Vivacity’s AI-controlled junctions

Manchester is using AI-controlled traffic junctions from Vivacity to smooth the interaction between vehicles and the UK city’s increasing number of cyclists and pedestrians.

Thanks to an app from sensor manufacturer Kistler, documentation is easier and more practical

As more cyclists and pedestrians use junctions originally designed to prioritise cars and other vehicles, there is a need to look carefully at exactly who is using the roads and crossings and how they might most safely be able to move around.

“Since the pandemic, commuter trends and traffic hotspots have changed completely and cities need AI to help protect people no matter what mode of transport they take,” said Mark Nicholson, chief executive of Vivacity Labs. “Our vision is to help cities implement critical policies addressing safety, air quality, sustainable travel and congestion at a hyper-local level.”

Manchester’s programme - which won the Innovative Use of Technology award at the 2020 ITS (UK) Awards - uses sensors with inbuilt artificial intelligence (AI) to help Transport for Greater Manchester (TfGM) to anonymously identify different types of road users at selected junctions.

By knowing what modes of transportation are present at a junction, traffic signals can be altered to prioritise some modes of transportation over others, such as cyclists over pedestrians and vehicles.

The AI signal control system, which Vivacity says is the first of its kind, went live last year and now simultaneously controls three neighbouring junctions in the Blackfriars area of Salford.

Manchester’s project is part of a three-year Innovate UK programme that could see up to 20 junctions using the Vivacity system by the end of 2021.

    The future of connected fleet management has arrived in the shape of Hitachi’s excavator concept, LANDCROS One.

    It blends artificial intelligence and gamified ergonomics with autonomous and remote- operation capabilities.

    The concept introduces what Hitachi calls “phygital” controls and digital interfaces to create an intuitive operator environment. The design features a modular cab with intuitive ergonomics specifically geared to appeal to the next-generation workforce through gamifying operations and AI-assisted interfaces.

    Mike Dreznes, executive vice president at the International Road Federation (IRF) discusses road safety for work zone areas. Work zones around the world can create significant congestion and can cost society billions of dollars. Estimates in the United States alone include approximately 87,600 work zone crashes involving 37,500 injuries that result in 482 million lost hours, valued at approximately US$6.5 billion. When considering these numbers worldwide, it becomes clear that work zone safety and work zone
