The length of vehicle queues waiting to enter the intersection— <br /> while related to delay—is not explicitly considered in calculating LOS. A separate inspection of observed/estimated <br /> queue length is required.Long vehicle queues have the potential to create problems typically by: <br /> ➢ Exceeding available storage <br /> ➢ Preventing turning vehicles from accessing turn lanes due while stuck in a through lane queue <br /> ➢ Increasing rear-end crashes due to unexpected queues especially around curves <br /> ➢ Increasing potential for blocked intersections(gridlock),driveways,crosswalks,and railroad tracks <br /> Several signalized intersections have potential long queueing issues: <br /> ➢ Buckhorn Road NB lane(Both peak hours)-only about 150' (-6 vehicles)from at-grade railroad crossing in PM. <br /> 63 US 70 Multimodal Corridor Study Existing Conditions Report <br />
