Abstract:

To solve the problem of vehicle cross-country passage planning, the main influencing factors on cross-country passage have been analyzed. It proposed a data model which using hexagonal grid to do terrain quantization, researched on the spatial data structure and the modeling process of attribute information of hexagonal grid. The factors of influencing vehicle cross-country passage have been got on classification analysis, focus on the influence of terrain, roads, slope, et al. For vehicular traffic cross-country passage levels, it proposed a comprehensive multi-factor analysis method. Finally, the cross-country passage analysis model under the combined effects of multiple factors has been established.

Key words: hexagonal grid, hexagonal grid terrain quantization, cross-country passage analysis, multiple-factor, general rules
