Quantitative and qualitative monitoring and evaluation of risk management programs will play an important role in the development of Tehran metropolitan railway transport. Considering the tectonic studies, seismic zones, land degradation and faults in north and south of Tehran, the development of underground railway lines, the assessment of the vulnerability of subway stations and the escalation of the crisis with the destruction of urban exhausted earthquakes is very important with the occurrence of earthquake and flood. This study, focusing on the issue of risk assessment and vulnerability of the development of the rail transport network and the approach to physical and aerospace hazard monitoring of metro stations. For this purpose, three selected metro stations in Tehran were studied. In the research, a combined method based on library studies, review of records and records, Delphi technique, AHP method, and overlaying of layers have been used. The results of the vulnerability assessment indicate that each of Tajirish, Nawab and Darvazeh Shemiran, with a risk number of 5.10, 5.76, and 5.79, are in the risk limit range, respectively. In fact, all stations need to adopt smart measures and management and executive solutions to reduce potential damage.

This study focused on the public transport risk assessment in District one of Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an effort to help urban managers to assess the risks in the public transport and prevent road accidents. Finally, the risk identification and assessment of public transport in District one yielded several results to answer the research questions. The hypotheses analysis suggested that safety issues involved in public transport are concerned by urban managers. The key reactive measures are investigation of accidents, identification of causes and correction of black spots. In addition to high costs, however, the reactive measures give rise to multiple operational problems such as traffic navigation and guaranteeing user safety in every operation. The case study highlighted the same fact. The macro-level management in the metropolis of Tehran is critical. The urban road casualties and losses can be curtailed by preventive measures such as continuous assessment of road safety.
