This property has previously served as an Interstate 90 rest area site owned and maintained by the Montana Department of Transportation. The development proposal evaluated with this trip generation comparative analysis includes a hotel and a fast-food restaurant with a drive-through window. Traffic data for the rest area site has been previously obtained with multiple counts. The most representative counts I have available were completed on Tuesday, May 2, 2017, by me while employed with Morrison-Maierle that were included with the original Traffic Impact Study: Simmental Property – Lots 1-3 of Tract 1 & Lot 1 of Tract 2 of Gardner Simmental Plaza dated November 2019 (Morrison-Maierle Project No. 6082.002). Estimated average weekday traffic as well as weekday, AM and PM peak hour trips for the rest area site are summarized in the table on the following page. Estimated average weekday traffic volumes were calculated utilizing the following formula: 𝐸𝐴𝑊𝑇= 10(𝐴𝑀2 +𝑃𝑀2) 𝐴𝑀+𝑃𝑀 The above counts were deemed to be the most representative for the site based on the time of year that they were completed, which would be after the winter season and prior to peak summer tourist season. It is not anticipated that a rest area would experience significant yearly variations in site generated traffic. The access to the rest area only served that site; therefore, there would also not be expected changes to traffic volumes due to growth in the surrounding area. Estimated trip generation for the proposed development was derived utilizing rates published by the Institute of Transportation Engineers (ITE) in the Trip Generation Manual, 11th Edition. The rates used in the analyses were based on the all-suites hotel (ITE Land Use Code 311) and fast-food restaurant with drive-through window (ITE Land Use Code 934) land uses with a general urban/suburban setting or location. The number of rooms for the all-suites hotel and the proposed gross floor area of the fast-food restaurant were used as independent variables. where: EAWT = Estimated Average Weekday Vehicular Trips AM = Weekday, AM Peak Hour Vehicular Trips PM = Weekday, PM Peak Hour Vehicular Trips Trip Generation Comparative Analysis for the Reststop ZMA Application City of Bozeman Planning Project No. 24185 June 7, 2024 20240607_22-0117_Trip-Gen-Summary Page 2 of 3 The all-suites hotel has been evaluated based on an estimated 180 rooms. The fast-food restaurant with drive-through window trip generation estimate is based on a proposed 5,338 square feet (ft2) of gross floor area. Based on the ITE trip generation rates, the proposed project is estimated to generate a total of 3,314 average weekday vehicle trips, 303 AM peak hour, and 245 PM peak hour trips. It is estimated that the weekday, AM peak hour will occur concurrently with the peak hour of the adjacent street traffic (one hour between 7:00 and 9:00 a.m.). Pass-by trips are projected to represent a portion of development traffic related to the fast-food restaurant with drive-through window evaluated as part of this analysis. Pass-by trips are those that result from traffic passing on an adjacent roadway that enters the site and then exits, resuming travel in the same direction. Pass-by trips are anticipated to account for 49% of fast-food restaurant traffic during the weekday; 49% during the weekday, AM peak hour, and approximately 50% during the weekday, PM peak hour. Pass-by trip estimates were obtained from the ITE Trip Generation Handbook, 3rd Edition for ITE Land Use Code 934 except for weekday estimates. A weighted average of weekday, AM and PM peak hour pass-by trips was utilized in estimating weekday pass-by trip composition. The estimated vehicular trip generation for the proposed development is presented in the table below.

The weekday, AM and PM peak hours are also forecast to experience increases of 236 and 194 trip ends, respectively, with the proposed development. Usage of ITE trip generation rates can produce conservative estimates based on the locations, size of developments, and characteristics of the surrounding area where studies were completed that were utilized in development of the rates found in the Trip Generation Manual. Thank you for the opportunity to work with you on this project. I look forward to serving you in the future. If you have any questions or concerns regarding the analyses, please do not hesitate to contact me.
