Contrast Reduction

As per the Ministry of Road Transport and Highways report 2018, every day around 410 road fatalities in India, which is one of the highest road crash fatalities in the world. Evaluations show that an average of 1% of nighttime fatal crash lists glare as a major contributor factor. On the multilane highway, vehicle with high glared headlamp light disturbs the approaching motorist eyes due to which the vision of the motorist gets indistinct for a few seconds causing accidents on the road. In the present work, a novel concept of an anti-glare headlamp is proposed to avoid the temporary blindness of the motorist due to momentary high glares from approaching vehicles. The antiglare film reduces glare and halos around headlamp light at night and eliminates unattractive reflections on the eyes. A successful attempt is made to analyze the visibility of objects in a scene by inspecting contrast reduction caused by the illuminance contribution. Our visualization of scenes with the cover-up veiling illuminance gives a good indication of the visual problems that might occur, but the images are not exactly what people perceive when observing the scene in reality. In the present study, after number of samples, it has found that that the mixture of yellow and green color film combination on halogen bulb headlamp will give a good vision to the rider as well as glare-free effect to the approaching motorist. Visualizations with the proposed method can still improve the understanding of human vision so that visual aspects can be taken into account in design and quality assurance of head lamp.

Many precious lives are lost due to road accidents because of over speeding and negligent driving every day. This is the matter of great concern for departments that deal with road safety and for the citizens. It is estimated that 80% of crashes and 65% of near collisions are due to driver’s lack of attention to traffic for three seconds before the event. The number of road crash deaths has increased by 31% from 2007 to 2017. As per the survey on the road accidents in India, according to the Ministry of Road Transport and Highways, 1, 50,785 people were killed and another 4, 94,624 were injured in 4, 80,652 road crashes in India in 2016. Now day’s accidents are taking place at large scale. Majority of the accidents occurs due to the over speeding of vehicles, though there are speed limiting boards placed at the roadside of highways also at the road side in the city. But none of vehicles (drivers) follows the speed mentioned in the speed limit boards, due to which accidents occurs.

The dimensions and weight of machines, structures, and components that need to be transported safely by road are growing constantly. One of the safest and most widely used transport systems on the road today due to their versatility and configuration are modular trailers. These trailers have hydraulic pendulum axles that are that are attached in pairs to the rigid platform above. In turn, these modular trailers are subject to limitations on the load that each axle carries, the tipping angle, and the oil pressure of the suspension system in order to guarantee safe transport by road. Optimizing the configuration of these modular trailers accurately and safely is a complex task. Factors to be considered include the load’s characteristics, the trailer’s mechanical properties, and road route conditions including the road’s slope and camber, precipitation and direction, and force of the wind. This paper presents a theoretical model that can be used for the optimal configuration of hydraulic cylinder suspension of special transport by road using modular trailers. It considers the previously mentioned factors and guarantees the safe stability of road transport. The proposed model was validated experimentally by placing a nacelle wind turbine at different points within a modular trailer. The weight of the wind turbine was 42,500 kg and its dimensions were 5133 × 2650 × 2975 mm. Once the proposed model was validated, an optimization algorithm was employed to find the optimal center of gravity for load, number of trailers, number of axles, oil pressures, and hydraulic configuration. The optimization algorithm was based on the iterative and automatic testing of the proposed model for different positions on the trailer and different hydraulic configurations. The optimization algorithm was tested with a cylindrical tank that weighed 108,500 kg and had dimensions of 19,500 × 3200 × 2500 mm. The results showed that the proposed model and optimization algorithm could safely optimize the configuration of the hydraulic suspension of modular trailers in special road transport, increase the accuracy and reliability of the calculation of the load configuration, save time, simplify the calculation process, and be easily implemented.

Computerized traffic modeling makes it possible to find out the modification needs to assess the traffic flow on the roads and detect likely problem areas in order to take timely measures to eliminate them. Competent preparation of a road network formation plan based on the acquired information makes it possible to reduce the load on the road transport line, avoid traffic jams, and also reduce the average time spent by drivers on the roads. The macroscopic and microscopic models of the cars flow were analyzed by authors to implement the computer model. The article considered the model of the cellular automata by Nagel–Schreckenberg, with the author’s addition that takes into account the presence of the road sections inaccessible for driving in. The need to modify the lane change algorithm was implemented: the condition of the need to change the lane when car is meeting an inaccessible road section was added. And also the “polite” drivers algorithm for bypassing inaccessible areas with a high density of the traffic flows was proposed. Such a model is realized on Python programming language. An analysis of vehicles behavior with different traffic density and location of inaccessible road sections for two- and three-lane roads was carried out based on that model modification.

Abstract To ensure that road transport safety measures are effective and efficient, forecast tools should be applied to help with strategic decision-making. Models of road safety measures provide such tools. The paper presents a proposed macro model of road accident casualties. The proposed models of road accident fatalities are built from a database covering more than fifty countries worldwide. The concepts of model design can be used for developing factor-based models to describe strategic societal risk on the road networks of selected countries worldwide. One of the concepts was applied to model the number of road accident fatalities. The analyses used Smeed’s model and its modifications developed for the needs of this analysis.

Purpose of this study is to develop a logistics processes interaction model within the development of urban agglomeration, taking into account basic functional areas of logistics. Objectives of the study were to define the concept of "agglomeration logistics", to identify the main logistics processes of agglomeration, to calculate the logistics stability index (LSI) for the Almaty urban agglomeration In this paper such research methods as text analysis, logic modeling, survey method of analysis of hierarchies were used. The significance of the study lies in the development of a model explaining the nature of logistics processes interactions in Almaty urban agglomeration. The novelty of the research lies in adaptation and practical application of the methodology for assessing sustainability of urban agglomeration logistics and identifying most influencing factors in order to improve it. The main results of the research are: formulating the concept of "agglomeration logistics", identifying interaction algorithms of the main agglomeration logistics processes and calculating the logistics stability index for Almaty agglomeration. The following conclusions were made: there are problems of inefficient functioning of logistics processes within the agglomeration. Increasing number of road cargo and passengers has revealed the need to increase road transport network efficiency and carrying capacity; as a result of territorial structure, insufficient development of transport communications between the agglomerations ‘districts, loads on the road transport network increased, which led to violations of fundamental logistics` rules such as "just in time", "optimal route", "high delivery speed", which increases the load on logistics processes and hinders its integration; main constraints to the sustainability of logistics in Almaty agglomeration are air pollution and poor road safety.
