When defining criteria that have an influence on traffic accessibility in suburbs, it is necessary to take into account the specificity of a concrete urban unit. In existing scientific papers, the authors have dealt with the impact of the remoteness of settlements and their accessibility from the city center. The main aims of this paper are to define and quantify the criteria that have the greatest influence on traffic accessibility in suburban areas, that is, to develop a model of traffic accessibility. This model refers to traffic accessibility in suburban areas, where an urban public transport system is operational and represents a qualitative approach to research. Research has shown that factors such as a network of public transport (PT) lines, a network of accessible roads in a settlement, travel time, and timetables are of great importance in the description and generation of a new model. This model was tested in 23 suburban districts with regard to the needed walking time. The Fuzzy AHP (FAHP) method, one of the most popular methods for multi-criteria decision making, was used. Based on the results presented in this paper, it is expected that the application of this model will enable development and sustainability in suburban areas, as well as greater social equality and involvement of dwellers (especially the younger generation) in social activities, in view of achieving a better quality of life.

The number of taxi stands as well as their spatial distribution on the territory of the city have a great influence on the accessibility, i.e. the availability to users of taxi transport of passengers. The locations of taxi stands on the territory of each City are determined by the City Council of the City. In order to determine the optimal location and number of taxi stands in an area, the paper proposes a methodology for determining the location and number of taxi stands. An analysis of the location and functionality of taxi stands was performed on a case study in the territory of the City of Leskovac, and based on the conducted research, a methodology proposal was made for determining the optimal number and capacity of taxi stands with the function of spatial distribution of taxi stands in an area.

One of the key issues of the effectiveness of road transport companies (RTC) that deal with the transportation of goods is the increase in the productivity of the vehicle fleet. Existing models that measure productivity are based on the analysis of one or two independent variables affecting the productivity of freight vehicles. The paper presents a new model for optimizing the productivity of the rolling stock as a function of two operational and technical parameters, through which it is possible to determine their influence on the optimal increase in productivity. The model will be verified on a case study – an example of a repetitive transport route. An analysis of the influence of all pairs of parameters is presented, based on which the maximum value of vehicle productivity on the observed transport route was obtained.
