Residents demanded action to prevent further fatalities on the A92 in Fife during a heated meeting.
During a public meeting in Glenrothes on Tuesday, Transport Scotland had hoped to outline a raft of minor road improvements.
As part of the plans, the speed limit from the Preston roundabout to north of the Balfarg junction will be reduced to 40mph.
But community members hit out at the £200,000 worth of measures, which they said are not enough.
In particular, they are calling for a roundabout at the Balfarg junction and for the route to be dualled.
Dr Robert Grant, whose daughter Lorna was killed in an accident on the road in 2010, said Transport Scotland’s response to the A92 action plan drawn up by Fife Council made him “very angry indeed”.
He said: “This community will not stay calm. We’re angry.
“I do not drive to Dundee unless I really have to because it’s such a dangerous road.”
Many attending the meeting objected to the way Transport Scotland had used accident data.
They believe Transport Scotland underestimated the hazards on the road by not including accidents where nobody was injured.
Dr Grant added: “This is not based on good evidence. You are the budget holder and you have made the solution to fit the budget.
“If you as a family have suffered a fatality as we have, the way you assess a road changes overnight.”
Commuter Joan Muszynski, who drives the stretch between Freuchie and Dundee, said: “I take my life in my hands every day going to work and think a lot of commuters say the same.”
Ms Muszynski said the mix of cars, agricultural vehicles and heavy lorries using the single carriageway stretches caused driver frustration and led to unsafe overtaking manoeuvres.
Fife Council leader David Ross said he planned to set up a meeting with the Scottish transport minister to press for A92 improvements including a roundabout at Balfarg.
And he said the local authority would like to see the route dualled between the Preston and New Inn roundabouts.
Transport Scotland’s head of road policy George Henry said “low cost measures” had been drawn up to improve road safety in the short term.
He said major, longer term investment in the A92 would be considered in a forthcoming review of strategic transport projects.
He said: “Our priority is to introduce some measures as quickly as possible to make a positive difference and these proposals represent a further £200,000 investment in this route by the Scottish Government.
“We remain committed to working with the communities of Fife as we go forward with these plans and on the wider issues associated with the local development plan and the trunk road network.”
