Abstract


Road markings are integral to effective traffic management, serving as visual cues for drivers and essential components in ensuring road safety. Choosing materials for road markings, whether durable options like plastic materials or conventional paint, presents an important decision point in road infrastructure planning. While durable materials offer long-lasting benefits, paint provides a flexible and cost-effective alternative. Visibility is a critical factor, particularly in low-light conditions, highlighting the crucial role of retroreflection. This research compares the performance of road markings made from durable materials with those made using paint. Research focuses on the Republic of Croatia, analysing road markings across its network of state roads based on available data categorised into five regions. Descriptive statistics will provide insights into the materials used for exploiting road markings across five regions. This research compares the retroreflection of refurbished road markings and post-exposure retroreflection over an annual cycle. The reference year spans from the autumn of one year to the spring of the following year, accounting for winter road maintenance and road marking renewal periods. Statistical analysis employs the One-way ANOVA (analysis of variance) to compare the visibility of road markings in use and the renewed road markings based on the materials used. This analysis provides insights concerning road marking material retroreflection and its degradation depending on traffic exposure and environmental conditions. The results are compared to determine if there is a substantial difference in retroreflection between the two used road marking materials. Data analysis is conducted using the SPSS statistic tool. Findings of this research will help provide insights into the balance between the visibility of road markings based on used materials over time, offering a valuable perspective for road maintenance strategies.
