the calculation method comprises the following steps:
s11, calculating delay of buses entering the intersection;
the specific calculation method is that the satellite positioning data of the buses are used for counting the time when a certain vehicle enters and exits a certain intersection within a certain time; calculating a delay of the vehicle entering the intersection: (exit time-entry time) - (intersection distance/vehicle speed), wherein the exit time-entry time is the time of passing through the intersection, and the intersection distance/vehicle speed is the time of passing through the intersection in an ideal state.

the specific calculation method is that the number of people on the vehicle passing through the intersection in the period is calculated by using the satellite positioning data of the bus and the IC card data of the bus, and the delay of all people on the bus=the delay of the vehicle.
It should be further noted that, generally, bus IC card data and bus satellite positioning data (satellite positioning data has GPS data or beidou data) are used to count the number of passengers on buses and the number of passengers off buses, so that the number of passengers on buses is further counted, for example, taking a ticket-made bus route, and since the passengers do not need to swipe cards, there is no information on the passengers in the swipe records, and the bus stop cannot be calculated by the card swiping time like calculating the bus stop, so that the passenger information of the bus route needs to be obtained by further combining GPS data, subway gate data and even mobile phone signaling data and fusion mining of multi-source data, and the characteristics of the city buses, such as certain regularity, stability and preference on the bus trip route selection and passenger flow distribution, are determined, and the bus stop is calculated by adopting a method based on trip chains and on stop attraction.
For example, a person takes a bus to work in the morning and takes a bus to work in the evening, so that a passenger point in the morning and a passenger point in the evening are possible, and the passenger point is judged by taking a trip behavior of a plurality of days, and meanwhile, if the transfer of the bus is involved, a transfer point can be judged according to a transfer field in an ic card, and the transfer point is the passenger point with high probability.
S13, calculating delays of all people on all buses of each entrance way;
the specific calculation method is that delay of all persons on all buses entering an entrance where the intersection is located in a certain time is counted, namely, delay of persons of a vehicle 1, delay of persons of a vehicle 2, delay of persons of a vehicle 1, a vehicle 2 and a vehicle … …, wherein the vehicle N is a vehicle entering the entrance in the counting period, and the vehicle N is the number of vehicles entering the entrance in the counting period.
S14, calculating delays of all people on all buses at each intersection;
the specific calculation method is that delay of all persons on buses entering the intersection in a certain time is counted, namely delay of an entrance lane 1, delay of an entrance lane … … and delay of an entrance lane N, wherein the entrance lane 1, the entrance lanes 2 and … … are all arranged, the entrance lane N is the entrance lane of the intersection, and the N is the number of the entrance lanes of the intersection.
S2, selecting the intersection which should be set with priority according to the comprehensive delay of the intersection, wherein the intersection is set with priority according to the comprehensive delay descending order and the intersection setting condition.
The invention calculates the comprehensive delay of the intersection by utilizing the satellite positioning data of the buses and the IC card data of the buses, including calculating the delay of the buses entering the intersection; calculating delays of all people on each bus; calculating delays of all people on all buses of each entrance way; calculating delays of all people on all buses at each intersection; according to the comprehensive delay of the intersections, the intersections with the priority of buses are selected, the invention can provide basis for the selection and treatment of the urban public traffic priority intersections, and the satisfaction of the travel of the passengers in buses is improved.
