TECHNICAL FIELD
[0001] The present application relates to the technical field of intelligent transportation planning, and particularly relates to a traffic demand prediction method for a new gas station project. BACKGROUND
[0002] As an important part of urban transportation infrastructure, the planning layout and traffic organization of urban gas stations directly affect the efficiency and safety of regional traffic operation. With the acceleration of urbanization and the continuous growth of motor vehicle ownership, gas stations as key nodes for vehicle energy supply have a significant impact on the traffic capacity, traffic order and traffic safety of the surrounding road network. If not properly planned, gas stations may become a cause of traffic congestion and even cause traffic accidents, reducing the overall service level of the urban transportation system. During the site selection and detailed planning of a gas station construction project, conducting a scientific and systematic traffic impact assessment is essential to ensure its coordinated development with the urban transportation system. According to the Technical Standards for Traffic Impact Assessment of Construction Projects, traffic demand prediction is one of the core contents of traffic impact assessment, which quantitatively analyzes the impact of the newly added traffic volume on the surrounding road network after the project is completed, providing data support for planning decisions. However, in the existing technology, traffic demand prediction for gas stations relies heavily on traditional models and does not fully consider the differences in road network structure, land use, parking spaces, and traffic flow around the gas station, resulting in a large deviation between the predicted traffic demand and the actual situation. This deviation directly affects the reliability of the TIA conclusion, which in turn misleads the planning decision, making the gas station itself or the surrounding road network a new traffic bottleneck or safety hazard source. Therefore, there is an urgent need for a traffic demand prediction method for new gas station projects to address the technical problem of accurately predicting traffic demand for new gas station projects.
