US 2026/0279197 A1 · METHOD OF CONTROLLING TRAFFIC FLOW AND DETECTING TRAFFIC RULE VIOLATIONS AND SYSTEM PERFORMING THE SAME

Abstract

A method controls traffic at an intersection having three or more branches. The method comprising the steps of: capturing image data by a plurality of camera units positioned at the intersection; sending the image data to a control unit; determining from the image data a plurality of variables; and based on the plurality of variables, determining speed limits, and setting orders and durations of lights of a plurality of traffic lights positioned at the intersection. A system performs the method. Advantages of instant disclosure include adjustment of on-duration of a light using weather condition; reporting vehicles violating traffic rules to police centers; blurring license plates of surrounding vehicles; and smoother traffic flows.

Dependent claims

A method for controlling traffic at an intersection comprising three or more branches, the method comprising the steps of:

capturing by a plurality of camera units positioned at the intersection, image data of each incoming direction of the three or more branches;
sending the image data of each incoming direction to a control unit;
determining from the image data of each incoming direction, a respective number of a plurality of vehicles in each incoming direction of the three or more branches within a predetermined distance and a respective speed of each of the plurality of vehicles;
determining based at least in part on the respective number of the plurality of vehicles and the respective speed, a plurality of cycles of switching-on timing and on-duration of each light of a plurality of traffic lights positioned at the intersection;
and
adjusting the on-duration of each light of the plurality of traffic lights using a weather condition.

3 more elements

A system comprising

a plurality of camera units positioned at an intersection comprising three or more branches;
a plurality of traffic lights positioned at the intersection;
and
a control unit;
wherein the system is configured to perform functions to:
capture by the plurality of camera units, image data of each incoming direction of the three or more branches;
send the image data of each incoming direction to the control unit;
determine from the image data of each incoming direction, a respective number of a plurality of vehicles in each incoming direction of the three or more branches within a predetermined distance and a respective speed of each of the plurality of vehicles;
determine based at least in part on the respective number of the plurality of vehicles and the respective speed, a plurality of cycles of switching-on timing and on-duration of each light of the plurality of traffic lights;
and
adjust the on-duration of each light of the plurality of traffic lights using a weather condition.

8 more elements

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a control unit, cause the control unit to perform the steps of:

instructing a plurality of camera units positioned at an intersection comprising three or more branches to capture image data of each incoming direction of the three or more branches;
sending the image data of each incoming direction to the control unit;
determining from the image data of each incoming direction, a respective number of a plurality of vehicles in each incoming direction of the three or more branches within a predetermined distance and a respective speed of each of the plurality of vehicles;
determining based at least in part on the respective number of the plurality of vehicles and the respective speed, a plurality of cycles of switching-on timing and on-duration of each light of a plurality of traffic lights positioned at the intersection;
and
adjusting the on-duration of each light of the plurality of traffic lights using a weather condition.
