Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0053] A method for guiding and controlling the speed of a bus entering a station, such as image 3 shown, including:

[0054] Step S1: Determine whether the road section is overtraveled, if yes, execute step S2, otherwise, execute step S4;

[0055]Step S2: Judging whether the estimated arrival time of the current vehicle entering the station to be entered is the earliest among all vehicles, if yes, then execute step S7, otherwise, execute step S3;

[0056] Step S3: sort the estimated arrival time of each vehicle entering the station in order, obtain the estimated arrival time of th...

Abstract

The invention relates to a bus stop arrival speed guiding controlling method of a bus and a system thereof. The bus stop arrival speed guiding controlling method of the bus comprises the steps that S1, whether the road segment is in overtaking or not is judged, if so, S2 is performed; otherwise, S4 is performed; S2, whether a current vehicle is the earliest to arrive at a station or not, if so, S7is performed; otherwise, S3 is performed; S3, the estimated arrival time of a previous vehicle in the time queue is acquired in real time as the threshold time, and S6 is performed; S4, whether a vehicle which needs to enter the same station exists in front or not is judged, if so, S5 is performed; otherwise, S7 is performed; S5, the estimated arrival time of the nearest vehicle in front is acquired in real time as the threshold time, and S6 is performed; S6, the current vehicle speed is guided and controlled based on the threshold time, and the estimated arrival time is updated and sent to the outside; and S7, according to station berth information and the current vehicle, the speed of the current vehicle is guided and controlled, and the estimated arrival time is updated and sent to theoutside. Compared with the prior art, the clustering phenomenon can be avoided.

Description

technical field [0001] The invention relates to the field of traffic information engineering and control, in particular to a method and system for guiding and controlling the speed of a bus entering a station. Background technique [0002] As a green and sustainable way of travel, public transportation is widely advocated in big cities. In order to improve citizens' satisfaction, the number of urban buses has been increasing year by year, and the number of buses in operation is huge and the operation density is very high. But on the other hand, due to the unreasonable planning of a single bus station or the limited berths, if a large number of buses arrive one after another in a short period of time, it will cause a large number of buses to cluster (that is, the congestion of buses at the station). Passing through, if the management is not good, it will easily cause road traffic bottlenecks and safety problems. [0003] In the prior art, there is no mature bus cluster phen...
