Ford has announced the development of a road safety tool that can predict traffic incident locations based on data from connected vehicles, roadside sensors and accident reports.
Developed alongside a consortium co-funded by the UK’s innovation agency Innovate UK, Ford’s new RoadSafe concept has been developed to help alert drivers to higher risk locations and make insights of this kind available to local authorities.
Universally applicable and scalable for areas ranging from large cities to small towns, the technology uses a smart algorithm to crunch anonymised data from sources including connected vehicles, roadside sensors and accident reports in order to pinpoint where there is a higher chance of traffic incidents occurring. This information can then be displayed on a map that identifies the level of risk and could also be used to warn drivers of hotspots.
Jon Scott, project lead, city insights, Ford Mobility, Europe, said: “There are areas in every city where the chance of an incident is higher, whether it’s due to a poorly placed sign, an unrepaired pothole or junctions built to accommodate far less traffic than we have today. Now, Ford can pinpoint the areas of concern, so drivers could be made more aware of them and authorities can address them.”
The RoadSafe digital tool is the culmination of four years of research by Ford, including most recently a 20-month UK government-funded project conducted together with Oxfordshire County Council, Loughborough University and AI sensor specialist Vivacity Labs, with support from Transport for London and backing from Innovate UK.
The research began with an analysis of Greater London to highlight road safety hotspots and to identify the potential causes and safety mitigations. In the last 15 months, the research expanded to Oxfordshire, with more than 200 passenger and commercial vehicles voluntarily connected in London and Oxfordshire. The data enabled the team to develop a ‘Road Segment Risk Rating Heat Map’ that identifies stretches of road that are of particular concern.
This dashboard includes various layers of data, including historic accident data and a ‘Risk Prediction’ rating algorithm for each road segment based on a range of data inputs, calculated using advanced data analytics techniques. The rating uses colours to show where incidents are more likely to happen, with red having the highest risk level and yellow the lowest.
To gather the data, the connected vehicles record driving events, including braking, steering and accelerating, while Vivacity’s road-side sensors track the movements of different modes of transport. The sensors employ machine-learning algorithms to detect near-miss incidents and are able to analyse movement patterns of vulnerable road-users such as cyclists and pedestrians, as well as non-connected vehicles. All data shared by the sensors is anonymised with video feeds discarded at source.
According to Ford, combining vehicle and sensor data can help identify a wide variety of hazards such as places where vehicles pass too close to cyclists; a poorly located bus stop causing traffic to become congested; and badly designed infrastructure such as a roundabouts and junctions causing confusion and near-misses.
