In this paper, a history-based parametric method was proposed and implemented. However, the size of each translator that exchanges the feature and parametric information tends to be large, due to the implementation of duplicated functions. Furthermore, because a history-based parametric translator uses a procedural model as a neutral format, it requires a geometric modelling kernel to generate ...

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...

Background & Aims of the Study:  Collection and transportation of municipal solid waste (MSW) for various reasons, especially economic and social are considered as one of the most important elements of the solid waste management system. More than sixty percent of the costs in solid waste management systems in different countries are due to the collection and transportation...

Evaluating safety impacts of network planning alternatives have a potential to improve safety in a proactive manner at the system level and at a minor cost of additional analysis. This paper presents a computer-implemented GIS-based method of predicting safety for planning alternatives. Although applicable to large road networks, the method predicts crashes at the road facility level (intersect...

In this study, we aimed to assess the solution quality for location-allocation problems from facilities generated by the software TransCAD®, a Geographic Information System for Transportation (GIS-T). Such facilities were obtained after using two routines together: Facility Location and Transportation Problem, when compared with optimal solutions from exact mathematical models, based on Mixed I...
