Description

Technical Field

[0001] The invention belongs to the field of intelligent transportation, and in particular relates to an intercity bus system based on module vehicles. Background Art

[0002] The modular vehicle is composed of a single or several modular units, each of which has a certain passenger carrying capacity. The modular vehicle can have the ability to drive autonomously. All modular vehicles in this patent can achieve the highest level of autonomous driving. The modular vehicle can separate and connect modular units during driving, dynamically adjust vehicle formation, and transfer passengers between different modular vehicles. The schematic diagram of the modular vehicle is shown in the figure. Figure 1 shown.

[0003] With the increasing demand for personalized travel, traditional intercity transportation methods, such as intercity railways, high-speed railways and long-distance buses, have problems such as insufficient flexibility, low convenience and high transfer costs. The potential market demand for more flexible and efficient intercity transportation solutions is huge, and the construction of an intercity modular bus system based on modular vehicles may become an important solution.

[0004] Modular buses are currently mainly used for urban transportation, such as Figure 2 As shown. The modular bus system in the city achieves dynamic capacity adjustment through the separation and connection of vehicle module units. It can be reorganized and disorganized at the station, and the number of groups can be flexibly adjusted according to the passenger capacity. The use of modular buses in the city can shorten the stop time and waiting time, and can also effectively avoid the phenomenon of crowded carriages during peak hours and high empty load rates during off-peak hours of conventional buses, and can cope with unbalanced and asymmetric travel needs.

[0005] However, the distribution of travel demand within the city is random, there is no obvious traffic corridor, and the departure point and destination may be far away from the modular bus lines and stations, making it difficult to provide a completely "point-to-point" passenger pick-up and drop-off service. If the modular bus system in the city provides "point-to-point" passenger pick-up and drop-off without a significant traffic corridor, it will need to frequently combine and split modules, which will interfere with road traffic, may aggravate congestion, and have poor operating results. However, the distribution of inter-city travel demand is more concentrated, there are obvious traffic corridors, and the modular units do not need to be frequently split and combined, which has less impact on road traffic order. In addition, the highway environment is relatively closed, and modular vehicles are more convenient for separating and connecting modular vehicle units in inter-city travel. Summary of the invention

[0006] The purpose of the present invention is to provide an intercity bus system based on modular vehicles in view of the deficiencies of the prior art.

[0007] The object of the present invention is achieved through the following technical solutions: an intercity bus system based on modular vehicles, the system comprising an intercity bus system based on modular vehicles including a modular bus passenger pick-up and drop-off subsystem in urban roads, a modular vehicle optimization grouping subsystem at a highway entrance and exit control point, and a modular vehicle optimization grouping subsystem at a hub interconnection control point;

[0008] The modular bus passenger pick-up subsystem in the urban road is used to select modular vehicles to pick up passengers at designated locations after passengers publish travel needs on the travel service platform; to send passengers to the nearest highway entrance control point through modular vehicles; or to send passengers to their destinations in the city based on real-time monitoring and optimized scheduling of vehicle and road conditions after the modular vehicle group completes the highway section and arrives at the highway exit control point;

[0009] The module vehicle optimization marshaling subsystem at the entrance and exit control point of the expressway is used to implement the disassembly of multiple module vehicles arriving at the entrance control point of the expressway: the module vehicle combination with the same destination is adjusted and connected together to form a module vehicle marshaling, and passengers are guided to complete the mobile transfer between module units according to the arrival city, and after the unloaded module units are disassembled, the departure task of the module vehicle marshaling is prepared; or it is used to combine with the module bus passenger pick-up and drop-off subsystem on the urban road to dispatch and reconnect the passengers in the module vehicle marshaling arriving at the expressway exit control point according to the specific destination of the passenger, and after completing the mobile transfer of the passengers, the disassembly and delivery task of the module unit is implemented;

[0010] The hub interchange control point module vehicle optimization marshaling subsystem is used to optimize the module vehicle marshaling when the module vehicle marshaling arrives at the hub interchange control point of the urban highway.

[0011] Furthermore, the modular vehicle is composed of a single or multiple modular units.

