Highways and expressways are vital arteries for transportation, often carrying large volumes of fast-moving traffic. These roads frequently include tunnels and bridges, which are known to be accident-prone areas. When weather conditions worsen, the risk of traffic accidents and jams increases significantly. To improve safety and traffic management, an intelligent and efficient automatic monitoring system is essential. However, many highway sections lie in remote locations where wiring infrastructure is costly and impractical. Bivocom’s wireless monitoring solution, based on 4G/3G/GPRS cellular networks, offers a practical and effective answer to these challenges.
How Bivocom’s Wireless Monitoring System Works
Bivocom’s system focuses on monitoring both traffic flow and environmental conditions inside tunnels and on bridges. It uses wireless industrial routers that connect various sensors to a remote data center or cloud platform. These sensors collect real-time data on traffic volume, vehicle speed, particulate matter, visibility, water seepage, and ventilation conditions.
The core of the system is a wireless 3G/4G industrial router that transmits data using protocols like Modbus, Python, or MQTT. This setup eliminates the need for extensive wiring, making it ideal for remote highway sections.
Components of the Monitoring System
The system consists of several key devices working together:
IP Cameras: Provide visual monitoring for traffic and incidents.
Environmental Sensors: Detect particulate matter, visibility levels, water seepage, and ventilation status.
Traffic Flow Sensors: Measure the number of vehicles passing through the tunnel or bridge.
Vehicle Velocity Sensors: Track the speed of vehicles to identify potential speeding or slowdowns.
Bivocom Industrial 4G/3G/2G DTU or Router: Acts as the communication hub, sending data wirelessly to the control center.
Remote Data Server or Cloud Platform: Responsible for data analysis, scheduling, and displaying system results for operators.
This combination allows continuous, automated monitoring without the need for manual data collection or complex wiring.
Benefits of Using Bivocom’s Wireless Monitoring Solution
The wireless monitoring system offers several advantages that improve highway safety and reduce operational costs:
Automated Data Handling
The system automatically collects, transmits, stores, and monitors data from all field devices. This automation reduces the need for manual maintenance and lowers labor costs.
Strong Anti-Interference Capability
Designed to withstand harsh environmental conditions and electromagnetic interference, the system ensures stable operation and reliable data transmission.
Wireless Connectivity
Using cellular networks removes the need for expensive and difficult wiring in remote areas. This flexibility allows quick deployment and easy expansion.
Real-Time Monitoring and Alerts
Operators receive immediate updates on traffic conditions and environmental hazards, enabling faster response to accidents or dangerous situations.
Comprehensive Data Analysis
The cloud platform or remote server processes raw data into actionable insights, helping traffic managers make informed decisions to improve safety and traffic flow.
Practical Example: Monitoring a Mountain Tunnel
Consider a mountain expressway tunnel where weather conditions can change rapidly, causing fog and reduced visibility. Installing Bivocom’s wireless monitoring system allows continuous tracking of visibility levels and vehicle speeds. If visibility drops below a safe threshold, the system can alert traffic control to reduce speed limits or activate warning signs. Simultaneously, traffic flow sensors detect congestion early, preventing jams and secondary accidents.
This proactive approach helps maintain smooth traffic and reduces accident risks in challenging environments.
