A traffic control marker is provided and described herein. The traffic control marker can be configured with a main marker body that is flexible and durable, the main marker body can be further configured with a reflective element that covers at least a portion of the main marker body. The main marker body can further be configured with an indentation or a channel that extends a portion of or alternatively the length of the main marker body. The reflective element is configured to be protected during a vehicle impact with the traffic control marker, such that at least a portion of the reflective element remains effective and reflective after the impact.

A device includes a cone having a cone first end with a flange, the cone extending to a cone second end. A base has a recess to mate with the flange of the cone. The base also has multiple base openings. A ring is shaped to fit on top of the flange and has multiple ring openings to mate with the base openings in a top of the base for releasably coupling the cone to the base.

A two-layer retroreflective article construction is enabled that produces higher wide-entrance-angle performance for signs and pavement markings. A single-layer overlay is enabled for existing signs and pavement markers that improve their entrance angle performance. Materials used in the construction of an article or an overlay are transparent to radiation in the range of 400 to 1000 nanometers and utilize TIR (total internal reflection). Minimum performance specifications are proposed that extend sign sheeting retroreflectivity specifications to entrance angles of 60 degrees. An innovative traffic sign design is enabled that increases the positioning performance of safety systems and automated navigation systems.

Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, system for an autonomous vehicle includes one or more signaling devices configured to visually notify other vehicles when placed on or near a roadway, and an object placing device configured to place the one or more signaling devices. The system further includes a processor and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: determine that the autonomous vehicle has experienced a malfunction, and provide instructions to the object placing device to place the one or more signaling devices on or near the roadway.

A retroreflective sheet 9 of the present invention includes; a surface layer 1; a glass bead holding layer 5 containing glass beads 3 that are located randomly as viewed cross-sectionally; and a metal reflective layer 4 on a back surface side of the glass bead holding layer 5. The surface layer 1 is a vinyl chloride resin layer. The retroreflective sheet further includes, between the vinyl chloride resin layer and the glass bead holding layer, a barrier layer 2 for preventing deterioration of the metal reflective layer. The barrier layer 2 is preferably an alkyd-melamine resin layer. Thereby, it is possible to provide a retroreflective sheet that can prevent the degradation of, e.g., the reflective function of the metal reflective layer on the back surface side of the glass bead holding layer and thus maintaining high weather resistance and wide-angle reflectivity, and that can exhibit high surface printability.

The rotating reflective sign for use with a disabled vehicle comprises a mounting base, a telescoping armature, a sign, and an information pouch. The rotating reflective sign for use with a disabled vehicle may be removably coupled to a vehicle and may be adapted to alert oncoming motorists that the vehicle is disabled and/or unattended. The mounting base may couple to a top surface of the vehicle. The telescoping armature may extend upwards from the mounting base and may support the sign above the vehicle. The sign may rotate when actuated by wind. The sign may comprise a plurality of vanes that may reflect light and may thereby increase the visibility of the sign. The information pouch may be adapted to provide information regarding an owner of the vehicle.
