Abstract: The article presents a model of an unguarded railway crossing equipped with an additional driver warning system. Public WSN, Wi-Fi, and WiMax standards have been proposed for transmitting information to road users about an approaching train. The paper demonstrates how wireless data transmission based on public networks can significantly increase the safety level of future railway traffic control systems.1. CURRENT STATE OF SAFETY
AT RAILWAY CROSSINGS
One of the most important and at the same time most difficult tasks in railway traffic is ensuring safety at railway crossings. The number of railway accidents is obviously related to the volume of transport, the intensity of rail and road traffic, and the efficiency of the information transmission system.
In the long-term operation of railway crossing signaling systems (ssp), it is possible for a system failure to occur; therefore, in such a situation, the goal is to ensure that only a system failure occurs, not a safety failure.
In the European Union, at least 600 people die every year in accidents at railway crossings. 95% of these accidents are caused by road users, and in Poland, as many as 98% [4].
The state of traffic safety on railway lines in recent years is illustrated in Table 1 below. From the perspective of railway safety, special attention has been paid to railway accidents in the group at railway crossings – collisions with road vehicles. (…)
