Simulation and Application of Urban Road Landscape Based on Geographic Information Data.

In this paper, we study and analyze the urban road landscape by integrating big data with GIS and designing a simulation system. Underwood is selected as the base model and calibrated for optimal density and capacity. The traffic flow model is optimized, and the minimum flow rate of each class of road is corrected; the traffic volume of highway and expressway in the early morning and at night is adjusted to make up for the discrepancy between the calculated flow rate of the model and the actual situation due to the unstable speed. Investigate and analyze the pollutants produced by enterprises along the road and select suitable and targeted plants to enhance the ecological protection of road landscape and optimize and improve the park environment; combine the regional culture and apply the ceramic culture to the design of road landscape vignettes; select suitable water and moisture-resistant plants for slope protection plant landscape design, to form a trinity of ecological protection, landscape road, and riverfront green space of industrial park road landscape. As a new basic geospatial infrastructure and carrier, 3D city has a unique spatiotemporal view to plan and manage the operation and maintenance information of the whole city. This part of the study takes urban planning, community management, urban publicity, and tourism management as demonstration cases and focuses on the elaboration and verification of how 3D city data and 3D urban geographic information are applied in the refined urban construction and management. Typical road measurement data are selected, and the applicability of the road traffic flow model of each level is judged by numerical analysis. An interactive road model editing method with the help of auxiliary information is proposed. With the help of auxiliary information displayed in different ways, the operation of adjusting road height in three-dimensional space is transformed into operation in a two-dimensional plane, which can effectively simplify the operation process and improve the accuracy of model editing.
