“…The hooter will be louder as the level crossing nears, and finally it will be silent after the train passes by. There are several other methods proposed for automatically controlled railway gate at the level crossing, railway track switching mechanism and the movement of the train using sensors, micro controllers for reduction of railway accidents but all demand heavy investment [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Safety on the Indian Railways network is the end product of the cohesive fusion of its myriad parts . Railroad related accidents are more serious or deadly than other transportation accidents in terms of severity and death rate etc. The problem of railway accidents is not of safety standards but the execution of standards. Unmanned Level Crossings continue to be a matter of concern for Indian Railways as most of the train mishaps take place in these unmanned level crossings, . There are about 10,000 unmanned railway crossings in the country which account for around 40 per cent of accidents involving the railways. Therefore, Safety at unmanned level crossings is a cause of serious concern for railways and the public transporter is exploring various ways to address the issue. This paper presents a novel concept of an application to improve safety at unmanned level crossings without the burden of a huge infrastructure cost to the railways governing body. A low cost innovative reliable model has been proposed for automatic blockading of unmanned railway level crossings. . It explores too the quest for improved performance, and the need to focus not just on safety, but to contribute to the delivery of a cost-effective, efficient railway as well.

“…In this study, the LAN network was experimentally applied as a communication network among level crossings, but high safety and reliability of the communication network are required in actual rail. The new signaling system where the normal internet protocol is used to control signal devices [4,5] will solve this problem. Furthermore, application of wireless sensor network technology to railway signaling system [9] will be useful for the network.…”

“…Recently, many systems using ICT (Information Communication Technology) have been developed. For instance, the railway signal system which controls devices by using the internet protocol to transmit the signal command not via a metal cable but via an optical Ethernet cable was developed and installed [4,5]. Moreover, train control systems using radios have been realized [6,7] and a system, named "ATACS" operates commercially in Japan [8].…”

A level crossing which is a cross point between an automobile road and a railroad is unavoidable for a railway operator. Of course, the safety at a level crossing is top priority and, at the same time, we have to consider the convenience and availability for passers by (pedestrians, vehicles, etc.).Basically, a current level crossing controller is a standalone device. Once it detects a fault, such as lightning stroke damage to a train sensor, it makes/keeps warning according to the fail-safe philosophy and stops passers by entering the train area.However, this long time warning causes not only inconvenience for the passer by but also dangerous situations. For example, it may interrupt emergency vehicles, or it may cause situations where a frustrated passer by would run through the level crossing barriers and enter the train area.Recent ICT (information communication technology) progress has been applied to solve our issues. We have developed a network level crossing system. More than three level crossing controllers are connected through the Ethernet LAN connection to exchange their operational data. At normal state, they are operating as stand-alone machines, once one controller detects a problem, it operates not by means of its own data but by another controller's data. As a result, by a degraded level crossing function, passers by need not undergo unnecessary extensive warning.We have produced the network level crossing system experimentally and examined it in house. Numerical estimation using actual train operation data shows that in cases of malfunction of a train detector, the current level crossing system warns every time, whereas our system warns only 18.7% of the time. It means that the current system completely blocks passers by and our system provides many chances to pass the level crossing. Our system achieves the convenience and

“…Since current signal devices have to operate independently, they sometimes have same logics inside. Then, we shift all signal logics hard-wired to software by unifying of system architecture shown in Fig.9 and applying of autonomous decentralized architecture to the software [4]. And then, to eliminate physical interface between functions, we integrate various logic controllers into one logic controller.…”

When replace railway interlocking devices, setting up of large number of signal cables and confirming of wiring connections are required. So, it is worried that serious transport disorder caused by human error in wiring works would occur. We have developed a railway signal control system utilized optical LAN to reduce the signal cables and wiring works. Moreover, all signal devices operate independently, designers have to handle all devices one by one and pay great attention to avoid causing harmful influence each other. We propose the data-driven method to make easy to replace interlocking device. This logic is rearranged according to the field device in order to simplify and decrease design duties of designers. In this paper, we introduce this system, and describe network transmission, safety-related communication and software configuration of the system.
