The Impact

The road network is a land transportation infrastructure that plays an important role in the transportation sector, especially for the balance of the distribution of goods and services, both from other regions. In this study, an analysis was conducted to find out how the influence of heavy vehicle volume increase on the service life of the road, while the method used was Bina Marga, the study was conducted by taking a case study on the Hera road section until Dili. This research is expected to find out how the service life of the road if the volume of heavy vehicles continues to increase. If the% of heavy vehicles increases, the thickness of the required surface layer will also be even greater. When% of vehicles or carrying heavy traffic loads are increased, the thickness of the existing layer cannot meet, because the calculation results with% of heavy vehicles increase by 10%, surface thickness 17.2 cm / This will cause the service life of the road to decrease because it is confirmed that the road will be damaged before the service period ends due to excessive load increase in heavy vehicles.

The Impact

The subject of this paper is the impact of road lighting on the capacity of uninterrupted motorway sections. A capacity estimation method was used that is based on extrapolation of the free-flow part of the fundamental diagram representing the relation between flow rate and density. The method assumes that the density at capacity is not affected by illumination, which implies that capacity shifts are fully the result of speed changes. The method was applied in a Dutch case study. In a before-and-after study, the impact of road lighting was estimated for two directions of one road section. Capacities of the road section were estimated for various periods of the day. Capacities during the daytime did not differ significantly before and after introduction of lighting. Nevertheless, during nighttime a significant increase in capacity of about 2.5 percent was found.

The Impact

The Coronavirus disease 2019 (COVID-19) affect­ed almost all activities worldwide. The medical sec­tor was one of those which were most significantly impacted because the medical infrastructure was not sized for such a high scale shock, specialized human resources and medical infrastructure prov­ing to be much undersized and with slow growth potential. Many changes were required, important financial resources being mobilized in order to mo­tivate medical staff, offer treatments for the most severely affected patients, but also to create new fa­cilities where the increasing number of sick persons could be cured. In our research we want to offer a hospital cost perspective based on empirical analysis of the COVID-19 impact on different categories of expens­es made by Romanian hospitals that treated patients with COVID-19 in different stages of their disease. The period analyzed was January 2019 to December 2020 on a monthly basis. Our results showed that expenses with goods and services, drugs, reagents and human resources are influenced by COVID-19 in a significant manner.

The road sector is one of the main sources of air emissions in the atmosphere during both construction and operation. The objective of the present paper is a comprehensive evaluation of the impact on air quality during the two main phases of life cycle of roads. In this case study of a motorway project, the emissions of the primary pollutants, CO, NOx, and PM10 are estimated, and the results showed that (i) CO and NOx pollutants released during both phases are comparable, while the emissions of PM10 are more significant in the construction phase; (ii) 85% of PM10 in construction is due to storage, transit on unpaved road, and crushing; (iii) the portals of the tunnel are the sites where there are higher concentrations of pollutants in operation; and (iv) the CO concentrations estimated by the dispersion model are strongly influenced by the topography.

The Impact

The object of the study is the improvement of traffic management on the main street and road network of the city. Actually, there are many techniques that allow simulating the traffic flows with sufficient accuracy. One of such models is a mathematical model, which allows calculating the main characteristics of a traffic flow on the basis of a few initial data and is considered as a queuing system.Modeling allows pre-determining the impact of traffic management measures on the existing street and road network without creating interference for drivers, making changes to the design of road, increasing the traffic volume, as well as involving the possible overloaded areas.An analysis of the researches of scientists who have considered similar methods in their works had been performed. The fundamental flaw of the mentioned works is that in none of them the study of the model of a real road section was performed for verifying of the model adequacy. Modeling allows understanding more accurately the behavior of an object with less approximations than mathematical models, and provides less researching and forecasting of the system behavior with significant changes in the initial concepts. It is indicated that for the first approximation it is expedient to use mathematical models, and for clarifying the characteristics – to use non- mathematical methods, in particular, simulation.It is proved that simulation is a powerful tool for studying the behavior of real systems. It is mainly used to study situations and systems that can be described as queuing systems.Using the queuing theory, it becomes possible to perform certain calculations and determine indicators of effectiveness of the queuing system.Obtained result of the indicators will help to determine the street and road network areas where a traffic jam may form for any reason, where the road will be overloaded. This makes it possible to develop a high-quality algorithm for quick elimination of traffic jam.

The Impact

The traditional definition of sustainability calls for policies and strategies that meet societys present needs without compromising the ability of future generations to meet their own needs (1). Sustainability is a concern in private and public sectors all over the world; it is an issue that resonates with people in all age ranges, income levels, and geographic locations. The main idea of sustainability is reduce, reuse, and recycle. People and organizations alike must consider every possible effect from the decisions they make in regards to the environment. With over 600,000,000 passenger cars on the road in the world, and over 50,000,000 passenger cars built each year, it is imperative that automakers make sustainable decisions (2). It is not just the large number of vehicles in the world that is cause for concern, but the immense amount of resources needed to manufacture, transport, and fuel them. Automakers must consider the impact that each car has during every stage of its life cycle, in addition to their responsibility to society (in terms of the environment, education, and safety) and the impact of their suppliers. This case study is designed to discuss the background of Toyota and highlight the companys current actions in regard to sustainable marketing; a comparison will also be made to the sustainable efforts of Honda and Subaru.

The Impact

Traffic incidents (heavy traffic, adverse weather conditions, and traffic accidents) cause an increase in the frequency and intensity of the acceleration and deceleration. The result is a very significant increase in fuel consumption. In this paper, we propose a solution to reduce the impact of such events on energy consumption. The solution detects the traffic incidents based on measured telemetry data from vehicles and the different driver profiles. The proposal takes into account the rolling resistance coefficient, the road slope angle, and the vehicles speeds, from vehicles which are on the scene of the traffic incident, in order to estimate the optimal deceleration profile. Adapted advice and feedback are provided to the drivers in order to appropriately and timely release the accelerator pedal. The expert system is implemented on Android mobile devices and has been validated using a dataset of 150 tests using 15 different drivers. The main contribution of this paper is the proposal of a system to detect traffic incidents and provide an optimal deceleration pattern for the driver to follow without requiring sensors on the road. The results show an improvement on the fuel consumption of up to 13.47%.

Landslides and roadside slope failures resulting in road blockage, damage and economic losses are regular phenomena in the mountain regions of Nepal. Road construction in the northern belt of Himalaya is a challenging task, mainly due to the anticipated geo hazard in the region and remoteness of the area. The situation is often intensified in the region due to limited engineering geological and geotechnical information. The geo disaster risk further increases due to road construction. Geo hazard assessment is prerequisite to have best road alignment in mountain areas that are basically landslide-prone in many cases. The products of space science (like satellite imageries) could be a better choice for this purpose because of availability of high resolution imageries and their ready availability. The data acquired from space borne technology can be used to better assess the geological hazard condition along the road alignment. The present paper focuses to this aspect with the case study of a road section of Taplejung-Olangchunggola- Nangma, reaching the Nepal-Tibet border. The geo hazard assessment along the road corridor has been carried out through extracting the relevant information from satellite images in addition to the use of available secondary information as well as field study. A GIS database has been developed with the required information, which was used to prepare various thematic layers (like geology, drainage density, slope, aspect, rainfall), followed by further analysis. The suitability of the existing alignment has been evaluated with respect to the geo hazard condition along the road alignment.
