Google Road View has quick turn out to be a software for individuals attempting to get the texture for a group, take a look at actual property – and generally prank the tech big when its mapping automotive drives by. Nevertheless it additionally has the potential to assist forestall falls and accidents in New Zealand’s city environments.
Falls are a number one reason behind harm and unintentional dying amongst older adults, however figuring out the situation of dangers exterior is labour and time intensive.
In our new analysisnow we have created a software utilizing Google Road View to audit the locations the place individuals stroll.
The objective of our new software – Fall-SAFE – is to establish the dangers in New Zealand’s constructed environments and create a database for native councils and group teams to know the place an older particular person may fall – and why.
A pricey danger
Yearly, one-in-three individuals over 65 are injured in a fall. This determine rises to one-in-two for individuals over 80.
In 2023 alone, ACC acquired 236,985 new claims for falls from individuals over the age of 60. Many of those falls resulted in severe harm, comparable to a hip fracture, hospitalisation and even dying.
It’s not simply older people who find themselves prone to falling – although they’re, by far, the most important group. Final yr, ACC paid out NZ$2.15 billion to cowl claims for falls.
The flow-on impact from falls extends additional than simply medical restoration. Older individuals who have fallen exterior, or who worry falling resulting from perceived dangers, could also be much less keen to go for walks. They then miss out on the bodily, psychological and social advantages of this kind of exercise.

Assessing the setting
Utilizing knowledge from ambulance service Hato Hone St Johnwe recognized 2,117 falls between July 2016 and June 2018 in city areas involving adults aged 65 and over. Wellington was excluded as the town makes use of a unique ambulance service.
Auditors then used Google Road View to evaluate the places of those falls and establish dangers within the constructed setting which may have contributed. These dangers included journey hazards, uneven foot paths, obstructions (comparable to overgrown bushes) and slopes.
Auditors used a “drop-and-spin” strategy to their evaluation, the place they accomplished a 360° audit of the autumn location. The Google Maps imagery was set to be as near the date of the accident as doable.
Drop-and-spin digital audits are faster than bodily audits, however equally dependable. Moreover, drop-and-spin digital audits allow evaluation over giant geographic areas that will be troublesome to look at in particular person.
Understanding New Zealand’s streets
After analyzing the totally different fall websites, we gained a greater understanding of the place falls occurred and the hazards that would have contributed to the falls.
Half of all of the falls had occurred in residential places (49.1%) and one quarter occurred in industrial places (22.4%). An additional 16.2% of the falls had occurred in “different” places (comparable to rural or industrial areas).
Over 60% of fall websites had at the very least one journey hazard resulting from poorly maintained footpaths. The most typical obstructions had been manholes, service covers or grates (71.5 %), poles (65.4%), utility containers (46.6%) and overhanging vegetation (39.5%). Different obstructions comparable to bus shelters, chairs and tables, or drains had been famous at 64.5% of the websites.
Three-quarters of the falls had occurred in places that had a flat or mild slope (76.3%). Solely 15.5% of the falls had occurred on a average slope, whereas 8.2% had occurred on a steep slope.
Most (95.6%) of the autumn places had a standard kerb peak (ten centimetres). Few places had no kerbs (2.3%) or storm drains (2%). Streetlights had been current in most fall places, both on one aspect of the road (together with partial or very sparse places) (54%) or on either side (44%). Streetlights weren’t seen in 0.9% of websites.
Of all of the places we assessed, just below 6% had no apparent danger in any way. This appears to point that exterior hazards had been a contributing issue to the overwhelming majority of falls – although with out data from the one that fell, it’s onerous to know for positive.
A less expensive and quicker possibility
The present strategy to assessing the security of city environments – sending individuals out to bodily take a look at a footpath to establish points – may be time consuming and expensive.
And the cash to do the work is solely unavailable. A number of councils, together with Hamilton and Mastertonhave introduced important cuts in funding from the New Zealand Transport Company to keep up and restore footpaths and cycle lanes.
One other drawback is that these assessors could not totally perceive the experiences of older individuals in these places. A hazard for somebody aged 65+ could not appear to be one for somebody of their 30s or 40s.
Understanding the elements that contribute to a fall for older individuals – comparable to obstructions and journey hazards – permits metropolis planners to handle issues within the constructed setting.
Our free auditing software gives a method for councils and advocacy teams to have a look at environments to know the dangers. Our analysis utilized this to locations the place we all know individuals had fallen, however the software can be utilized to evaluate the danger of any setting.
Investing the effort and time now to handle these fall dangers early might get monetary savings – and lives – additional down the monitor.
