12. These more guidance on engineering: utilities and roundabouts, paving, phasing, etc.
13. That strong differences still exist on design philosophy.
14. [It is] still a new field so more data points on all fronts (design, operations, multimodal, etc.) is very helpful. More case studies of unusual applications.
15. Networking with people and learning specialties and who to ask.
16. About NCHRP 672.
17. Better information about capacity software.
18. Some of the design guidance people are using and how they have functioned.
19. More lessons learned, carrying about issues and solutions used. More complicated design guidance, more of the next phase of designers for two or three Lane roundabouts.
20. The confidence we have as a group of professionals to do good design in simple and complex roundabout intersections.
21. More confidence in signing and striping guidelines – it evolves over time, but never is standard across countries/states/provinces.
22. Path entry overlap and geometry design issues.
23. Intersection analysis/justification to quantitatively justify/determine effective intersection – micro (small) and macro (network) affect.
24. Technical exercises with a few cases with a roundtable discussion with a small group..
25. We can learn more from other agencies failures then we can from their successes.
26. from the standpoint of a new roundabout designer, probably the most important things needed are: specific design training and capacity software.
27. Mini roundabouts.
28. Additional design information, including site selection, traffic volumes and geometrics. information on prevention of path overlap, not just at the approach but at the exits.
29. Just hearing more options on so many aspects of roundabouts.
30. Can't wait until this conference is online
31. Mini roundabout sessions.
32. FHWA more firmly pushing roundabouts and states. Better guidance on curb types/best practices/ trucks. Guidance from NFPA about roadways to deal with fire departments that insist on 20 to 27 foot minimum paving list due to ISO ratings.
33. Thoughts on striping multilane roundabouts, particularly as it relates to trucks.
34. human factors research related to driver perception of metering signals in roundabouts. How close can you please a signal to a yield sign and not close driver confusion?
35. Do not over design!
36. Information on what is the best way to construct it and how to diverge traffic – digital file given to contractor versus wooden stakes.
37. Let's hear from our contractors on methods of construction for roundabouts. How to make them last longer? How to construct them faster? How should the plans be organized – more spot elevations, more profiles, fewer cross-sections?
38. Experience and education.
39. FHWA website soon, will be very comprehensive and peers are available to help.
40. Continued research re capacity, bicycle and pedestrian accommodation.
41. Learned more about truck accommodation.
42. Need to learn more about how roundabouts affect traffic operations at adjoining intersections and vice versa. Need to learn what we can do to mitigate the effects.
43. The discussion on large vehicles at roundabouts.
44. National consistence on design science.
45. Coordination and cooperation with other designers.
46. Global status of roundabouts and lessons learned.
47. Tools for public education to gain support in general for roundabouts.
48. Yielding issues of pedestrians and cars/bicycles. Effective research and materials to help demonstrate to the public the safety of roundabouts to all users.

No occupation specified

1. The truck study – things that give a higher confidence associated with accommodating trucks and oversized loads.
2. More details and public awareness and education.
3. . The effect of the first roundabout in a community – we need to follow good procedure.
4. The problem of pedestrians and cyclist.
5.  Methods for roundabout winter management. They have not yet been developed.
6. Consideration that road diet. I think that was what was meant ][and roundabout is interesting and important.
7. Influence of whether, i.e. snowfall.
8. Safety issues and how to deal with them.
9. Conferences (peer to peer) exchanges with equipment jurisdictions.
10. Training for designers and planners using ITE and other professional associations.
11. An enhanced prequalification system for designers and reviewers to ensure proper roundabout design
12. Safety concerns. Lifecycle costs.
13. Some different types of roundabout analyses.
14. I am new to roundabouts. I just need to educate myself more. Especially when to use a roundabout.
15. Exposure to roundabouts in Carmel.
16. More case studies – both pro and con for roundabouts. Less infomercials by software developers.
17. Make sure that the plans [roundabout?] are built to the plans, striping can fix a bad plan.
18. Educational material for" non-" engineering community, local politicians and students.
19. Guide to applicability of various models.

Academia/Grad Students

1. More research on perception and visibility of roundabouts and on their effects on safety improvement.
2. INDY cars are loud and fast!
3. Guidance for roundabout analysis. Engineers used tools (SIDRA, RODEL, VISSIM, [unreadable]), and the developers are the ones who give guidance – there is need for independent comparison.
4. Availability of case studies with information collected at local and these are at state levels.
5. Basic design principles.
6. Capacity is stochastic as well as deterministic.
7. Access to national database of all types of data collected at roundabouts: e.g. critical gaps, follow-up headway, safety data, geometric design details and context I which roundabout was installed.
8. A level discussion on all the benefits and costs of a roundabout in comparison to a regular intersection. Traffic performance, vehicle safety, pedestrian safety, ADA.
9. I was also impressed how low is the public acceptance of roundabouts [in the USA
10. More specific results about roundabout traffic safety and comparison.
11. Education is important! There does not exist a roundabout in Japan – field of relational test only.
12. I'd like to know the technique of education methods.
13. More research funding for roundabouts.
14.  Install a roundabout for the first time in a noncritical area of the community. Put the roundabout in a position to win.
15. Education issues associated with roundabouts.
16. Guidelines on appropriate type of intersections based on various conditions. More case studies on the safety features of roundabouts.
