Temporary Design on Public Open Space for Improving the Pedestrian’s Perception Using Social Media Images in Winter Cities

Due to the severe climate, residents of winter cities tend not to utilize public open spaces inwinter. Temporary design interventions such as emblematic events are always proposed in wintercities to enhance pedestrian activity by celebrating the season and improving the perception ofwinter. In this study, we clarify the impact of the event on pedestrians’ perception to determinethe role of temporary design in improving the perception of public open spaces in winter cities.Using the example of event known as “Ice Town” on the Lenin Square in Khabarovsk, the contentof the Instagram images was analyzed to determine their perception during and after the event.The analysis includes classification of the images into clusters related to dierent urban elementsusing transfer learning with CNN (convolutional neural network). A total of 10,200 generated imageson the Lenin Square were considered, with 1700 images which relate the event itself. This accountsfor approximately 20% of all data, while those which related to the during the permanent use of LeninSquare accounted for just 6%. Temporary design of public open spaces has great potential to involvepedestrians in interacting with urban and natural environments in winter cities, even in severe coldclimate, by improving an impression of a place.
