On Highway Tunnel Intelligent Control

2007 Chinese Control Conference, 2006
This paper analyzed the status quo of highway tunnel control system, and pointed out that the present control system overemphasizes the realization of individual system's function and neglected the consideration of the whole effect. This paper proposed a new research approach, which was to use information fusion technology to process the detected ...

Prevention and Control of Highway Tunnel Fires

1984
This study investigates steps that can be taken to reduce the risk, damage, and fatalities from fires in existing and future highway tunnels and the effect of unrestricted transit of hazardous materials through them. The history of highway tunnel fires is examined to discover the design and operating features bearing on ignition, spread, detection ...

On the determination of the aerodynamic coefficients of highway tunnels

Journal of Wind Engineering and Industrial Aerodynamics, 2002
Abstract The determination of the aerodynamic coefficients of highway tunnels is crucial to set up an accurate theoretical model of tunnel ventilation. Their appropriate values vary with situations, such as traffic conditions, auxiliary facilities in tunnel, jet fan performance, and so on, and accordingly shall be determined in real situations.

Evaluation of Fire Risk at Highway Tunnels

ICCTP 2009, 2009
The purpose of this study is to prevent and reduce fire at highway tunnels. This paper systematically analyzes the influence factors for the safety system of highway tunnels, establishes a risk assessment model for tunnel fire based on analytic hierarchy process and multi-grade fuzzy evaluation, and introduces a risk factors assessment system for ...

Maintenance and control of the Kanmon highway tunnel

Tunnelling and Underground Space Technology, 1986
Abstract Kanmon Highway Tunnel is a 3.5-km-long undersea road tunnel linking Honshu Mainland and Kyushu Island under the Kanmon Straits. Carrying a traffic volume of approx. 25 000 cars per day, the tunnel plays an important role as a main trunk road (National Highway Route 2).

Bridges and Tunnels on Highways in Croatia

2004
Development of highway network is taking place at the moment in Croatia. The plan is including construction of about 1200 km of new highways that should connect all larger Croatian cities (Dubrovnik, Split, Zadar, Pula, Rijeka, Osijek) with the capital of Republic of Croatia, Zagreb.

Highway tunnel safety detection and management

城市建设理论研究—建筑结构
Highway tunnel is an important part of highway engineering, and its safety detection and management play a pivotal role in the construction and maintenance process of the whole project. However, due to the particularity of the tunnel itself, the engineering quality is difficult to guarantee, and there are many safety risks.

EMERGENCY SIMULATION IN A LONG HIGHWAY TUNNEL

2020
In regions that are difficult to overcome geographically in road transport, tunnels both shorten the road to be covered and save fuel. It is the worst scenario that a vehicle can burn in a tunnel. There have been major tunnel fires in the world that have resulted in people's lives.

Surveillance and Control Systems for Highway Tunnels

1996
Unlike open highways, tunnels require special attention to maintain safety under normal and abnormal traffic conditions. Most modern tunnels, including their approach roads, require a centralized control system to meet these goals. Although not all tunnels require the same attention or installed features, they all have the following general features ...

Zion-Mount Carmel Highway and Tunnel

Civil Engineering Magazine, 2016
For years supporters of the Zion National Park, in southwestern Utah, dreamed of connecting the state’s two main north-south routes, highways 91 and 89, to improve access to the park. In 1930 that connection was made with the opening of the Zion-Mount Carmel Highway and Tunnel.
