System and method for automatically adjusting traffic light
First Claim
1. A method comprising:
- obtaining personal data relative to a pedestrian crossing an intersection, said personal data including at least walking speed of said pedestrian;
obtaining current speed of at least one vehicle approaching the intersection;
processing said personal data and the current speed of said at least one vehicle to create at least one cross walk indicator; and
adjusting a traffic light according to the value of said at least one cross walk indicator.

Abstract
A system, program product and method for automatically adjusting the traffic light of a traffic light controlled intersection. Personal data relative to a pedestrian cross walking the intersection, including walking speed, and the current speed of a vehicle approaching the intersection are simultaneously acquired. Both the personal data and the vehicle current speed are processed to generate cross walk control signals, such as indicators of risk of collision between vehicle and pedestrian. Where the risk warrants action, the “stop” condition of the traffic light is enable to warn the vehicle to stop. Traffic control signals are also generated to control the duration of the “walk” condition for slow moving pedestrians.

15. A computer program product for controlling a traffic light, said computer program product comprising:
-
a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising; a first program instruction to access personal data in said relative to a pedestrian crossing an intersection, said personal data including at least walking speed of said pedestrian; a second program instruction to access the current speed in said of at least one vehicle approaching said intersection; a third program instruction to process said personal data and said current speed of said at least one vehicle to generate traffic control decisions and; a fourth program instruction acting to generate traffic light control instructions according to said traffic control decisions. - View Dependent Claims (16, 17, 18, 19, 20)
