    Ford technology can help reduce Phantom Traffic Jams

    • Phantom traffic jams occur when drivers ahead tap their brakes – setting off a chain reaction that results in traffic behind grinding to a halt

    • Phenomenon is exacerbated during the summer holiday season when families across Europe head for the roads in abundance

    • Ford and researchers show that widespread use of Adaptive Cruise Control tech offered on Ford models from Fiesta to Transit van can mitigate and even prevent phantom jams

    As schools close for the summer, and people take to the roads to begin their summer vacations, congestion can quickly build on some of the UK’s more popular routes. On busy roads so called ‘phantom’ traffic jams can occur, when, seemingly without reason, traffic comes to a standstill.

    These frustrating jams are easily caused by human factors – such as merging into traffic without signalling, distracted driving, poor driving habits and reaction times, or unnecessary braking. Once one driver hits the brakes, a chain reaction can occur as other drivers tap their brakes, causing the flow of traffic to grind to a halt.

    Now, Ford and researchers from Vanderbilt University, a private research university in Tennessee, U.S., have demonstrated that such hold-ups could be minimised with widespread use of technology already offered on Ford vehicles from the Fiesta small car to the Transit van.

    Adaptive Cruise Control (ACC) technology can automatically slow down and speed up to keep pace with the car in front without getting fatigued or distracted.

    “A fun summer holiday family road trip can quickly become irritating when traffic slows to a crawl – especially once you learn there was no reason for the gridlock,” said Torsten Wey, manager, Driver Assistance and Safety Technology, Ford of Europe. “We encourage Ford owners who have Adaptive Cruise Control to use it during their summer travels in the hope this smart technology today can be that first step to help ease commutes.”

    On a closed Ford test track, 36 drivers simulated normal highway traffic using ACC technology. Those drivers then drove the same course, but without the technology – meaning they had to manually brake and accelerate the vehicle.

    The results: vehicles using ACC reduced the impact of a braking event more than those vehicles without the activated technology. Even with just one in three vehicles using ACC, the test yielded similar traffic-busting benefits.

    “For years, traffic researchers and engineers have been looking to smart vehicle technologies to reduce traffic congestion, whether that’s vehicles that talk to each other or vehicles that can predict the road ahead,” said Daniel Work, civil engineering professor at Vanderbilt University. “This demonstration was a unique opportunity to understand how commercially-available active driver-assist technologies can be used to positively influence traffic flow.”

    Ford currently offers Adaptive Cruise Control on 80 per cent of the company’s passenger and commercial vehicle line-up in Europe, and with the all-new Ford Focus recently introduced an enhanced version of the technology featuring Stop & Go, Speed Sign Recognition and Lane-Centring functionality for effortlessly negotiating stop-start traffic.

    A previous EU-funded joint research project led from the Ford Research and Innovation Center, Aachen, Germany, concluded that vehicles equipped with ACC and Forward Collision Warning technology could help prevent or mitigate the effects of more than 5 per cent of motorway accidents resulting in injuries; save drivers more than 3 million hours per year stuck in traffic; and reduce passenger car fuel consumption by 3 per cent.
