SCOPE OF WORK (continued) <br /> apply due to unique interchange or intersection designs,the project team will coordinate with WSDOT to confirm <br /> the appropriate approach to documenting potential safety impacts or benefits. <br /> After a Preferred Alternative is selected,VISSIM will again be used to evaluate phasing of the proposed <br /> improvements, including interim year 2040 analysis.The interim year volumes will be used to evaluate the <br /> benefits and impacts of individual components of the preferred alternative that could be implemented early. <br /> Assumptions <br /> • Crash modification factors will be based on data available in the Highway Safety Manual as applicable <br /> • Up to five scenarios will be evaluated in the DTA model for the first level screening <br /> • Up to ten alternatives will be evaluated in the Synchro model for the first level screening <br /> • Proposed roundabouts will be modeled using Sidra <br /> • Up to five alternatives will be evaluated in VISSIM for the second level screening <br /> • Up to two interim year volume forecasts will be calculated (2030 and 2040) <br /> • Up to five phases of the preferred alternative will be modeled in VISSIM <br /> Deliverables <br /> • Tabular and graphical summary of model output <br /> • Electronic model files of each alternative <br /> • Draft and Final traffic analysis section of the final report <br /> Transit <br /> Approach <br /> The consultant will identify transit routing,frequency alternatives,and infrastructure investments to improve <br /> operational performance to and through Everett.Transit alternatives will be identified based on the results of the <br /> ridership modeling and operational performance analysis, planned transit service and infrastructure, and forecast <br /> ridership demand. <br /> Assumptions <br /> • Up to 10 transit alternatives will be evaluated in the first level screening <br /> • Up to 5 transit alternatives will be evaluated in the second level screening <br /> • Only conceptual level engineering with be completed <br /> Deliverables <br /> • Draft and Final transit inventory section of the final report <br /> Active Transportation <br /> Approach <br /> The consultant will identify active transportation alternatives to improve access and mobility on local streets and <br /> connecting roadways to the interchange as well as alternatives across the trestle.Active transportation <br /> 5541844828 <br /> City of Everett July 2021 <br /> U5 2/I-5 Interchange Planning Study 23 <br />
