Transport Minister Keith Brown says salt stocks have been maintained and supplies of specialist de-icers that work in even lower temperatures have been increased.
There are also additional frontline and patrol vehicles available.
A dedicated adviser from the Met Office has also been installed at the National Traffic Scotland control centre in South Queensferry, West Lothian, which opened this year.
The public will be kept up to date with information on road conditions via the Traffic Scotland website and social media sites.
Weather stations are now located across the country and mobile sensors are fitted to operational vehicles to feed back data on road temperatures and conditions. This will be used by the road-operating companies to decide when routes need to be treated.
Speaking during a tour of the control centre, Mr Brown said: "Last winter, the Met Office issued 169 severe weather warnings for Scotland and that gives an indication of some of the challenges we could face during the next few months.
"Our new national control centre means our response to major incidents, such as severe storms, will be better co-ordinated under one roof with experts from all across the transport network working alongside each other.
"We have made all the preparations necessary to ensure our decision making, winter treatments and communications improve again this year."
