Problems solved by technology

[0002] At this stage, the low bus fare has made a great contribution to improving the attractiveness of public transportation, but the actual operation problems such as low bus punctuality and poor service level have caused the public transportation vehicles to fail to meet the needs of passengers to reach their destinations on time, which has reduced to some extent. bus attraction

Embodiment Construction

[0017] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0018] The present invention provides a kind of intersection signal light control method based on bus stopping time, such as figure 1 shown, including the following steps:

[0019] Establish a bus station stop time estimation model;

[0020] Get the number of pre-get-off passengers at each bus stop and the number of passengers who want to get on the bus at each bus stop, and substitute it into the bus stop time estimation model to estimate the stop time of each bus at the next stop;

[0021] Obtain the bus queuing sequence at the intersection, and calculate the time required for all buses at the intersection to enter the station according to the bus queuing sequence and the estimated stopping time of each bus at the next stop;

[0022] Obtain the intersection signal timing scheme, find the green light duration of the next traffic light ...

Abstract

The invention provides an intersection signal lamp control method based on bus dwell time, including the following steps: establishing a bus stop dwell time estimation model; acquiring the number of passengers getting off and the number of passengers getting on at next stop for each bus, and substituting the number of passengers getting off and the number of passengers getting on into the bus stopdwell time estimation model to estimate the dwell time of each bus at next stop; calculating the number of buses queuing at an intersection and a queuing sequence of the buses, and estimating the time needed for all the buses at the intersection to enter the stop; and obtaining the signal timing scheme of the intersection, querying for the green time of next traffic light cycle at the intersection, and making a judgment: if the time needed for all the buses at the intersection to enter the stop is longer than the green time of next traffic light cycle, taking the time needed for all the busesat the intersection to enter the stop as the green time of next traffic light cycle; otherwise, continuing to execute the original timing scheme of the intersection.

Description

technical field [0001] The invention relates to a method for controlling a signal lamp at an intersection, in particular to a method for controlling a signal lamp at an intersection based on the stopping time of a bus. Background technique [0002] At this stage, the low bus fare has made a great contribution to improving the attractiveness of public transportation, but the actual operation problems such as low bus punctuality and poor service level have caused the public transportation vehicles to fail to meet the needs of passengers to reach their destinations on time, which has reduced to some extent. bus attraction. Therefore, under certain conditions of urban road resources and public transportation capacity allocation, it is imperative to alleviate road traffic congestion by continuously improving the operation status to enhance the attractiveness of public transportation. [0003] In order to solve the above existing problems, people have been seeking an ideal techni...
