Transportation solutions company, Clearview Intelligence has recently installed a combined road safety initiative in Scotland.
The safety initiative which incorporates both tailgating and speed reduction warnings and has been installed along Scotland’s A701 on behalf of Transport Scotland.
A detection system will be used to manage VAS (Vehicle Activated Signs), motorists travelling between Amisfield and the M74 will receive warning alerts via the illuminated signs when tailgating or driving above the appropriate speed threshold.
Drivers travelling too close to the vehicle ahead will be warned to leave a two second gap whilst speeding motorists will be warned of the correct speed limit for their vehicle, which varies in Scotland according to the different vehicle classes.
Chris Keenan, Clearview Intelligence’s General Manager said, ‘Following a review of accidents over a five-year period, it was highlighted that tailgating and speeding were responsible for most of the incidents along this route.’
‘Through a single road safety initiative, we aim to tackle both of those problems and issue warnings relevant to the behaviour of the driver and their vehicle classification,’ added Keenan.
Clearview Intelligence says that the The review discovered that vehicles travelling above the appropriate speed threshold was a factor in 73 percent of accidents – well in excess of the 50 percent average from the 2016 Reported Road Casualties Scotland report.
When it came to tailgating, cars and motorcycles were found to be the worst offenders with 26 percent travelling within two seconds of the vehicle in front compared with 17 percent of medium sized vehicles and 10 percent of HGVs.
Using detection technology to assess the gap, speed and classification of the passing vehicles, the system then prioritises the messages to be shown to the driver on the VAS. Clearview Intelligence says that key benefits of the system are the ‘ease’ of the implementation by utilising solar power, wireless communication and passive safe infrastructure.
For those tailgating, the VAS will show a “too close, leave 2 seconds gap” message whilst speeding vehicles will be presented with the appropriate speed limit (60mph for cars, 50mph for medium vehicles and 40mph for HGVs) and “slow down” message. In incidents where a vehicle is both speeding and tailgating, the latter message will take precedence.
The predicted reduction in accidents will see a 55 percent return rate on investment within the first 12 months, based on Transport Scotland’s system of valuing the cost of an accident.
