As shown in fig. 1, the method is applied to a server, and includes:

s101, acquiring target road information related to a toll station.

In one embodiment, the target road information includes lane information of sections of entrance and exit upstream lanes of the toll station, wherein the number of roads of the entrance lane and the exit lane can be set according to actual requirements.

S102, processing the target road information based on a preset processing rule to generate real-time traffic flow information.

In one embodiment, based on annual traffic data of nearly two years, only day and time are extracted as discrete features, and the service time of the non-free flow ETC lane is 2-3 s, the service time of the closed interchange entrance is 6-8 s and the service time of the exit is 14-20 s according to the calculation of the technical requirement of the networking charging of toll roads. In addition, the preset processing rule comprises a calculation formula for acquiring real-time traffic flow information, wherein the calculation formula is as follows: ddhv=aadt K/>D, a step of performing the process; wherein DDHV is unidirectional design hour traffic (pcu/h); AADT is the average daily traffic volume per year predicted (pcu/d); k is the traffic coefficient of the design hour; d is the traffic direction non-uniformity coefficient.

And S103, processing the real-time traffic flow information based on a preset road traffic flow calculation model to generate real-time entrance and exit vehicle information and real-time entrance and exit road information.

In one embodiment, the toll station plaza planning design does not consider the reciprocating lane and the single island multi-pavilion lane, and has no practical significance when the real-time traffic flow data DDHV value exceeds 9000. The preset road traffic flow calculation model comprises a traffic flow lane number calculation simulation table, the service time of an entrance is anchored manually, the total number of unidirectional lanes is obtained by looking up a table according to actual traffic flow data, and the bidirectional lane number is obtained according to the method. For example, when the real-time traffic flow data is 300 and the traffic service duration of a single vehicle is 6 seconds, the number of unidirectional lanes is 1; when the real-time traffic flow data is 230 and the traffic service time of a single vehicle is 8 seconds, the number of the unidirectional lanes is 1. When the real-time traffic flow data is 847 and the traffic service duration of a single vehicle is 6 seconds, the number of the unidirectional lanes is 2; when the real-time traffic flow data is 640 and the traffic service time of a single vehicle is 8 seconds, the number of unidirectional lanes is 2. When the real-time traffic flow data is 2000 and the traffic service time of a single vehicle is 6 seconds, the number of unidirectional lanes is 4; when the real-time traffic flow data is 1500 and the traffic service time of a single vehicle is 8 seconds, the number of unidirectional lanes is 4. When the real-time traffic flow data is 5560 and the traffic service duration of a single vehicle is 6 seconds, the number of unidirectional lanes is 10; when the real-time traffic flow data is 4170 and the traffic service duration of a single vehicle is 8 seconds, the number of unidirectional lanes is 10. In addition, the real-time entrance/exit vehicle information includes real-time exit vehicle information and real-time entrance vehicle information, and the real-time entrance/exit road information includes real-time exit road information and real-time entrance road information.

And S104, if the ratio of the traffic flow of the real-time exit vehicle information to the traffic flow of the real-time entrance vehicle information in the preset time period is greater than a preset threshold value, generating a tide lane rule.

In one embodiment, during holidays such as spring festival and eleven, the traffic flow of the highway toll station always presents tidal characteristics, and in order to ensure smooth bidirectional traffic, it is necessary to specifically analyze the traffic flow of the toll station holiday, and start tidal toll lane measures for the toll station which presents remarkable tidal characteristics for the bidirectional traffic flow, so as to meet the temporary tidal traffic flow to meet the traffic demand and balance the bidirectional traffic pressure. For example, when the entrance lanes are arranged in a large team and the exit lanes are sporadically arranged for a few vehicles, part of the exit lanes are adjusted to be positioned in the entrance lanes, and the exit lane information and the entrance lane information are adjusted according to the actual traffic flow. If the sum of the number of the two-way lanes obtained by calculating the simulation table according to the number of the traffic lanes is less than or equal to the total number of the lanes of the toll station, the tidal adjustment is directly carried out on the toll lanes of the existing gateway according to the result of the number of the simulation lanes; if the sum of the number of the two-way lanes is larger than the sum of the lanes of the toll station, tidal adjustment is carried out on the existing entrance toll lanes according to the ratio of the number of the simulated lanes.

