Collision Warning with Auto Brake - A Real-Life Safety Perspective
Automotive safety has gained an increasing amount of interest from the general public, governments, and the car industry. This is more than justified by traffic accident statistics, as each year around 1.2 million people die due to road traffic accidents. For these reasons safety remains a core value of Volvo Cars. This paper presents some of the latest active safety developments within Volvo Cars. Rear-end collisions are common accident scenarios and a common cause of these accidents is driver distraction and thus not reacting in time. No vehicle system is a substitute for the most important safety feature in any vehicle: the driver. However, Volvo is harnessing innovative technologies to help alert drivers to avoid potential collisions and reduce the potential impact speed when a collision cannot be avoided. One of those systems is Collision Warning with Auto Brake where the area in front of the vehicle is continuously monitored with the help of a long-range radar and a forward-sensing wide-angle camera fitted in front of the interior rear-view mirror. A warning and brake support will be provided for collisions with other vehicles, both moving and stationary. Additionally, if the driver does not intervene in spite of the warning and the possible collision is judged to be unavoidable; intervention braking is automatically applied to slow down the car. This aims at reducing impact speeds and thus the risk for consequences. This system has been verified using innovative CAE methods and practical tests. Finally, it is discussed how the benefit of such systems can be judged from real-life safety perspective using traffic accident statistics.

VANET-DSRC Protocol for Reliable Broadcasting of Life Safety Messages
This paper proposes a novel protocol for reliable broadcasting of life safety messages in Vehicular Ad-hoc Networks (VANETs) simulating reactions of car drivers. In case of any dramatic change of speed or moving direction, the vehicle is considered abnormal and hence it transmits an emergency warning message over the control channel of the Dedicated Short-Range Communication Protocol (DSRC). The proposed protocol gives the vehicle in the most dangerous situation the highest priority to transmit the acknowledgement signal. The choice of that vehicle is done locally based on the location, direction, and speed of the receiving vehicle. The superiority of the proposed protocol over existing protocols is highlighted conceptually and with simulations.

The development of a Life Safety Model to estimate the risk posed to people by dam failures and floods
Dam owners face important decisions about the ways in which finite resources should be allocated to ensure the continuing safe operation of ageing dams. Dam safety risk assessments depend on credible estimates of loss of life for hypothetical failure events to aid in quantifying risk and making decisions concerning how structures are maintained. This paper briefly describes the development of a model, called the “Life Safety Model”, to provide a physics based, dynamic model to estimate loss of life and evacuation times that can result from extreme flood events. The Life Safety Model has an agent-based simulator that enables the model to represent a myriad of probable scenarios which could result from a flood event. Unknown variables such as the effectiveness of warning, road capacity, and time varying population density can be tested in a range of scenarios. The Life Safety Model uses results of flood water depth and velocity from two dimensional hydraulic models such as Telemac 2D over the course of the event, to represent the flood hazard. Unlike many other models and methods of this kind the Life Safety Model includes a dynamic interaction between the receptors and the flood hazard. The paper describes the application of the model to the Malapasset Dam disaster that occurred in 1959 in the south of France. The application of the Life Safety Model to this disaster demonstrated that the model was capable of making accurate estimates of loss of life from an actual flood event.

The Real-Life Safety and Efficacy of vardenafil (REALISE) study: results in men from Europe and overseas with erectile dysfunction and cardiovascular or metabolic conditions.
INTRODUCTION The Real-Life Safety and Efficacy of vardenafil study is an international, open-label, prospective, noncomparative, noninterventional study in men with erectile dysfunction (ED). AIM To determine the safety and efficacy of vardenafil in a large international pool of men with ED (aged ≥ 18 years) and associated underlying conditions (N=73,946), in a real-life setting. METHODS Patients attended an initial physician visit and one to two follow-up visits. Data were acquired by physician interviews and patient diaries and recorded in case report forms (CRFs). Data were pooled from 47 countries in Europe, Asia-Pacific, Latin America, and the rest of the world (excluding the United States and Japan for methodological reasons). Results were stratified by baseline ED severity, body mass index (BMI), and the presence of hypertension, diabetes, lipid metabolism disorder, or cardiovascular disease (CVD). MAIN OUTCOME MEASURES CRFs and patient questionnaires containing questions on overall improvement of erection, satisfaction with efficacy, and desire to continue vardenafil use. RESULTS Many participants had hypertension (32.0%), diabetes (22.1%), lipid metabolism disorder (14.6%), or CVD (42.2%). High percentages of patients reported improvements in erectile function, irrespective of baseline ED severity (mild, 97.0%; moderate, 96.2%; severe, 85.5%), BMI (<25, 94.1%; ≥ 25 and <30, 94.6%; ≥ 30, 92.9%), or the presence of hypertension (93.6%), diabetes (92.6%), lipid metabolism disorder (94.7%), or CVD (93.3%). Over 90% of patients, including those with underlying conditions, reported being "satisfied" or "very satisfied" with vardenafil efficacy, and stated their intention to continue vardenafil use after the end of the study period. The incidence of adverse events was low, and 97.0% of patients were either "satisfied" or "very satisfied" with vardenafil tolerability. CONCLUSIONS These data from a worldwide population of men with ED and associated underlying conditions show that vardenafil is effective and well-tolerated for the treatment of ED in a real-life setting, supporting its use as a first-line ED therapy.

