2015 TRB SUMMER MEETING

JOINT MEETING OF

AHB65 — OPERATIONAL EFFECTS OF GEOMETRICS COMMITTEE

https://sites.google.com/site/trbcomahb65/

AFB10 — GEOMETRIC DESIGN COMMITTEE

http://sites.kittelson.com/TRB-AFB10

Sunday, June 21, 2015

5:15 pm to 6:15 pm, Mackenzie II

Vancouver, Canada

1. Call to Order (Fitzpatrick/Donnell)

AHB65 Chair Kay Fitzpatrick and AFB10 Chair Eric Donnell called the meeting to order at 5:25 pm.

2. Welcome and Introductions (Donnell/Fitzpatrick)

3. 5th International Symposium on Highway Geometric Design, 2015 (Harwood)

Doug Harwood recognized the tremendous efforts of Milton Carrasco, his colleagues at Transoft and others who put together the 5th International Symposium on Highway Geometric Design (the Committees gave a great round of applause).

325 people from 37 countries are registered for the Symposium. There have been active discussions for the 6th Symposium; 2 potential hosts have already contacted Doug. Eric Donnell thanked Milton and Doug for their efforts (to another round of great applause).

4. 2016 Summer Meeting jointly with AASHTO (Donnell)

Eric Donnell and Jeff Jones (AASHTO) have discussed meeting jointly in 2016. Rich Cunard has reserved meeting space in Woods Hole, MA from Tuesday 7/12 through Thursday 7/14, with AASHTO then meeting alone on Friday 7/15. Might switch to a different venue, but it would be changed soon, if at all.

Roads,” etc.; (3) other research, e.g. performance-based design related; (4) other research outside the guides: e.g., hard shoulder running; bus rapid transit. Need to develop priorities. AASHTO is excited about meeting with us.

Kay asked about the timeline for the next edition of the Green Book. Jim Brewer responded that while there is no deadline, they want it available as soon as possible. There is a lot of good research that could be incorporated. AASHTO will review research and discuss next month (July 2015); after that they will have a better feel for the timeline. They are working towards it now. Researchers working on projects now should consider presenting, if it fits into one or more Green Book chapters.

Eric put in a plug for mytrb.org and suggested that everyone go to the site and register. Identify your interest in a committee(s) and you will be contacted. Rich Cunard noted that in order to submit a paper, one needs to create a mytrb account.

5. 5th Urban Street Symposium, 2017 (Fitzpatrick)

Due to the success with the 4th Urban Street Symposium (USS) in teaming with ITE, we are looking to team with an ITE section on the 5th USS.

The North Carolina section of ITE wants to join and host in Charlotte or Raleigh in 2017. The USS has not been held on the east coast yet. We want a place that is progressive with good examples of alternative/innovative intersections and interchanges - North Carolina qualifies on both accounts. Volunteers are welcome.

6. 2016 Annual Meeting Workshop on “Benefit/cost analysis for informed design decisions at various stages of the project development process (working title)” (Porter/Steyn)

RJ Porter: the deadline was last Friday to submit ideas for the workshop.

The workshop will look at monetizing performance measures to support design decisions. A small steering committee has been established, which includes Keith Knapp, Hermanus Steyn, Kay Fitzpatrick, and Eric Donnell. Can use more volunteers…

Will develop a vision for the workshop in July and extend preliminary invitations to speakers. Then, will refine the scope and finalize based on the speakers.

Discussion:

 Kay: in assigning costs for crashes, different assumptions can be made. How influential are they?

 Eric: the AASHTO Red Book (“User and Non-User Benefit Analysis for Highways”) looks at user highway analysis in project development

 Brian Ray: move beyond just traditional construction costs; reflect beyond the lifecycle to look multi-dimensionally at what benefits and costs are

(3)

 Jim Brewer: talked with FHWA about updating crash costs, which haven’t been updated in a while. There is a proposal to get the national insurance institute to develop new numbers; need to re-do.

 Doug agrees with Kay. He talked with a number of states and got a range of $1M to $9M per fatal crash. Rich Cunard said that the federal government has same issue; FHWA has a different set of crash costs than NHTSA, which is different than what some states use.

 Karen Dixon: NHTSA figures are based on injury, FHWA figures are based on crash  Eric: Forrest Council wrote a report on this (2004-05?)

 Doug: this is timely since the 2nd Edition HSM is in the works; need to update costs  Eric: reach out to cross-cutting committees; reach out to ANB25 and others

 Kay: remember that the workshop is on B/C, while this discussion has focused just on costs. Seems to be blossoming into a topic on its own.

 Howard Lubliner: FHWA promotes cost analysis throughout the design process; giving better tools; evolution through the design process

 Jim Brewer: has to be meaningful for the practitioner  Kay: value of time could be another presentation

 Rich Coakley: another topic is maintenance effects (aspects of design and how they affect the cost of maintenance)

 Jim Brewer: sustainability is very important; a 20 year design is not enough in some areas. Performance-based design is not effective if you have to come back in 15-20 years and do it again.

 Pete Jenior: all these topics argue for someone on the economic side to be involved (Red Book)

 Hermanus: may not have all the answers going into the workshop, but we should identify research needs

 Eric: consider a synthesis topic on crash costs and B/C estimation

 Rich Cunard: 2 economic-based committees could be involved: (1) Transportation Economics; (2) Social and Economic Factors in Transportation

 Hermanus: need to have all speakers lined up by September

 RJ: health impact assessments – reduced health care costs resulting from improvements

 Eric: have a lot to consider, e.g. safety, operations, environmental, reliability, public health, etc.

7. Research Needs Statements (Brewer)

Marcus Brewer gave a presentation on Geometric Design Research (see attached slides). Discussion included:

 Rich Coakley advised that we put on the radar the impact of connected vehicles / automated vehicles on geometric design. Need to develop a RNS on this.

 Eric has been looking at connected vehicles, etc. If it can be turned into a RNS, then we will do it.

(4)

Updated: 1/4/2016 4

 Jim Brewer noted that implementation dates for connected vehicles have a very wide range – from 10 years to 50 years.

 Eric said to contact us if you need help with developing a RNS (e.g., if you’ve never done one before). They are not too hard to do.

8. Plans for 2016 TRB Annual Meeting

Kay noted that at the 2015 Annual Meeting we had a joint AHB65-AFB10 meeting on Monday before the subcommittees met. She asked if anyone had any thoughts on whether that worked well or not (i.e., is it good to have a joint meeting to start? Is it better to have the full committee meetings before or after the subcommittees meet)?

Doug likes Tuesday better for the main committee meeting, but is OK with Monday. Kay favors a joint meeting on Tuesday and then breakout to separate meetings. Eric will request Tuesday.

9. Release to separate meetings (Fitzpatrick/Donnell)
