Description

Technical Field

[0001] The present application relates to the field of traffic planning and design, and in particular to a method and device for planning the spatial layout in front of a school gate based on picking up and dropping off students by motorcycle or electric vehicles. Background Art

[0002] In recent years, traffic congestion and safety hazards caused by picking up and dropping off students have become increasingly prominent. Therefore, it is necessary to plan the layout of the space inside and outside the school to alleviate the traffic congestion problem when picking up and dropping off students.

[0003] There are many methods for solving the traffic congestion problem when picking up and dropping off students in the prior art. The first is to combine the intelligent scheduling scheme for picking up and dropping off students with student cards, school gate gates and school information platforms, which can reduce waiting time by speeding up the efficiency of students entering and exiting gates and the efficiency of parent-student interaction in picking up and dropping off students, thereby indirectly alleviating the traffic congestion problem of picking up and dropping off students. This method does not involve the spatial layout planning in front of the school gate, and it is difficult to ensure the order of parents picking up and dropping off students, and it is easy to lose sight of one thing and it is difficult to improve efficiency; the second is to use the underground parking space in the school to move the motor vehicle pick-up and drop-off mode to the underground to alleviate the ground pick-up and drop-off traffic congestion problem in front of the school gate. This method can separate the impact of motor vehicles, but there is a prerequisite for the implementation that the school must have sufficient underground parking space, and it cannot be widely used; the third is to carry out spatial layout planning for picking up and dropping off students based on the impact of cars used for picking up and dropping off students in front of the school gate, such as CN118133405A, which focuses on the impact of cars on picking up and dropping off students, and pays less attention to or even does not involve other types of vehicles. However, in some primary and secondary schools in some cities, low-cost, convenient and fast motorcycles and electric vehicles have a greater impact on school pick-up and drop-off than cars, but the existing technology has not studied this. Therefore, how to reasonably plan the spatial layout of picking up and dropping off students in front of the school gate under the influence of motorcycles and electric vehicles is an issue that needs to be urgently solved by existing technology.
