Projects under safety

Benefit Allows first responders to provide information to get the right equipment and personnel dispatched to the site. This product will effectively utilize resources. AHMCT researchers are finalizing the third generation of the Responder system, a communication tool that integrates hardware, software, and communications to provide incident responders, particularly those in rural areas with sparse […]

AHMCT researchers have developed, deployed, and currently maintain several self-contained vision based sensor systems which autonomously monitor hazardous highway locations. These devices provide web-based access to both live video and recordings of past incidents trigged by configurable events. These sensors were originally developed to collect highway crash attenuator impact data and have been on-line monitoring vehicle traffic incidents for over a year and half. The monitoring device is an ideal tool for the collection of traffic incidence data which would be useful for the assessment and mitigation of hazardous highway locations

Benefit High accuracy, feature-rich point clouds obtained from within a vehicle moving at highway speed. Keeps surveyors safe as they are not exposed to traffic. Supports “survey on demand” by extracting desired features and attributes from the point cloud without the need to return to the field for measurements. AHMCT researchers are working with Caltrans […]

Outcome Deployment of tunnel mucker machine to Caltrans Maintenance operations. Benefit Increases both the safety and efficiency of culvert clearing operations   AHMCT tested and evaluated the MicroTraxx tunnel mucker  machine, a radio controlled track loader from ROHMAC, for cleaning culverts in Caltrans operations. Why We Are Pursuing This Research Increase effectiveness and efficiencies Reduce […]

AHMCT researchers developed a prototype machine with the main purpose of collecting garbage bags placed on the roadway by cleanup crews. The machine will attach to trucks in the Caltrans fleet and will be mountable on either side of the truck with minimal modifications and impact to the truck’s current functions. The reduced cost of using current trucks will allow multiple units to be purchased, simultaneously increasing productivity, reducing costs, and reducing worker exposure to traffic.

Two Caltrans workers have been killed recently while attempting to patch highway potholes. In an immediate response to mitigate this hazard, Caltrans Divisions of Research and Maintenance are supporting an AHMCT research effort to deploy innovative equipment to Caltrans Maintenance crews to dramatically reduce worker exposure when conducting highway patching operations.

The newest generation ALCS machine have extended capabilities and are no longer limited to longitudinal only crack sealing operations. Our current machine, called the Sealzall has been developed with a multi-purpose heated hose and manual wand assembly to enable this equipment to be quickly configured for any type of crack sealing operation on the highway.

AHMCT is researching the roadside maintenance work environment to identify cost-effective deployable improvements to methods, equipment, and processes that will lessen worker injuries, increase worker effectiveness and support Caltrans goals of safety and stewardship.

AHMCT researchers developed a prototype machine, a dexterous manipulator, attached on a commercially available vacuum truck. AHMCT is supporting the testing and evaluation of the Vacall ARDVAC machine in Caltrans operations.

AHMCT researchers developed a prototype machine that enables a single driver operator to place or retrieve a lane closure with up to 100 cones. Design of a high capacity machine for up to 300 cones was also developed. In 2005 the Traf-tech Corporation produced a commercial machine based on the AHMCT design. AHMCT is supporting the testing and evaluation of the Traf-tech machine in Caltrans operations.
