Advanced driver assistance systems (ADAS), a computer-aided means of keeping a vehicle in its lane and preventing or mitigating collisions, is a relatively new concept in the automotive world and even newer for the trucking world.

 

On the truck side, they are also commonly referred to as CMS or Collision Mitigation Systems.

 

No matter what you call it, truck fleet managers, fleet owners and fleet safety departments are already sold on the concept. In fact, according to Brian Daniels, manager of Power Train and Component Product Marketing for Daimler Trucks North America, makers of Freightliner and Western Star trucks, 75 percent of the new trucks coming off their lines now have integrated CMS systems. Unlike the auto side, collision mitigation systems can also be retrofitted to older trucks.

 

At its semi-annual meeting and exhibition, on March 19, the Technology and Maintenance Council (TMC) conducted a panel discussion titled “Justifying, Implementing and Maintaining Active Safety Systems.”

 

The room held perhaps 750 people and had standing room only. Featured speakers were:

 

Chris Reynolds – Southeastern Freightlines (large fleet operator)
Rick Reinoehl – Covenant Transportation (large fleet operator)
Brad Aller – Bendix Systems safety systems (producer of ADAS systems)
Doug Donaldson – WABCO Americas safety systems (producer of ADAS systems)
Brian Daniels – Daimler Trucks (makers of Freightliner and Western Star trucks and Detroit diesel engines)

 

The Good

 

Chris Reynolds, director of safety and security for Southeastern Freightlines noted that at first, he wasn’t entirely sold on the CMS concept. To test it, Southeastern retrofitted CMS systems in 10 over-the-road trucks and monitored them for six months. The result was a drastic reduction in accidents. Roll-over accidents were decreased by 40 percent, run-off-the-road accidents were decreased by 14 percent, and rear-end collisions were decreased by 22 percent.

 

For 2018, one fleet manager noted 2.61 accidents occurred per million miles driven for those tractors without CMS technology. An average for all tractors was 2.03. But for those tractors with CMS technology, the accident rate went down to 1.05.

 

Accident rates are sure to go down looking forward. In 2014, less than 30 percent of heavy trucks utilized a CMS system. In 2018, that’s up to almost 75 percent.
