Field of the Invention
The present invention particularly relates to a real time alert system on blind bends using WIM sensor & LoRa.
Background of the Invention
This invention relates to a real time warning system at points where there are blind bends in roads with hilly and rolling terrain to warn the driver of a vehicle approaching from the opposite direction so that they can maintain their speed, stay in their respective lanes, and avoid to attempt overtaking action which will escape any chance of collision. WIM Sensor is placed at the top most layer of pavement is connected with a displaying unit placed at the edge of road, via LoRa modem. When any vehicle from any side passes the WIM sensor, an alert signal will be displayed in the opposite direction of LED Display. This whole invention will help in reducing the accident changes at those risky blind bends. Displaying unit is also capable of displaying other information like weather forecast of the area, visibility of the area, temperature and also displays the distance of nearby locations by gathering data from the cloud server.

SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention.
This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
Mountain roads or rolling terrain have huge amount of bends. There are certain blind bends where there is a very high risk of collision-related incidents. So, a real time monitoring and alert system is proposed which will help in reducing any chance of collision incidents at those positions. A system is proposed which will display the alert signal over the LED Display placed on the side of the road, if any vehicle is approaching from any direction. Drivers can reduce their speed, stay in their respective lanes, and refrain from attempting to pass another vehicle after spotting the signal. Before a few meters of bend, WIM sensor is installed on the top layer of the pavement in both directions. When a vehicle passes over it from any direction, an alert signal is shown on the LED Display in the opposite direction, alerting the drivers. By gathering information from a cloud server, the LED Display also provides other environmental statistics, such as visibility, air quality, weather forecast, temperature and distance of nearby locations, for the immediate vicinity. Additional, cloud server can also store the data of vehicle passing through points where sensors are placed over a time span and utilize that data to calculate the traffic density and traffic volume.
