The operational characteristics of an intersection are determined by calculating the intersection level of service (LOS). At signalized intersections, LOS is measured in average control delay per vehicle and is typically reported using the intersection delay. Traffic operations and average vehicle delay for an intersection can be described qualitatively with a range of levels of service (LOS A through LOS F), with LOS A indicating free-flowing traffic and LOS F indicating extreme congestion and long vehicle delays. Appendix A contains a detailed explanation of LOS criteria and definitions. According to the City of Renton Comprehensive Plan, the citywide level of service standard for arterials and collectors (includes all roads within the study area) is LOS D. Weekday peak hour traffic operations for existing and future without-project conditions were evaluated at the study intersections based on the procedures identified in the Highway Capacity Manual (HCM 6) and were evaluated using Synchro 11. Synchro 11 is a software program that uses HCM methodology to evaluate intersection LOS and average vehicle delays. Signal timing was assumed consistent with the existing timing for the Southport West TIA recently completed in the vicinity. Analysis parameters such as lane channelization and signal timing were maintained for future 2031 without-project conditions relative to existing conditions. Results for the existing and future without-project operations analyses are summarized in Table 2. Detailed LOS worksheets for the existing and future without-project analysis are included in Appendix B. Table 2.

Table 2 shows that under existing conditions, the study intersections operate at LOS C or better during the weekday AM and PM peak hours, meeting the City’s LOS standard. With the addition of background growth under future without-project conditions, both study intersections are expected to continue operating at the same LOS as under existing conditions, with increases in delay of up to 4 seconds.

Intersection LOS was calculated using the methodology described previously. The without-project conditions are compared to the with-project conditions to understand the potential traffic impacts of the proposed project. Table 6 summarizes the 2031 without- and with-project intersection operations for the weekday peak hours. LOS worksheets are included in Appendix B. Table 6.

As shown in Table 6 with the addition of project traffic, the off-site study intersections are anticipated to continue to operate at the at LOS C or better during both AM and PM peak hours, meeting the City’s LOS standard with minimal increases in delay with the project. Site Access Analysis The proposed project includes a primary site access provided adjacent to the Phase 2 site via Park Avenue N (see Figure 2). Additional access via Logan Avenue is also provided via Phase 1 of the project. All accesses are proposed to be side-street stop controlled. The traffic operations at the primary site driveway along Park Avenue N was evaluated under future with-project conditions for the weekday AM and PM peak hours. The operational analysis was consistent with the methodology described above. LOS worksheets are included in Appendix B. As shown above in Table 6, the Park Avenue N site access is anticipated to operate at LOS B or better, under future with-project conditions during the AM and PM peak hours, meeting the City’s standards. In addition, 95th percentile vehicle queues at the Park Avenue N site access (neither the northbound left-turn inbound nor the eastbound right-turn outbound) are not anticipated to exceed 1 vehicle during both weekday AM and PM peak hours.
