Aiding Route Decision for Hazardous Material Transportation
This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...
متن کاملPath Planning of Road Hazardous Material Transportation based on TransCAD
A risk assessment model is constructed for the hazardous materials (hazmat) road transportation combining features of TransCAD traffic forecasts, and based on traffic planning network of spatial analysis and attribute process, the database for path planning of hazmat transportation was set up. Based on the TransCAD platform, this research analyzes the risk value of hazmat transportation in each...
متن کاملGeneralized route planning model for hazardous material transportation with VaR and equity considerations
Recently, the Value-at-Risk (VaR) framework was introduced for the routing problem of a single hazmat trip. In this paper, we extend the VaR framework in two important ways. First, we show how to apply the VaR concept to a more realistic multi-trip multi-hazmat type framework, which determines routes that minimize the global VaR value while satisfying equity constraints. Second, we show how to ...
متن کاملApplication of Chaos Theory in Hazardous Material Transportation
Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...
متن کاملAccessibility Indicators for Transportation Planning Using GIS
In this paper a method to create GIS-based accessibility indicators is presented. The method allows to create person-by-person and store-by-store (disaggregate) accessibility indicators but also to derive zonal summary (aggregate) indicators that can be used in more traditional transportation planning applications. These indicators have also been used as explanatory variables in person-based tr...
