The Research of Spatial Cognition and Wayfinding in Building Complex;

So it is necessary to do some research on spatial cognition and wayfinding in underground public spaces.

Among them, "difficulties in wayfinding" have been encountered by people who travel or work or on business in big cities, and even the local residents in many cities have encountered the same problem.

Discussion of Way-finding under Natural Condition by Simulating the Procedure of Navigation;

However,DHTs are still faced with many problems,one of which is the fact that most DHTs do not take into account physical network topology in their original design,thus resulting in high routing latency and low efficiency.

, the authors makes on-the-spot investigations and researches of human road-seeking behavior experiment by a certain amount of people sepa-rately under the pilot with or without clear and definite mark.

The analysis of three experiments on site showsus the law of road-seeking tactics - "gradation" and "grouping".

For solve the problem that Petri net s route optimization search,the distribution rule of each transition implementation moment has been analyzed in the stochastic Petri net(SPN),a method for the probability distribution of transition time in arbitrary network is proposed.

The ant colony optimization is applied in route optimization of the abnormity 3D surface by method of the 3D surface discretized with grid,and the strategy of pheromone adjustment is also improved in the algorithm.
