Section 6F.70 - Temporary Traffic Barriers as Channelizing Devices

01 Temporary traffic barriers are not TTC devices in themselves; however, when placed in a position identical to a line of channelizing devices and marked and/or equipped with appropriate channelization features to provide guidance and warning both day and night, they serve as TTC devices.

Standard:

02 Temporary traffic barriers serving as TTC devices shall comply with requirements for such devices as set forth throughout Part 6.

03 Temporary traffic barriers (see Section 6F.85) shall not be used solely to channelize road users, but also to protect the work space. If used to channelize vehicular traffic, the temporary traffic barrier shall be supplemented with delineation, pavement markings, or channelizing devices for improved daytime and nighttime visibility.

Guidance:

04 Temporary traffic barriers should not be used for a merging taper except in low-speed urban areas.

05 When it is necessary to use a temporary traffic barrier for a merging taper in low-speed urban areas or for a constricted/restricted TTC zone, the taper length should be designed to optimize road user operations considering the available geometric conditions.

Standard:

06 When it is necessary to use a temporary traffic barrier for a merging taper in low-speed urban areas or for a constricted/restricted TTC zone, the taper shall be delineated.

Guidance:

07 When used for channelization, temporary traffic barriers should be of a light color for increased visibility.
