(Reporter 50, Apr 2004) New Jersey Department of
Transport (DOT) is replacing
a traffic circle at a heavy
traffic intersection of State
routes 30 and 130. A professional
engineering design
and consulting firm hired
Medina Consultants, P.C. to
provide accurate crosssections
and a digital terrain
model (DTM) of the existing
four and six-lane roadway.
The contract was awarded
based on conventional and
aerial survey techniques.
After winning the bid,
Medina Consultants agreed
to use their Cyrax® 2500
(since rebranded as
HDS2500) for the project.
The Cyrax system could save
$24,000 budgeted for lane
closure costs and halve
survey labor to five days
with a four-person crew from
20 days with a two-person
crew. In addition, operators
would not be at risk in traffic
lanes and drivers would not
be aggravated by closing
lanes.
