The Impact

This research proposes an innovative approach to evaluate modal shift from the road-only to the combined sea-road transport in order to implement new policies and introduce a Decision Support System (DSS) for the transportation planner’s decision. The impact of these is carried out by using an innovative simulation tool which has the capability to simulate the real choice process of all stakeholders involved, specifically modelling the freight forwarder’s point of view. The model runs as a single-agent based simulation which uses a multimodal network with detailed zoning. The simulation tool, capable of simulating the assignment of the whole network simultaneously, consists of a path choice model and a mode choice model for each o/d pair considered, establishing o/d pairs suitable and not suitable for modal shift. Three policies have been designed and tested through the simulation tool with an application in the Italian context: (1) internalization of the external costs of heavy vehicles; (2) introduction of a bonus for shipping companies; (3) design of new Ro-Ro services. The most affecting policy concerns an increase of speed of some Ro-Ro services to 22 kn, proposing a good balance between the navigation costs and the potential demand attracted.

The purpose of this study is to investigate certain aspects of a transportation choice model proposed by Krapfel and Mentzer (1982) pertaining to the influence of shipper perceptions on the selection of a mode. Specifically, this study attempts to identify the impact that shipper perceptions of intermodal and over-the-road truck service, as well as other characteristics of the shipper, have on intermodal usage. The research findings support the notion that shipper perceptions affect modal usage and indicate areas in which intermodal providers should focus their attention to improve intermodal usage.

Several studies have been conducted regarding save energy in consuming the electricity through the simple changes in routines and habits. In the case of electricity consumption, consumer behavior might influenced by several factors such as consumer profession, season, and environmental awareness. In this paper, we developed an Agent Based Model (ABM) to analyze the behavior of different agents in consuming the electricity energy for each type of profession (agent) as well as their interaction with the environment. This paper demonstrates a prototype agent based simulation model to estimate the electricity consumption based on the existing condition and some scenarios to reduce the electricity consumption from consumer point of view. From the scenario results, we analyzed the impact of the save energy to increase the electrification ratio.

The Impact

The social cost, as one of the factors determining sustainability of socio-economic development, is strongly dependent upon a number of casualties and mortality in road accidents. The condition of car tires appears to be one of the important factors determining the occurrence of accidents. The vast majority of vehicles are tested every year at vehicle inspection stations. One of the elements affecting the result of the technical condition test and basically the quality of vehicle braking is the technical condition of the tires. Their technical condition is a very important factor responsible for the quality of acceleration, braking, maintaining, or changing the direction of driving. As a consequence, it has a significant impact on road safety. The aim of the study is to examine the impact of tires on the results of tests performed at a vehicle inspection station. The study presents the results of bench measurements of the impact of selected features of tire condition of two vehicles during routine periodic inspections at a vehicle inspection station (VIS). The focus was on an attempt to assess the impact of inflation pressure, age, and tire tread wear on the braking process. The technical studies performed might be a source for legal steps assuring better management of road safety. It can also be expected that the tire choice and condition may affect fuel consumption, and therefore the amount of energy consumed by the road transport.

The Impact

To meet current targets for greenhouse gas emissions in Europe, emissions, especially those originating from the road transport sector, need to be reduced. Plans are to achieve this goal by substituting fossil fuel vehicles with electric vehicles (EVs). This article first discusses conceptually the impact of an increasing share of EVs on the electricity grid and suitable locations for charging stations with examples from a Case Study in Lower Bavaria. Secondly, the impact of purchase subsidies on EV purchases in Germany, a high-income country characterized by an important automotive industry and an increasing share of private vehicles is examined. To achieve this, yearly information on EV purchases were analyzed by applying the Synthetic Control Method. Combining data from different sources including the European Alternative Fuels Observatory, Eurostat, and the European Automobile Manufacturers' Association, an overall picture was developed. Results indicate a difference between private, semi-public, and public charging infrastructures. Its spatial distribution does not correspond to a specific development strategy. Moreover, EV subsidies have a limited effect in Germany when controlling for market size. Limiting the discussion to a trade-off between subsidizing infrastructures or EV purchases obviates the multidimensionality of the problem as neither of them may be sufficient to accelerate the transition per se. Furthermore, if electricity provided for EVs comes mainly from fossil carriers, the changes in the road transport sector will not yield the expected emission reductions. The transition towards renewables is directly intertwined with the effects of EVs on emission reductions in the road transport sector.

In recent years, the state of the road transport infrastructure in Ukraine has deteriorated significantly. With the process of urbanization and the expansion of the transport infrastructure, the ecological danger of the functioning of these strategically important objects increases, which requires effective methods of detailed study of the state of environmental components in areas of urban pollution in order to prevent negative consequences. Working with the problematic, using robots, we analyzed the methods to monitor the environmental situation around the road transport infrastructure for the development of recommendations for advancing efficiency. An algorithm for assessing the environmental situation around the objects of motor transport infrastructure is considered, based on monitoring the impact of these objects on the components of the environment and determining the main factors of this influence. The regularities and dependences of the influence of the motor transport infrastructure from the standpoint of environmental safety have been established. The indicators of pollution of the components of the environment in the study areas and methods of their production are analyzed. It has been concluded that a complex combination of chemical research methods with biodication is observable, makes it possible to analyze the effect of vehicles on various components of the environment (atmospheric air, soil and soil solutions, plants, animals, surface waters, etc.) and to establish the level of anthropogenic load.