[0012] Furthermore, the modular bus passenger pick-up subsystem in the urban road is used to select modular vehicles to go to the designated location to pick up passengers after the passengers publish their travel needs on the travel service platform; and send the passengers to the nearest highway entrance control point through the modular vehicles, specifically:

[0013] When passengers publish travel needs on the travel service platform a Then, the modular bus passenger pick-up and drop-off subsystem in the urban road determines whether there is an unfilled modular vehicle M at the boarding point of passenger a and the travel demand of modular vehicle M is the same as r according to the operating status of all modular vehicles in the road network. a: If yes, the modular bus passenger pick-up and drop-off subsystem in the urban road dispatches a modular vehicle M to pick up passenger a; if not, the modular bus passenger pick-up and drop-off subsystem in the urban road dispatches a modular vehicle M' that is not full to pick up passenger a according to the shortest path principle; after picking up passenger a, the modular vehicle that picks up passenger a sends passenger a to the nearest highway entrance control point.

[0014] Furthermore, the modular bus passenger pick-up and drop-off subsystem in the urban road is used to send passengers to their destinations in the city according to real-time monitoring and optimized scheduling of vehicle and road conditions after the modular vehicle marshaling completes the highway section and arrives at the highway exit control point, specifically:

[0015] When the modular vehicle group completes the highway section and arrives at the highway exit control point, the modular bus passenger pick-up and drop-off subsystem in the urban road assigns each passenger to the corresponding modular unit, and then organizes the modular units with the same destination into modular vehicles, which then transport each passenger to the corresponding destination.

[0016] Furthermore, the module vehicle optimization marshaling subsystem at the entrance and exit control point of the expressway is used to reorganize multiple module vehicles arriving at the entrance control point of the expressway: the module vehicles with the same destination are combined and connected together to form a module vehicle marshaling, and passengers are guided to complete the transfer between module units according to the arrival city, and the unloading module units are disassembled to prepare for the departure task of the module vehicle marshaling, specifically:

[0017] (b.1) The expressway entrance and exit control point module vehicle optimization marshaling subsystem is used to number the module vehicles according to the time when the module vehicles arrive at the expressway entrance control point within a unit time τ for N module vehicles with the same destination in the same direction arriving at the same expressway entrance control point;

[0018] (b.2) Then, each of the N modular vehicles is sequentially demultiplexed into a single modular unit. If there are multiple modular units in the modular vehicle, the corresponding demultiplexing completion time is obtained according to the sequence of different modular units in the same modular vehicle; after the demultiplexing is completed, all modular units are numbered according to the demultiplexing completion time of each modular unit;

[0019] (b.3) Then, according to the distance of the passenger's destination city in each module unit and the module unit number, all the module units are connected in sequence to form a module vehicle group, and then all the module units in the module vehicle group are renumbered in a front-to-back order;

[0020] (b.4) Determine the number of module units going to each city based on the travel demand summary within the unit time τ;

[0021] (b.5) Based on the module unit number and the destination of each module unit, issuing carriage information to guide passengers to move to the corresponding module unit;

[0022] (b.6) After the passengers have completed their movement, the unloaded module units in the module vehicle formation are separated from the module vehicle formation to obtain a module vehicle formation after de-formation. The separated module units wait to be assigned other pick-up and drop-off tasks;

[0023] (b.7) After the disassembly is completed, the modular vehicle group is ready to depart and then drive to the destination.

[0024] Furthermore, the module vehicle optimization marshaling subsystem at the highway entrance and exit control point is used to combine with the module bus passenger pick-up and drop-off subsystem on the urban road to dispatch and reconnect the passengers in the module vehicle marshaling arriving at the highway exit control point according to the specific destination, and after completing the mobile transfer of the passengers, implement the module unit's passenger disassembly and delivery tasks, specifically:

[0025] (c.1) The modular vehicle optimization marshaling subsystem at the highway entrance and exit control point is combined with the modular bus passenger pick-up and drop-off subsystem on the urban road to determine the modular vehicle marshaling arriving at the highway exit control point. The modular units for picking up and dropping off passengers are first determined: according to the travel needs of all passengers in the modular vehicle marshaling, the city destinations are statistically summarized, and the city destinations are sorted from far to near and numbered in sequence. Then, the number of modular units going to each city destination is calculated according to the number of passengers in the modular vehicle marshaling and the capacity of each modular unit;

[0026] (c.2) If the sum of the number of modular units going to each destination in the city is greater than the sum of the number of modular units in the modular vehicle formation, the number of modular units that need to be dispatched is calculated, and the nearby idle modular units are dispatched to the highway exit control point in advance based on the shortest path principle; then the modular vehicle formation and the dispatched modular units are connected to obtain the connected modular vehicle formation, and then all the modular units in the connected modular vehicle formation are numbered in sequence;

[0027] If the sum of the number of modular units going to various intra-city destinations is less than the sum of the number of modular units in the modular vehicle formation, all modular units in the modular vehicle formation are directly numbered in sequence;

[0028] (c.3) After completing the numbering of the module units, according to the number of each module unit and the corresponding destination in the city, the carriage information is released to guide passengers to move to the corresponding module unit;

[0029] (c.4) All the modular units in the modular vehicle formation are then de-massembled, and each modular unit transports passengers to a specific destination within the city.

