Frequently Asked Questions - Aurora Avenue Business Access and Transit (BAT) Lanes and Transit Signal Priority (TSP)

  1. Why is it recommended that parking restrictions be implemented for both directions during the AM and PM peak periods?

    Parking restrictions are proposed to be in effect for both northbound and southbound directions during the AM and PM peak periods so that BAT lanes can provide maximum benefit for Metro’s RapidRide E Line bus service.  Maintaining speed and reliability is extremely important for attracting and retaining transit riders.  Most northbound buses on Aurora turn around and become southbound buses (and vice versa).  Operating BAT lanes in both directions will help keep buses arriving on time. In Shoreline and south of the Aurora Bridge, Aurora BAT lanes are in effect 24 hours per day, 7 days per week.

  2. Will there be traffic diversion onto other streets if the recommendations are implemented?

    Implementing traffic signal optimization, transit signal priority and the extension and completion of the existing BAT lanes may cause some traffic from Aurora Avenue to divert to alternative travel routes during the peak hours.  Travel routes that may be affected during peak commute times include Interstate 5, Greenwood/Phinney Avenue North and 15th Avenue NW.  In anticipation of the potential for peak hour traffic diversion, SDOT will make adjustments to traffic signals to accommodate changes and fluctuations in traffic volumes on Aurora as well as these alternative routes.  The proposed project will improve transit travel time through the corridor while maintaining or improving peak hour travel times for non-transit modes.

  3. Why is SDOT evaluating the section between N. 77th Street and N. 72nd Street rather than moving forward with consistent BAT lanes through the area?

    Under the proposed schedule, in fall 2013 SDOT will evaluate the benefits of southbound PM BAT lane implementation on Aurora Avenue between N. 77th Street and N. 72nd Street, where parking options are limited.  During this period SDOT will also work with local businesses to address their parking needs in light of the proposed parking restrictions.  If warranted by the results of the evaluation, SDOT will implement the recommendation in February 2014.

  4. Will the BAT lanes also be used as HOV (High Occupancy Vehicle) lanes?

    To avoid confusion on the part of drivers traveling to and from Shoreline, where well established BAT lanes are for buses and right-turning vehicles only, SDOT is not recommending that the Aurora BAT lanes double as HOV lanes.  Aurora Avenue is prioritized for transit and allowing HOV users may hinder transit operations.

  5. What is the current transit ridership for Metro Route 358 which will become RapidRide E Line?

    Metro Route 358, which will be replaced by RapidRide E line carries more riders than any other Metro route.
