Many studies have addressed this parameter, especially the impact of increasing or decreasing speed limits on traffic flow. Changing the speed limit from 120 km/h to 130 km/h on motorways in the Republic of Serbia has caused a lot of attention. The aim of this paper was to analyze this change from several important aspects. Based on the traffic counter data, a speed analysis was performed according to a realistic and hypothetical scenario for the past few years. The hypothetical scenario shows what would happen with the speed if the limit in the observed years was 130 km/h. Also, the analysis of compliance of technical -exploitation characteristics of the state road A1 with the legal and technical standards related to the speed of 130 km/h was performed. Finally, a field survey using an android application and a moving observer method showed how the new speed limit affects traffic flow, that is, the dispersion of speed in flow and the average speed of movement.