[0030] Furthermore, the hub interchange control point module vehicle optimization marshaling subsystem is used to optimize the module vehicle marshaling after the module vehicle marshaling arrives at the hub interchange control point of the urban highway passing through, specifically:

[0031] (d.1) The urban highway hub interchange control point is divided into a front disassembly area and a reconnection area. When the modular vehicle marshaling from different cities arrives at the front disassembly area of ​​the highway hub interchange control point in the same city within a unit time τ, the hub interchange control point modular vehicle optimization marshaling subsystem disassembles the corresponding modular units in all modular vehicle marshaling according to the different cities that can be reached through the highway hub interchange control point, and ensures that the modular units going to the same city remain connected after disassembly;

[0032] (d.2) When modular vehicle groups from different cities arrive at the reconnection area of ​​the highway hub interchange control point in the same city within a unit time τ, the hub interchange control point modular vehicle optimization grouping subsystem will merge and reconnect different modular units going to the same city according to the order of arrival time and the distance from the corresponding city to form a modular vehicle group, and then advance the merged and reconnected different modular vehicle groups to the corresponding city.

[0033] The beneficial effects of the present invention are:

[0034] 1) The system can provide "point-to-point" personalized and customized travel services according to passengers' travel needs, reduce passengers' waiting time and transfer time, and improve passengers' travel experience;

[0035] 2) The system can adjust the module unit configuration and module vehicle operation line optimization according to traffic demand, reduce the empty load rate by dynamically optimizing the vehicle formation, and optimize the module unit resource utilization;

[0036] 3) The system can reduce energy consumption and carbon emissions by optimizing operations, and is environmentally friendly;

[0037] 4) The present invention can effectively improve passenger transport efficiency, reduce operating costs, and provide high-quality passenger services through intelligent, modular, and dynamic vehicle formation and dispatching mechanisms, while taking into account the protection of the natural environment; these beneficial effects make the system have important application prospects and promotion value in the field of modern intelligent transportation.

[0054] In order to make the purpose, technical scheme and advantages of the present invention more clear, the present invention is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] Example 1

[0056] like Figure 3 As shown, the present invention provides an intercity bus system based on modular vehicles, which includes a modular bus passenger pick-up and drop-off subsystem in urban roads, a modular vehicle optimization grouping subsystem at highway entrance and exit control points, and a modular vehicle optimization grouping subsystem at hub interchange control points.

[0057] The modular bus passenger pick-up and drop-off subsystem in the urban road is used to select modular vehicles to go to the designated location to pick up passengers after passengers publish travel needs on the travel service platform; to send passengers to the nearest highway entrance control point by modular vehicles; or to send passengers to their destinations in the city based on real-time monitoring and optimized scheduling of vehicle and road conditions after the modular vehicle group completes the highway section and arrives at the highway exit control point.

[0058] The modular vehicle is composed of a single or multiple modular units.

[0059] The modular vehicle optimization marshaling subsystem at the highway entrance and exit control point is used to implement marshaling of multiple modular vehicles arriving at the highway entrance control point: the modular vehicle combination with the same destination is adjusted and connected together to form a modular vehicle marshaling, guiding passengers to complete the mobile transfer between modular units according to the arrival city, and preparing the departure task of the modular vehicle marshaling after the unloaded modular units are disassembled; or when the modular vehicle marshaling completes the highway section and arrives at the highway exit control point, it is used to send passengers to the destination in the city according to the real-time monitoring and optimized scheduling of the vehicle and road conditions.

[0060] The hub interchange control point module vehicle optimization marshaling subsystem is used to optimize the module vehicle marshaling when the module vehicle marshaling arrives at the hub interchange control point of the urban highway.

