For a one-lane, two-way taper, the recommended number of devices is six. This is based on standard traffic control guidelines which specify the need for a certain number of channelizing devices to effectively guide vehicles through the taper area while maintaining safety. The taper is used to transition traffic from a normal travel lane to a work zone or other condition, and having the correct number of devices ensures that drivers have clear guidance and adequate warning of the change in road conditions.

The configuration typically calls for devices to be placed starting from the edge of the taper and covering the length of the taper, allowing for proper spacing and visibility. This arrangement is critical not just for driver awareness but also for the safety of workers in the area. Proper taper setups improve traffic flow and help reduce confusion, which is important in maintaining road safety.