In one embodiment, the target entrance lane information includes pre-processed target exit lane information and target entrance lane information. The toll lanes which show remarkable tidal characteristics for the bidirectional traffic flow are set as tidal lanes, and on N tidal lanes, outfield arrangement is carried out according to N ETC lanes and 2N entrance card issuing devices respectively.

When the toll collector uses, the toll collection software, ETC road side unit controller, railing machine and the like in one direction are closed, the other direction operates normally, the tidal lane follows the principle of moderate starting from inside to outside, and when the toll collector is opened, the toll collector needs to cooperate with a variable information board, traffic broadcasting, an Internet platform (Goldd, hundred degrees) and the like which are 5-10km upstream in two directions to develop early warning prompts. The principle of moderate starting from inside to outside means that when vehicles of the entrance lane on the right side are long in a queue, and vehicles of the exit lane on the left side are only sporadically used, the exit lane close to the entrance lane on the right side is adjusted to be the entrance lane. The inner side from inside to outside refers to the side close to the bidirectional dividing strip, and the adjustment of the tide lane is started from the side close to the dividing strip; moderate means that the traffic is redistributed according to the proportion of the bidirectional traffic flow, and excessive traffic cannot be set, which would affect the traffic speed of the opposite vehicles, so that the toll station is jammed on the other side.

The method comprises the steps that a server obtains target road information related to a toll station; processing the target road information based on a preset processing rule to generate real-time traffic flow information, wherein the preset processing rule comprises a calculation formula for acquiring the real-time traffic flow information, and the calculation formula is as follows: ddhv=aadtK/>D, a step of performing the process; processing the real-time traffic flow information based on a preset road traffic flow calculation model to generate real-time entrance and exit vehicle information and real-time entrance and exit road information, wherein the real-time entrance and exit vehicle information comprises real-time exit vehicle information and real-time entrance vehicle information, and the real-time entrance and exit road information comprises real-time exit road informationInformation and real-time entry road information; if the ratio of the traffic flow of the real-time exit vehicle information to the traffic flow of the real-time entrance vehicle information in the preset time period is larger than a preset threshold value, generating a tide lane rule; and processing the real-time entrance road information based on the tide lane rule to generate target entrance lane information, wherein the target entrance lane information comprises the preprocessed target exit lane information and the preprocessed target entrance lane information. According to traffic flow data of the sections of the entrance and exit upstream lanes of the toll station, the expected traffic flow ratio of the entrance and exit is calculated, if the situation that the traffic flow ratio of the entrance and exit is not matched with the number of opening lanes of the entrance exists, the number of the toll lanes of the entrance can be increased or decreased by adjusting the direction of the toll lanes, and tidal toll lane measures are opened by the toll station which shows remarkable tidal characteristics for the bidirectional traffic flow, so that the temporary tidal traffic flow meets the traffic demand, and the bidirectional traffic pressure is balanced.

In another embodiment, an adjustment result is generated based on the first adjustment information, and when the adjustment result is insufficient to solve the abnormal state, other roads with the distance between the road information corresponding to the target event information and the target range threshold value are acquired, and the other roads are processed based on a preset adjustment rule to generate the second adjustment information. The server judges whether the congestion condition of the road information corresponding to the target event information is relieved, if the road information is in the congestion state for a long time, the server acquires the connected road sections with the accident road sections in the accident influence range, judges the congestion condition of the connected road sections, and selects the shuntable road to remind the running. The server screens roads adjacent to the road information corresponding to the target event information based on a route nearest principle, wherein the route nearest principle is to split the road with the vehicle of the road section to be split being nearest, if the split vehicle of the nearest road is saturated, then the second nearest road is selected for splitting, and so on.
