INNOVATION IN ROADS
For this USD 17. 5 million project, the Washington State Department of
Transportation ( WSDOT) constructed a roundabout at the SR-9/84th Street
N.E. (Getchell Road) intersection near Marysville to reduce the risk of collisions
and improve traffic flow. About 19,000 vehicles per day use this stretch of SR 9,
which was the site of 43 collisions between 2007 and 2012. WSDOT also built a
new traffic signal at the SR 9/32nd Street S.E. intersection.
Using MicroStation and Luxology’s rendering engine, WSDOT created
an animated simulation of the roundabout that clearly and effectively
communicated the design, which, in turn, helped the public better understand
the design intent and benefits. The integration of MicroStation’s visualization
tools enabled WSDO T to produce a realistic traffic simulation from information
produced in InRoads.
For this INR 5. 67 billion project, V R TECHNICHE Consultants is widening
a critical two-lane road to four lanes between the Jorabat and Shillong
sections of NH- 40 (kilometer 0 to kilometer 31). In this section of road, the
NH- 40 cuts across the Shillong Plateau, which is a rigid cratonic block that is
geodynamically restless and seismically sensitive.
Topography presented the main challenge in terms of site conditions and
code specifications: hairpin bends that would require cuttings to be toward
the hillsides and fillings to be toward the valley side. Using MicroStation and
MXROAD, V R TECHNICHE Consultants iterated the process, optimized the
design, and then checked it by publishing it on Google Earth, which saved time
by minimizing site visits.
