Embodiment Construction
[0076] The content of the present invention will be described in detail below in conjunction with specific examples.
[0077] The current bus lines generally use a single dispatch mode for the whole bus. The bus starts from the first station and returns after arriving at the last station. For example, figure 2 shown. Affected by some congested road sections, the vehicles that depart at even intervals become uneven during the driving process, and in severe cases, a string of vehicles will form, such as image 3 shown. Aiming at this phenomenon, the present invention introduces the shuttle bus dispatching mode into the bus line to solve the problem of "stringing cars" in the running process of the bus vehicles. Such as figure 2 As shown, the shuttle bus dispatching mode means that the bus departs from the first station and turns back after arriving at a certain station in the middle, or directly departs from a certain station in the middle until it reaches the terminal stat...

The present invention relates to a method for optimizing bus line stringing trains based on the combined scheduling of full-time trains and section trains. , using the combined dispatch of full-time trains and shuttle buses to reduce the number of trains; by analyzing the historical IC card data and GPS data of the bus line, determine the starting station and the number of trips of the shuttle bus; for the departure of the shuttle bus Station, establish a mathematical model with the goal of minimizing the deviation between the departure time of each trip and the planned time; convert the established model into a mixed integer linear programming, use the branch and bound algorithm to solve it, and get the whole journey Combination scheduling scheme of bus and shuttle bus. The present invention mainly adopts the method of combined dispatching of full trains and section trains to adjust the distribution of transport capacity on different road sections under the background that the problem of stringing trains on urban bus lines is becoming more and more serious, so as to improve the service reliability and service efficiency of the bus lines. This method has advantages in reducing the number of trains on bus lines.
Description
technical field [0001] The present invention provides a method for optimizing bus line stringing based on the combined scheduling of full-time trains and local trains, which adjusts part of the full-time train trips of the bus line to local train trips, so that it can skip road sections that are prone to congestion and allow passengers to get on and off Stations where the number of vehicles is less than a certain threshold, thereby reducing the number of trains on the bus line, belong to the technical field of urban public transportation; use historical IC card data and GPS data to determine the originating station and the number of trips of the shuttle bus; At the departure station, a mathematical model with the goal of minimizing the deviation between the departure time of each trip and the planned time is established, and the departure time of each trip of the whole train and the section train is obtained. Background technique [0002] With the rapid development of my cou...
