Abstract: Most existing pavement maintenance and rehabilitation (M&R) decision-making approaches ignore the length constraint of preventive maintenance (PM). This study proposed a practical optimization-based decision-making ...

Abstract: The current method of computing the minimum pedestrian green interval for intersection signal timing assumes that the component variables are deterministic. This paper presents a probabilistic method in which the pedestrian ...

Abstract: This research investigated the size effect of hydrated lime on the moisture susceptibility of warm-mix-asphalt (WMA) mixtures with selected additives. A superfine hydrated lime used in the study was produced from regular ...

Abstract: Light detection and ranging (LiDAR) data provide a rather precise depiction of the real three-dimensional (3D) road environment and have been used by some researchers to produce more precise available sight distance (ASD) ...

Abstract: Two principal aspects of preliminary highway design are detailed characterization of the geographic and topographic features along potential candidate alignments and preliminary design of the highway along at least one of ...

Abstract: Due to the effects of low-pressure and hypoxic environments at high altitudes, drivers in high-altitude areas exhibit increased perceived reaction times, leading to challenges in accurate speed estimation and handling ...

Abstract: The unique natural geographic environment at high altitudes, characterized by low partial pressure, significantly reduces blood oxygen levels and affects human systems. These impacts directly influence drivers’ psychophysiological ...

Abstract: Periodic measurements of sight distance on as-built roads and subsequent removal of sight obstructions are important for guaranteeing highway safety. In this paper, an accurate and efficient framework is proposed for ...
