Problem
Reckless driving and poor weather conditions are one of the major reasons for most of the road accidents. Annually more than 6 million car accidents happen due to poor weather conditions and rainfall in the US. The problem is 10 times more critical on a global scale. Adverse weather situations reduce road visibility and in particular weather conditions, the roads are slippery, which further increases the chances of accidents. Exposure to critical air quality levels in tunnels, parking lots, and crowded streets leads to serious health hazards. It is necessary to take preventive actions and avoid vehicular congestion, which are the hot-spots of heavy emissions.

Concept
Roadside monitoring of weather parameters from strategic locations can address the problem of accidents due to poor weather conditions. Weather monitoring solutions capturing the target parameters should be installed at specific intervals on the roadways to gather data. The data can be used to derive dynamic speed-limit which should be enforced using a speed-control system. Air pollution monitoring at crossroads, tunnels and multi-level parking facilities is critically important for ensuring health and safety within the transportation networks. Actions like adjusting tunnel ventilation intensity, traffic lights regulation, etc. can greatly limit the exposure to high levels of emissions and restricting access to basement parking when needed.

Target Parameters
Road Dust (PM2.5 & PM10)
Vehicular Emission (SOx, NOx, CO)
Road Visibility
Road Surface Temperature
Rainfall
Noise

Proposed Solution
Oizom Weathercom is proposed to be installed at accident-prone zones on the highway. The intelligent road sensors monitor critical parameters like road visibility, road surface temperature, and rainfall in real-time. Oizom Polludrone needs to be installed at crossroads, tunnels and multi-level parking facilities to monitor vehicular emission. Weathercom and Polludrone push the real-time data obtained to the Oizom cloud. The top-speed limit is calculated based on weather speed index. The dynamic speed limit is then served to the drivers in the form of push notifications through maps, and Visual Messaging Displays. Effective vehicular route management is performed in case of higher pollution levels. Tunnel and parking ventilation are automated based on the pollution level.

Impact
Integrating weather and road condition monitoring into Intelligent Transport Systems (ITS) helps in reducing road accidents by 12-16%. Air quality monitoring on the roadways and tunnels ensures human exposure to vehicular emission is within the permissible limits. Automation of the ventilation manages the air circulation and improves the air quality inside tunnels and multi-level parking facilities.
