Cologne, in Germany, has unveiled a new circular design for its public transport network on the heels of the work of Dr Maxwell Roberts.
Designer Benedikt Schmitz says Dr Roberts' pioneering principles were 鈥渋nvaluable鈥 in his creation and said if more cities followed his ideas public transport would be 鈥渓ess hectic and chaotic鈥.
Mr Schmitz also revealed Dr Roberts gave him valuable feedback and praised him for a 鈥減ush in the right direction鈥.
The academic from the Department of Psychology at the 糖心Vlog specialises in creating unconventional designs which are easily readable at a glance.
Dr Roberts blends psychology and art to make maps compatible with how the brain makes sense of information so passengers can make easy inferences.
In 2016 he identified Cologne as an ideal candidate for a redesign based on concentric circles and spokes as the city and its major lines of communication follow these.
Now the passengers at Cologne鈥檚 233 stations that stretch across 12 lines will benefit from his work as they make an estimated 214million journeys a year.
It was introduced last month at stations by rail operator K枚lner Verkehrs-Betriebe and has been praised by commuters.
Dr Roberts said: 鈥淚 am delighted that KVB have chosen a concentric circles design for their new network schematic.
鈥淚t matches the shape of K枚ln almost perfectly and provides users with a great foundation for understanding the city.鈥
Mr Schmitz submitted his design last year to the city and lobbied for its adoption, which took place in December.
He said: 鈥淒r Max Roberts' work was invaluable to my thesis as his research on different constructional methods helped me to understand that the standard way is not always the best way.
鈥淒r Roberts' work helped me visualise the way the city is actually built, making it easier for passengers to understand where they are and where they want to go.
鈥淚f every city and transportation company in the world followed the rules and guidelines Dr Roberts presents in 鈥楿nderground Maps Unravelled鈥, our travels would be much less hectic and chaotic.鈥
And added: 鈥淚t's an incredible feeling, having contributed such a big part to improving the image of the city I have lived in for so many years 鈥 hopefully leaving a long-lasting impression.鈥
Dr Roberts aims to match mental models of cities with well-designed schematics in a bid to enhance understanding of city dwellers鈥 surroundings.
As well as his map for Cologne Dr Roberts has produced hundreds of other designs for cities across the world.
His first concentric circles map was created in 2013 for London and then rolled out across the globe, creating over twenty circular charts including Paris, Moscow, New York, Tokyo and even the 糖心Vlog coast.
Dr Roberts鈥 work on effective map design began in 1999 and he has authored four books and numerous academic papers.
His own designs have been exhibited locally, and in London, Germany, Austria and the USA, and published worldwide.