[0061] 2. Modular bus passenger pick-up and drop-off subsystem in urban roads

[0062] The modular bus passenger pick-up and drop-off subsystem in the urban road mainly includes two tasks:

[0063] a.1) When a passenger publishes a travel demand on the travel service platform, the modular public transportation passenger pick-up subsystem on the urban road selects a modular vehicle to go to the passenger's departure point to pick up the passenger. During the passenger pick-up process, the optimal modular vehicle is dynamically dispatched according to the real-time traffic conditions and the passenger's location to ensure that the passenger pick-up task can be completed as soon as possible; then the passenger is sent to the nearest highway entrance control point by the modular vehicle. Specifically:

[0064] When passenger a publishes travel demand r on the travel service platform a Then, the modular bus passenger pick-up and drop-off subsystem in the urban road determines whether there is an unfilled modular vehicle M at the boarding point of passenger a and the travel demand of modular vehicle M is the same as r according to the operating status of all modular vehicles in the road network. a : If yes, the modular bus passenger pick-up and drop-off subsystem in the urban road dispatches a modular vehicle M to pick up passenger a; if not, the modular bus passenger pick-up and drop-off subsystem in the urban road dispatches a modular vehicle M' that is not full to pick up passenger a according to the shortest path principle; after picking up passenger a, the modular vehicle that picks up passenger a sends passenger a to the nearest highway entrance control point.

[0065] a.2) The task of sending passengers to the destination point after the modular vehicle exits the highway: When the modular vehicle group completes the highway section and arrives at the highway exit control point, the modular bus passenger pick-up and drop-off subsystem in the urban road assigns the modular vehicle to send passengers to the destination in the city. This process also relies on the real-time monitoring and optimized dispatch of the modular bus passenger pick-up and drop-off subsystem in the urban road according to the vehicle and road conditions to ensure that passengers can reach the destination as quickly and safely as possible. Specifically:

[0066] When the modular vehicle group completes the highway section and arrives at the highway exit control point, the modular bus passenger pick-up and drop-off subsystem in the urban road assigns each passenger to the corresponding modular unit, and then organizes the modular units with the same destination into modular vehicles, which then transport each passenger to the corresponding destination.

[0067] For the same city, there are both departure and arrival passengers, that is, the entrance control point of the expressway is also the exit control point of the expressway. The departure and arrival points of passengers are randomly distributed in time and space.

[0068] The entrance and exit control points of expressways are important nodes for realizing the dynamic optimization of vehicle and passenger grouping. At these nodes, the optimization grouping of modular vehicles within a certain time window is completed.

[0069] At the entrance and exit control points of the expressway, the modular vehicles have not yet entered the expressway system and the speed is slow, so passengers are allowed to transfer between vehicle modules. Therefore, the joint optimization of "module vehicle grouping" and "passenger-module reorganization" is implemented at the entrance and exit control points of the expressway.

[0070] The module vehicle optimization marshaling subsystem at the entrance and exit control point of the expressway is used to implement the disassembly of multiple module vehicles arriving at the entrance control point of the expressway: the module vehicles with the same destination are combined and connected together to form a module vehicle marshaling, and passengers are guided to complete the transfer between module units according to the arrival city, and the unloading module units are disassembled to prepare for the departure task of the module vehicle marshaling, specifically:

[0071] (b.1) Arrival of modular vehicles at the highway entrance control point: The modular vehicle optimization grouping subsystem at the highway entrance and exit control point is used to number the modular vehicles according to the time when the modular vehicles arrive at the highway entrance control point within a unit time τ for N modular vehicles with the same destination in the same direction arriving at the same highway entrance control point. Figure 4 As shown in the first row, within this unit time τ, N = 5 module vehicles drive into the highway entrance control point of city A from different directions. The module vehicles are numbered in sequence according to the time when the module vehicles arrive at the highway entrance control point, and module vehicles G1, G2, G3, G4 and G5 are obtained. The passengers in module vehicle G2 go to city B, the passengers in module vehicles G3 and G5 go to city C, and the passengers in module vehicles G1 and G4 go to city D.

