Impact of New Propulsion Technologies on Road Tunnel Operations and Safety - Literature review

Alternative propulsion technologies, including battery-electric vehicles, are becoming more prevalent. Whilst such vehicles remain a small overall proportion of the vehicle fleet, the combination of impacts of Government policy and technological advances in alternative fuels is expected to accelerate their increase in numbers on the road and in tunnels in coming years. There may also be particular initiatives in certain geographical areas, such as on airport land for example, where higher proportions [...]

Improving Road Tunnel Resilience, Considering Safety and Availability - Literature Review

This report presents a review of literature on the improvement of road tunnel resilience as well as a collection of case studies that illustrate how this topic is being dealt with in practice. The content of the report is addressed at several target groups involved in the planning, design, implementation, operation, maintenance and refurbishment of road tunnels, such as decision makers, tunnel owners and managers, tunnel operators, emergency response services, designers, tunnel safety experts, safety [...]

Improving Road Tunnel Resilience, Considering Safety and Availability - Literature Review

This report contains a review of literature on road tunnel resilience, including more general literature on resilience principles or aspects that could be applied to tunnels. Many definitions for “resilience” were found, but the Working Group decided on the following definition in the context of tunnels: “The ability to prepare and plan for, absorb, recover from, or more successfully adapt to actual or potential negative effects of events or developments affecting the availability of a road [...]

Large Underground Interconnected Infrastructure - Technical Report

This report is a continuation of the previous one published in 2016: “Road tunnels: complex underground road networks” (2016R19EN). Its objective is twofold: extend the panel of networks investigated, both geographically and in terms of their complexity and diversity, analyse in a much more thorough manner the particularities of this network nature, including: the geometry and impact of all the constraints related to the interchange points and connections, ventilation facilities: [...]

General Principles to Improve Accessibility for Persons with Reduced Mobility in Road Tunnels - Technical Report

The report provides the general principles that apply when making allowances for persons with reduced mobility in road tunnels. The means of facilitating their ability to raise the alarm, and to evacuate in critical situations, are examined. Facilities and examples from the following countries are provided: France, Slovak Republic, Denmark, Australia, the Netherlands, Germany, Austria, United Kingdom, Italy, Czech Republic, Sweden and Spain. The report is aimed at tunnel owners, designers and safety [...]
