The government intends to create a framework worth up to £3 billion for traffic and parking management systems, as congestion increases on the UK's roads.
According to a contract notice issued today by Buying Solutions, the government's procurement arm, Whitehall plans to sign a four year agreement with "several" suppliers.
In a further indication that the government plans to buy more across multiple departments, the framework will be available to the Highways Agency, local councils, and all sizes of other organisations with an interest in managing road traffic or parking - including NHS trusts, the BBC and Royal Mail.
The agreement will encompass technology and services, and is split into lots.
Work available includes providing traffic and environment monitoring, traffic signals and electronic signs. The government is also seeking project management, traffic detection systems, speed activated signs, automatic number plate recognition, motorway incident detection and real time traffic data feeds.
Database integration and traffic monitoring services will be available on the framework, as will car park RFID and access systems.
Suppliers interested in participating have until 21 February to provide information.
