Embodiment Construction

[0047] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0048] The basic idea of ​​the present invention is: in the real-time driving control process of the networked public transport, comprehensively use vehicle GPS positioning, intersection vehicle identification, platform vehicle identification information, and realize the calculation of vehicle motion information on the basis of division of driving route sections, By giving a calculation method of the ideal minimum interval, and using the ideal minimum interval to define the grade quantification standard of smooth, saturated unimpeded, congested, severely congested and extremely congested road usage conditions. Then detect the average travel time and average driving speed of vehicles in each divided section, and determine the location of the vehicle section. In the case of prediction or road congestion, use...

Abstract

The invention discloses a public transport travelling control method by combining signal control with positioning monitoring. Aiming at a rapid public bus line, vehicle GPS positioning, intersection vehicle recognizing and platform vehicle recognizing information are comprehensively utilized in the method, and based on the division of a driving direction section, the calculation of vehicle motioninformation is realized. The invention provides an ideal minimum separation calculating method and a grade quantization dividing standard of smooth, saturated smooth, crowd, seriously crowd and extremely crowd road use conditions by using the ideal minimum separation. Under the condition of predicting or generating road crowd, a driving control method by combining the signal control with the vehicle fixed monitoring is provided, the vehicle space can be reasonably regulated, and conditions of bunching and unreasonable large spacing are effectively reduced. The method is simple and easy to realize and can solve the problem of unreasonable spacing between vehicles in the rapid public bus line, thereby achieving the purpose of improving the transportation service level of the public bus line.

Description

technical field [0001] The invention relates to traffic control technology, in particular to a method for controlling traffic of public transport vehicles combining signal control and positioning monitoring. Background technique [0002] In order to solve the contradiction between the increasing number of vehicles, passengers, pedestrians and limited traffic resources in the city, giving priority to the development of public transport has become an important means to solve urban traffic problems. To develop public transportation, it is first necessary to improve the utilization efficiency of transportation facilities and improve the service ability of transportation. Therefore, the traffic control of public transport vehicles, which combines signal control and positioning monitoring, has become one of the main methods. [0003] The existing Bus Rapid Transit (BRT) has a good hardware foundation and good road priority conditions, and can provide fast transportation services. ...
