“…Some researchers used driving simulators to analyze drivers' speed behavior on ramp curves and curves on two-lane rural roads (Bella, 2009;Calvi, 2015;Montella, Galante, Mauriello, & Aria, 2015), where the latter was most frequently subject of research. For example, Calvi (2015) conducted a driving simulator study utilizing the Inter-University Research Centre for Road Safety (CRISS) to evaluate the effects of different curve features on driving speed and lateral positions (trajectories) along a curve on rural roads.…”

On interchanges there are higher probabilities of risky situations compared to uninterrupted motorway sections due to increased speed variability and higher frequency of lane-changes. In this study, we focus on understanding and modelling drivers' longitudinal speed behavior when negotiating horizontal ramp curves in interchanges in the Netherlands. For this purpose, detailed trajectory data of free-moving vehicles on 29 different curves from 6 different interchanges were collected from video images taken from a hovering helicopter. Only free-moving vehicles were chosen in order to understand how the road geometric design affects the (unhindered) driving speeds. The results of the speed profiles analysis show that for each connection, the speed profiles follow certain patterns, despite the large heterogeneity among drivers. These speed patterns were found to be significantly affected by the distance along a connection, the design characteristics of a connection, vehicle type, and drivers' heterogeneity. The impact of the distance along the connection on the speed was found to be significant and non-linear. This indicates that drivers do not maintain constant speeds, but adapt it along the connections. These models, which describe drivers' speed behavior and adaptation along different connections, are useful for improving current speed behavior models used in different microscopic simulation packages, and provide designers with a tool to estimate the speeds during the design process. The insights from this study, and the identified models, are also useful for enhancing the acceptability of automated vehicles' longitudinal behavior by adapting it to human like behavior.

“…Horizontal road markings are common features seen on almost all modern roads. They serve as guidelines for the drivers, helping them in remaining in their travel paths [17,22,44]. In addition, horizontal signalisation in form of solid, dashed, or colourful lines and symbols informs the drivers about oncoming dangers and rules of the road.…”

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.
