Urban road tunnels provide an increasingly cost-effective engineering solution, especially in compact cities like Singapore. For some urban road tunnels, tunnel characteristics such as tunnel configurations, geometries, provisions of tunnel electrical and mechanical systems, traffic volumes, etc. may vary from one section to another. These urban road tunnels that have characterized nonuniform parameters are referred to as nonhomogeneous urban road tunnels. In this study, a novel quantitative… 
QRA model-based risk impact analysis of traffic flow in urban road tunnels.
TLDR
An "excess risk index" is proposed in order to quantify the road tunnel risk magnitudes that do not pass the safety target and can be illustrated by a contour chart based on the excess risk.

TLDR
A Monte Carlo-based estimation method is developed to propagate parameter uncertainty in quantitative risk assessment model consisting of event tree analysis as well as consequence estimation models to assess tunnel risks by taking into consideration two types of uncertainties.
Challenges for current quantitative risk assessment (QRA) models to describe explicitly the road tunnel safety level
The number of road tunnels in Europe has increased rapidly over the last years. Nevertheless, this increasing number is raising upfront an endogenous problem, which is the severity of accidents that
Traffic safety analysis of inter-tunnel weaving section with conflict prediction models
TLDR
The length of the diverging section, merging section, and whole weaving section are found to be significant influencing factors on the conflict occurrence and are expected to help engineers better design inter-tunnel sections.

Optimal Allocation of Tunnel Safety Provisions Based on a Quantitative Risk Assessment Model
TLDR
An optimization model is proposed to obtain the optimal solution for the selection of tunnel safety provisions and a Bi-Section Search and Bound Algorithm BSSBA is designed to efficiently solve the problem.

The tunnel collapse, a large deformation of surrounding rock, water and mud inrush are the main geological disasters in the process of tunnel construction. In order to control the above construction
A Risk Evaluation Method with an Improved Scale for Tunnel Engineering
Analysis and evaluation of risks in tunnel construction is commonly performed using various scales; however, such scales have serious limitations. In this paper, an improved scale based on a fuzzy

TLDR
A calculation model has been developed that includes vehicle fires, spills of dangerous goods, traffic jams, the effects of incident detection, ventilation strategies and automatic or operator intervention as well as the escape possibilities of the road users.
