Once fully operational, the new technology will help to control the flow of traffic between Mays Hill and Penrith, with a number of signals installed on several on-ramps, including at Reservoir Road.
Crews are also installing electronic message signs, traffic sensors and lane use signs along the motorway.
NSW Minister for Transport and Roads Andrew Constance said the systems will ensure less stop-start traffic and sudden braking at some of the most congested points along the motorway.
"When the project is complete, these systems will talk to each other and automatically adjust to incidents and congestion without a manual operator intervening," Mr Constance said.
"This testing will measure driver behaviour and reaction to the technology ahead of the project opening to traffic."
"By introducing these cutting-edge improvements, we ensure drivers are spending less time in their vehicles and more time doing what they enjoy most."
Planning will also continue on technology upgrades to other major motorways, including the M1 Motorway between Gosford and Sydney.
