Back in November I posted about the freshly printed 8th Edition of Trip Generation. I received several requests for trip generation data, so in an effort to help the industry we've put together a spreadsheet with all of the a.m., p.m., and daily trip generation rates. With the few land uses where we feel it makes sense to use the trip generation equations, we include those in addition to the average rates. The spreadsheet also includes pass-by rates from the 2nd Edition of the Trip Generation Handbook. Here it is Download TripGeneration8thEdition. Details about the spreadsheet are contained on the top and bottom, so scroll all the way down before you ask me any questions.
Caveat emptor - we have done our best to assure the data is accurate (since we plan on using the spreadsheet ourselves). If you find any errors, please let us know and we'll post the corrected spreadsheet.
Special thanks to the apprentices - Mike Bultman, Joe Collins, Jenni Hattervig, and Kirk Pettis. They put in the time with the data entry and quality control.
Hi Mike
Stunning site, I have added it to my favorites. Just to say, I have no other favorites (say no more). Thanks for the ITE trip rates 8th edition spreadsheet. I was looking for Hotel rates. I will return and read more when time allows.
Regards

Hi Mike,
Thanks so much for the Trip Generation Spreadsheet. I know how much work that is to put all of the data in! If you ever decide to start charging for it I would be happy to pay.
Sincerely,

Mike,
What is your experience with municipalities wanting the fitted curve equation over the average rate calculations. In most cases it generates more trips and in the developer's world a higher cost participation fee. Is there any arguement to use against the fitted curve equation with the agencies when the trip generation is higher either way to use the lower number or is it acceptable everywhere to use the higher numbers. Therefore higher fees.

We don't have impact fees in the states I've worked in, so it hasn't been a big issue. We tend to follow the recommendations in the Trip Generation Handbook. We don't automatically jump to the biggest number we can calculate.

Mike: Do you know whether the ITE rates for assisted living (254) include ambulance trips? Thanks.

Dean: No guarantees, because the data is voluntarily submitted by traffic engineers, but it should include ambulances. Trip generation is supposed to cover every vehicle entering/exiting a site no matter what the purpose of the vehicle is.

Mike
This excel sheet is great. I noticed that you did not add a column for weekend/saturday rates. What are the weekend/saturday rates for land use 943 if any?
