Abstract

Applications of adaptive and intelligent lighting technologies such as presence sensitive lighting, potentially offer solutions for reducing the energy consumption of road lighting while maintaining user comfort and safety. However, little is known about road users’ experiences of such lighting. To address this gap, we conducted a real-world case study of a presence sensitive roadway lighting on a collector road in a housing area in southern Finland. New, controllable LED lighting with PIR (passive infrared) presence sensors was implemented along the road, and test scenarios were designed, programmed, and tested. The lighting was adapted both to motor vehicles using the road and to the measured traffic density along it. Drivers’ experiences and attitudes toward the lighting were collected in a three-phase evaluation with questionnaires from the community of about 1000 households using the road as part of their daily mobility. The results indicate that as an experience, presence sensitive lighting in a road environment was at least as positive as traditional, uncontrolled lighting. User experiences of presence sensitive lighting did not differ from the experiences of uncontrolled lighting regarding pleasantness, uniformity, glare, and road visibility. Most of the drivers (86%) did not notice any dynamic change in the lighting. When informed about the tested lighting strategies, most of the participants (72%) would prefer either one of the intelligent lighting modes to be the permanent lighting solution. The results of this exploratory, real-world study point towards the potential feasibility of this technology from a user experience perspective, as the experienced stability of the lighting was unaltered in the tested scenarios; importantly, it also highlights the need to study adaptive roadway lighting further, especially through confirmatory studies in controlled settings.

驾驶员对存在敏感照明点的经验和知情意见——兼论在道路环境中引入自适应照明的可行性
自适应和智能照明技术的应用,如存在感照明,有可能提供降低道路照明能耗的解决方案,同时保持用户的舒适性和安全性。然而,人们对道路使用者的这种照明体验知之甚少。为了解决这一差距,我们对芬兰南部一个住宅区的集流道路上的存在敏感道路照明进行了真实世界的案例研究。道路沿线实施了带有PIR(无源红外)存在传感器的新型可控LED照明,并设计、编程和测试了测试场景。照明既适用于使用道路的机动车,也适用于测量的道路交通密度。在一项分三阶段的评估中,收集了驾驶员对照明的体验和态度,并从约1000户使用道路的家庭中进行了问卷调查,这是他们日常出行的一部分。结果表明,作为一种体验,道路环境中的存在敏感照明至少与传统的、不受控制的照明一样积极。在舒适性、均匀性、眩光和道路能见度方面,存在敏感照明的用户体验与不受控制的照明的体验没有差异。大多数驾驶员(86%)没有注意到照明的任何动态变化。当被告知测试的照明策略时,大多数参与者(72%)更喜欢其中一种智能照明模式作为永久照明解决方案。这项探索性的真实世界研究的结果从用户体验的角度指出了这项技术的潜在可行性,因为在测试场景中,照明的体验稳定性没有改变;重要的是,它还强调了进一步研究自适应道路照明的必要性,特别是通过在受控环境中进行验证性研究。

期刊介绍: Smart Cities (ISSN 2624-6511) provides an advanced forum for the dissemination of information on the science and technology of smart cities, publishing reviews, regular research papers (articles) and communications in all areas of research concerning smart cities. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible, with no restriction on the maximum length of the papers published so that all experimental results can be reproduced.
