Research aim and question

Aim:

• How can the effects of cycling policies be appraised in ex-ante assessment from a holistic perspective?

Questions:

1. What are the determinants of bicycle use?

2. What are the effects of bicycle policies?

3. How can such effects be appraised from a holistic perspective?

4. What are the main benefits and the costs of investing in fast cycle routes byapplying this perspective?

5. What are the opportunities and limitations can be identified in theapplication of this approach to social cost-benefit analysis?

Attractiveness of cycling

“Notably, the attractiveness of cycling is inversely linked to the attractiveness of

car driving, and measures to re-designate car lanes and car parking are both

psychologically important to support cyclist identities, and physically necessary

to accommodate growing cyclist populations” (Gossling & Choi, 2015)

Effects of Cycling Policies

• Internal vs external

• Intended vs unintended

• Direct vs indirect

• Prized vs non-prized

• Factors affecting their magnitude:

• Number of users and amount increase

• Type of bicycle (e-bike, normal bike...)

• Travel purpose

• Exogenous factors

Holistic appraisal

Methodology

•Desk research (statistical / policy document analysis / Bike Print)

•Field research (VU seminar / qualitative analysis)

•Unstructured / semi-structured interviews

•3 feedback sessions

•2 expert panels

•Social cost-benefit analysis of fast cycle route

Qualitative problem analysis

• Bad asphalt quality

• Unsafe intersections

• Mixed traffic

• Noise

• Bushes on the cycle path

• Sometimes indistinguishable path

• Fast cycle route:

• High quality asphalt

• Wind schield

• Prioritised

• Reduced intersectios (safety)

• Option value

• Amenity value

• Attractor of tourism

• Behavioural campaign

Supply management approach

Method

• Geographical – temporal definition

• Impact model

• Pre-post estimates

• Valuation

• Methodological consideration:

• Uncertainty incorporation = conservative estimates + scenarios

• Better approximately right than precisely wrong approach

Policy recommedations

• Realistic and optimistic have positive results

• However:

• Only single alternative has been analysed (other alternatives more efficient?)

• Low level of social interaction & low recreational facilities on the way even if the fast cycle route will be built (risk)

• Faster cyclists or faster scooters?

• Noise pollution from the incoming / departing flights (no intervention can be done)

• No intervention on the supply side of cars

In line with previous studies

(Source: Elvik (2000); Saelensminde (2004); Wang (2005); Norden (2005); COWI (2009); Borjesson & Eliasson (2011); Decisio (2008); van Ginkel (2014); Gossling & Choi (2015); Decisio (2015).

Conclusion

• Holistic appraisal requires systems thinking and knowledge integration

• It also requires collaboration between multiple stakeholders and agreement on the assumptions

• SCBA is a valuable tool to assess costs and benefits of cycling infrastructure but the ability to make more accurate assessments highly depend on the quantity and quality of data

• However, cycling goes beyond health benefits and travel time savings...