[0072] (b.2) De-grouping of the arrived modular vehicles: Each of the N modular vehicles is then de-grouped into a single modular unit. If there are multiple modular units in the modular vehicle, the corresponding de-grouping completion time is obtained according to the sequence of different modular units in the same modular vehicle. After de-grouping is completed, all modular units are numbered according to the de-grouping completion time of each modular unit. Figure 4As shown in the second row, the modular vehicle G1 is first disassembled. The modular vehicle G1 includes two modular units. According to the sequential positions of the two modular units in the modular vehicle G1, the disassembly completion time of the previous modular unit is earlier than the disassembly completion time of the next modular unit. Therefore, the previous modular unit is numbered as modular unit M1, and the next modular unit is numbered as modular unit M2. Then, the modular vehicle G2 is disassembled. The modular vehicle G2 also includes two modular units. According to the sequential positions of the two modular units in the modular vehicle G2, the previous modular unit is numbered as modular unit M2. The unpacking completion time of the block unit is earlier than the unpacking completion time of the subsequent module unit, so the previous module unit is numbered as module unit M3 and the subsequent module unit is numbered as module unit M4; then the module vehicle G3 is unpacked, and since there is only one module unit in the module vehicle G3, it is numbered as module unit M5; then the module vehicle G4 is unpacked, and since there is only one module unit in the module vehicle G4, it is numbered as module unit M6; then the module vehicle G5 is unpacked, and since there is only one module unit in the module vehicle G5, it is numbered as module unit M7.

[0073] (b.3) Modular vehicle reconnection: Then, according to the distance of the passenger's destination city in each modular unit and the number of the modular unit, all modular units are connected in sequence to form a modular vehicle group, and then all modular units in the modular vehicle group are renumbered in the order of front and back. Figure 4 As shown in the third row, after a modular vehicle formation is formed, all modular units in the modular vehicle formation are renumbered in a forward and backward order as N1, N2, N3, N4, N5, N6 and N7.

[0074] (b.4) Determine the number of departure module units: Determine the number of module units to each city based on the travel demand summary within the unit time τ. Figure 4 As shown in the fourth row, according to the summary of travel demand within unit time τ, the number of module units going to city D is determined to be 2, that is, the module units going to city D are module units N1 and N2; the number of module units going to city C is determined to be 1, that is, the module unit going to city C is module unit N3; the number of module units going to city B is determined to be 1, that is, the module unit going to city B is module unit N4.

[0075] (b.5) Passenger transfer within the train: According to the module unit number and the destination of each module unit, the carriage information is released to guide passengers to move to the corresponding module unit.

[0076] (b.6) Unloaded modular units: After the passengers have completed their movement, the unloaded modular units in the modular vehicle formation are separated from the modular vehicle formation to obtain a modular vehicle formation after unloading. The separated modular units are waiting to be assigned other pick-up and drop-off tasks. Figure 4 As shown in the fifth row, after the passengers complete the movement, the unloaded modular units in the modular vehicle formation are modular units N5, N6 and N7, and then the unloaded modular units N5, N6 and N7 are separated from the modular vehicle formation to obtain the modular vehicle formation after de-assembly, and the unloaded modular units N5, N6 and N7 are waiting to be assigned other pick-up tasks.

[0077] (b.7) Modular vehicle marshaling and departure: After the disassembly is completed, the modular vehicle marshaling is ready for departure and then drives to the destination.

[0078] The module vehicle optimization marshaling subsystem at the highway entrance and exit control point is used to combine with the module bus passenger pick-up and drop-off subsystem in the urban road to dispatch and reconnect the passengers in the module vehicle marshaling arriving at the highway exit control point according to the specific destination. After completing the mobile transfer of the passengers, the module unit is disassembled and the passenger is sent. Specifically,

[0079] (c.1) The module vehicle optimization grouping subsystem of the expressway entrance and exit control point is combined with the module bus passenger pick-up and drop-off subsystem in the urban road to group the modules of vehicles arriving at the expressway exit control point, such as Figure 5 As shown in the first row, modular vehicle group K arrives at the highway exit control point, and the number of modular units in modular vehicle group K is 5. First, determine the arrangement of modular units for picking up and dropping off passengers: according to the travel needs of all passengers in the modular vehicle group, summarize the city destinations, sort the city destinations from far to near, and number the city destinations in sequence, and then calculate the number of modular units going to each city destination according to the number of passengers in the modular vehicle group and the capacity of each modular unit. Figure 5 As shown in the second row, first determine the arrangement of the modular units for picking up and dropping off passengers: according to the travel needs of all passengers in the modular vehicle formation, statistics are summarized to obtain 5 city destinations, and the city destinations are sorted from far to near and numbered in sequence, numbered as city destinations D1, D2, D3, D4 and D5; then calculate the number of modular units going to each city destination according to the number of passengers in the modular vehicle formation and the capacity of each modular unit, and obtain the number of modular units going to the city destination D1 is 1, the number of modular units going to the city destination D2 is 2, the number of modular units going to the city destination D3 is 1, the number of modular units going to the city destination D4 is 1, and the number of modular units going to the city destination D5 is 1.

