Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of driverless buses, and in particular to a method for analyzing passenger behavior at a digital platform and pushing personalized services. Background Art
[0002] With the rapid development of technology, intelligent buses, as an important part of intelligent transportation, remain a major part of urban transportation. However, there are still many deficiencies in the current bus system in terms of passenger services. Traditional bus stops have a single function and mainly provide simple route information displays for passengers. They cannot effectively analyze passenger behavior and are also difficult to provide personalized services according to individual passenger needs.
[0003] Therefore, under the existing bus operation mode, buses cannot accurately grasp information such as passengers' travel habits and waiting preferences. For example, behavioral characteristics such as passengers' waiting time at the stop, whether they carry luggage, and whether they have accompanying persons are not fully utilized. This leads to a lack of pertinence in bus operation scheduling, and buses cannot reasonably arrange vehicle resources according to actual passenger needs, thus affecting the passenger travel experience and reducing the overall operation efficiency of the bus system.
[0004] At the same time, due to the lack of a personalized service push mechanism, passengers cannot obtain information related to their own needs when taking the bus, such as surrounding scene recommendations, real-time traffic condition reminders, bus transfer suggestions, etc. This makes the bus system have a large gap from modern passengers' expectations in terms of service diversity and user stickiness.
[0005] In the prior art, Chinese Patent (Application No.: 202411972313.3, Publication No.: CN 119848349A) discloses a method and system for processing data of an intelligent bus waiting pavilion based on digital analysis, including collecting seat usage information and air-conditioning usage status in the target vehicle, calculating temperature distribution information and crowding degree information of different seats and sending them to all waiting pavilions for data sharing; receiving a request instruction from the target passenger, identifying the target passenger's historical riding records and current riding demand information, predicting riding preference behavior and the expected distance from the desired seat to the disembarkation point; constructing a seat recommendation model based on the temperature distribution information, crowding degree information, riding preference behavior and expected distance, generating a target seat for recommendation, and when the target passenger determines to use the target seat, updating the data and synchronizing it to all waiting pavilions to continue recommending seats for the next passenger. In this solution, the data accuracy depends on devices: the collection of data such as seat usage information and air-conditioning usage status depends on the accuracy of in-vehicle devices. If the devices malfunction or have insufficient accuracy, it may lead to incorrect calculation of temperature distribution and crowding degree information, thereby affecting the accuracy of seat recommendation.
[0006] Limitations of passenger behavior prediction: Although passenger preference behaviors are predicted based on historical riding records and current demands, passenger travel demands may change temporarily due to special circumstances. Predictions based only on partial historical and current information are difficult to cover all complex and changing actual situations, resulting in deviations between the recommended seats and the actual demands of passengers. System complexity and maintenance costs: It involves complex operations such as data interaction between vehicles and multiple waiting pavilions, various information analyses, and model construction. The construction and maintenance of the system require high costs, including equipment maintenance, data management, and investment in technical personnel, etc.
[0007] In the prior art, a platform passenger detection system and method for a driverless bus are disclosed in a Chinese patent (application number: 201810938571.8, publication number: CN 108830264A), which includes an on-vehicle computing terminal, an external front camera of the vehicle, an external rear camera of the vehicle, an external left camera of the vehicle, an external right camera of the vehicle, a display, a GPS global positioning module, a 4G network communication module, and a PC remote monitoring center; the on-vehicle computing terminal includes an ARM controller, a DSP image stitching module, a DSP image detection module, a GPU module, and a CAN communication module; the DSP image stitching module is connected to the ARM controller and is used for real-time processing of the videos of the 4 external cameras of the vehicle and stitching them into a panoramic video; the DSP image detection module is connected to the ARM controller and is used for real-time processing of the video of the front camera inside the vehicle and identifying and detecting the passengers on the platform of the driverless bus so as to automatically park the vehicle; the 4G network communication module is connected to the ARM controller; the 4 external camera modules are used for collecting real-time videos around the vehicle. The system of this solution highly depends on the data collected by the external cameras of the vehicle. In case of bad weather (such as heavy rain, heavy snow, thick fog, etc.), the field of view of the cameras may be affected, resulting in unclear image acquisition, which in turn affects the accuracy of passenger detection and the normal operation of the system. The 4G network communication module is used to transmit information to the PC remote monitoring center. When the network signal is unstable or there is network congestion, data transmission delay may occur, affecting the real-time nature of remote monitoring and the timely control of the vehicle. Summary of the Invention
