This diploma thesis elaborates on dangers of intentional misuse of transported hazardous substances. Introduction part is about legislation which determines conditions for hazardous substances treatment and their transportation. There are several types of transportation, they are described in separated chapter. Road transportation dominates in Czech Republic. Focus is put on motivation factors for misuse of hazardous substances. Factors increasing risk of misuse of hazardous substances follow. Based on it, suggestions for precautions and means to lower the risk were created. Separated chapter is dedicated to methodology for determining attractiveness of hazardous substances. To map situation in Czech Republic, I did survey in several companies. Results are summarized in last chapter.

Industry both consumes and creates an abundance of dangerous goods, which must be transported from producers to end-users. This creates opportunities for incidents, including traffic accidents, which could release poisonous, corrosive, flammable or carcinogenic substances into the environment. Releases of dangerous goods at a location may pose a significant threat to the health of the neighbouring population. The Durban South Basin, with its hazardous mix of heavy industrial, employment and residential areas, was chosen as the case study for research into the risks associated with the transportation of dangerous goods. High levels of traffic flow occur in this region and significant volumes of dangerous goods are transported on the roads within the basin. The objectives of this investigation were to: develop a methodology that may be applied to estimate the likelihood and consequences of releases of dangerous goods due to road accidents; and to evaluate the usefulness of this methodology by applying it to estimate the risks posed to the people residing in, working in and travelling through the Durban South Basin. The literature pertaining to risk assessment of dangerous goods transport was examined. A review was undertaken of the current state of the art and the theory and methodology used by previous researchers. As intersections provide greater opportunities for vehicles to be involved in accidents, traffic surveys were conducted at selected intersections within the Durban South Basin in order to obtain an indication of the flow of dangerous goods vehicles and the types of dangerous goods being transported through these locations. Two approaches were utilised to estimate the likelihood of dangerous goods accidents and releases at intersections: a deterministic model and an innovative method based on Monte Carlo simulation. Dispersion modelling and geographic information systems were integrated to estimate the impacts of accidental releases of dangerous goods at intersections. Queuing analysis was combined with dispersion modelling to estimate the risks posed to road users from dangerous goods releases. The investigation verified that dangerous goods transportation risk assessment could be performed even when there are substantial data uncertainties. Furthermore, in comparison to the deterministic approach typically used in transportation studies, Monte Carlo simulation facilitates a deeper understanding of the nature and distribution of dangerous goods accident risk. The results suggest that although dangerous goods accidents and releases are infrequent, the potential exists for very serious incidents involving large numbers of injuries. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, 2005.

A project report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Engineering. Johannesburg, 1992. / The formulation of effective safety measures to counteract the potential for disaster presented by the transportation of hazardous materials requires that reliable data is available as to the nature and extent of such traffic. Such data is currently unavailable and a roadside interview survey was conducted in the PWV area in order to ascertain the quantities and type of material being transported locally. the routes used, the types of vehicles and containers involved, and compliance with existing regulations. It was found that of the 1068 Vehicles surveyed carrying hazardous material, only 22% fully complied with existing legislation. A risk assessment model for use by both operators and authorities is then developed, in which the survey data is input to determine the least risk route between Johannesburg and Sasolburg. / AC2017

The Pennsylvania Department of Transportation is conducting a study focusing on risk assessment associated with movement of hazardous materials, and determination of corresponding vulnerable areas in the state. A goal of this research is to make the hazardous material risk assessment an integral part of accident analysis find risk management functions in transportation agencies. To achieve these objectives, the authors developed an interactive, user friendly microcomputer package. The risk assessment model behind this package relies on the notion that data can be obtained easily and updated over time. This package, therefore, employs existing data on accident reports, traffic information, and geometric parameters that is transferred from a mainframe database to the microcomputer. The modelling framework consists of several modules: LEVEL, EDIT, INFO, ZOOM, ANALYZE, MITIGATE, PRINT, HELP, RESET, and QUIT Module. It employs a color coding of streets, municipalities, counties, and states for easy and clear interpretation. To enhance graphic display capabilities of the model, shape points are digitized for each network link. In the LEVEL module three different scales are defined ranging from a small scale county level to a large scale street level, namely, 1)County, 2)Municipality, and 3)Street Any scale may be selected for analysis at any time in the procedure. All other modules are, then, performed on the basis of chosen scale. The EDIT module can be used for data input or investigating hypothetical changes in order to determine the best strategies for problem alleviation. Creating or deleting techniques are included to avoid redigitizing the whole map provided link geometries will be changed over time. Edited data can either be saved on diskette files or be used temporarily in memory without altering original flies. The INFO module employs dialogue boxes with bar graphs or color shadow maps to facilitate depicting numeric values of input and output statistics. The ZOOM module allows user to see the area in question in more detail. The ANALYZE module comprises the main part of this package. Two primary features include : 1) vulnerability and risk assessment at the macro level which provides a ranking of the most affected counties, municipalities and streets (Macro analysis), and 2) risk analysis at the micro level (i.e. street level) which determines corridors of least risk between fixed origins and destinations (Micro analysis). The MITIGATION module is provided for evaluation of mitigating measures. The HELP module uses pop-window techniques to provide quick information with minimal program disruption. The RESET module exits ZOOM module and resets screen. Finally, QUIT module shells out to DOS or exits the package. / Ph. D.
