Service quality in any sector is determined by its users, so their input must be taken into account when evaluating services. This is true for freight transport. However, as transport service quality can only be evaluated after its use and the criteria considered by customers may differ from those deemed relevant by experts, the carrier selection process is very complex. This research was conducted to provide transport service users with a simple decision making mechanism for selecting the optimal freight carrier among multiple alternatives. The model utility was assessed by applying it to a real case and comprehensive sensitivity analysis was conducted to confirm its robustness.

The increase in traffic caused by new development affects the change in traffic conditions on the surrounding roads, and shopping centres are significant traffic generators. The development of local travel generation rates and their characteristics for individual land uses from the aspect of traffic demand is a reliable way to plan traffic in order to come up with preventive solutions to traffic problems, that is, prevention of possible negative consequences on traffic conditions in the street network occurring due to the construction of shopping centres. One of the main aims of this paper is to develop a model for objective assessment of the generated traffic demand for significant changes in land use, such as the construction of shopping centres in medium-sized towns. All these would be steps in the right direction for the promotion of reliable traffic planning and adoption of TIA for every new development before a decision regarding the change in land purpose has been made. This kind of process still has not been established systematically in either Bosnia and Herzegovina and the Republic of Serbia, or in surrounding countries. This paper focuses on the formulation of a model for determining the volume of traffic generated by shopping centres in medium-sized towns in two countries of the Southeast Europe region. The survey was conducted in eight different locations (cities) where there are shopping centres with common facilities. The analysis showed that the number of visitors and vehicles attracted by the shopping centre zone can be determined by a model based on a linear regression analysis. The analysis included exploring several different factors of trip generation in shopping centres, including the relationship between trip generation and combinations of several independent variables. The verification of the model was conducted in real conditions of the traffic flow generated by a shopping centre which was not the analysis subject when forming the forecasting model. In this way, the validity of the proposed model is credibly assessed. The developed model can be applied in the procedures of planning the construction of shopping centres in medium-sized cities in the Republic of Serbia and Bosnia and Herzegovina, and wider, in the region of Southeast Europe, in order to estimate the volume of generated traffic demand, that is, its impact on the conditions of traffic on the surrounding traffic network.

U sustavu javnog gradskog prijevoza, primarni poremećaj intervala slijeđenja vozila koji nastaje unutar jednog polaska, ima tendenciju širenja u sustavu. U ovom radu analizom procesa kretanja vozila duž linije, identificirani su...

In situations when in the street network there are no separate areas for the movement of public transport vehicles, traffic conditions influence their operation and efficiency. This paper studies the influence of the volume-to-capacity...

Organization and management of Public Passenger Transport (PPT) system is a complex process, which significantly impacts the functioning of the system. Globally, there is no unique solution for organization model of PPT, but the organization models are adjusted to the characteristics of each individual area. Organization model of PPT, inherited from the self-management system of the former Socialist Federal Republic (SFR) Yugoslavia, became unsustainable in the Municipality of Inđija (Serbia) and did not fulfil transport needs and demands of passengers regarding the amount of transport and its quality in optimal manner. Old organization model has been replaced by a new modern model, based on positive experiences from developed European cities. Article presents the impact of new organization model of PPT on the work of the system. Research has been conducted in order to determine the state of both old and new system’s organization model by counting and interviewing passengers during years 2008 and 2017. In accordance with the changes made in the system, comparative analysis “before and after changes” has been done along with establishing of the effects of changes on functioning of the system and service quality. Results show significantly improved service quality, while transport demands increase by 38.3%.

Bike sharing is being popularised and promoted in many cities. The introduction of this system is a way to increase the availability and use of bicycles. As part of this paper, an overview of the existing bike-sharing systems in the area of Vojvodina was made. The possibility of introducing this system in the area of Zrenjanin was also investigated. The results of the survey conducted in Zrenjanin show that there is a great potential for the introduction of a bike sharing system in this area, but that there are many shortcomings that need to be addressed. Over 82% of respondents have a high level of bicycle use during the week, so this is an excellent indicator to support the introduction of the bike sharing system. The biggest difficulty for them when cycling is disrespect by other traffic participants, and they think that a construction of new cycling paths will contribute to an increased bicycle usage as a transport means.
