A bottleneck detection method for bus-only lanes based on bus-mounted GPS data

Abstract

The invention discloses a bus lane passage bottleneck detection method based on bus-mounted GPS (global positioning system) data, comprising the steps of 1, acquiring statistics for coordinates and time information in GPS data of buses running on a same bus lane within a period of time T to obtain positional and speed information of the buses; 2, dividing the bus lane into n sections; 3, dividing a day into m peak periods, and dividing each peak period into p periods of time; 4, dividing the n sections into suspected bottleneck sections and non-bottleneck sections according to the speed information of the buses at the different sections; 5, removing signal crossings and bus stop sections from the suspected bottleneck sections to obtain the passage bottleneck sections for the bus lanes. The method has the advantages that bus-mounted GPS data are made effective use to find out passage bottlenecks for bus lanes, the bus-mounted GPS data are easy and reliable to acquire, required bus-mounted GPS equipment are devices already fitted to existing buses, extra expense is not required, and the method is highly implementable.

Description

technical field [0001] The invention belongs to the field of traffic planning, and in particular relates to a method for detecting bottlenecks of roads dedicated to public transportation. Background technique [0002] In recent years, with the rapid development of my country's economic level and the acceleration of urbanization, the number of motor vehicles has increased sharply, resulting in an imbalance between traffic demand and traffic supply, resulting in problems such as traffic congestion, environmental pollution, and traffic safety. Urban road traffic Can no longer meet the needs of social and economic development. [0003] Public transportation occupies less road space and has a large passenger capacity. The road resource utilization efficiency of public transportation during peak hours is 30 times that of cars, 10 times that of motorcycles, and 4 times that of bicycles. Alleviating urban traffic problems by giving priority to the development of public transport has...

AI Technical Summary

Problems solved by technology

[0004] However, in practice, buses are often disturbed during operation, such as pedestrians crossing the street on crosswalks, cars entering and exiting at entrances and exits, cars illegally occupying bus lanes, and the inconvenience caused by merging and changing lanes of bus lanes. Continuous etc.

These problems have seriously affected the operating efficiency of buses, resulting in low punctuality and poor safety of buses.
