Aberdeen Roads, a joint venture company of Balfour Beatty, Morrison Construction and Carillion, has secured a contract from Transport Scotland, for the installation of average speed cameras on the A90 highway at Charleston, which will be operational from 25 January.

The cameras have been deployed on this highway as part of the Aberdeen Western Peripheral Route / Balmedie to Tipperty project in order to enhance the safety for construction workers and road users.

The cameras have been installed to enhance the safety for construction workers and road users.

"In addition to the proven safety benefits of average speed cameras, their use in major road works schemes demonstrates their ability to improve traffic flow and journey time reliability."

Transport Scotland spokesperson said: “The average speed cameras on the A90 at Charleston are planned to be operational from Wednesday 25 January 2017.

"The signs which read ‘cameras under test’ will be removed in advance.

“These cameras are similar to the existing average speed cameras on the A90 between Blackdog and Balmedie, which have been operational since July 2016.

"The works at Charleston ‎took a step forward towards the end of last year following the introduction of the new traffic management measures.

“These were implemented while works are underway, including a 50mph speed restriction, which was introduced to improve the safety of road workers and road users.

“When the average speed cameras become operational, the speed restriction will remain unchanged at 50mph.

"However, the cameras will help to ensure that this speed restriction is observed.

"In addition to the proven safety benefits of average speed cameras, their use in major road works schemes demonstrates their ability to improve traffic flow and journey time reliability.”

For this project, Aberdeen Roads company is working closely with Transport Scotland, Aberdeen City Council, Aberdeenshire Council, Police Scotland and the North Safety Camera Unit over the use of average speed cameras in this area.

The transport agency has further explained that the average speed cameras will stay in place until the completion of works.
