A long-standing debate among moral philosophers centers on the question of whether ignorance is always at the root of moral wrongdoing, or whether, in certain cases, wrongdoing stems from something else—namely akrasia. This paper is a discussion of how undergraduate core curriculum teachers can incorporate Augustine’s work into this debate. I begin by briefly reconstructing Socrates’ and Aristo...

Autonomous driver assistance system is a core component for the robust detection and tracking of lane markings on roads and pedestrian detection. The lane detection method is a major component of intelligent transport system. Lane detection helps to estimate the road geometry ahead as well as lateral position of vehicle. A fast lane detection algorithm is proposed by Hough transform which is fa...

Previous studies have shown that roundabouts - especially multilane roundabouts - pose accessibility challenges to pedestrians with vision impairments, in part due to a lack of yielding by drivers, especially on multilane roundabout exit legs. In this study, three different treatments are assessed in terms of their propensity for increasing driver yielding rate using a driving simulator. These ...

Recent interest in using modern roundabouts as an effective and safe method for intersection control in the United States stresses the need for accurate modeling tools. The objective of this paper is to assess the calibration potential of common analytical and micro-simulation roundabout models to operations at modern roundabouts. The models considered were aaSIDRA and RODEL (on the analytical ...

This paper develops output feedback boundary control to mitigate traffic congestion of an unidirectional two-lane freeway segment. The macroscopic dynamics are described by the Aw–Rascle–Zhang (ARZ) model respectively for both fast and slow lanes. density velocity each two lanes governed coupled 2 × nonlinear hyperbolic partial differential equations (PDEs). Lane-changing interactions between l...
