Hydro unveils rotating mast arm for traffic signals
Hydro Pole Products is launching a rotating mast arm which says will improve safety for operators responsible for maintaining traffic signals on multi-lane carriageways.
Operators can control the rotating mechanism by using an internal winch located in a separate door compartment at ground level.
The aluminium solution can either be installed in the ground or via the retention socket with anti-rotation design.
Testing robo cones for work zone safety
Robotic self-wheeling traffic cones and smart rumble strips will be trialled on CityLink to help boost safety for people working in live traffic.
Remote-controlled robotic traffic cones will be tested and if successful would remove the need for road workers to manually place or move cones when setting up or taking down road works or emergency zones in live traffic.
Sensors will also be used on traffic cones and rumble strips to test the ability to communicate in real-time with workers via a wearable device such as a vest, which would light up, vibrate and sound an alarm when a vehicle enters the worksite, so they can get out of danger.

Three Small Stickers in Intersection Can Cause Tesla Autopilot to Swerve Into Wrong Lane
Security researchers from Tencent have demonstrated a way to use physical attacks to spoof Tesla's autopilot
An integral part of the autopilot system in Tesla's cars is a deep neural network that identifies lane markings in camera images. Neural networks "see" things much differently than we do, and it's not always obvious why, even to the people that create and train them.
Because of this disconnect between what lane markings actually are and what a neural network thinks they are, even highly accurate neural networks can be tricked through "adversarial" images, which are carefully constructed to exploit this kind of pattern recognition.
