US 2015/0084791 A1 · APPARATUS AND METHOD FOR MANAGING SAFETY OF PEDESTRIAN AT CROSSWALK

Abstract

Disclosed herein are an apparatus and method for managing safety of a pedestrian at a crosswalk, which determine the location of a pedestrian in a crosswalk area, and then selectively provide a pedestrian signal extension service, an approaching vehicle notification service, and a pedestrian danger notification service. A presented apparatus includes a monitoring unit for monitoring a crosswalk area in which a pedestrian waits or crosses a street. A detection unit detects whether a pedestrian is present in the crosswalk area, based on information output from the monitoring unit. A location determination unit determines a location of the pedestrian detected by the detection unit. A safety determination unit determines whether the pedestrian is safe, based on the location of the pedestrian and a state of a pedestrian signal. An information provision unit outputs danger notification information based on a safety/danger determination signal output from the safety determination unit.

Dependent claims

An apparatus for managing safety of a pedestrian at a crosswalk, comprising:

a monitoring unit for monitoring a crosswalk area in which a pedestrian waits or crosses a street;
a detection unit for detecting whether a pedestrian is present in the crosswalk area, based on information output from the monitoring unit;
a location determination unit for determining a location of the pedestrian detected by the detection unit;
a safety determination unit for determining whether the pedestrian is safe, based on the location of the pedestrian determined by the location determination unit and a state of a pedestrian signal output from a signal controller, the safety determination unit determining whether the pedestrian is safe by calculating a safe crossing time needed for the pedestrian to safely cross a street at the crosswalk from the location of the pedestrian and by comparing the safe crossing time with a remaining pedestrian green time output from the signal controller;
and
an information provision unit for outputting danger notification information based on a safety/danger determination signal output from the safety determination unit.

A method for managing safety of a pedestrian at a crosswalk, comprising:

monitoring, by a monitoring unit, a crosswalk area in which a pedestrian waits or crosses a street;
detecting, by a detection unit, whether a pedestrian is present in the crosswalk area, based on information obtained at monitoring;
determining, by a location determination unit, a location of the pedestrian detected at detecting whether the pedestrian is present;
determining, by a safety determination unit, whether the pedestrian is safe, based on the location of the pedestrian determined at determining the location and a state of a pedestrian signal output from a signal controller, wherein determining whether the pedestrian is safe is performed by calculating a safe crossing time needed for the pedestrian to safely cross a street at the crosswalk from the location of the pedestrian and by comparing the safe crossing time with a remaining pedestrian green time output from the signal controller;
and
outputting, by an information provision unit, danger notification information based on a safety/danger determination signal output at determining whether the pedestrian is safe.
