Arizona, Texas and Utah receive money to improved connectivity and transportation

New system also institutes countermeasures such as flashing warning signals

PWD10 visibility sensors and RWS200 system make driving safer on wind-blown highway

Arizona pilot scheme to identify wrong-way vehicles has been a success

Arizona Department of Transportation (ADoT) has developed a system to tell drivers to slow down on part of Interstate 10 (I-10) where blowing dust reduces visibility.

The US National Transportation Safety Board (NTSB) has found that an Uber autonomous vehicle which killed Elaine Herzberg last year had software flaws. NTSB released a report which says the Volvo XC60’s autonomous system software classified the pedestrian as an unknown object and determined that an emergency braking manoeuvre was needed to mitigate the collision. Uber confirmed that emergency braking manoeuvres must be carried out manually and the system is not designed to alert the driver. Data

A US$3.7 million project by Arizona Department of Transportation (ADOT) to construct a thermal detection system to detect wrong-way vehicles and alert other drivers and law enforcement has been approved by the State Transportation Board. Once operational, the system will use thermal cameras, warning signs for wrong-way drivers and advisories for right-way drivers along a 15-mile stretch of I-17. In addition, the system will automatically focus highway cameras on the wrong-way vehicle and send automated aler

Arizona Department of Transportation (ADOT) is installing new in-road sensors along the state’s freeways to monitor traffic flow in an effort to reduce congestion. The sensors provide the data used to estimate the travel times that that are displayed on message boards above freeways. The data also helps ADOT and the Maricopa Association of Governments, the regional transportation-planning agency make decisions about future freeway improvements. Using electronic wires embedded in the road, the sensors have b

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

The Arizona Department of Transportation (ADOT) has selected Connect 202 Partners as the preferred developer for its first highway public-private partnership, the Loop 202 South Mountain Freeway. The consortium includes Fluor Enterprises, Granite Construction and Ames Construction, with Parsons Brinckerhoff as the lead designer. The South Mountain Freeway will be constructed with four lanes in each direction - three general-use lanes and one HOV lane - and includes modern features including rubberised
