and should be assessed in the same way as other
transport projects
… can yield economic returns on investment that are
comparable with other modes of transport
… have an important contribution to public health which
should be included in the cost-benefit analyses
… but the methodological foundation for assessing cycling
should be developed further as we are only in the early stages
