Arizona DOT adds monitoring technology to state bridges

Arizona Department of Transportation (ADOT) engineers in Phoenix will get real-time information on the conditions of four interstate bridges in remote north-western Arizona thanks to technology funded by a US$768,000 Federal Highway Administration grant. To enhance safety and efficiency, ADOT will use the Accelerated Innovation Deployment Demonstration grant to add structural health monitoring systems to the Interstate 15 bridges, embedding sensors on the superstructures that record, analyze and share da

6576 Arizona Department of Transportation (ADOT) engineers in Phoenix will get real-time information on the conditions of four interstate bridges in remote north-western Arizona thanks to technology funded by a US$768,000 831 Federal Highway Administration grant.

To enhance safety and efficiency, ADOT will use the Accelerated Innovation Deployment Demonstration grant to add structural health monitoring systems to the Interstate 15 bridges, embedding sensors on the superstructures that record, analyze and share data.

The systems, which will be installed by this autumn, will help ADOT identify and address problems quickly and decide when the bridges will need major repairs or replacement. They also will help ADOT engineers determine when to conduct inspections, which are required at least every two years and involve lane restrictions.

“The technology made possible by this grant will enhance the safety of the travelling public and help inform Arizona’s investments along this vital corridor,” ADOT Director John Halikowski said.

    While initial cost of radar based detection may be higher than that traditional loops, lower maintenance costs more than balance the books. Following successful field tests, the US city of Greenville, North Carolina, has recently agreed a new policy of phasing in Wavetronix traffic sensor technology’s radar-based SmartSensor Matrix system across its signalised traffic intersections. City traffic engineer Rik DiCesare expects the incremental implementation to deliver benefits to both the city’s taxpayers an

    High-speed WIM moves onto the main highway
    High-speed weigh-in-motion is starting to make its mark on both sides of the Atlantic. As a transit country the Czech Republic experiences a large number of overloaded vehicles, which greatly increase highway maintenance costs. This prompted its Transport Ministry to trial an extension of the capabilities of the existing truck tolling system to allow the dynamic high-speed weighing of cargo vehicles. In effect the tolling enforcement gantries become weigh-in-motion (WIM) locations.
