BEST PRACTICE:

J3−1: Automated Machine for Cone Placement and Retrieval

DESCRIPTION:

The California Department of Transportation (Caltrans) developed and tested a machine that will mechanically place and retrieve cones, thus reducing maintenance personnel exposure to the hazards of traffic and physical exertion involved in handling the cones. The Automated Cone Machine uses robotics, automation, and advanced computer control to place and retrieve cones around highway work zones. The development of the machine was conducted by the Advanced Highway Maintenance and Construction Technology Center (AHMCT) (http://ahmct.ucdavis.edu/), which is jointly managed by the University of California, Davis and Caltrans.

REASON(S) FOR ADOPTING:

Deployment of cones is currently achieved by a person riding on the exterior of a modified vehicle. This process requires a considerable amount of manual effort and personnel are exposed to the hazards of traffic in addition to the physical exertion involved in handling the cones.

PRIMARY BENEFIT(S):

Benefits are expected in improved safety and operational efficiency. The advanced cone machine removes the need for a worker riding in the rear area of the truck.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Roadway maintenance on all freeways and for any work zones requiring placement and collection of traffic cones.

STATE(S) WHERE USED:

California
