Application Research On The 3D Map In Urban Rail Transit APP

With the rapid development of the national economy,the scale of urban construction continues to expand,and urban rail transit as a new mode of transport is also developing rapidly,which plays an unmatched important role in urban public transport.With the increasing development of rail transit and the gradual maturity of Internet technology,mobile rail transit service products have become an inevitable trend.At present,China's various cities having been equipped with urban rail transit conditions,the development and use coverage of rail transportation APP product is also limited to several more developed cities,such as Beijing,Shanghai,Guangzhou,and Shenzhen.In these cities' track traffic APP of R&D use,due to the short time of development of such products,the analysis of user needs being not sufficient and other reasons,result in that a large number of applications cannot fully meet the needs of the majority of users,so it cannot maximize the application of its product value,resulting in a waste of resources.Three-dimensional map,as a most intuitive,most three-dimensional map representation form,has a very high practical value.The three-dimensional map can be applied to the urban rail transit APP,through the form of three-dimensional map to show the marked location of the rail transit site structure,location,and public facilities.It can greatly improve the site's directivity and orientation,so that users can gain more intuitive and more convenient operation experience in the use of this product,which also promotes the efficiency of people's travel and solves many problems.At the same time,perfect it in the APP function,so that its value can be maximized.This subject is based on the Chengdu Metro Line 2 Tianfu Square Station,taking the station structure and the layout of public facilities as the design prototype,to draw a complete three-dimensional map model.Then through the product users' needs,product positioning analysis builds product framework,combined with the three-dimensional map of graphic icon design,interface design and drawing,ultimately designing a APP product that is suitable for users' habits,functional,and easy to operate.So achieve the public service,and promote the purpose of solving users' travel problem.This paper sunmmarizes the status quo of the development of urban rail transit APP,combined with product comparison analysis and user demand analysis.In the grasp of UI design principles in the case,it conducted more perfect design practice,starting from the APP product functionality and operability,joining and improving the function with more practical value.It enhances the software's orientation and timeliness while optimizing the ease of operation of the product,minimizing the operational flow and allowing users to enjoy a more comprehensive and easy operation experience in the same operating interface.So it maximizes the role of rail transit APP more smoothly,efficiently and succinctly,thus finally realizing the user experience optimization of the track traffic APP.
