Examples:
In the embodiment provided by the invention, besides considering the current real-time road surface condition, the historical running tracks of all vehicles currently positioned on the planned running route are counted, the historical running tracks of the vehicles on the planned running route are determined in a fitting way according to the historical running tracks, and track points positioned in the emergency stop zone T1 … … Tn are generated based on a plurality of historical running tracks, and the method is specific:
The summary data in the above embodiment includes a historical travel track under the planned travel route under the historical data, and historical traffic flow data corresponding to a period under the historical travel track.
The historical traffic flow data of the corresponding time period under the historical driving track comprises an idle time track and a busy time track, wherein the busy time track is the peak trip of the holiday time period, and the idle time track is the trip of the non-holiday time period, wherein the idle time track is the peak trip of the holiday time period:

and reminding the vehicles running on the important T-point road section, and improving and preventing the emergency stop with the vehicles from running in.
In the above technology, the point location arrangement condition of the emergency stop zone T1 … … Tn along the road is determined according to the dynamic planned driving route, and a dynamic vehicle management model of the current planned driving route is generated based on the summarized data, then, according to the history data of the vehicle, whether the current vehicle has frequent driving in the emergency stop zone is judged, and the driving in Tn and the driving out Tn corresponding to T1 … … Tn are found, so that the vehicles in the areas of the driving in Tn and the driving out Tn are reminded.
Examples:
When a plurality of historical driving tracks of all vehicles on a planned driving route are acquired, fitting is required to the plurality of historical driving tracks, so that a predicted track point sequence number is given. In step S03 of the first embodiment, a prediction result sequence under the grid model is generated, which at least includes a plurality of historical driving tracks, a repetition probability calculation for each point of T1 … … Tn under the plurality of historical driving tracks is calculated, and the number of times is divided by the sum of the straight line distances between the track and T under the plurality of historical driving tracks to obtain a trigger value;

In step S04 of the first embodiment, the regional interval between each T based on T1 … … Tn is 500m.
That is, if the trigger value of T1 is calculated, several historical driving tracks of adjacent periods are taken, if five times are taken, the five historical driving tracks are added and divided by five to obtain an average value, that is, when the vehicle passes through T1 again, as long as the vehicle is in the lane covered by the average value, the vehicle can enter, and the vehicle can exit according to the method.
And determining the trigger value so as to select the point position positioned at T in the similar track, and then determining the residual driving route positioned at the point position of T through a threshold value so as to generate the driving track. And the embodiment is applied to the analysis of the predicted track point sequence number of the busy hour track.
According to whether the current time period of the vehicle is holidays or not and according to judgment, the first reference data and the second reference data are started as reference to set the track point serial numbers, so that sensitivity management is enhanced on the vehicle with driving preference, monitoring is enhanced, and the vehicle is prevented from frequently driving into an emergency stop zone.
Examples:
As can be seen from fig. 2, the planned T entry and exit points are given based on the similar trajectory c, the T point area requiring attention for entry and exit is given by the average driving speed, the meeting time based on the current driving speed of the vehicle is given, the predicted track point numbers acquired in step S05 are displayed, the first reference data and the second reference data are selected to be enabled as the reference planned track point numbers based on the driving time period, and the entry and exit time points of the track point numbers are dynamically simulated based on the average driving speed.
And the emergency stop zone violation snapshot area under the T1 … … Tn is marked and is set as a sensitive area a 1……an, and the position of the point a under the track point serial number is set. And identifying a plurality of violation snapshot areas under the planned driving route to determine the quantity of a existing in the T, carrying out early warning prompt when the driving vehicle time period is in holidays and approaches to the starting position of the a point, dynamically simulating the driving in and out time points of the track point serial numbers according to the average driving speed, acquiring the average speed of the vehicle approaching the T lane, giving out the meeting time of the two points, and carrying out feedback prompt.
It should be noted that, the point a includes a security area, and when the first reference data is taken as a reference, the point a is 500m; the second reference data is 800m. When a plurality of T points are arranged, the point a is added, and the condition that the vehicle is driven into an emergency stop zone cannot necessarily occur because the point a is a camera. The point a can be timely incorporated when the vehicles with the track are fewer in idle time, and the safety area of the point a is 800m when the second reference data is used as a reference because the vehicles with the track are more in emergency stop zone and the vehicles with the track are required to be incorporated into the main lane in advance when the vehicles are in busy time.
