Front crash prevention slashes police-reported rear-end crashes, says IIHS

Vehicles equipped with front crash prevention are much less likely to rear-end other vehicles, the Insurance Institute for Highway Safety (IIHS) has found in the first study of the feature's effectiveness using US police-reported crash data. The study found that systems with automatic braking reduce rear-end crashes by about 40 per cent on average, while forward collision warning alone cuts them by 23 per cent. The automatic braking systems also greatly reduce injury crashes.

Vehicles equipped with front crash prevention are much less likely to rear-end other vehicles, the 7120 Insurance Institute for Highway Safety (IIHS) has found in the first study of the feature's effectiveness using US police-reported crash data.

The study found that systems with automatic braking reduce rear-end crashes by about 40 per cent on average, while forward collision warning alone cuts them by 23 per cent. The automatic braking systems also greatly reduce injury crashes.

"The success of front crash prevention represents a big step toward safer roads," says David Zuby, IIHS chief research officer. "As this technology becomes more widespread, we can expect to see noticeably fewer rear-end crashes. The same goes for the whiplash injuries that often result from these crashes and can cause a lot of pain and lost productivity."

Using police reports allows researchers to identify front-to-rear crashes in order to gauge front crash prevention systems' effectiveness specifically for the type of collision they are designed to address.

For the study, researchers looked at police-reported rear-end crashes in 22 states during 2010-14 involving Acura, Honda, Mercedes-Benz, Subaru and Volvo vehicles with optional front crash prevention. The crash rates of vehicles equipped with the technology were compared with the crash rates of the same models without front crash prevention.

Individual vehicles with the technology were identified using trim level information or, in some cases, lists of vehicle identification numbers supplied by the manufacturers.

Front crash prevention is steadily becoming more prevalent, but in most cases it is offered as optional equipment. That may soon change, however. In September, the 834 National Highway Traffic Safety Administration and IIHS announced an agreement in principle with automakers to make automatic braking standard on all models.

    The European Commission has adopted two proposals to ensure that, from October 2015, all new models of passenger cars and light duty vehicles will have to be fitted with 112 eCall, enabling them to automatically call emergency services in case of a serious crash. eCall is activated automatically as soon as in-vehicle sensors detect a serious crash. Once set off, the system dials the European emergency number 112, establishes a telephone link to the appropriate emergency call centre and sends details of the

    The type-approval of roadside drug testing equipment could bring about fundamental changes to the way police tackle the problem as Colin Sowman finds out. It has been almost 50 years since the first drink-driving laws were introduced but the problem persists: the European Commission estimates that 25% of road fatalities in the EU are the result of alcohol consumption. Statistics from the UK show that 20% of drivers killed in road accidents in 2012 were over the blood alcohol limit for driving.

Eighty per cent of all the UK speed cameras investigated had hard braking activity, with braking increasing six fold on average at these loca
