Special Issue Information

Dear Colleagues,

A smart environment is an initiative that aims to realize efficient, human, and environmentally friendly, and sustainable social systems in various fields such as transportation systems, communication infrastructure, SDGs, and fintech, by utilizing advanced technologies such as IT and environmental technologies to achieve comfortable and intelligent urban living. The proliferation of smart devices has created new application areas such as the Internet of Things, industrial control and monitoring systems, and blockchain technology, which can be used to realize a sustainable society. Smart environments include interoperable objects, organizations, and arrange the exchange of information and value to support individual urban living for people at all stages of life.

The purpose of this Special Issue is to publish original, important, and visionary papers describing scientific methods and technologies that improve the efficiency, productivity, quality, and reliability of smart environments. In this Special Issue, we want to focus on understanding what needs to be done to make efficient, human, and environmentally friendly, and sustainable intelligent social systems a reality. We strongly encourage the contribution of scientific results from experts from universities and companies around the world.

The safety of vehicles is one of the major goals of driving automation. The safety distance is longer for rail vehicles such as trams because of the adherence limitations of the wheel-to-rail system. The major issues of fixed frontal sensing are fake target detection, blind spots related to rail slopes, curves, and random changes in the target’s illumination or reflectivity. In this experimental study, distance measurements were performed using a scaled tram model equipped with a LiDAR sensor with a narrow field of view, under different conditions of illumination, size, and reflectivity of the target objects, and using different track configurations, to evaluate the effectiveness of such sensors in collision-avoidance systems for rail applications. The experimental findings are underlining the sensor’s sensitivity to fake targets, objects in the sensor’s blind spots, and special optical interferences, which are important for evaluating long-range LiDAR capabilities in sensing safety distance for vehicles. The conclusions can help developers to produce a dedicated colliding prevention system for trams and to identify the zones with high risk in the track where additional protection methods should be used. The LiDAR sensor must be used in conjunction with additional sensors to perform all the security tasks of an anti-colliding system for the tram. Full article
