Roseville Starbucks Traffic Study September 30, 2022 Page 7 Trip Generation To account for traffic impacts associated with the proposed development, trip generation estimates were developed for the weekday a.m. and midday peak hours, as well as on a daily basis. These estimates, shown in Table 3, were developed using the ITE Trip Generation Manual, 11th Edition. Table 3. Trip Generation Estimate A.M. Peak Hour Midday Peak Hour Land Use Type (ITE Code) Size Daily Trips In Out In Out Coffee/Donut Shop with Drive- 2,250 SF 98 95 49 49 1,201 through Window (937) Results of the trip generation estimate indicate that the proposed development is expected to generate 193 weekday p.m. peak hour, 98 weekday midday peak hour, and 1,201 weekday daily trips. The trips generated were distributed to the study area based on the directional distribution shown in Figure 4, which was developed based on a combination of existing daily traffic volumes/travel patterns, information from the previously completed AUAR, and engineering judgment. The resultant year 2024 peak hour traffic forecasts, which include general background growth and trips generated by the development, are illustrated in Figure 5. Year 2024 Build Conditions Intersection Capacity Analysis To determine how the study intersections will operate under year 2024 build conditions, an intersection capacity analysis was completed using Synchro/SimTraffic software (Version 11). Results of the year 2024 build intersection capacity analysis shown in Table 4 indicate that all of the study intersections are expected to continue to operate at an acceptable overall LOS B or better during the a.m. and midday peak hours. There is not expected to be any internal queuing issues entering or exiting the proposed development along Twin Lakes Parkway, with average queues of one (1) vehicle and 95th percentile queues of two (2) vehicles at the right-out access. No other significant side-street delays or queuing issues were observed at the study intersections. Table 4.

(2) Indicates an unsignalized intersection with side-street stop control, where the overall LOS is shown followed by the worst approach LOS. The delay shown represents the worst side-street approach delay. (3) Indicates a roundabout intersection with all-way yield control, where the overall LOS is shown.
