Embodiment Construction

[0067] Provide the specific embodiment of the present invention below, the meaning of some character representations involved in the present embodiment is as follows:

[0068] V n (n is a natural number): speed limit value, where n is a different value representing different weather and road conditions;

[0069] V i (i is a natural number greater than or equal to 1 and less than or equal to n): the speed limit value under the current weather and road conditions;

[0070] (x nj ,y nj ): Indicates that the speed limit value is V n, the longitude and latitude coordinate information of the reference position of the BRT vehicle at the jth second, where j=0,1,2,3...;

[0071] t nj : Indicates that the speed limit value is V n , the travel time of the BRT vehicle, that is, the jth second;

[0072] T nj : Indicates that the speed limit value is V n , the moment when the BRT vehicle arrives at the jth reference position;

[0073] (x D ,y D ): Indicates the latitude and lon...

Abstract

The invention discloses a system and method for enabling a bus rapid transit dispatch to be corrected to seconds at the time of a sudden change of weather or a road condition. When people dispatch a bus rapid transit vehicle, a rapid public traffic vehicle is used for being driven one time in advance at the speed under various weather conditions along a bus rapid transit line, wherein the bus rapid transit vehicle is provided with a vehicle-mounted GPS positioning unit. Position information of the vehicle-mounted GPS positioning unit at every second and at various speeds serves as reference positions in running schedules. In the actual driving process of the bus rapid transit vehicle, a GPS positioning module arranged on the bus rapid transit vehicle is used for obtaining actual position information of the bus rapid transit vehicle at the moment in a real-time mode. The actual position information is directly compared with reference position information. Through simultaneous starting of the running schedules under various weather conditions, the running schedule meeting the speed requirement under the current weather condition can be started within a second when the weather condition changes, and the system and method continue to meet the running dispatch precision which is corrected to seconds.

Description

technical field [0001] The invention relates to the field of rapid transit dispatching, in particular to a rapid transit dispatching system and method capable of being accurate to seconds when the weather or road conditions suddenly change. Background technique [0002] Urban road traffic is the "blood vessel" of the city, and making it smooth is the guarantee for the sustainable development of the city. At present, the supply of urban road traffic is far from meeting the traffic demand, resulting in urban road traffic congestion. The causes of urban traffic congestion are multi-faceted. How to improve the efficiency of public transportation to meet traffic demand and alleviate traffic congestion is one of the main issues that traffic management decision-makers care about. [0003] Letting people prefer public transportation is one of the main means for traffic management decision makers to improve the efficiency of urban road traffic. To this end, many cities have success...
