A safe and connected transport infrastructure is essential in increasing traffic safety and capacity, creating a more efficient transport system. The behavior of pedestrians and cyclists, driving speeds on roads, the environment, these are all elements that significantly affect traffic safety. Research has shown that traffic accidents are one of the most common causes of death for children, so special attention should be paid to vulnerable road users. Pedestrians and cyclists comprise the largest range of traffic users from children to the elderly with different cognitive and motor abilities, and also include users with various difficulties (disabled, blind and partially sighted people, etc.), so it is necessary to pay special attention in the design of traffic infrastructure intended for these users. Conflict zones between different forms of traffic, where motorized and pedestrian traffic interact and where pedestrian attention and reaction time are two elements that significantly affect safety, represent critical segments of the traffic infrastructure. For the analysis of the selected segment of the traffic network, the traffic light intersection Vukovarska ulica - Zagrebačka ulica of the primary network was chosen due to its proximity to the Osijek Health Center and the large concentration of elderly and infirm people and the short duration of the green light for pedestrians and cyclists. The intersection of the secondary network Frankopanska ulica - Sjenjak was also analyzed due to its close proximity to Fran Krsto Frankopan Primary School, where children move every day. The reduction of conflicts between motorized and non-motorized traffic includes the creation of variant solutions to the existing situation by applying a central island, where proper planning and arrangement of the traffic infrastructure can reduce conflict points and improve the safety. For each observed location, variant solutions were created for the reconstruction of traffic areas by introducing a central island with the aim of increasing the safety of pedestrian flows. Using the VISSIM microsimulation program, intersection reconstruction models were created, and on the basis of the obtained simulation results, an analysis of variant solutions and evaluation of the effectiveness of the central island as a measure to increase traffic safety was performed.
