Railroad traffic light sensors to anticipate jams at junctions based on ATMega8

Traffic congestion is a problem that has long occurred in Indonesia, especially in big cities. Traffic congestion that occurs can cause various losses, one of which is time loss because it can only run at a very low speed. Then it will create a waste of energy, because going at low speed will require more fuel. Congestion is also able to increase the saturation of other road users, not only that traffic jams also have a bad impact on nature which causes air pollution. And there are many more impacts of traffic jams that can make traveling very uncomfortable. One of the locations of traffic jams often occurs on roads located around railroad crossings. Therefore, In this study, it is proposed to make a traffic light sensor adjacent to the train track to anticipate long traffic jams based on atmega8 and infrared sensors, with the stages of collecting data, recording transportation activities at the location of the jam, then designing a sensor device. The system built is to read the volume of vehicles on the road and prioritize the road with the highest volume of vehicles to get the green traffic light condition. Based on the results of the manufacture of infrared sensors and atmega8 can be tested to reduce the level of congestion at crossroads adjacent to the railroad.

Implementasi Lampu Peringatan Pada Perlintasan Tanpa Palang Pintu Kereta Api Berbasis Mikrokontroler

This research aims to make a warning light with a microcontroller base as a control system. With the aim of reducing the use of manual systems in general that are in use today. The advantage of this warning light control system is that it functions to reduce the number of accidents that occur and can be used for railroad crossings where there are still no latches that have not been installed on the railroad railroad crossing (wild road). The display of the work system that is made will be monitored using a web monitoring display that supports and is easy to understand. Even though it has some delay in the process, the planned system has run well based on the average delay value. The experimental results show the average delay measured in the system is 0.31 seconds before sending from the node and 0.49 seconds when there is a change in conditions, while when there is data transmission from the node. The measured packet loss on the system is 0% before transmission and fans and 8.88% when data is transmitted from the node.

Level Crossing Barrier Machine Faults and Anomaly Detection with the Use of Motor Current Waveform Analysis

Barrier machines are a key component of automatic level crossing systems ensuring safety on railroad crossings. Their failure results not only in delayed railway transportation, but also puts human life at risk. To prevent faults in this critical safety element of automatic level crossing systems, it is recommended that fault and anomaly detection algorithms be implemented. Both algorithms are important in terms of safety (information on whether a barrier boom has been lifted/lowered as required) and predictive maintenance (information about the condition of the mechanical components). Here, the authors propose fault models for barrier machine fault and anomaly detection procedures based on current waveform observation. Several algorithms were applied and then assessed such as self-organising maps (SOM), autoencoder artificial neural network, local outlier factor (LOF) and isolation forest. The advantage of the proposed solution is there is no change of hardware, which is already homologated, and the use of the existing sensors (in a current measurement module). The methods under evaluation demonstrated acceptable rates of detection accuracy of the simulated faults, thereby enabling a practical application at the test stage.

Modeling of Automatic Door at Railroad Crossing Without Guard Based on Internet of Things in Indonesia

Railroad crossings without doors and guarding are the cause of accidents between vehicles with trains other than human factors, and in Java, Indonesia has 6,000 level crossings. The solution that can be done is to install a door, but if a door is installed, a guard is needed to operate the door, this will cause new problems, namely employment. So the right solution is to design an automatic door, this study aims to create a sensor-based automatic door model and Internet of Things (IoT). The design of a miniature model of automatic railroad doorstop using SG90 9g micro servo with TCRT-5000 sensor based on Arduino Uno ATmega 328 microcontroller. The sensor is used to detect the position of the train, in miniatures that have been made using 2 TCRT-5000 sensors. The function of each sensor is to detect the arrival of the train, activate the speed and detection system that the train has passed through the doorstop. Miniature door bars are driven by 9g SG90 micro servo. Computer monitors in miniatures can function properly, which is capable of displaying train speed and waiting time for train arrival. The results of the miniature performance test for all supporting components can function optimally, namely the TCRT-5000 sensor can function and be accurate in detecting the position of the train and servo that move according to the miniature system program.

Palang Pintu Kereta Api Pneumatik Otomatis Berbasis PLC Omron CP1E-NA20DR-A

One alternative in reducing accidents at railroad crossings without guards is automatic pneumatic railroad crossings. This tool uses PLC (Programmable Logic Controller) as a processing system. Automatic crossing railroad crossing works by using two proximity sensors that are placed on the right and left crossings with a distance far from the crossing (approximately 1 KM). The system outputs are pneumatically actuated sirens, lights and door lintels. At most this door will move up and down closing and opening the crossing. The use of pneumatics in manufacturing because pneumatics saves more space around the crossing and is safe. In testing, detection is done in 2 opposite directions. The results show the tool has been working to close and open crossings with good performance.Salah satu alternatif dalam mengurangi kecelakaan di pintu perlintasan kereta api tanpa penjaga adalah palang pintu kereta api pneumatik otomatis.

Rails-Next-to-Trails: A Methodology for Selecting Appropriate Safety Treatments at Complex Multimodal Intersections

There are more than 212,000 at-grade railroad crossings in the United States. Several feature paths running adjacent to the railroad tracks, and crossing a highway; they serve urban areas, recreational activities, light rail station access, and a variety of other purposes. Some of these crossings see a disproportionate number of violations and conflicts between rail, vehicles, and pedestrians and bikes. This research focuses on developing a methodology for appropriately addressing the question of treatments in these complex, multimodal intersections. The methodology is designed to be able to balance a predetermined, prescriptive approach with the professional judgment of the agency carrying out the investigation. Using knowledge and data from the literature, field studies, and video observations, a framework for selecting treatments based on primary issues at a given location is developed. Using such a framework allows the agency to streamline their crossing improvement efforts; to easily communicate and inform the public of the decisions made and their reasons for doing so; to secure stakeholder buy-in prior to starting a project or investigation; to make sure that approach and selected treatments are more standardized; and to ensure transparency in the organization to make at-grade crossings safer for pedestrians and bicyclists, without negatively impacting trains or vehicles.
