Evaluation of Raised Pavement Markers

Task Order 328In the State of New Jersey, raised pavement markers (RPMs) are used along all centerlines and skip lines, regardless of traffic volume, roadway geometry, or roadway classification. The extensive use of RPMs has raised interest in understanding 1) whether this significant investment generates variant safety benefits at different locations; 2) whether there are alternatives or modifications to the existing RPMs; and 3) how to optimize the installation, monitoring, and maintenance of RPMs and their promising alternatives in order to attain a more cost-effective safety improvement. This study reviewed the relevant literature and provided a methodological framework for quantifying the safety effectiveness and implementation costs of RPMs and their alternatives given specified road and traffic characteristics. A luminance measurement method was developed to allow researchers to estimate the luminance of these devices and to compare different reflective pavement markers and their alternatives regarding the ability to provide visual delineation. The study also analyzed the installation practices in various states and proposed guidelines for the use of RPMs and relevant alternatives accounting for various road classification, geometry, and traffic factors. Finally, the study developed a computer-aided decision support tool that can be used to calculate the life cycle cost of RPMs and other alternatives, thereby supporting decisions with respect to the optimal use of safety investment

Substructured multibody molecular dynamics.

We have enhanced our parallel molecular dynamics (MD) simulation software LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator, lammps.sandia.gov) to include many new features for accelerated simulation including articulated rigid body dynamics via coupling to the Rensselaer Polytechnic Institute code POEMS (Parallelizable Open-source Efficient Multibody Software). We use new features of the LAMMPS software package to investigate rhodopsin photoisomerization, and water model surface tension and capillary waves at the vapor-liquid interface. Finally, we motivate the recipes of MD for practitioners and researchers in numerical analysis and computational mechanics

Maximizing Pedestrians\u2019 Perceptions of Safety Using Light Source Spectrum

As part of its study for the Region 2 University Transportation Research Center (UTRC) at the City University of New York, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute conducted human factors studies to investigate responses to light sources having different spectral (color) compositions and to develop a model to predict perceptions of brightness and, therefore, of safety and security under roadway lighting conditions

Lexicalization and compositionality of emoji

Emoji have been ubiquitous in communication for over a decade, yet how they derive meaning remains underexplored. Here we examine two aspects fundamental to linguistic meaning-making: the degree to which emoji have conventional lexicalized meanings (Experiments 1 & 2) and whether their combination allows for compositional meaning-making in linear strings compared to spatial pictures (Experiment 3). Experiment 1 established that participants have a range of agreement for the conventional meanings of emoji. Across Experiments 2 and 3, we measured accuracy and response times to word-emoji pairings in a match/mismatch task. In Experiment 2, we found that accuracy and response time both correlate significantly with the level of population-wide meaning agreement, suggesting that lexical access of single emoji may be comparable to that of words. In Experiment 3, however, presenting emoji-only expressions in a linear, written language-like sentence order incurred a processing cost compared to presenting the same expressions in a nonlinear analog depiction. Altogether, these findings suggest that emoji can allow a range of stored, lexicalized representations, yet they remain constrained in their combinatorial properties
