Embodiment Construction

[0020] method embodiment

[0021] The bus arrival time estimation method of the present invention is to divide the bus operation line into several sections, determine the operation time of each section according to the vehicle operating speed model and each factor data that affects the vehicle operating speed, thereby realizing the bus arrival time estimate. Among them, the data of various factors affecting the running speed of the vehicle are obtained by the on-board unit and the roadside unit, such as figure 1 As shown, the on-board unit (OBU) is installed on the vehicle, and the roadside unit (RSU) is installed on both sides of the road. The on-board unit can realize vehicle-to-vehicle communication through V2X, radio frequency identification (RFID) or mobile communication network (4G, 5G). And the communication between vehicles and traffic facilities, to obtain road congestion, the density of people and traffic, the signal light phase information to the next stop, and sur...

Abstract

The invention relates to a bus arrival time estimation method and device, and belongs to the technical field of intelligent traffic. The method comprises the following steps of segmenting a bus running line, determining the running speed of each section of line according to each section of factor data influencing the bus running speed by using a vehicle running speed model, dividing the running speed of the corresponding section by a segmentation distance to obtain the running time of each section, accumulating to obtain the inter-station running time, and determining the estimated arrival time of each station. Therefore, the arrival time of the bus can be estimated. According to the invention, the condition that the road conditions on each section of the line are different and the types of factors influencing the running speed of the vehicle are changed is considered, the arrival time is estimated by calculating the running time of each section, the prediction process accords with with the actual road conditions, and the obtained estimated time is more accurate.

Description

technical field [0001] The invention relates to a method and device for estimating the arrival time of a bus, belonging to the technical field of intelligent transportation. Background technique [0002] At present, the number of vehicles continues to increase, resulting in traffic congestion, complex vehicle application scenarios, traffic safety, traffic efficiency and vehicle energy consumption and other issues are becoming more and more serious. At present, the arrival time of vehicles provided on bus stop signs and collection apps is mostly based on the distance between the vehicle position and the platform divided by the average vehicle speed (vehicle speed converted from GPS speed and wheel speed). However, due to the complexity of the traffic environment on urban roads, severe congestion, and changing road traffic conditions, especially during rush hour, the traffic density of vehicles is high, and the actual arrival time of buses usually deviates too much from the es...
