“…In the experiment, drivers in the middle area of all the long tunnels had different degrees of driving fatigue, and driving fatigue is also an important feature that distinguishes long tunnels from short tunnels and general tunnels. Relevant research has indicated that, when the vehicle running speed is 60~100 km/h in the tunnel, drivers will experience different levels of driving fatigue at different sites in the middle area of the tunnel [43]. With involuntary acceleration, increased speed dispersion, and even sleep, the traffic safety risk will increase sharply.…”

The tunnel is an important component of freeway operation safety, and its classification method is the foundation of a refined management of operation safety. At present, the impact of different categories of tunnels on driver safety, comfort, and driving behavior under naturalistic driving conditions is not clear, and there is a lack of classification methods for tunnels of different lengths in their operation stages. This paper was based on the driving workload, which effectively expresses the safety and comfort of drivers. In this context, naturalistic driving experiments in 13 freeways and 98 tunnels with 36 participants were carried out. The DDTW+K-Means++ algorithm, which is suitable for drivers’ driving workload time series data, was used for a clustering analysis of the tunnels. According to the length of the tunnel, the operation-stage tunnels were divided into three categories: short tunnels (<450 m), general tunnels (450~4000 m), and long tunnels (>4000 m). The length of the tunnel had a positive correlation with the drivers’ driving workload, while there was a negative correlation with the vehicle running speed, and the range of changes in the drivers’ driving workload and operation safety risks in general tunnels and long tunnels was higher than that in short tunnels. Road and environmental conditions are important factors affecting the driving workload. The entrance area, the exit area of tunnels, and the middle area of long tunnels are high-risk sections in the affected area of the tunnel. These research results are of great significance for the operation safety management of freeway tunnels.

“…The third category is extensive research and improvement of tunnel luminaires. [14][15][16] On the basis of the visual characteristics of the driver [17][18][19] and the visual environment in the tunnel, a series of numerical calculation guidelines has been developed. 20 Avotins et al 16 found that the application of LED replacement high-pressure sodium(HPS) luminaires provided energy savings of up to 47% for street lighting.…”

To achieve energy saving and safe driving in a tunnel, this work proposes a tunnel intelligent dimming control and energy consumption monitoring system. Firstly, a dynamic predicted tunnel traffic volume is established to optimize the timeliness of the system tunnel traffic volume. Secondly, a backpropagation neural network-based dimming control model is constructed, in which the luminance outside the tunnel, traffic volume and vehicle speed serve as the input, and the luminance inside the tunnel is the output. This model is then combined with the established integrated closed-loop control model of the tunnel internal and external luminance to achieve continuous dimming control of the tunnel. Finally, an energy consumption monitoring system is designed with an energy monitoring unit. The designed system was implemented and tested for 63 days in the Yongtaiwen–Chayuanli (China) tunnel. Experiment results show that the designed system can automatically control the luminance of the tunnel lighting according to the luminance measured outside the tunnel, traffic volume and vehicle speed, thus achieving continuous dimming control. This significantly reduced the power consumption (by approximately 65%) whilst ensuring the safety of tunnel traffic.

“…The evaluation of perceived safety in streets and other civil infrastructures [18][19][20][21], and also in nuclear plants producing energy from fission [22][23][24][25][26][27], are fields of active research, widely approached in the literature, whilst the perceived psychosocial hazards in experimental facilities devoted to testing new ways of energy production are scarcely studied. The choice of a survey for their evaluation is a feasible and useful tool that allows people to express their opinion so that Public Administrations can plan special projects without negative impact on people living in the surroundings.…”

People’s Perception of Experimental Installations for Sustainable Energy: The Case of IFMIF-DONES

2022

View full text Add to dashboard Cite

Nuclear facilities are a main milestone in the long way to sustainable energy. Beyond the well-known fission centrals, the necessity of cleaner, more efficient and almost unlimited energy reducing waste to almost zero is a major challenge in the next decades. This is the case with nuclear fusion. Different experimental installations to definitively control this nuclear power are proliferating in different countries. However, citizens in the surroundings of cities and villages where these installations are going to be settled are frequently reluctant because of doubts about the expected benefits and the potential hazards. In this framework, knowing the opinion of people and their perception of experimental fusion facilities is essential for researchers, administrations and rulemaking bodies planning future fusion plants. This is the case for IFMIF-DONES, a neutron irradiation facility to determine the most suitable materials for the future fusion reactors. The construction of this installation is starting in Escúzar (Granada, Spain), and this work presents a large survey among 311 people living or working in the village. Their perception, fears, hopes and other variables are analyzed, and the conclusions for future installations and their impact on the energy policy are presented.
