Traffic Analysis. Prepare a memorandum summarizing all The purpose of this activity is to evaluate existing and proposed traffic conditions. Documentation of the operational analysis will be prepared under the WSDOT coordination task for the ICE. The work performed in this task will support the ICE, but development of the documentation required for the ICE is included in the WSDOT coordination task efforts. Task 7.1 – Traffic Operational Analysis along Data Collection and Evaluation The CONSULTANT shall collect existing traffic turning movements at the studied corridor. In addition to reporting the study process and findings, corridor and intersection recommendations shall be documented to meet for use in the traffic demands for future yearanalysis. Provide recommendations Traffic counts will be collected at the NB and schematic exhibits of recommended improvements in signed sealed reportSB I-5 ramp intersections with Tumwater Blvd. EOR shall coordinate with the traffic provider for the completion CONSULTANT will perform a review of the traffic tasks, which shall be included data collected. Task 7.2 – Existing Conditions Evaluation The CONSULTANT will review existing traffic data collected for the project for use in the Study Phase Report or Design Plans.
A. traffic analysis. Existing conditions and deficiencies will be documented. Task 7.3 – Traffic Study Volume Projections The CONSULTANT shall develop traffic volumes for the opening year of the roundabout, and Coordination o Submit a memo outlining the sources design year of the roundabout for use in the traffic count analysis. Traffic projections will be determined using historical data and methodology used to estimate the local traffic model growth projections. CONSULTANT will coordinate with WSDOT Olympic Region traffic staff for approval of traffic projections. Traffic volumes before proceeding to the analysis phase. o Conduct turning movement counts at the following intersections for 13 hours each to conduct Signal Warrant Analysis. o Intersections: • Fairmont Pkwy & Genoa Red Bluff Rd/Canada • Fairmont Pkwy & Pecan Crossing Ln/New West Dr • Fairmont Pkwy & ▇▇▇▇▇▇▇▇▇ ▇▇ o Additionally, a 24-hour automatic tube recorder count shall be conducted. • East of Fairmont Pkwy & Pecan Crossing Ln/New West Dr intersection o Perform field observations for observing existing traffic patterns o Perform Traffic Warrant Analysis for the three intersections listed above using TMUTCD guidelines.

D. Future Conditions Analysis and Recommendations o Estimate future conditions capacity including delay, v/c ratios, traffic queues, and LOS for the study area intersections listed under Task 2 for typical weekday AM and PM peak hours. This shall be used as a base condition scenario for comparison with proposed alternative scenario. Any capacity limitations in no-build scenario shall be identified and recommendations shall be made as part of a preferred alternative. o Use Synchro software to analyze signalized and unsignalized intersections, whereas Sidra shall be used to estimate operations at proposed Roundabouts. Develop Synchro model to determine the impact of proposed alternatives on roadway network. o Recommend improvements to signing and or pavement width to improve circulation. Assumptions:
1. Analysis will be developed for the AM and PM peak hours for existing conditions, the opening year of the roundabout, and the design year of the roundabout. Task 7.4 – Traffic Analysis The CONSULTANT shall perform an operational analysis for the improvements at the intersection to satisfy the requirements of the ICE. The analysis will evaluate existing conditions, a traffic signal, and a roundabout. The roundabout will be evaluated using Sidra software and the signal alternative will be evaluated using Synchro. The traffic analysis will follow WSDOT’s protocol for analysis program settings. The operational analysis will include evaluation of future operations of a multi-lane roundabout at the SB I-5 ramp intersection with Tumwater Blvd to confirm that there are no issues with queuing between the intersections in the future. The SB I-5 ramp terminal will not be evaluated for the interim conditions. Traffic operations for the NB I-5 ramp terminal will be analyzed for the following three scenarios: Existing• Existing conditions AM/PM peak hours (existing control, Future Noroundabout, traffic signal) • Opening year AM/PM peak hours (existing control, roundabout, traffic signal) • Design year AM/PM peak hours (existing control, roundabout, traffic signal) Traffic operations for the SB I-5 ramp terminal will be analyzed for the following scenarios: • Design year AM/PM peak hours (roundabout only) Task 7.5 – Alternatives Evaluation The CONSULTANT will perform a high-Build level evaluation of a roundabout and Future Build a traffic signal for the intersection improvements. The evaluation criterion will include safety, operations, environmental impacts, maintenance, and R/W footprint. Consultant will coordinate with Improvements.

Documentation of the alternatives analysis process and the results and recommendations are included in the efforts for developing the ICE and the ARR in Task 5. Task 7.6 – Sensitivity Analysis The design team will evaluate the results of the operational analysis to determine the appropriate opening year, or interim, configuration for the roundabout. The sensitivity analysis will evaluate the anticipated year the corridor and intersection traffic will exceed the capacity of a single lane roundabout and document the recommended opening year configuration and design approach for future expansion of the roundabout, if needed. Traffic volumes and volume projection data will be provided as part used to evaluate the interim and ultimate configurations of the deliverablesroundabout. However, a detailed design is NOT included as part Sensitivity Analysis Memo – This task includes development of the scope section of workthe ICE that covers the sensitivity analysis. No separate deliverable will be developed for the sensitivity analysis.
