Ford, Vanderbilt study proposes traffic jam solution

RESTRICTIONS: Broadcast: NO USE JAPAN, NO USE TAIWAN Digital: NO USE JAPAN, NO USE TAIWAN
New research by Ford and Vanderbilt University may have a new solution to traffic jams.

So-called "phantom" traffic jams occur when a driver at the head of a pack of cars slows for an unknown reason. The halting action ripples to all following vehicles causing them to also slow or stop.

Ford and Vanderbilt University researchers recently tested Adaptive Cruise Control, ACC, as a means of dealing with phantom traffic jams This system monitors traffic flow and adjusts speed accordingly. Ford say no traffic jam occurred when ACC was switched on.

Another method of reducing congestion, according to CNET, is ramp metering. This system uses traffic signals to manage the flow of traffic while vehicles waiting on an on-ramp.

Some areas in Ontario, Canada use High Occupancy Toll (HOT) lanes to lessen congestion. Motorists there can pay a premium to access these lanes in high-traffic areas prone to congestion.

RUNDOWN SHOWS:
1. Depiction of "phantom traffic jams"
2. Depiction of adaptive cruise control
3. Depiction of road metering
4. Depiction of high occupancy toll lanes
