Analysis of Mechanism and Differences of Tourists Congestion Perception

To reasonably obtain the congestion perception of tourists, a perception mechanism of visual assessment method, immersive method, and tourist self-registration method was explored, and the differences of three survey methods were discussed in terms of perceived objects and perception. The stated preference survey was designed and carried out to quantitatively analyze the impact of factors such as recall time and density on tourists congestion perception acquired by the three survey methods. A tourists congestion perception model was established and the partial effects of the parameters were analyzed. Results show that the variables including tourist density, distribution characteristic, and recall time, have a significant impact on tourists congestion perception degree. For each increase of 1.00 person/m² of tourist density, the probability of tourists congestion perception degree (Y=2) under the three methods is reduced by 3.06%, 9.26% and 10.23%, respectively, which indicates that tourists congestion perception degree under self-registration method is the most sensitive, while the tourists congestion perception degree (Y=4-5) is the most sensitive under the immersive method.
