The ‘Congestion Avoidance Dynamic Routing Engine’ (CADRE) uses Artificial Intelligence (AI) to interpret live traffic information shared between vehicles fitted with a special GPS.
The project is part of a consortium, consisting of the University of Portsmouth, ComSine, Smartcom Software, the Transport Research Laboratory, ViaMichelin and Hampshire County Council.
CADRE can sense traffic slowing down and building up into jams and works by ‘monitoring’ other vehicles on the road, informing motorists 5 to 10 miles away of a situation as it’s happening and recommends steps to avoid it while they can.
The AI software is built around ‘fuzzy logic’ which mimics human reasoning. The capability comes from the University of Portsmouth’s Institute of Industrial Research (IIR) which specialises in using artificial intelligence techniques for industrial applications.
Dr David Brown, Head of the IIR, said: “The system interprets live data from current traffic conditions so the motorist receives up-to-the-minute advice and can make an informed choice. It’s designed to take the pain out of that agonising decision about whether to try an alternative route which could be equally congested.”
The system takes into account of how traffic speeds vary by day of the week and time of day and even on individual roads. It means that journey times are predicted more accurately and better routes are calculated that take account of the typical traffic conditions for the time of travel.
CADRE learns constantly from motorists’ incoming data and will adapt itself to long term and short term speed predictions and ever changing circumstances to continuously update and improve its knowledge.
“At present routing can be carried out for minimum time or distance, but this can easily be extended to other criteria such as minimum cost or minimum CO2 emissions,” said Dr Brown.
Over 2,100 journeys were made on routes around Hampshire including the M27, M3, A3 and the notorious M25 to provide data for analysis. Additional speed data came from the British Highways Agency data to form the background knowledge needed within the AI system.
Richard Walker is from the Transport Research Laboratory, formerly the research arm of the Department of Transport, who advised researchers on data sources and the best methods of testing. He said: “The transport system in the UK is one of the key drivers of the economy and with more and more cars on the roads; a system like CADRE would be a valuable tool in keeping traffic moving.”
Future plans for the system would extend it to ferries, trains and even planes allowing travellers to examine different departure times to estimate the best time and route to travel. CADRE could be in the shops in as little as 18 months.
The University of Portsmouth’s technical partners, ComSine and Smartcom Software, both specialise in developing software and systems for the mobile communications, navigation and geographic information markets.
The project was sponsored by the South East of England Development Agency (SEEDA) as part of its role in the Government’s Innovation Platform in Intelligent Transport Systems.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