The weaknesses of the road systems were analyzed, including dangerous events generated by vehicle getting out of the road and consequent secondary dangerous events such as: driving over a barrier or other dangerous object located next to road or roofing of the vehicle. Particularly, the security, availability of technological solutions for protection barriers, columns and road signs on roads and bridges were considered. The preventive and protective functions of road equipment and engineering objects are given, which are adequate to the specific risk. Failures of safety barriers and road protection barriers and the consequences of their failures for people, properties and the environment were analyzed. Solutions for the construction of road barriers were analyzed in terms of: availability, the degree of reliability of their components and the possibility of maintaining risk within acceptable limits. The scope of fulfillment of required functional features, design methods, modern technological solutions, test methods and certification procedures were analyzed. Functional features of protective barriers regarding: the protection level, displacements and the level of impact intensity were taken into account. Literature point of view on aided design of protective barriers has been included which covers finite element method (method of sum of displacements) with appropriate analysis of forces, torques and displacements with CAD systems including use of LS-DYNA system for events and damage parameters. A large part of the publication deals with modern technological solutions and analyzes including design of protective barriers, modeling of their elements as well as modeling collisions with vehicles, taking into account the impact of the ground.

Functioning of the enterprise management system implies collecting and analyzing information about the state of factors that threaten its economic sustainability. The sustainability of an enterprise is considered as the ability to preserve the characteristics of a business entity i.e. ensure its functioning, i.e. the success of the enterprise’s main objective function in time. The list of the most influencing factors depends on the industry affiliation of the enterprise. There has been presented the outcome of the poll of participants at the seminar devoted to upgrading skills of managerial staff of the road transport enterprises held in St. Petersburg in 2018. Studying the results of the opinion poll made it possible to conclude that the serious concern for the management of transport companies in terms of the probability of losing business stability is caused by the social and economic factors of the external environment. In order to assess the stress from the impact of economic factors there was performed a regression-correlation analysis which proved that the most significant and strong relationship between factors-indicators of sustainability can be seen in relation with such economic criteria as the inflation rate and the diesel fuel price. The net financial result and the official liquidation rate of motor transport enterprises were used as indicators of sustainability. The data obtained in the course of analysis helped to adjust the practice of managing the enterprise stability in terms of the methods used. In the present case, a special attention should be paid to the methods of managing the financial condition and methods of managing the costs of a transport enterprise, implementation of which involves the adoption of appropriate organizational and technical solutions.

One of the elements of strategy aimed at minimizing the impact of road transport on air quality is the introduction of its reorganization resulting in decreased pollutant emissions to the air. The aim of the study was to determine the optimal strategy of corrective actions in terms of the air pollutant emissions from road transport. The study presents the assessment results of the emission reduction degree of selected pollutants (PM10, PM2.5, and NOx) as well as the impact evaluation of this reduction on their concentrations in the air for adopted scenarios of the road management changes for one of the street canyons in Krakow (Southern Poland). Three scenarios under consideration of the city authorities were assessed: narrowing the cross-section of the street by eliminating one lane in both directions, limiting the maximum speed from 70 km/h to 50 km/h, and allowing only passenger and light commercial vehicles on the streets that meet the Euro 4 standard or higher. The best effects were obtained for the variant assuming banning of vehicles failing to meet the specified Euro standard. It would result in a decrease of the yearly averaged PM10 and PM2.5 concentrations by about 8–9% and for NOx by almost 30%.

The promotion of the use of public transportation is a means of solving traffic and environmental problems. In European countries, trams are a common means of public transportation. There are also some areas in Japan where new installations of trams or the extension of existing tram lines has been considered, but these plans cannot be implemented because their effects cannot be predicted. This study uses the traffic simulator MATES, which employs a multiagent model, to do a virtual social experiment on an Okayama City tram railway extension issue actually under discussion in Okayama Prefecture. It assesses the effect of a modal shift from cars to trams caused by the increase in convenience that the changes in the road structure and the extension in the railway would bring about.

Electric Vehicles (EV) adoption targets have been set by governments from countries throughout Europe, related to the European goals, for the decarbonization of the road transport sector. The change for electric vehicle technology can be challenging to EV users for a number of reasons such as battery autonomy, time to charge the vehicle, and the different driving conditions. The work in this paper aims to study how users from Madeira and Porto Santo islands deal with the challenges of EV adoption. Furthermore, this paper also studies the role of the orography in the Regenerative Braking System technology integrated into electric vehicles. To assess such information, an online questionnaire was prepared and sent out to the electric vehicle community of both islands. The main results of this study show drivers’ preference to charge the vehicles at their household and that users are satisfied with the vehicle’s technology. Also, users’ battery range anxiety did not seem to have a significant impact. Moreover, from the drivers’ point of view, there is still the need to study the role of orography, while using the regenerative braking system.
