Agenda - Public Works Committee - 12/18/2018

Name: Bruce Westby, P.E. Date: December 5, 2018 Page: 2 of 2 It is not recommended, due to safety considerations, that Rabbit Street be STOP or YIELD controlled and Bunker Lake Boulevard and Puma Street be uncontrolled. If neither Bunker Lake Boulevard or Puma Street had either STOP signs or YIELD signs, both the westbound vehicle and the southbound left/right turning vehicles would technically have the right-of-way. Each could proceed with their movement, and meet in the intersection. INTERSECTION CONTROL PROGRESSION For the 2040 traffic volumes, either a roundabout or an All Way STOP provide high Levels of Service for the intersection. There is the potential for interim intersection traffic control to be implemented based on actual site and traffic characteristics. If adjustments were made, the progression would most likely be: YIELD sign for southbound Puma Street, · Then STOP sign for southbound Puma Street, and · Then All Way STOP at the intersection. · INTERSECTION ANALYSIS The existing intersection control was selected based upon several factors, including: State Aid requirements, traffic forecasts, safety and anticipated traffic patterns. The selection was based on a traffic study that was completed prior to the reconstruction of Bunker Lake Boulevard and Puma Street and prior to the construction of Rabbit Street. If the City is considering adjustments, the following guidance from the MUTCD should be considered when preparing an updated traffic study based upon the actual improved site conditions: Engineering judgment should be used to establish inter-section control. The following factors should be considered: A. Vehicular, bicycle, and pedestrian traffic volumes on all approaches; B. Number and angle of approaches; C. Approach speeds; D. Sight distance available on each approach; and E. Reported crash experience.
