Automated road information extraction has significant applicability in transportation. It provides a means for creating, maintaining, and updating transportation network databases that are needed for purposes ranging from traffic management to automated vehicle navigation and guidance. This paper is to review literature on the subject of road extraction and to describe a study of an optimizatio...

This task has relied upon a combination of computer simulation and experimental testing. Computer crash simulation models were developed and validated for use in the study of factors influencing injury risk of wheelchair occupants in a crash. A wheelchair transportation-specific Injury Risk Assessment method was developed and used in the comparison of injury risk associated with various wheelch...

This work develops a fuzzy linear programming (FLP) method for solving the transportation planning decision (TPD) problems with fuzzy goals, available supply and forecast demand. The proposed method attempts to minimize the total production and transportation costs and the total delivery time with reference to available supply and machine capacities at each source, as well as forecast demand an...

Ranking fuzzy numbers play a vital role in decision making problems, data analysis and socio economics systems. Ranking fuzzy numbers is a necessary step in many mathematical models. Many of the methods proposed so far are non-discriminating. This paper presents a new ranking method and using which we convert the fuzzy transportation problem to a crisp valuedtransportation problem which then ca...

Different approaches have been explored in the past to solve fuzzy transportation or shipping problems. The cost of shipping, supply, and demand quantities are all ambiguous a dilemma. Trapezoidal numbers used represent parameters this situation. can be converted into crisp using variety ranking techniques. In paper, we've studied many techniques provided comparison two them. A numerical exampl...

A novel methodology for the simulation of 2D thermohaline double diffusive processes, driven by heterogeneous temperature and concentration fields in variable-density saturated porous media, is presented. The stream function is used to describe the flow field and it is defined in terms of mass flux. The partial differential equations governing system is given by the mass conservation equation o...

Road transport safety has always been paid attention to by the production managers of enterprises. In this study, cloud model and analytic hierarchy process were applied long-tube trailer transport. The opinions 30 experts analyzed, from which 29 key parameters selected. study addressed relevance possibility automatic collection transmission obtain 12 core risk factors. macro-safety indicator s...
