Construction of dynamic trafficability map for unmanned vehicles considering multiple environmental factors and path planning.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Comprehensively considering the off-road trafficability of multiple environmental factors and carrying out optimal path planning is very important for assisting commanders to formulate battlefield maneuvering plans. Previous studies have had issues such as insufficient consideration of environmental factors that affect vehicle trafficability, failure to take into account the impact of meteorological factors on off-road trafficability, failure to consider spatiotemporal dynamic changes in influencing factors, and inaccurate construction of trafficability maps. Therefore, this article constructs a dynamic trafficability map of unmanned vehicles that integrates multiple environmental factors, considers the impact of meteorological factors on vehicle trafficability, takes into account the spatiotemporal dynamic changes of vehicle influencing factors, and conducts research on unmanned vehicle path planning based on the constructed trafficability map and improved A* algorithm. The results indicate that the constructed vehicle dynamic trafficability map can reflect the trafficability of different vehicles at different times. The paths planned by the traditional A* algorithm and the improved A* algorithm are different, and the improved A* algorithm is superior to the paths planned by the traditional A* algorithm. The relevant research provides theoretical and technical guidance for evaluating the trafficability of different vehicles at different times within a region.
