Investigating the road safety management capacity: Toward a lead agency reform

An efficient management system and leadership body is one of the key requirements for a road safety improvement program. In low- and middle-income countries, the organizational structure of the management system may suffer from deficiencies weakening the institutional functions across key road safety players. Hence, it is necessary to form an inner- and inter-organization evaluation framework encompassing all the processes, events, dependencies, and causation among road safety players. In this paper, a (three-stage) system thinking approach is developed to evaluate the behavior of inter-organizational complex system and to determine major deficiencies in the role of the road safety lead agency. The first stages of the system thinking approach starts with drawing diagrams (i.e. multiple-effect and multiple-criteria trees) that allows identifying the chains of reasoning behind events or consequences. The next stage of the system thinking approach embodies the analytic network process (ANP), an advanced multi-criteria decision-making technique, which handles the lead agency capacity evaluation and helps to determine how and by what magnitude any of the players can affect the national road safety. The proposed method applies to the case of Iran, a middle-income developing country in the Middle East. Since in Iran, the Road Safety Commission (RSC) has been established as the lead agency, it was expected that RSC owns the greatest influence on the status of road safety. However, our results show that the overall influence of RSC on road safety is far less than what was expected. Subsequently, a supplementary procedure is proposed to specify institutional reforms in order to avoid such organizational inefficiencies.

Lateral dynamics of motorcycles towing single-wheeled trailers

A motorcycle towing a single-wheel trailer may provide useful transport for light cargo on narrow tracks and off-road use, particularly in rural areas of developing countries. Four designs of such trailers are described. Linear models are derived for the lateral dynamics of an off-road motorcycle towing this type of trailer straight ahead at constant speed. The trailers were tested behind an instrumented motorcycle. Linear autoregressive models were fitted to the experimental data using system identification techniques. Analytical and experimentally derived models largely agreed on frequency, damping and shape of the weave, wobble and trailer sway normal modes. The trailers made the motorcycle’s steering heavier but the analytical models did not predict this. The location of the articulation axes between the motorcycle and the trailer were found to be critical for stability. The best trailer design handled well with loads up to 200 kg and speeds up to 70 km/h.

论船舶登记中的"真正联系"原则

为了改变方便旗船舶管理与控制难的问题,人们提出船旗国和船舶之间要确立“真正联系”原则。本文对“真正联系”原则的提出、对该原则的发展做出简单描述；对“真正联系”原则三要素进行详细分析,指出要符合三个事实：船旗国内的船公司至少有本国的代表或管理人的事实、在船舶所有权上船旗国应有资金参与的事实、船旗国应配备本国船员在其船上工作的事实。
