Network Safety

The complex analysis of traffic system safety in Nigeria based on qualitative and simulation modeling was performed. These models allow us to perform a preliminary assessment of measures aimed at safety improvement of the traffic system situation in Nigeria, and to make projections to improve the parameters of the transport system. In this paper, the results of the system analysis of the transport network safety in Nigeria based on qualitative and simulation modeling are presented. The qualitative model of transport network safety and the model of system dynamics is developed, the safety measures based on simulation are suggested. The obtained results could be used for support of decision making in the field of transport network management in Nigeria. The experiments were conducted on qualitative models, they showed the effect on the transport system parameters of such measures: increasing fines for violations of the road regulations and increasing of the funding of the road repairing and construction. The support organization in decision-making in the management of the urban transport system development is very important. This problem can be solved with the use of different approaches. The use of qualitative and dynamic-system modeling for complex analysis of the transport system and evaluation of measures effectiveness aimed at improving its safety is proposed in this paper.

Development Scenarios

The paper describes the assessment of 3 Vilnius city development scenarios according to transport system parameters multi‐criteria analysis and performing transport system modelling for 2015 and 2025 years. Vilnius city development scenarios such as concentrated development, extensive development and decentralized concentrated development have been evaluated from a transport viewpoint. Vilnius city development scenarios have been evaluated by using SAW (Simple Additive Weighting) multi‐criteria method. According to this method development scenarios ranking calculations have been performed using transport system indicators. Urban transport system analysis model was developed for Vilnius conditions, which estimates the fuel consumption, average travel distance and driven time by car in morning peak hours depending on urban areas development scenario and socio‐economic data. This model should be used when calculating new projects of the transport infrastructure (by‐passes, new bridges) and when evaluating the economic efficiency of traffic organization projects. Santrauka Straipsnyje analizuojami trys susisiekimo sistemos požiūriu Vilniaus miesto plėtros scenarijai. Miesto plėtros scenarijai, kaip sutelktoji plėtra, decentralizuotai sutelktoji plėtra ir ekstensyvioji plėtra, vertinami daugiakriteriu metodu SAW ir atliekant Vilniaus miesto plėtros scenarijų modeliavimą 2015 m. ir 2025 m. Daugiakriteriu metodu nustatoma plėtros scenarijų prioritetinė eilė, vertinant Vilniaus miesto susisiekimo sistemos rodiklius. Modeliuojant plėtros scenarijų, nustatomi tokie rytinio piko metu rodikliai: kuro naudojimas, suminis nuvažiuotas atstumas, suminis kelionės laikas. Modeliavimas remiasi esamais ir numatytais bendrojo Vilniaus plano miesto gatvių tinklo duomenimis, transportinių rajonų dabartiniais ir prognozuojamais socialiniais bei ekonominiais duomenimis. Sukurtas modelis gali būti sėkmingai naudojamas vertinant transporto infrastruktūros ir eismo organizavimo projektų įtaką miesto susisiekimo sistemai.

The Impact

Object of study - the impact of the transport system on economic security. Applied research and calculations are performed on the example of the Lipetsk region (Russia). The study used methods of system analysis, performance evaluation, statistical method, calculation of Engel and Uspensky coefficients, etc. Analysis of data on the provision of transport infrastructure in the regions of Russia and other countries showed that insufficient development of transport is a “weak spot” in Russian regions. To solve it, the following measures were proposed: development of public urban transport, modernization of the integrated transport system of urban agglomerations, introduction of a strategic approach to managing transport development, construction of toll roads and highways, more active use of electronic control systems for urban transport systems. To assess the effectiveness of the development strategy of urban transport systems, the authors suggested using a number of criteria. This is a criterion of fiscal efficiency; environmental performance criterion; criterion of strategic coherence. Their use allows optimizing the development of transport in Russian cities. As a result, the economic security of their development will be reliably ensured.

Simulation Time

Subway plays an important role in urban transport system. Fire as the major risk of the subway, is gaining increasing concern. In this study, fire simulation is performed to estimate fire safety of different compartments of the subway train. Result shows that the two compartments in the middle become dangerous at 150s and the compartments in the two ends are not safe at 300s approximately. The other two compartments are always safe during the simulation time.