[0080] (c.2) If the sum of the number of modular units going to each destination in the city is greater than the sum of the number of modular units in the modular vehicle formation, the number of modular units that need to be dispatched is calculated, and the nearby idle modular units are dispatched to the highway exit control point in advance based on the shortest path principle; then the modular vehicle formation and the dispatched modular units are connected to obtain the connected modular vehicle formation, and then all the modular units in the connected modular vehicle formation are numbered in sequence;

[0081] If the sum of the numbers of modular units going to various destinations within the city is less than the sum of the numbers of modular units in the modular vehicle formation, all modular units in the modular vehicle formation are directly numbered in sequence.

[0082] like Figure 5 As shown in the second row, since the total number of modular units going to various destinations in the city is 6, and the number of modular units in the modular vehicle formation K is 5, the number of modular units that need to be dispatched is calculated to be 1=6-5. Based on the shortest path principle, one idle modular unit nearby is mobilized to the highway exit control point in advance. Figure 5 As shown in the third row, all the module units in the connected module vehicle formation are numbered as module units U1, U2, U3, U4, U5 and U6 in sequence.

[0083] (c.3) After completing the numbering of the module units, the carriage information is released according to the number of each module unit and the corresponding destination in the city to guide passengers to move to the corresponding module unit, such as Figure 5 As shown in the fourth row.

[0084] (c.4) All the modular units in the modular vehicle formation are then de-formed, and each modular unit transports passengers to a specific destination within the city, such as Figure 5 As shown in the fifth row.

[0085] The hub interchange control point module vehicle optimization marshaling subsystem is used to optimize the module vehicle marshaling after the module vehicle marshaling arrives at the hub interchange control point of the urban highway passing through, specifically:

[0086] Traffic flows from different directions are divided and merged at the highway hub interchange control point, and the highway hub interchange control point can implement the optimization and reorganization of multi-directional module vehicles. In the hub interchange control point module vehicle optimization marshaling subsystem, the traffic flow direction conversion is completed by the de-marshaling and re-marshaling of the module vehicle marshaling. Implementing the coordinated optimization marshaling of multi-directional module vehicles can realize the sharing of the basic module vehicle units of multi-directional traffic flow and improve the utilization rate of the module units. The schematic diagram of the highway hub interchange is as follows Figure 6 .

[0087] During the vehicle optimization process, the module units are all in the expressway network, the vehicle speed is relatively fast, and passengers on the vehicle are not allowed to transfer between module units at the hub control point. Therefore, the highway hub interchange control point only adjusts the position of the vehicle unit, that is, the module vehicle formation is optimized.

[0088] The modular vehicle group arrives at the highway hub interchange control point: Figure 7 As shown in Figure 1, within a unit time τ, modular vehicle groups from different cities arrive at the highway hub interconnection control point of any city. Passengers in modular vehicle groups from the same city may go to different cities, and passengers in modular vehicle groups from different cities may go to the same city;

[0089] (d.1) The urban highway hub interchange control point is divided into a front disassembly area and a reconnection area. When the modular vehicle marshaling from different cities arrives at the front disassembly area of ​​the highway hub interchange control point in the same city within a unit time τ, the hub interchange control point modular vehicle optimization marshaling subsystem disassembles the corresponding modular units in all modular vehicle marshaling according to the different cities that can be reached through the highway hub interchange control point, and ensures that the modular units going to the same city remain connected after disassembly;

[0090] (d.2) When modular vehicle groups from different cities arrive at the reconnection area of ​​the highway hub interchange control point in the same city within a unit time τ, the hub interchange control point modular vehicle optimization grouping subsystem will merge and reconnect different modular units going to the same city according to the order of arrival time and the distance from the corresponding city to form a modular vehicle group, and then advance the merged and reconnected different modular vehicle groups to the corresponding city.

[0091] Example 2

[0092] The following uses the intercity travel from Hangzhou to Shanghai as an example to explain the intercity modular bus system. Figure 8 As shown, it passes through Haining (Qitang Hub), Tongxiang (Tudian Hub), Jiaxing (Jiaxing Hub), Pinghu (Jiaxing Hub) and arrives in Shanghai.

[0093] The intercity bus system based on modular vehicles includes a modular bus passenger pick-up and drop-off subsystem in urban roads, a modular vehicle optimization grouping subsystem at expressway entrance and exit control points, and a modular vehicle optimization grouping subsystem at hub interchange control points.
