RE: Bridger Ski Foundations HQ – TIS Memo, Updated 6/25/2025
Trip Generation
Due to the uncommon land use and daily varying vehicle trip demand of the Bridger Ski Foundation
Headquarters, existing and proposed, there is no directly applicable Land Use Code within the Institute
of Transportation Engineers (ITE) Trip Generation Manual, 11th ed. Therefore, the need for a more
specific breakdown of business activities and subsequent vehicle trip generation estimations per activity
exists. The following table displays each business activity, the frequency, and time range of each activity,
and the assumed trip generation estimate.

* Larger Anticipated Events: BSF may hold occasional larger events including coach/parent orientation,
Avalanche education classes, and First Aid/ CPR classes. These may take place up to 10 times in a year,
mostly in the evening.
For the purpose of projecting the greatest possible impact to traffic, all the evening events listed in the
table above are presented as if they will start and end during the evening peak hour period. In reality,
most events will generate traffic entering the site between 4 pm and 6pm but will conclude after 6pm
and generate traffic exiting the site closer to 7pm or 8pm. Additionally, most events comprised of
athletes and parents will have some carpooling. The reduction in traffic associated with multiple
occupants per vehicle is not accounted for in the data above. A reduction of peak hour trips could be
reduced by approximately 15% to 30%, depending on the type of event. See the attached Site Traffic
Narrative for more details regarding the proposed use of the site.
Trip Distribution
Based on the available Average Annual Daily Trip (AADT) data provided by The Montana Department of
Transportation, it can be assumed that the trip distribution will be evenly split (50/50) between
Northbound and Southbound on N Rouse Avenue.
Table 1: MDT AADT Data
Transportation Impacts
Due to the lack of existing Turn Movement Counts (TMC) data, it is not possible to make objective, data
based conclusions on the operational impacts of N Rouse Avenue and its intersections with E Bryant
Street and Bond Street. However, because of the low daily and peak hour vehicle trips, it can be
assumed that there will not be any appreciable impacts on the transportation network due to the
development of the Bridger Ski Foundation Headquarters at 1606 Gold Avenue. Therefore, no offsite
transportation improvements are proposed as part of this project.

Sites were selected due to their proximity to site.
Pulling two data points along the same corridor
without any major intersections between them
typically will contain similar data, secondary
