On The Road

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.

Framework Conditions

About 36% of fatal road accidents in Norway involve at least one driver who is “at work”. It has been argued that the implementation of rules clearly defining the responsibility of road transport companies to prevent work related accidents, by implementing safety management systems (SMS), could lead to increased safety. In the present study we tested the validity of this suggestion, by examining the influence of different sector rules on work-related accident prevention in Norwegian road and maritime transport. In contrast to the road sector, the maritime sector has had rules requiring SMS for over 20 years, clearly defining the shipping companies responsibility for prevention of work-related accidents. The aims of the study were to: (1) examine how the different sector rules influence perceptions of whether the responsibility to prevent work-related accidents is clearly defined in each sector; and (2) compare respondents’ perceptions of the quality of their sectors’ efforts to prevent work-related accidents, and factors influencing this. The study was based on a small-scale survey (N = 112) and qualitative interviews with sector experts (N = 17) from companies, authorities, and NGOs in the road and the maritime sectors. Results indicate that respondents in the maritime sector perceive the responsibility to prevent work-related accidents as far more clearly defined, and they rate their sector’s efforts to prevent accidents as higher than respondents in road. Multivariate analyses indicate that this is related to the scope of safety regulations in the sectors studied, controlled for several important framework conditions. Based on the results, we conclude that the implementation of SMS rules focused on transport companies’ responsibility to prevent work-related accidents could improve safety in the road sector. However, due to barriers to SMS implementation in the road sector, we suggest starting with a simplified version of SMS.

The work, based on previously little available for research, as well as materials and documents found in archival institutions, reflects the legal basis for ensuring road safety in 1948-1953, the state and organizational and legal measures taken in the field of combating accidents in road transport at the republican level by the example Ukrainian Soviet Socialist Republic. Attention is focused on the key problems that determine the development of the road safety system, the measures taken, their effectiveness, mistakes and achievements. Measures to counteract accidents in vehicles are investigated from a historical and legal standpoint, a critical and detailed analysis of decrees and orders of the government, departmental regulatory legal acts. It was found that the presence of a significant number of administrative decisions of the republican authorities of Soviet Ukraine, although it was a rather progressive step for its time, did not fully take into account the reality of achieving the set goals, local conditions and peculiarities. At the same time, the functioning of the emerging road safety system was significantly hampered by the lack of a unified national policy in the context of the rapid growth and development of the country’s automobile and road complex.

Costs involved in double-bottoms (tandem trailers) and TOFC (trailer-on-flatcar; piggyback) were modeled and compared with conventional over-the-road transport of bulk milk from northern Vermont in single trailers. Both modes were found to be both cost-effective and fuel-sparing alternatives to conventional transport.Since the study's completion, although not as a direct result of it, two shippers have adopted these innovations. One of them (using double-bottoms) has budgeted savings even larger than those claimed in our study.
