Problems solved by technology
[0010] The technology of the present invention solves the problem: Aiming at the serious problem of stringing vehicles on current bus lines, which leads to the problem of low service efficiency, the shuttle bus dispatching mode is introduced to change the existing, single full bus dispatching mode, and a combined dispatch based on the shuttle bus and the full bus is provided Optimal method for stringing trains on bus lines

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 invention relates to a bus route crossing optimization method based on whole-journey bus and inter-region bus combined scheduling. The method comprises the following steps: definitely adjusting part of whole-journey bus passes into inter-region bus passes on the basis that the number of existing passes of a bus route is not changed, and reducing crossing through the whole-journey bus and inter-region bus combined scheduling; analyzing the historical IC card data and the GPS data of the bus route to determine the starting station and the trip number of the inter-regional bus; establishing amathematical model aiming at minimizing the deviation between departure time and planned time of each trip for a departure station of an inter-zone vehicle; and converting the established model intoa mixed integer linear programming, and solving the mixed integer linear programming by using a branch and bound algorithm to obtain a combined scheduling scheme of the whole-process vehicle and the inter-region vehicle. Under the background of increasingly serious urban bus line crossing, the distribution of transport capacity on different road sections is adjusted by adopting a whole-course busand inter-regional bus combined scheduling method, so that the service reliability and the service efficiency of bus lines are improved. The method has superiority in the aspect of reducing the crossing times of the 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...
