A serious incident involving dangerous goods in a tunnel can be extremely costly in terms of loss of human lives, environmental degradation, tunnel damage and transport disruption. On the other hand, needlessly banning dangerous goods from tunnels may create unjustified economic costs. Moreover, such a ban might force operators to use more dangerous routes, such as densely populated areas, and thus increase the overall risk. This report proposes regulations and procedures to increase the safety and efficiency of transporting dangerous goods through road tunnels. It introduces two models, devel

Logistics has become a strategic factor for development and competition. Terrorist attacks, such as 11th of September 2001 in the USA, have caused the introduction of rules and procedures, which affect the overall logistics showing the vulnerability of the global economy. This book presents the status of research on dangerous goods transport.

A quantitative risk analysis (QRA) regarding dangerous goods vehicles (DGVs) running through road tunnels was set up. Peak hourly traffic volumes (VHP), percentage of heavy goods vehicles (HGVs), and failure of the emergency ventilation system were investigated in order to assess their impact on the risk level. The risk associated with an alternative route running completely in the open air and passing through a highly populated urban area was also evaluated. The results in terms of social risk, as F/N curves, show an increased risk level with an increase the VHP, the percentage of HGVs, and a failure of the emergency ventilation system. The risk curves of the tunnel investigated were found to lie both above and below those of the alternative route running in the open air depending on the type of dangerous goods transported. In particular, risk was found to be greater in the tunnel for two fire scenarios (no explosion). In contrast, the risk level for the exposed population was found to be greater for the alternative route in three possible accident scenarios associated with explosions and toxic releases. Therefore, one should be wary before stating that for the transport of dangerous products an itinerary running completely in the open air might be used if the latter passes through a populated area. The QRA may help decisionmakers both to implement additional safety measures and to understand whether to allow, forbid, or limit circulation of DGVs.

Dangerous goods are substances with hazardous properties and products that can harm people, the environment or property. Incorrect transport or storage of such cargo can lead to human or animal disease, poisoning, burns, as well as explosion, fire, damage to other cargo, rolling stock, structures and equipment, contamination of the environment and water. It is not possible to avoid the risk of transporting dangerous goods, but it can be controlled and minimized.A study on the possibilities for improving the transport of dangerous goods in the European Union countries was carried out. The study was conducted using a survey method. Questionnaires were sent to transport companies carrying dangerous goods. These companies are based in the European Union countries. The purpose of the study was to find out what security measures the relevant transport company is taking to ensure the safe transport of dangerous goods, the modes of transport of the most dangerous goods, the countries where the dangerous goods transported by the respective carrier are mostly transported, the information means used by the company for fast and safe transportation to the consignee of this type of cargo.The article presents the results of the study on the transport of dangerous goods in the EU countries. The questionnaire analysis showshow respondents in the European Union countries evaluate the transport of dangerous goods, what dangerous goods are usually transported, what are the causes of accidents and what is being done to reduce the risks of transporting dangerous goods.After analysis of the results of the study it can be stated that the EU countries have a variety of security measures to reduce the risk of dangerous goods transport. Therefore, Lithuanian carriers can be offered various means of safe transportation of these goods.The article provides guidance measures to ensure the safe transport of that cargo.
