Operational Challenges of Managed Motorways

Managed motorways are being deployed as an alternative to road widening. They allow the capacity of the motorway to be dynamically controlled both automatically and by direct intervention from control room based operational staff in response to fluctuating traffic demand. To operate managed motorways safely and effectively, there is a greater reliance on technology than conventional roads, coupled with an increased requirement for operational contribution. Focusing investment on the enhanced use of technology delivers tangible benefits to the travelling public, and appropriate use and operation of technology can lead to compliant driver behaviour that brings significant benefits to the network. However, in order for these benefits to be realised, the technology required must be maintained to a sufficient standard to allow the network to be safely operated in accordance with the correct procedures. While the concept of ‘design for maintenance' is widely used and understood, the concept of ‘design for operation’ is a more novel concept that is explored further in this presentation.
