Ford Mobility in Europe has revealed insight into where and why some road stretches are more likely to experience safety incidents than others.
The insights come from the latest part of a two-year study into how connected vehicles and big data analytics can help make travelling in cities easier and safer.
According to Ford, “relatively simple” improvements to roads and junctions could help address safety issues identified at major traffic incident hot-spots across London, UK.
“Using data to identify where safety incidents are most likely to occur is one thing – proving the concept works is another,” said Jon Scott, project lead, City Insights, Ford Mobility, Europe.
“We have now taken the innovative predictive road safety concept we introduced last year one step further by engaging with civil engineering experts to better understand the reasons behind safety incidents at these locations and make suggestions on how to address them.”
Mobility experts from Ford’s City Insights team revealed last year how near-miss event data, identified by indicators such as sharp braking or hazard light usage, collected from a year-long study of connected vehicles across London could – when correlated with historical accident data – be used to identify which stretches of road were most likely to experience a road safety incident in the future.
Now, to further prove the concept and better understand why certain stretches of road experience a proportionally higher number of safety incidents, Ford has been working with traffic management company Traffic Watch UK to capture and analyse road-user activity from eight of the highest-ranking safety hot-spots.
From this they were able to identify driver behaviours and road conditions that could be contributing to an increase in safety incidents at those locations. These included:
– Traffic signal jumping by drivers and cyclists
– Illegible road signs due to overgrown trees or incorrect orientation
– Poor road surface conditions, including sunken service covers
– Narrow lanes creating conflict between road users
Ford is now in the process of sharing recommendations from the research, which could help address the road safety concerns at each of the incident hot-spots, with relevant local authorities.
Suggestions include the introduction of red-light cameras to deter signal jumping, cutting back vegetation to ensure road signage is clearly visible, double-height signage and signals, resurfacing carriageways and raising service covers, and revising junction layout to allow for appropriate lane widths.
Ford believes that, in the future, connected vehicles and real-time analytics could mean that risks to road users’ safety could be identified and mitigated as they occur.
The safety impact of upcoming changes to the road network could also be better understood, with suggestions made in advance to identify and address potential road safety hot-spots as a result of the actions.
After the study in London, which collected more than 500 million data points from one million recorded miles of driving, Ford is now working with other cities to identify further opportunities for data-driven insights.
City Insights is working with Valencia, Spain, and Cologne, Germany, to expand its understanding of different city types, incorporating further technologies.
