Problems solved by technology

Similarly, the premise of bus priority for trunk line coordination needs to be based on the sub-area division of bus arterial coordination. However, the current traffic sub-area division is basically aimed at the control sub-area of ​​social vehicles, and there are few studies on the coordination of bus arterial lines.

Embodiment Construction

[0025] In order to obtain the specific time when the dedicated lane bus arrives at the downstream intersection, it is necessary to analyze and judge the travel time of the road section. Combining the driving characteristics of dedicated lane buses and social vehicles, the difference in travel time between the two is mainly different from the fact that public buses include parking time and social vehicles do not need to stop. The specific model analysis is as follows:

[0026] Such as figure 1 As shown, by analyzing the number n of each vehicle and the arrival time t of road section i iarr , Arrival time t iarrs , Departure time t idep , Arriving at the stop line of the downstream intersection at time t iarn

[0027]

[0028] Where t itp Is the travel time in front of the road section i, t itb It is the post-station travel time of section i.

[0029] Through statistics of the travel time before the station and the travel time after the station of the shift n, the average travel...

Abstract

The invention provides a partitioning method for bus lane trunk coordination. First, the one-time pass rate of buses passing through a downstream intersection in a period is calculated, and a one-time pass rate matrix is established; Then, Euclidean distance calculation is carried out on the one-time pass rate matrix to get a Euclidean distance matrix thereof; next, the Euclidean distance matrix is classified through a k-means clustering algorithm, and the intersection is partitioned according to the classification result; and finally, the phase difference of partitions is adjusted according to the partitioning result.

Description

Technical field [0001] The invention relates to a method for dividing a dedicated lane bus trunk line coordination sub-area, in particular to a clustering and partitioning method based on a one-time pass rate of dedicated lane buses. Background technique [0002] The division of traffic control sub-zones is based on the study of the uneven spatial distribution of road network supply and demand, in order to reduce the complexity of management and control, and improve traffic efficiency and system stability. As one of the important contents of modern traffic engineering research, there are many results and applications in the research of urban traffic planning and control. Compared with social transportation, public transportation vehicles are subject to multiple impacts such as operation scheduling, signal control, and public transportation stations. Therefore, public transportation priority will inevitably put forward new requirements for the division of control sub-areas. Simil...
