Abstract: In each of delineator streetlights of a low-altitude, low-power installable smart streetlight system, a lighting unit is formed on a roadside, and a reflection panel is formed on an opposite-side of a direction of traffic. A low-power Bluetooth antenna relays control signals between nearby the delineator streetlights, and an alert panel is equipped on the reflection panel. A first sensor detects vehicles on roads and outputs a detection signal, and second sensors detect a wild animal and output a detection signal. A control unit controls the lighting unit to turn on when a car detection signal is inputted from the sensor unit, successively transmits the control signal to nearby the delineator streetlights, controls the alert panel to flash when a wild animal detection signal is inputted from the sensor unit, and transmits a control signal of flashing the alert panel to nearby the delineator streetlights.

Abstract: Proposed is a smart guardrail capable of absorbing a shock induced when a vehicle collides with the guardrail to protect an occupant against the shock and of in real time performing monitoring and remote control to prevent a subsequent traffic accident. The smart guardrail, including a support fixedly installed at an equal distance at a center or an edge of a road, and a guardrail plate fixedly coupled to one or both sides of the support, further includes: a shock absorption member absorbing and thus reducing a shock induced when a vehicle collides with the guardrail; and a terminal configured to detect an external shock, an appearance of a wild animal on the road, and transmit a warning signal to an adjacent terminal positioned in a direction opposite to a traveling direction of the vehicle and to terminals positioned in succession behind the adjacent terminal.

Abstract: The present invention relates generally to a low-altitude, low-power installable smart streetlight system thereby, more particularly, a system that allows safe driving by alerting drivers and that saves power consumption by successively switching on or flickering the delineator streetlights, which are installed in regular intervals at the same height as vehicles, in relay.

Abstract: The present invention relates to an emergency warning system includes a low energy Bluetooth module, which is equipped in the delineators, that transmits a beacon signal which includes an emergency warning signal, to nearby delineators in relay and sends emergency warning signals as push notifications to nearby drivers' smartphone S1, an internet of things communication module, which is equipped in the first delineator (top repeater) and the 1 many delineators installed in regular intervals on medians or guardrails, with individually unique IDs, grouped into zones and having reflective panels and LED lights, an internet of things communication module, which is equipped in the first delineator (top repeater) and the last delineator (bottom repeater) within the zone in the direction of driving, a bottom repeater that collects emergency warning information and transmits the information to the central control server through the internet of things communication module, and a central control server.

Abstract: The present invention relates to an emergency alert and warning apparatus and, more particularly, to a road emergency alert and warning apparatus which is installed on a median strip or a guide rail of an expressway or the like to alert a driver of a rear vehicle of an emergency situation when a traffic accident occurs during nighttime driving, thereby preventing an additional secondary accident.
