Abstract

In the case of an accident, a prompt response is needed to prevent accidents or provide assistance to traffic accident victims. Several ways can be carried out to address this problem. One of them is by developing several smartphone applications for accident detection and accident notification that provide aid in traffic accidents. The existing application to assist the victims merely presents the shortest route from the respondent to the victim’s location without any features that help the respondent find a route to the nearest hospital and police station. Therefore, this study develops a smartphone application for accident alerts for victims’ relatives and respondents, which assists in locating the victim’s position and the closest hospitals and police stations. This accident notification app for smartphones utilizes open-source software and is very scalable. The outcome of this study is an Android application capable of sending accident notification broadcasts, allowing the victim’s relatives and respondents to get accident notifications and drive to the accident place using the route given by the application. In addition, the developed app also provides information about the location of the nearest hospital and police station, allowing respondents nearby the location to help the victim promptly. The results of testing the application using the black box method on the Android platform indicated that 100% of the features of this application were running well. The shortest route with the Floyd-Warshall algorithm was 4.199 km, with no route deviations from the distance testing scenario. The average speed of notification delivery response from victims to respondents was 27.86 ms.

Abstract

Public Street Lighting (PSL) is essential for road safety at night. A common issue is the lack of routine inspections, leading to potential hazards. Most maintenance still relies on manual on-site visits. This study proposes an automated PSL system using Long-Range (LoRa) communication and a web-based platform to enhance efficiency and monitoring. The system enables optimized brightness control and scheduling, conserving energy and reducing environmental impact. Real-time monitoring and cloud-based data storage allow remote management via a centralized control system. Motion detection and automated lighting adjustments enhance security, while a user-friendly web interface simplifies issue identification and troubleshooting. This system is expected to improve energy efficiency, environmental sustainability, and public safety. Additionally, a placement strategy based on a predefined scheme is necessary for effective implementation.
