Effect of density control in partially observable asymmetric-exit evacuation under guidance: Strategic suggestion under time delay

作者：

Highlights：

• Dynamic guiding assistance is focused with partially observed data in density control.

• Strategic suggestion on how to set the observed regions is given under data time delays.

• Density control algorithm positively affect the pedestrians’ global distribution.

• Arching phenomena are suppressed using the partially observed data under time delays.

• Dynamic guiding assistance suppresses the trigger of collisions around exits.
