Embodiment Construction

[0026] Referring to the attached picture:

[0027] The bus departure control method includes:

[0028] 1. Use satellite positioning equipment to collect the time T of the bus arrival ij , calculate the delay time difference ΔT against the timetable ij =|t ij -T ij |, establish ΔT ij The set R of . Among them, T ij Indicates the actual time when the i-th bus arrives at the j-th stop, t ij Indicates the time when the i-th bus specified in the bus schedule arrives at the j-th stop, ΔT ij Indicates the delay time difference of the i-th bus at the j-th stop.

[0029] 2. Statistically analyze the data set R, and divide the bus departure time into time slots according to the degree of road congestion.

[0030] 3. Establish the departure interval model, and re-divide the departure interval within the time period.

[0031] 4. The time information T collected in step 1 ij Substitute into the model to calculate the departure interval to make a departure plan.

[0032] Wherein...

Abstract

Disclosed is a bus departure control method. The method comprises: by use of a satellite positioning device, acquiring time Tij when a bus arrives at a station, according to a time table, calculating a delay time table delta Tij=|tij-Tij|, and establishing a set R of delta Tij, wherein Tij indicates the time when an i-th bus arrives at an j-th station, tij indicates the time, prescribed in a bus driving time table, when the i-th bus arrives at the j-th station, and delta Tij indicates a delay time difference when the i-th bus is at the j-th station; counting and analyzing the data set R, and according to the congestion degree of a road, performing period division on bus departure time; establishing a departure interval model, and redividing departure intervals in time periods; and substituting the time information Tij acquired in step one into the model for calculating the departure intervals so as to make a departure plan.

Description

technical field [0001] The invention belongs to the field of traffic control, and in particular relates to a method for optimizing the departure interval of buses to improve the punctuality rate. Background technique [0002] The public transport system is a social service system for the public, and its service quality has attracted more and more attention. Along with the quickening of people's rhythm of life, it is of great significance to ensure the punctual rate of buses. However, the proportion of existing urban lines that can guarantee the punctual arrival of buses is very small, which will not only destroy the normal traffic order but also affect the travel of passengers. [0003] At present, the countermeasures to improve the punctuality rate of public transport mainly include public transport right of way priority, traffic signal priority and establishment of BRT system. However, according to the transportation department, traffic congestion is the main reason affe...
