Study On The Optimization Method Of Driving Ground Cleaning Vehicle Shape Under Integrated Transportation Hub

The market for and application scenarios for ground cleaning vehicles are growing as the pace of mechanization of urban sanitation operations increases.A well-designed ground cleaning vehicle may suit the aesthetic demands of visitors,increase satisfaction,and promote a positive impression of the city.A comprehensive transportation hub is a window that displays the city’s image.It would be interesting to investigate how to construct a ground cleaning vehicle that satisfies perceptual imagery requirements in a large-scale transportation hub context.This project combines eye-tracking technology and interactive genetic algorithm to extract design elements effectively,and proposes a system design method with certain improvement and optimization based on the modeling characteristics of ground cleaning vehicles in specific scenes.This paper organizes the functional and aesthetic design requirements for the ground cleaning vehicle in this environment,using the Shanghai Hongqiao transportation hub as an example.It also collects traveler perception data for the driving floor scrubber and displays sample driving floor scrubber images.The gray correlation method was used to confirm the imagery vocabulary with the greatest influence on styling satisfaction;the eye-tracking technology was introduced to extract the key design parts under the imagery of user requirements;the quantitative I theory was used to establish the relationship between perceptual imagery and styling forms,so as to build a styling library.Finally,through the interactive genetic algorithm,the population common scoring model is used to transform the user evaluation into the fitness value,and the genetic operation is performed on the population to finally obtain the driving scrubber appearance shape that satisfies the passengers.This project applied the above method to design and practice the ground cleaning vehicle of comprehensive transportation hub,and verified the feasibility of the method through perceptual evaluation,which has certain reference significance and value for the ground cleaning vehicle styling design in China.
