The use and parking of the shared bicycle have the remarkable characteristics of time concentration and space concentration, but the fixed parking facilities do not have the characteristics, so that the mismatch of time and space parking supplies and demands is caused, and the parking contradiction is generated. Specifically, the contradiction of parking is mainly manifested by unbalanced supply and demand and morning and evening peak tide problems. Particularly, in rail transit stations and large commercial office facility nodes, the shared single-vehicle parking requirements of the nodes have obvious time difference in different time periods, and compared with other road sections, the shared single-vehicle parking requirements have obvious space difference. Taking the early peak as an example, the rail transit station will attract a large amount of shared bicycles to park, the parking area supply of the conventional setting can not satisfy the parking demand, and the shared bicycles nearby the commuting residential quarter largely gush to the rail transit station, often causing the phenomenon that the parking spot has no available vehicles.
The problem of contradiction between parking supply and demand is solved by two ideas, namely, in-situ excavation is carried out, the supply scale of parking facilities for parking high demand points is improved, but the actual situation is often limited by conditions and does not have the excavation condition; and space transfer, namely a shared single-vehicle storage regulation point provided by the invention, effectively links the high demand point and the low demand point to realize space balance between supply and demand.

Detailed Description
Example 1
As shown in fig. 1, a shared bicycle storage point planning and site selection method; the method comprises the following steps:
step 1, judging and calculating the scale of the required regulation and storage of the parking conflict points;
step 2, selecting a regulation and storage road section;
step 3, determining the scale of the containable shared bicycle of the regulation and storage road section;
step 4, selecting a shared bicycle storage regulation point; and (4) selecting the address of the shared bicycle regulating and storing point according to the regulating and storing road section selected in the step (3) and the size of the receivable shared bicycle determined in the step (3).
The shared single-vehicle storage regulation point is a non-motor vehicle parking point which is arranged on a secondary branch road with small motor vehicle traffic flow and non-motor vehicle parking requirements and used for temporarily parking the shared single vehicle, and aims to solve the problems that the shared single-vehicle parking requirement tide characteristics are obvious and the parking overflow is severe in peak periods in rail transit stations, large commercial buildings and the like, and the shared single vehicle is taken as a service object, a manager transfers vehicles as an operation means and stores the shared single vehicle for a short time.
Based on the idea, the storage regulation point has the following three remarkable characteristics:
1) is arranged in the road. The shared bicycle has a public attribute and occupies a public space for parking. As a parking place for temporarily storing and sharing the bicycle, public space resources need to be relied on. The public space of the road has the public service attribute for bearing the parking of the non-motor vehicles, so that the shared single-vehicle regulation and storage point is selectively arranged in the road, but the essence of the regulation and storage point is still the parking point of the non-motor vehicles in the road, and the addition of the attribute of the regulation and storage point does not influence the use of the function of the non-motor vehicle parking point and the use of the pedestrian and vehicle functions in the road.
2) The regulation object is a shared bicycle. The non-motor vehicles parked at a rail transit station or the like include not only shared vehicles but also private non-motor vehicles of urban residents, but the private nature of the private non-motor vehicles requires that they cannot be transferred, and therefore, after the parking overflow problem occurs, the target vehicles for regulation can only be shared vehicles having public attributes.
3) The vehicle needs to be dispatched by a manager. The non-motor vehicle travelers are on the principle of parking nearby, and even if there is not enough parking place nearby, the users can pile up the non-motor vehicle travelers nearby. Therefore, the regulation and transfer of the shared bicycle needs to be realized by means of transfer of management personnel. In general, after the problem of parking overflow occurs, a manager loads the shared bicycle into a transfer vehicle and transports the shared bicycle to a storage regulation point for temporary parking. In consideration of the parking requirements of the transfer vehicles, the road section where the storage regulation point is located is not a high-grade road with large traffic volume.
On the basis, the invention provides a planning and address selecting method for shared bicycle storage points, which is mainly applicable to judging the scale of storage to be regulated aiming at the point positions with prominent contradiction between parking of specific shared bicycles, searching and selecting a proper storage section, guiding the transfer operation of managers and realizing the balance of supply and demand of the shared bicycles.

the road grade D comprises an express way, a main road, a secondary road and a branch; the express way, the main trunk way, the secondary trunk way and the branch way respectively correspond to weight values of 1, 2, 3 and 4;
the judgment formula of the road section meeting the setting requirement of the shared single-vehicle storage regulation point is as follows:
