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.

Criteria Importance

Multiple actors from both private and public sectors are currently involved in the design and operation of urban passenger transport systems seeking at optimizing their own objectives. Multi-criteria decision-making (MCDM) techniques actually aid this process. In this chapter, the authors consider the problem of locating multimodal terminals of an integrated public passenger transport system (IPPTS). A case study for the city of Bogota, Colombia is evaluated. Majority of works in MCDM does not explicitly justify the choice of the applied technique. This chapter applies three different techniques, AHP (analytic hierarchy technique), ELECTRE II (elimination and choice expressing the reality), and CRITIC (criteria importance through intercriteria correlation), to solve problem. A feature of this study is that traditional economic and logistic criteria are evaluated together with environmental and social criteria not previously evaluated in the literature. Numerical results show that each multi-criteria approach may prefer a different alternative, depending on the intrinsic behavior of each technique.

Potential Area

The intense growth of cities affects their inhabitants to a considerable extent. The issues facing the traveling population include congestion and growing harmful emissions. Urban transport requires changes towards eco-friendly solutions. However, even though new forms of traveling (sharing services) are being implemented, their integration with public transport remains problematic. On account of the large number of available services combined with the absence of their integration, city inhabitants are faced with the dilemma of choosing between one or several transport modes which would enable them to make the given trip. The main goal of this article is to propose a model for integration of different transport services which could support those who intend to travel in the decision-making process. Therefore, the parameters of a model of urban sharing services were identified and classified. The parameters discussed in the paper with reference to an extensive literature review describe how individual sharing services are functioning. What has also been identified is the location-specific factors as well as those related to the potential area of operation which affect the integration with public transport. In order to take all the relevant parameters into account and find a solution to the problem at hand, a multi-criteria decision-making approach has been proposed. To this end, scores and weights determining their impact on the model have been established. For purposes of the solution in question, the relevant calculations were conducted by referring to an actual need to travel between selected locations.

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.
