The majority of society, including politicians, scientists and visionaries, see only the advantages of implementing autonomous vehicles into road traffic, forgetting about the possible dangers and risks associated with the functioning of such transport. The article presents most of the present and future possible problems and risks of cooperation between autonomous vehicles and the functioning of transport. The conduced legal and economic analysis indicates a number of problems with the implementation of autonomous vehicles, which may cause, apart from obvious positive solutions, also a high risk in terms of road safety and the need to adapt the current legal acts. We should strive for maximum material recovery from end-of-life vehicles, including electronics and electrical installations of modern EV/HEV, particularly “rich” in scarce and critical metals. Electric and electronic scrap is most often classified as hazardous waste in the group of industrial waste. This is mainly due to the content of compounds that are particularly harmful to human health and the environment and at the same time highly desirable.

The Stability

In order to explore the changes that autonomous vehicles would bring to the current traffic system, we analyze the car-following behavior of different traffic scenarios based on an anti-collision theory and establish a traffic flow model with an arbitrary proportion (p) of autonomous vehicles. Using calculus and difference methods, a speed transformation model is established which could make the autonomous/human-driven vehicles maintain synchronized speed changes. Based on multi-hydrodynamic theory, a mixed traffic flow model capable of numerical calculation is established to predict the changes in traffic flow under different proportions of autonomous vehicles, then obtain the redistribution characteristics of traffic flow. Results show that the reaction time of autonomous vehicles has a decisive influence on traffic capacity; the q-k curve for mixed human/autonomous traffic remains in the region between the q-k curves for 100% human and 100% autonomous traffic; the participation of autonomous vehicles won’t bring essential changes to road traffic parameters; the speed-following transformation model minimizes the safety distance and provides a reference for the bottom program design of autonomous vehicles. In general, the research could not only optimize the stability of transportation system operation but also save road resources.

Shed Light

Abstract Drink-driving is a major cause of global road traffic fatalities, yet few countries have laws that meet international best practices. One possible reason is the alcohol industry’s opposition to meaningful policies that are perceived to directly threaten sales. Our primary objectives are to document alcohol industry involvement in global road safety policies and programmes and to critically evaluate the responses of public health and road safety communities to this involvement. Under the guidance of the Policy Dystopia Model, we used a mixed methods approach in which data were gathered from expert interviews and a mapping review of 11 databases, 5 watchdog websites and 7 alcohol industry-sponsored initiatives. Triangulation was used to identify points of convergence among data sources. A total of 20 expert interviews and 94 documents were analysed. Our study showed that the alcohol industry acknowledges that drink-driving is an issue but argues for solutions that would limit impact on sales, akin to the message ‘drink—but do not drive’. Industry actors have been involved in road safety through: (1) coalition coupling and decoupling, (2) information production and management, (3) direct involvement in policymaking and (4) implementation of interventions. Our study also shed light on the lack of cohesion within and among the public health and road safety communities, particularly with regard to the topics of receiving funding from and partnering with the alcohol industry. These results were subsequently used to adapt the Policy Dystopia Model as a conceptual framework that illustrates the ways in which the alcohol industry has been involved in global road safety. Several implications can be drawn from this study, including the urgent need to increase awareness about the involvement of the alcohol industry in road safety and to build a cohesive transnational alcohol control advocacy alliance to curb injuries and deaths related to drink-driving.

Transport Services

Countries of the developing world are characterized by rapid urbanization, high growth rates in traffic and congestion and decreasing regulation of public transport. Because the majority of the developing world's inhabitants are dependent on public transport services for their mobility needs, the need for safe, effective and efficient public transport is essential to ensure adequate, affordable, accessibility and the continuing sustainable development of livelihoods in the rural and urban. Finally, recommendations are made to reduce both the severity and number of public transport accidents in the future. This paper highlights the historical road safety and the transportation management in Dar es Salaam. In the field of road traffic control and management, the primary policy objective is to develop appropriate institutional and organizational arrangement towards further efficient road use.

Abstract Autonomous driving is a promising technology to, among many aspects, improve road safety. There are however several scenarios that are challenging for autonomous vehicles. One of these are unsignalized junctions. There exist scenarios in which there is no clear regulation as to is allowed to drive first. Instead, communication and cooperation are necessary to solve such scenarios. This is especially challenging when interacting with human drivers. In this work we focus on unsignalized T-intersections. For that scenario we propose a discrete event system (DES) that is able to solve the cooperation with human drivers at a T-intersection with limited visibility and no direct communication. The algorithm is validated in a simulation environment, and the parameters for the algorithm are based on an analysis of typical human behavior at intersections using real-world data.

Child Restraint

In the three years since the last road safety report was issued, the number of road traffic deaths has continued to increase throughout the Americas, reaching 154,997 deaths in 2016 (latest year of available data). However, the death rate from road traffic crashes has remained stable (15.6 per 100,000 population in 2016 as compared to 15.9 per 100,000 population in 2013). Data presented in this report show that aspects of road safety management, legislation, and post-crash care have improved in some countries. However, the improvements have been modest and it is clear that the Sustainable Development Goal (SDG) target 3.6, to halve road traffic deaths by 2020, will not be achieved... Since 2014, more countries in the Region have implemented road safety legislation. Two additional countries, the Dominican Republic and Uruguay, established laws on drink-driving based on best practice, bringing the total to eight countries. Ecuador implemented legislation on helmet use (resulting in a total of seven countries), Dominican Republic implemented legislation on seat-belts (19 countries in total), while Chile implemented child restraint laws (two countries in total). However, no new speed laws have been enacted in the Region. Overall, four countries (Chile, Dominican Republic, Ecuador, and Uruguay) have amended their laws regarding one or more road safety risk factors to bring them in line with best practice. Despite these legislative developments, enforcement remains a major challenge in most countries...

Lemon growing areas in the north of Argentina have industries that produce concentrated juice, peel and essential oil and generate a significant amount of liquid and solid waste as lemon pulp. In Argentina, despite the potential applications that the pulp has as animal feed and human and industrial raw material, only 10% is used for these purposes and the rest is discarded into the environment causing many ecological and economic problems. There is little information in the literature on biotechnologies for the treatment of this industrial waste. This paper shows that lemon pulp is a suitable substrate to be treated by anaerobic digestion. We obtained 86 and 92% reduction of chemical oxygen demand in a digester with a semi-continuous feed and retention time of 10 and 20 days respectively and a productivity of 0.406 g CH4/g VS h. Comparative tests showed that pre-digesting the pulp improved the process of digestion and increased biogas generation by 20%.

The appearance of slush on the road is determined by the intensity of precipitation, ambient temperature, surface and dew point temperature, atmospheric pressure and road traffic. The condition of slush (mixture of snow, ice, sand and chemicals such as salt) significantly affects the scope of road safety and the acceleration achieved in the driving processes. The agglomeration of slush in the space between the wheel and the wheel arches increases the resistance of the vehicle movement and increases the load on the suspension system and the steering. Excess snow and ice increases the risk of damage to these systems and may affect the steering and stability of the vehicle. The process of "deposition" of slush is particularly noticeable in environmental conditions with high humidity, and ambient and surface temperatures are below zero degrees Celsius. The article presents the idea of a system for removing slush from wheelhouse liners.
