<br /> Kittitas County Model Update | 2 <br />Task 1. Project Administration <br />This task includes coordination with the County and cities throughout the project. At a minimum, <br />monthly meetings are assumed, but more could be scheduled as necessary based on the specific <br />needs of the project at a given time. This task also includes the preparation of monthly invoices and <br />progress updates. <br />Task 2. Data Collection <br />To validate the volume estimates generated by the model, a database of existing traffic data is <br />required. This data will be compiled through traffic count vendors and provided by the cities and <br />County, as available. Fehr & Peers will organize and standardize the count data into a consistent <br />format that can be used for model validation. The cost for this task assumes that 24-hour tube counts <br />are collected at 80 locations, with approximately 75% collected across the county during Winter <br />2026 and 25% collected in the Upper County during Summer 2026. <br />In addition, Fehr & Peers will purchase origin -destination travel data, from a data provider such as <br />Streetlight, to provide information on travel behavior within the subarea for each of the validation <br />time periods. This data will be used to calibrate the proportion of trips generated within the subarea <br />and the proportion of trips coming from outside the subarea. Fehr & Peers will process and <br />summarize the data for use in the travel model. <br />Task 3. Existing Scenario Update <br />As part of this task, Fehr & Peers would review the arterial and highway network for consistency with <br />existing conditions throughout the entire county. This includes verifying characteristics such as the <br />number of lanes, functional classifications, speed limits, and turning restrictions. The roadway <br />network would also be updated to include more roadways to a level of detail consistent with the land <br />use zone system in the model. <br />In order to better estimate travel to and from the Upper County area, a new land use category would <br />be added to the structure of the model for households that primarily function as second homes and <br />vacation rentals. A separate trip purpose would also be added to the model to distinguish recreational <br />travel from the other trip purposes currently in the model. Travel assumptions for the new land use <br />category and trip purpose would be estimated using the travel data collected in Task 1. The Upper <br />County area of the model includes a sufficient number of land use zones and the boundaries of these <br />would not be substantially altered. <br />The County and cities would be responsible for providing changes in households and jobs that have <br />occurred since 2017 to be incorporated into the model. Fehr & Peers would be responsible for <br />updating volume assumptions at each of the gateway locations in the subarea model. <br />Task 4. Existing Scenario Calibration and Validation <br />The model will be calibrated and validated to reflect travel conditions during a Winter 2026 weekday <br />PM peak hour and Summer 2026 weekend peak hour. This will be accomplished by adjusting trip <br />generation rates, the proportion of internal vs external trips, roadway network characteristics, and <br />other parameters that affect travel behavior. The validation will compare existing traffic counts with <br />model estimates for the peak hour for both the countywide model and Upper County subarea.
