The safety of railway level crossings is one of the critical concerns in the railway industry, given the potential risks for accidents involving trains and road vehicles. A comprehensive understanding of the various safety measures in place at these crossings is essential for assessing their effectiveness and for planning improvements. Various methodologies have been developed to address these risks, each with its own safety measures and considerations. This article explores the classification of these methodologies, focusing on each approach’s key components and objectives.

One of the main quantitative parameters used to describe the safety status of the level crossing is the Danger Index. The basic methodology for calculating the Danger Index is explained in the “Safer-LC project.” Also, the UIC Safety Platform Guidance “Best practice for level crossing risk assessment” addresses additional assessment criteria for level crossings.

The Danger Index is a quantitative measure that assesses the level of risk at the intersection of railway and road. It considers several factors, such as:

• the frequency of trains;
• the maximum speed of trains;
• traffic volumes on the road and railway line;
• visibility conditions;
• presence of warning systems for road users and train drivers.

By calculating the Danger Index, transportation authorities can identify high-risk intersections and implement appropriate safety measures to prevent accidents. These may include improved warning systems, enhanced signage, better road markings, and upgraded level crossing infrastructure.

Assessing the Danger Index also helps raise safety awareness among drivers, pedestrians, and train operators. Public education campaigns and targeted safety initiatives can be developed to promote safe practices at railway-road intersections.

The Danger Index calculation is not a one-time process. Regular monitoring and evaluation are necessary to identify changes in risk factors and adapt safety measures accordingly. This ensures that intersections remain safe as traffic patterns and conditions evolve.
