1. A driving timetable generation method, comprising steps of:
acquiring a preset driving route of a public transport vehicle, wherein the driving route comprises multiple stations;
extracting, in a direction from a starting station to a terminal station in the multiple stations, driving intervals of two adjacent stations in the driving route sequentially;
determining, for each driving interval, a driving duration for the public transport vehicle to pass through the driving interval according to interval attribute of the driving interval;
calculating, on the basis of a preset departure moment of the public transport vehicle and the driving duration of each of the driving intervals corresponding to the departure moment, time information about the public transport vehicle arriving at each of the stations in the driving route corresponding to the departure moment; and
generating, according to the time information, the driving timetable corresponding to the departure moment of the public transport vehicle on the current driving route;
wherein the step of determining a driving duration for the public transport vehicle to pass through the driving interval according to an interval attribute of the driving interval comprises:
planning the driving interval according to the interval attribute, so as to obtain multiple interval road sections; and
calculating, on the basis of a standard driving speed curve of the interval road section, a driving duration for the public transport vehicle to pass through the driving interval;
wherein the interval attribute comprises intersection information and/or speed limit zone information; and the step of planning the driving interval according to the interval attribute comprises:
determining separation points of the driving interval according to the interval attribute, wherein the separation points comprise intersections and/or speed limit zones; and
dividing the driving interval into multiple interval road sections according to the separation points;
wherein the step of calculating, on the basis of a standard driving speed curve of the interval road sections, a driving duration for the public transport vehicle to pass through the driving interval comprises:
acquiring starting position, end position, starting speed, end speed, starting moment, acceleration, and platform speed of interval road sections, and generating the standard driving speed curve of the interval road sections, wherein an initial value of the interval road section platform speed is an average traffic speed;
calculating, on the basis of the standard driving speed curve, an interval road section end moment of each of the interval road sections;
obtaining, according to an end moment of each interval road section in a current driving interval, time information about the public transport vehicle arriving at the terminal station corresponding to the current driving interval; and
calculating, according to the time information about the starting station corresponding to the current driving interval and time information about the terminal station corresponding to the current driving interval, the driving duration for the public transport vehicle to pass through the current driving interval, wherein the time information about the starting station corresponding to the current driving interval is the time information about the public transport vehicle arriving at the terminal station corresponding to the previous driving interval.
