“…Currently, many studies was done about the safety of freeway [4][5][6][7][8][9][10] , however, there is less reach about safety of traffic operation environment for freeway tunnel. The related research mainly focuses on tunnels ventilation systems, lighting systems and fire protection technology [11][12][13] . Numerical simulation techniques and logical mathematical model was used to develop a security risk assessment system and a range of preventive strategies.…”

This study developed a safety evaluation model for traffic operation environment of freeway tunnel based on the grey entropy weight clustering. Firstly, a safety evaluation system was proposed including four aspects related road conditions, traffic operating conditions, environmental conditions and climate condition. Secondly, whitenization weight function was defined and weights of indexes were determined by entropy theory. Thirdly, the grey entropy clustering coefficient was calculated, and the safety level for traffic operation environment of freeway tunnels was evaluated. Finally, a case study of seven tunnels of XI-HAN freeway was conducted to verify the feasibility and effectiveness of the model.

“…On the other hand, smoke control of fires in subway stations and stack effects on smoke propagation are simulated and compared with experiments with great accuracy [20,21]. Ventilation strategies and application to fire in a long tunnel has been considered [22] and ordinary and emergency ventilations are operated by using dedicated supply and extraction ducts. Another key parameter for tunnel fires is the critical speed and simulation results show a good correlation with real fires [23].…”

Due to land scarcity in greater Taipei area, continuously conversion from existing railroad to underground are performed to increase the land utility at different phases and span many years. In addition, integration issues between several transportation systems such as mass transit and high speed rail are also of great concerns. Fourth phase of Nangkang North Tunnel was completed and in full operation in September, 2008. During the construction period, fire codes in Taiwan for special constructions (e.g. ubnderground stations) are also going through various revisions while internationally, new regulations such as AS 4391 in Australia and NFPA130 in USA have been validated and updated. In order to verify the compliance of fire codes nationally and internationally, full scale experiments have been performed before opening to public service with emphasis on various operation modes of mechanical ventilation. This paper aims to numerically investigate and compare the effectiveness of CFD (Computational Fluid Dynamics) with experimental results. As a matter of fact, full scale experiments are implemented in fire codes in Taiwan for the structures which cannot fully comply with normal installation of fire equipments. While computational power and resources are improving tremendously in the past few years, we focus on the potentials to gain insightful information through numerical simulation and provide a repeatable reference for the engineers, designers and fire fighters as well as managerial levels in government before undertaking any full-scale experiment.
