June 2017 – LidarCrawl software helps Caltrans District 4 geospatial data management

AHMCT researchers recently developed and deployed software tools for automated Mobile Terrestrial Laser Scanning (MTLS) data cataloging. These tools are currently in use in Caltrans District 4 in Oakland. The tools enhance Caltrans’ ability to determine MTLS data availability using a web browers or GIS tools. District 4 has about 50 TB of MTLS data. The storage, management, and organization of this data had become both critical and challenging. The new tools support District 4 in their upgrade and enhancement efforts for MTLS data management and for mining geospatial data from existing MTLS data foruse by District 4 Surveys’ customers throughout District 4 and its partners such as the local Metropolitan Planning Organization (MPO).

May 2017 – The Sealzall system stirs up interest at the Caltrans
District 8 Innovation Fair

Caltrans District 8 recently hosted its Innovation Fair. Al Herrera, a
maintenance supervisor level II from District 11, presented his findings
for the Sealzall system. This system supports both longitudinal and
random crack sealing with increased efficiency. It is particularly
effective for longitudinal sealing, where one operator can seal cracks
at a continuous 2 – 5 mph in a moving lane closure, all from the safety
of the truck cab. Mr. Herrera and his crew have field tested the
Sealzall system for more than a year, and have been very pleased with
the system and the capabilities it provides them. The Sealzall sealant
kettle heat-up and sealing systems are fully automated and can be
monitored and controlled from inside the truck’s cab. Caltrans workers
are not on foot or exposed to direct highway traffic while on the
highway. Using the Sealzall, Caltrans has consistently sealed 5-8 linear
miles of edge joints a day, and the Sealzall machine can be utilized to
yield up to $4.0 million dollars in cost savings annually. Based on Al
Herrera’s presentation and discussions at the Innovation Fair, District
8 is now planning to use the system late in the summer of 2017.

May 2017 – Mountain Pass Road Opening (MPRO) is a hit on State Route 120 Tioga Pass

After the most significant winter snowfalls in many years, Tioga Pass
was buried in snowdrifts from 15 to 50 feet deep over several miles by
April 2016. Caltrans Maintenance must open this pass before summer. This
is a very hazardous task, with State Route (SR) 120 right next to a
steep drop-off. Maintenance workers need to keep their vehicles over the
roadway while removing massive amounts of snow, but they have no visual
indications for the road location when the snow is this deep. The MPRO
system uses GPS and an in-vehicle display, along with a highly accurate
base map, to show the vehicle operator where they are currently at
relative to the road. With AHMCT’s MPRO system, one maintenance worker
can begin cutting the snow at the right location, and the other
operators can use this accurate cut as a visual guideline. Using the
MPRO system, Caltrans operators are opening Tioga Pass in May more
efficiently and far more safely. The supervisor said they were not only
using the MPRO system, but they “love it”!
