Title Real-World Demonstrations of Novel Pedestrian Crosswalk Lighting Type Journal Article
Year 2017 Publication Transportation Research Record: Journal of the Transportation Research Board Abbreviated Journal Transportation Research Record: Journal of the Transportation Research Board
Volume (down) 2661 Issue Pages 62-68
Keywords Lighting; Public Safety; Planning
Abstract Outdoor urban pedestrian lighting serves multiple purposes and should do so in the most efficient and economic manner. An important purpose of outdoor urban pedestrian lighting is to support the safety of pedestrians, particularly those who interact with adjacent vehicle traffic, while enhancing pedestrians’ perceptions of personal safety and security. A review of published literature, as well as the demonstration activities summarized, indicates the potential for bollard-level crosswalk lighting to enhance pedestrian visibility and to improve safety at crosswalks, particularly at locations where the presence of a crosswalk might not be expected by approaching drivers. Such locations include midblock crossings, roundabouts, and locations near schools and other public venues that might experience high levels of pedestrian traffic at sporadic or unexpected times.

Title Human Factors Impacts of Light-Emitting Diode Airfield Lighting Type Journal Article
Year 2017 Publication Transportation Research Record: Journal of the Transportation Research Board Abbreviated Journal Transportation Research Record: Journal of the Transportation Research Board
Volume (down) 2626 Issue Pages 51-57
Keywords Lighting
Abstract Light-emitting diodes (LEDs) differ from incandescent light sources in several ways that are relevant to energy and maintenance requirements of airfield lighting systems. They have higher luminous efficacy and, when designed properly, have longer useful operating lives; both factors make LEDs attractive candidates for airfield lighting. The photometric, colorimetric, and temporal characteristics of LEDs also differ from those of incandescent light sources, and these can have important implications for the appearance of runway and taxiway lighting systems. The present paper reviews publications summarizing experimental and analytical investigations designed to assess these implications with respect to the following human factors impacts: color identification, brightness and glare, visibility in fog and haze, response to onset of flashing lights, and stroboscopic effects such as the phantom array. Overall, this review of experimental evidence suggests that, in addition to their reduced energy use and maintenance requirements, LED airfield lighting can be advantageous in comparison with incandescent lighting systems used to delineate airport runways and taxiways.

Title Assessment of an Adaptive Driving Beam Headlighting System: Visibility and Glare Type Journal Article
Year 2016 Publication Transportation Research Record: Journal of the Transportation Research Board Abbreviated Journal Transportation Research Record: Journal of the Transportation Research Board
Volume (down) 2555 Issue Pages 81-85
Keywords Lighting
Abstract Recent developments in solid-state lighting, sensor, and control technologies make new configurations for vehicle forward lighting feasible. Adaptive driving beam (ADB) systems build on systems that automatically switch from high- to low-beam headlights in the presence of oncoming vehicles. ADB systems can detect oncoming headlights and preceding taillights and reduce their intensity only in the direction of the other lights, while they maintain higher levels of illumination throughout the remainder of the field of view. The nominal benefit of ADB systems is the provision of high-beam levels of illumination in the forward scene, while glare is reduced to oncoming and preceding drivers, who perceive low-beam illumination levels. In this study, two dynamic field experiments were conducted: one experiment measured the ability of observers to identify the walking direction of roadside pedestrian targets with and without the use of the ADB system; the other experiment evaluated the discomfort glare elicited by the ADB system compared with the glare from conventional low- and high-beam headlights. The findings from both experiments were consistent with previous analytical and static field tests and suggested that ADB systems can offer safety benefits beyond those offered by conventional headlight systems.

Title Quantifying Urban Sprawl and Its Driving Forces in China Type Journal Article
Year 2019 Publication Discrete Dynamics in Nature and Society Abbreviated Journal Discrete Dynamics in Nature and Society
Volume (down) 2019 Issue Pages 1-14
Keywords Remote Sensing
Abstract Against the background that urbanization has proceeded quickly in China over the last two decades, a limited number of empirical researches have been performed for analyzing the measurement and driving forces of urban sprawl at the national and regional level. The article aims at using remote sensing derived data and administrative data (for statistical purposes) to investigate the development status of urban sprawl together with its driving forces. Compared with existing studies, NPP/VIIRS data and LandScan data were used here to examine urban sprawl from two different perspectives: urban population sprawl and urban land sprawl. Furthermore, we used population density as a counter-indicator of urban sprawl, and the regression results also prove the superiority of the urban sprawl designed by us. The main results show that the intensity of urban population sprawl and urban land sprawl has been enhanced. However, the upside-down between the inflow of migrants and the supply of urban construction land among different regions aggravates the intensity of urban sprawl. According to the regression analyses, the driving mechanism of urban sprawl in the eastern region relying on land finance and financial development has lost momentum for the limitation of urban construction land supply. The continuous outflow of population and loosely land supply have accelerated the intensity of urban land sprawl in the central and western regions. The findings of the article may help people to realize that urban sprawl has become a staggering reality among Chinese cities; thereby urban planners as well as policymakers should make some actions to hinder the urban sprawl.
