Rail transport is a reliable and safe mode of transportation. However, level-crossing accidents are still a significant challenge for the industry to overcome. To reduce intersection risk, railways worldwide must consider network conditions, the type of control system in place, and the number of intersections. The type of infrastructure system used is a crucial factor in rail transportation, especially in intersections of rail and road, such as underpasses, overpasses, and level intersections. In Iran, the IP risk index is used to prioritize level crossings.
This study aims to investigate the various methods used in different countries, analyze the existing conditions of same-level intersections by examining data from Iranian railways, and identify the main causes of accidents that have occurred in these intersections in the past decade. One of the main challenges is to identify the most effective solutions to reduce risks at level crossings while working within limited resources.
The ALCAM method from Australia was used to determine the amount of risk in level intersections in Iran, based on each region. Since the ALCAM model, in complement to considering the physical characteristics of the crossing, consider the exposure factor and the consequence factor for prioritizing the crossings, as a result, the method used in this research estimates the risk number and prioritizes the intersections more accurately. The study identified one high-risk intersection located in Khorasan (Shaheed Motahari-Fariman) and five high-risk intersections in the Tehran region. These intersections are Pishva-Varamin, Bahram-Varamin, Ray-Bahram, Tepe Sefid-Tehran, and Varamin-Pishva. These are the most dangerous level crossings in Iran, ranked by risk number using the ALCAM method.
Finally, the study provides solutions to reduce the risks in high-risk areas based on the identified main causes of accidents.