Quantitative Assessment of Building Fire Risk to Life Safety
This article presents a quantitative risk assessment framework for evaluating fire risk to life safety. Fire risk is divided into two parts: probability and corresponding consequence of every fire scenario. The time‐dependent event tree technique is used to analyze probable fire scenarios based on the effect of fire protection systems on fire spread and smoke movement. To obtain the variation of occurrence probability with time, Markov chain is combined with a time‐dependent event tree for stochastic analysis on the occurrence probability of fire scenarios. To obtain consequences of every fire scenario, some uncertainties are considered in the risk analysis process. When calculating the onset time to untenable conditions, a range of fires are designed based on different fire growth rates, after which uncertainty of onset time to untenable conditions can be characterized by probability distribution. When calculating occupant evacuation time, occupant premovement time is considered as a probability distribution. Consequences of a fire scenario can be evaluated according to probability distribution of evacuation time and onset time of untenable conditions. Then, fire risk to life safety can be evaluated based on occurrence probability and consequences of every fire scenario. To express the risk assessment method in detail, a commercial building is presented as a case study. A discussion compares the assessment result of the case study with fire statistics.

Advanced smart airbags: The solution for real-life safety?
Abstract Today, numerical simulation is used all over the world to develop and optimise the restraint system performance. But more than just helping engineers to design restraint systems fulfilling the homologation and ratings requirements, the numerical simulation enables them to extend their field of investigation by going beyond the laboratory test conditions, making their first steps in “real life safety”. This paper presents the simulation of a concept of an adaptive restraint system for the passenger side. Its restraint capacity is continuously adjustable to the occupant, by an airbag whose shape and volume can be varied. In addition to this, the airbag outflow hole characteristics have also been optimised. The performance of this restraint system has been evaluated using the three standard adult dummies (5th, 50th and 95th percentile), each one in various seating positions for both US and Euro-NCAP pulses. The results will be shown with respect to a state-of-the-art restraint system. The design process, starting from the 95th percentile dummy, will be explained as well as the problems encountered during the optimisation process.

Multivariate Methods for Life Safety Analysis in Case of Fire
The assessment of life safety in case of a building fire is based on the comparison of the available safe egress time (ASET ) and the required safe egress time (RSET ). With regards to simulation experiments, this straightforward approach is accompanied by uncertainties including the underlying models, the specification of inputs, and the analysis of outputs. Concerning the two latter aspects, this thesis introduces methodological extensions in order to conduct ASET -RSET analyses in a multivariate fashion. For the specification of inputs, the multitude of possible scenarios is represented with the help of systematic sampling techniques. Uncertainties in terms of analysis are tackled with multi-criterial maps rendering both ASET and RSET in spacious environments. The subtraction of both maps is used to determine a measure of consequences. These methods are applied to a multi-level underground station which is investigated with numerical simulations based on the formation of two subsystems, namely Fire and Evacuation. The analysis incorporates an ensemble of 8, 640 combined fire scenarios and evacuation scenarios. Throughout the entire design space, more than 95 % of the scenario combinations account for less than half of the maximal observed consequences. This analysis is refined by agglomerative clustering in order to group all observations hierarchically. It becomes evident that the lowest margins of consequences are represented by two clusters covering approximately 75 % of all observations. The investigation of the parametric relations of all clusters allows for the systematic identification of the determining characteristics of fire and evacuation scenarios. In addition to the consequence measure derived from ASET -RSET, fractional effective doses (FED) are calculated to supplement the analysis. Within the clusters, the number of occupants exceeding common FED thresholds applicable to incapacitation corresponds to the introduced ASET -RSET measure. However, throughout the entire design space, this correspondence is not clear and needs further investigation.

On the Regulation of Life Safety Risk
The present paper takes up the issue of appropriate choice of metric for life safety and health related risks in a regulatory context addressing effects of temporal and spatial scales for their consistent quantification and comparison across societal sectors, industries and application areas. Starting point is taken in a short outline of what is considered to comprise the present best practice rationale for life safety and health risk regulation. Thereafter, based on selected principal examples from different application areas, inconsistencies in present best practice risk quantification in a regulatory context are highlighted and discussed. It is identified and explained that the principle of decision optimization and conjoint fulfillment of the marginal lifesaving principle does not render the assessment of the individual life safety risks for specific individuals relevant. Nor is the resulting absolute level of individual life safety risk subject to assessment of acceptability. It is highlighted that a major cause of inconsistency in risk quantifications and comparisons originates from the fact that present regulations partly address societal activities and partly address applied technologies; in some cases take the perspective of individuals and in other cases address the performance of applied technologies. It is furthermore shown that the typically applied averaging of individual risks over time and space may result in unintentional masking of poorly performing activities and applied technologies. Finally, a proposition is made on how the individual life safety risk may be assessed and compared consistently and uniformly over different activities and applied technologies.

WALKING SPEED IN SMOKE: REPRESENTATION IN LIFE SAFETY VERIFICATIONS
The gradual transition from prescriptive to performance-based regulations has led to a worldwide development of methods and techniques for designing and verifying the fire and life safety performance of buildings and infrastructure. During, for example, the design of complex underground structures, such as road and rail tunnels, a structured risk assessment method is often adopted within which a number of representative fire and evacuation scenarios are identified, analysed and assessed using advanced calculations. Typically, these include an analysis of peoples’ ability to safely evacuate the infrastructure without being exposed to untenable conditions according to the so-called egress time-line model [1]. In practical terms, this means that the required safe escape time (RSET) is compared to the available safe escape time (ASET) for each scenario in more or less independent fire and evacuation calculations or simulations. In addition, a more advanced technique may also be adopted, in which the accumulated dose of irritating and/or toxic gases are compared to the doses resulting in incapacitation or death according to the so-called fractional effective dose (FED) concept [2].
