Quality of service in urban surface transit has a great impact on sustainable urban mobility, with travel time being one of the most important indicators of service reliability. But urban surface transit is prone to many disturbance factors causing travel time discrepancy and variability, making transit less reliable for passengers. We conducted research in the City of Zagreb on a single tram line by splitting it into constant-frequency segments. The first phase was modeling minimum segment travel times to base the indicators and predictors upon, and the second phase was establishing correlation matrices between the predictors and travel time using Pearson correlation coefficients and significance. Variance inflation factors were used to check for collinearities. While predictors belonging to the transport supply irregularity group did not have an impact, the ones belonging to the disturbance factors group showed correlation, with six of them being significant. This research in rarely represented tram transit determined the most significant disturbance factors rich in traffic context that can be used to develop travel time prediction models.

The liberalization of the taxi market in 2018 in the Republic of Croatia has resulted in an increase in the number of taxi vehicles on the roads. In coastal tourist centres, the demand for taxi transportation increases during the summer months. In order to meet the transport demand, taxi carriers with licenses have arrived from the continental cities to coastal cities. The paper will investigate the extent to which continental taxis affect congestion and the overall structure of the traffic flow. The purpose of the paper is to define a methodology for calculating the share of taxi vehicles in the traffic flow, which will allow their distinction according to registration marks. The aim of this study is to examine the proportion of vehicles with non-domiciled plates in the centres of the tourist cities of Dubrovnik and Split.

Road safety is a crucial component of the sustainable mobility, which is additionally emphasized by the fact that road safety improvements are on the political agenda of the European Commission. Road transport is the most vulnerable traffic mode, and in densely populated urban areas road accidents occur more frequently because of higher number of conflicts among traffic participants using different modes. This paper provides a detailed analysis of road safety in the Municipality of Brdovec. The data used in the analysis was provided by the ministry of interior in charge for 2018 to 2023, to give an insight into the current state. Then the paper focuses on road accident analysis considering time, location, and participants as inputs, providing the results in form of indicators – locations of increased risk and contributing factors. The goal of the analysis is to develop recommendations and strategies to improve road safety in the Municipality of Brdovec based on the provided indicators, as well as preventive measures for infrastructure improvements leading to better road safety.

A sound parking policy is crucial for sustainable urban mobility. Since mostly fixed public garage supply often makes up a significant proportion of urban parking supply, matching it to demand becomes a challenge. This paper researches the impact of changes in parking pricing on key parking performance characteristics in urban garages. Compared to previous research, this paper focuses on user composition for daily parking with data obtained from parking system management. For the study area, two public garages in the City of Zagreb were chosen. This paper offers a solution for managing garage parking in urban areas sustainably. Based on user composition and key parking performance characteristics, this paper argues for introducing dynamic parking pricing based on occupancy. The results of analysing key parking performance characteristics and user composition showed that the impact of price changes affects the observed public garages differently. Based on the analysis, solutions will be able to be offered for a more rational urban parking policy.
