Iowa DOT to use new Inrix Safety Alerts to help prevent rear-end collisions

7511 Iowa Department of Transportation (DOT) has renewed its traffic data services contract with 163 Inrix and will also employ Inrix Dangerous Slowdowns, a newly launched service that warns drivers and DOTs of sudden reductions in speed or stopped traffic on the road.


Dangerous Slowdowns is part of the new Inrix Safety Alerts product suite which also includes Inrix Incidents and Inrix Road Weather, to provide real-time insight on roadways to inform drivers and make roadways safer.

The Safety Alerts product suite collects real-time data from vehicles and range of other sources to help drivers around the world avoid sudden stops, accidents and hazardous road condition, and aids transportation agencies in managing their road networks.

Inrix Dangerous Slowdowns is a service in Inrix XD Traffic that helps prevent back-of-queue, rear-end collisions. Based on real-time data from vehicles on the road, the location-based notifications warn drivers and transportation agencies of sudden reductions in speed or stopped traffic on the roadway.

Inrix Incidents uses more than 400 data sources to keep drivers and transportation planners informed about congestion, accidents and construction on the road.

INRIX Road Weather uses real-time and predictive atmospheric data to give drivers and transportation officials advance warning of dangerous weather-related road conditions tied to individual road segments, providing information about the roads themselves, including the type of precipitation, surface condition and visibility.

    Wrong-way driving (WWD) is a remarkably innocuous term for incidents that all too often cause some of the worst accidents that emergency services have to deal with. Several US states are now taking steps to minimise the problem, as Alan Dron finds out. You’re driving down a highway at night when you see approaching headlights. You initially assume they are merely those of an oncoming car on the opposite carriageway. It’s only when they are within 200 yards or so that you realise that the other driver is in

    David Crawford investigates progress in a key safety area - work zones. Highway construction zone safety is taken seriously enough in the US to merit a special spring National Work Zone Awareness Week, which in 2010 ran from 19-23 April. Headed by the US Department of Transportation's Federal Highway Administration (FHWA), this aims to reduce an annual toll of work zone deaths - 720 in 2008 (an average of one every 10 hours) with more than 40,000 traffic injuries (an average of one every 13 minutes).

    The German AKTIV project is researching several cooperative driving applications for use in work zones. PTV's Michael Ortgiese details progress. The steep increases in traffic volumes predicted back in the early 1990s have unfortunately been proven to be more than accurate. In Germany, the AKTIV project continues to look into cooperative technologies' potential to reduce the impact of those increased traffic volumes and keep traffic moving despite limitations in infrastructure capacity.
