Background• Different city characteristics- transport and traffic conditions (infrastructure, traffic control
and management, etc.), geographical, environmental, demographic, socio-economic as well as institutional frameworks
- sucess in one city does not gurantee sucess elsewhere• Important to identify key factors to ensures the measure‘s
success in new location. • Valuable to identify barriers so that they can be
addressed/overcome

Transferability• Process of verifying the
chances of a successful implementation of a measure which has proved successful elsewhere
• Analysis of relevant factors
• Opportunity to learn lessons from the previous experience and to avoid mistakes!

Step 1: Mission statement and scope
• A clearly defined mission statement (or clear objectives) and a realistic scope for a measure
• Should avoid any misunderstanding during the subsequent transferability and implementation processes
• Rest of the transferability steps should only be carried out after the adopter understands and agrees with the objectives and scope of the measure
![Page 7: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/7.jpg)
Reading’s open data
Mission statement• To make traffic data available in open data server to
encourage apps based traveller information
Scope • Management of data from traffic management and control
systems only. It does not cover the traffic management control systems.
![Page 8: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/8.jpg)
Step 2: Impacts
• Efficiency (capacity, journey time) • Environment (emissions, noise, visual intrusion)• Safety• Accessibility• Vehicle occupancy• Benefit-to-cost ratio (BCR) • Multi-Criteria Analysis (MCA)
![Page 9: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/9.jpg)
Impacts (Reading’s open data) • Wider dissemination of traffic/travel information• Potential to address specific user needs (e.g. elderly and
disabled).• Reduce passenger waiting time• More informed and better travel choices leading to modal
change to public transport • Increase bus patronage and revenue• Support to some economic activities in the area (apps
development)

Step 3: Up-scaling
Determination of up-scaling (or scaling down) need:
• To match the city’s need
• To recognise the requirements and implications
• e.g. Route -> City-wideSource: Dziekan et al, 2013
![Page 11: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/11.jpg)
Scaling (Reading’s open data)
• Reading is much smaller than London and hence the scale of implementation is much smaller
• This may have implications on system requirements, costs and benefits – especially demand for the information
![Page 12: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/12.jpg)
Step 4: Main components & characteristics
Factors that can contribute to the success (or failure) of a measure :
• Components (main factors):- Policy, stakeholders, finance, technical requirements, etc.
• Characteristics (sub-categories) e.g. for policy:- Public transport policy, traffic management policy,
accessibility policy, pollution reduction policy

Step 5: Level of importance of characteristics
According to the adopter city
• High/medium/low• Supporting comments
![Page 15: TIDE Transferability Methodology TIDE Final Conference Barcelona, 15-16 September 2015 Birendra Shrestha Senior Traffic Modeller, Transport for London.](https://reader037.fdocuments.in/reader037/viewer/2022110211/56649ee85503460f94bf98c3/html5/thumbnails/15.jpg)
Importance of characteristics (open data)Characteristics Importance Comments
Open data policy High The main objective to be supported by the measure
Traffic management policy
High Open data supports overall traffic management policy
Capital costs Medium The implementation cost is relatively lower than the infrastructure providing data
Running costs Medium Similar to existing ITS systems
Urban Traffic manager High Traffic manager were in favour of fewer priority interventions as a result of advanced priority, but concerned over potential complexity
Bus operators High Operators needed to be convinced the about the benefits of open data
Local government High Local government needs to approved and financed the scheme
Market demand High Market demand influences the involvement of 3rd parties in apps development
Data quality High Good quality data is needed to assure apps developers and travellers

Step 6: Assessment of characteristics
Subjective assessment of ease/difficulty in implementation by adopter city Assessment scale:
+2 strong support for transferability+1 modest support for transferability 0 neutral
-1 modest constraint for transferability -2 strong constraint for transferability

Step 7: Conclusions
Drawing conclusions through the assessment
• One or more strong constraints (-2) to transferability- no transfer unless the conditions can be overcome
• One or two modest constraints(-1) (no strong constraints)- difficult to transfer the measure unless the conditions can be addressed
• If there are no constraints at all- likely that the measure could be successfully transferred

Conclusions (Reading’s open data)• The measure is potentially transferable to Reading
dependent on:
• Data quality – Needed to make sure that the data available is reliable
• Market demand – pump priming may be needed to develop initial apps and generate interest amongst apps developers and travellers
