SPEED cameras on the A127 have issued 755 tickets in nearly 18 months of operating.
Figures obtained under the Freedom of Information Act revealed 613 of the tickets have been paid raising £36,780 for the Treasury.
Essex County Council spent £1.2million on installing the cameras between Nevendon and the Southend boundary.
They police a 70mph limit between Nevendon and the Dick Turpin pub and a 50mph limit between the pub and Southend.
The council claims tickets are being issued for the full stretch of road and the cameras are catching an average of about 44 motorists a month.
An Essex County Council spokesman said: “Safety cameras are not installed to raise revenue, they are one of a number of enforcement tools that are used to reduce the number of killed or serious casualties on a particular route.
“Any revenue raised by safety cameras does not benefit the county council, as all funds go directly to the HM Treasury.”
The cameras were installed in January 2009. They did not start working until April 9 that year, but the council has never explained what the problem was.
Transport chiefs argued they were necessary to cut accidents on the 6.8-mile stretch which had seen four people die and more than 250 seriously injured between 2006 and 2009.
A report by the Essex Casualty Reduction Board shows within the 50mph zone collisions resulting in death or serious injury have fallen by 86 per cent, from 7.3 a year to one a year.
The cameras have had less impact in the national speed limit zone where serious collisions actually increased in the period immediately after the installation of the cameras from 3.3 a year to 5.5.
However, none of the crashes since the installation of the cameras has been fatal and the number of collisions resulting in more minor injuries has fallen by 54 per cent across the whole stretch.
The spokesman added: “The main priority for the use of speed enforcement cameras is as a collision reduction measure.
“The average speed camera scheme was introduced due to the high number of collisions and casualties that occurred on this route.
“Since the introduction of the scheme there has been a 54 per cent reduction in the rate per year of collisions, so we are pleased to see they are achieving their goal.”
