The operation of smart motorways is a subset of broader transport operations and relies on complex organisational arrangements with highly specialised capabilities to manage a growing number of assets, follow a wide range of operational scenarios,…

Movement and Place is a multi-disciplinary, place-based approach to the planning, design, delivery and operation of transport networks. It broadens our thinking about our roads and streets beyond their functional role in supporting movement - they…

Road tunnels are an important element of the transport infrastructure, requiring significant resources and energy to construct, operate and maintain. Consequently, they are potentially a major source of greenhouse gas emissions and environmental…

This report documents a project undertaken to investigate the issues associated with managing the planning, construction, operation and maintenance of road tunnels in a sustainable manner. The results of the investigation informed an update to all…

Road tunnels are major pieces of infrastructure across the road network, and the number of tunnels is expected to increase in the coming years. Although they are relatively safe, a significant number of crashes occur on the approaches to and within…

This report evaluates selected low-cost perceptual countermeasure (PCM) treatments in tunnel environments. PCM treatments are used to reduce crash risk by improving driver speed behaviour, alertness and lane discipline within tunnels. Two key…
