“…Their visibility in vehicles' headlights is achieved by retroreflectivity, expressed as a coefficient of retroreflected luminance (R L ) and measured in mcd/m 2 /lx [51]. In a recent field experiment, it was demonstrated that high R L of road markings under both dry and wet conditions increased driver comfort, particularly for elderly drivers [23]. Even though there might be doubts regarding the correlation of safety benefits and high R L [31], they were quantified based on statistical analyses of crashes between intersections, on unlit rural roads at night time: an increase of up to 23% in single-vehicle accidents at that conditions could be correlated with a decrease in R L by 100 mcd/m 2 /lx [18].…”

“…This type of glass beads can provide R L in white paint, under field conditions, of approximately 400 mcd/m 2 /lx. Because higher R L was reported as advantageous [18,23,35], a premium type of glass beads was developed and commercialised [7,13]. The premium beads are reported as being prepared from virgin raw materials in a proprietary process and are characterised by RI increased to 1.6-1.7, very high roundness and exceptional surface quality, minimised air inclusions, and improved resistance to scratching.…”

Introduction: On majority of roads, horizontal road markings are essential safety feature that must be periodically renewed to maintain appropriate performance. Results: The use of a premium road marking system resulted in prolonged the service life as compared to a standard system, which would be financially-neutral in the long term despite much higher unit and initial costs; advantageously, 54% less glass beads and 63% less paint would be required over 10-year life cycle. When these products usage savings are recalculated into raw materials consumption, the premium system would demand about 21% more of titanium dioxide, but that would be offset by approximately 25% reduction in the consumption of acrylic resin and circa 97% reduction in organic solvents usage and emissions. Conclusions: The results from this analysis can be used by road administrators to select the best systems, by policy makers seeking minimisation of environmental impacts, and by contractors who won performance tenders.

“…Studies have shown that when the marking retroreflectivity coefficient is increased by 10-100 mcd, the traffic risk is reduced by up to 0.9~8.6% [10]. Therefore, road markings can only have excellent daytime visibility and nighttime reflective performance to play a good role in declining the probability of accidents and vehicle congestion [11].…”

Road marking is very important for driving safety and reducing the accident rate as a basic component of highway construction. However, traditional road marking paints are prone to be worn after short-term application and have poor durability and reflective performance. To address these problems, the marking paint was modified using the organic polymer material polytetrafluoroethylene to create a durable hydrophobic hot-melt marking paint. The factors affecting the reflective performance of marking lines are analyzed, and artificial accelerated abrasion tests were carried out to analyze the skid resistance and marking retroreflection coefficient of hydrophobic coatings. Results show that the texture of the glass beads and the quality of the coating plays a major role in the reflective performance of the marking line. The friction coefficient value of the modified marking paint is 4.62% higher than that of the traditional hot-melt marking paint. The retroreflection performance of the marking paint with 4% hydrophobic material is 8.45% higher than the initial value of the retroreflection coefficient of the traditional hot-melt marking paints. This sustainable hydrophobic hot-melt marking paint is safer and more durable than traditional pavement marking paints, which may save follow-up maintenance resources and cost from the sustainable aspect.

“…Road factor contributes 3% of accidents and increases to 34% when combined with other factors such as human factor and vehicle factor [3]. Geometric design of roads that do not comply with the standard [4]- [7], damaged road surface conditions [8], [9], dangerous roadside [10]- [12], unavailable and/or damaged street lighting [13], [14], unavailability of markers and low visibility of markers [15], [16] inappropriate signs [17], and pedestrian facilities that do not adequately function [18], [19] are some of the factors that cause traffic accidents from road infrastructure aspect.…”

There were 100,106 cases of traffic accidents that occurred in Indonesia in 2013, in which 26,416 people died, 28,438 people were seriously injured, and 110,448 people were mildly injured. Road infrastructure is one of the components of traffic safety. If it is not planned, designed, built and maintained properly, conditions such as poor geometry, damaged and unmaintained pavement surfaces can cause traffic accidents. Understanding of risk factors for road infrastructure accident and weighting of factors are an important step in increasing traffic safety. In addition, limited data on accidents in Indonesia also pose an obstacle in evaluating accidents. This study aims to weight risk factors for road infrastructure accident without accident data using the analytic hierarchy process (AHP) method. 40 respondents consisting of academics, practitioners, and stakeholders participated in filling out questionnaires on assessing risk factors for road infrastructure accident. The weighting results using AHP indicated that the priority ranking of accident risks from the largest to the smallest were road surface conditions, geometric conditions, road equipment, roadside hazard and road complementary buildings respectively. This study was limited to two-way, two-lane undivided urban road (4/2 UD) on straight and flat segments. Other segments and types of roads needs to be used because different types of roads have different risk factors and weights. The AHP method was used at the weighting phase without the process of assessing the existing road infrastructure.
