Can anyone help David with his request, see below? In particular I was thinking that Cath Lawson, Shawn Turner or Carl Petty might know of something specific. Besides, this might be a break from papers. So far of the 51 papers we are playing with there are 53 of the 192 outstanding reviews turned in. -----Original Message----- From: David Corley [mailto:rcorley@siue.edu] Sent: Tuesday, August 29, 2006 2:41 PM To: Murakami, Elaine Subject: Speed data for urban commercial vehicles. Hello. I am an mechanical engineering student working on my senior project. I am looking for speed profile data for a commercial vehicle driving a typical urban route. Specifically I am looking for something like a text file with the speed of the vehicle sampled twice a second. Is this data available from your organization? If not, do you know where I might find such data? Thank you David Corley Southern Illinois Univeristy Edwardsville. ------------------------------------------------- SIUE Web Mail -------- Original Message -------- Subject: RE: Speed data for urban commercial vehicles.

Most of the work I have done has used GPS, so it is limited to 1-second intervals. Also, most commercial fleet management software uses GPS, so has a similar limitation. You will probably have a lot of difficulty finding a public dataset with sub-second data, combined with GPS, because it would most likely need to be tied to the OBD. You best bet is to find someone at EPA ( I just left a voice mail for someone at EPA in Ann Arbor). IF (big IF) they have something like that you and your professor would need to sign a confidentiality agreement to have access. Another potential source is the California Air Resources Board. You could try Bob Leore at Transport Canada, who did a presentation in Minneapolis at the NATMEC conference on combining OBD-II and GPS. I didn't attend his presentation, did not get a copy of his ppt, so I don't know if he has implemented any data collection, and if so, on what vehicles. I don't have his email address, and it wasn't on the conference list of attendees! I'm sure you can find it. I will CC Ed Christopher who chairs the TRB urban data committee. Maybe he knows of some other possibilities. Or, you could try posting your query on the TMIP listserv. Elaine Murakami FHWA Office of Planning (Wash DC)
