Protecting Road Transport from Disasters
In recent years, we have witnessed the damage caused by a range of natural disasters including typhoons and torrential rain.
Problems such as the malfunction of road traffic signal controllers due to submersion in floods, and the loss of power to road traffic signal units due to electricity outages, can lead to traffic accidents.
For road traffic signal controllers especially, malfunctions mean that traffic cannot be controlled until the equipment is replaced.
In places where the road dips and cannot be seen clearly, such as under elevated roads and overpasses, drivers sometimes drive their vehicles into water, unaware that the road ahead is flooded.
Kyosan provides a full range of products to protect road traffic signal systems from these disasters, and mitigate the risk of traffic accidents due to disasters.
Waterproof Road Traffic Signal Controllers
A regular road traffic signal controller can withstand rain without malfunctioning, but if submerged in water during a flood, then the equipment within the casing will get wet, leading to malfunction and rendering it unusable.
Waterproof road traffic signal controllers feature a more waterproof casing, preventing malfunction of the road traffic signal controller even when the road is submerged in water due to river flooding or other cause.
Road traffic can be controlled as soon as the flooding subsides.
Disaster Prevention-type Road Traffic Signal Controllers
These are traffic signal controllers equipped with a special function that displays a red light to prevent cars approaching the city center in the event of a major earthquake.
Additional Power Supply Devices for Waterproof Road Traffic Signals
A regular additional power supply device will malfunction if submerged in water during a flood, rendering it unusable.
This product encases the additional power supply device in a waterproof covering, protecting the device in a flood. Once waters have receded, the device can supply power to road traffic signals for a period of time in the event of a power outage.
Additional Power Supply Devices for Road Traffic Signals
These additional power supply devices for road traffic signals contain lithium ion batteries, maintaining power to road traffic signal units in the case of electricity outages.
The devices do not use generators, eliminating any environmental impact from exhaust gas, as well as being free from noise and vibration.
Additional Power Supply Devices for Road Traffic Signals II
These additional power supply devices for road traffic signals, maintaining power to road traffic signal units during electricity outages, feature indicator lights that show the electrical supply status.
This allows observers such as police cars on patrol to easily check the electrical supply status from the back of the device, which faces onto the road.
Road Flooding Warning Display System
This system detects the water level during floods in places where the road dips, such as under elevated roads and overpasses or in similar locations, and warns passing traffic by displaying a flooding sign board and revolving warning light.
This prevents traffic from becoming stuck on flooded roads due to torrential rain or other flooding, and leading to traffic accidents.
