Highways England uses two algorithms to manage traffic on its network: queue protection (QP) to improve safety and congestion management (CM) to improve capacity. It is investing in large programmes to substantially improve network conditions on the strategic road network; this study aimed to consider whether the functionality of the SM algorithms can be delivered in a more efficient or effective way, to increase the benefits of these programmes. The key objective is to improve the experience of road users, by reducing congestion and providing more effective signals and information. Other potential benefits include cost savings, improved safety and reduced emissions. The study considered the use of alternative data sources, modifications to the existing algorithms and entirely new algorithms which could bring improvements to network safety and capacity and reduce operating costs. It found strong potential to improve performance and a strong case for further investment.
