Embodiment Construction

[0030] The method for obtaining the driving condition information of the urban express bus comprises the following steps:

[0031] (1) Select a BRT vehicle and collect information from the BRT vehicle with a sampling frequency of 1s. The initial information collected includes the travel time as t i , the longitude is X i , with latitude Y i , the instantaneous velocity is V i ;

[0032] (2) Define the acceleration, deceleration, uniform speed and idling driving conditions during the driving process of the vehicle; the acceleration condition refers to the acceleration a>0.1m / s during the driving process of the vehicle 2 ;Deceleration condition refers to the vehicle acceleration a2 ;Constant speed condition refers to -0.1m / s when the vehicle is running 2 ≤a≤0.1m / s 2 ;Idling condition means that the engine of the vehicle is in working condition but the driving speed is 0;

[0033] (3) Transform the initial information, and define the instantaneous velocity after processing ...

Abstract

The invention relates to a method for acquiring the driving condition information of an urban bus rapid transit, which comprises the following steps: firstly, selecting a BRT (Bus Rapid Transit) vehicle and carrying out information acquisition to the BRT vehicle through the sampling frequency of 1s, wherein the acquired initial information comprises the driving time ti, the longitude Xi, the latitude Yi and the instantaneous velocity Vi; secondly, defining the acceleration, deceleration, constant speed and idle speed driving conditions in the driving process of the vehicle; thirdly, converting the initial information; and fourthly, analyzing the vehicle information. The method has the beneficial effects that the working condition information of the vehicle can be accurately or precisely obtained, and more working condition information of the vehicle can be obtained to be convenient for understanding the working conditions of the vehicle.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a method for acquiring driving condition information of urban express buses. Background technique [0002] In order to effectively alleviate urban traffic congestion and motor vehicle exhaust pollution, save energy and reduce emissions, more and more cities in China are actively implementing the bus priority strategy in their transportation policies and vigorously promoting Bus Rapid Transit (BRT). BRT is a new type of public passenger transport system between rapid rail transit and conventional public transport. Intelligent transportation and operation management (such as signal priority system), open up bus-only roads and build new bus stations, realize rail transit operation services, and a unique urban passenger transportation system that reaches the service level of light rail. [0003] In China, the total mileage and total running time of the starting ...
