Sierra Transportation Technologies provides advanced roadway weather systems that deliver precise, real-time weather and road condition data to city planners across the western U.S. These systems empower better decision-making to improve highway and freeway safety, optimize operations, and reduce weather-related crashes caused by hazardous conditions.
Road Weather Information System
Road Weather Information Systems (RWIS) consist of sensor networks installed strategically along roadways to continuously monitor environmental conditions critical to travel safety. These include road surface temperature, humidity, precipitation, and visibility. The data gathered supports transportation officials in anticipating and responding to changing conditions, minimizing risks, and improving operational efficiency.
Core RWIS Components
- Sensors: Measure key variables such as temperature, humidity, rain, and visibility directly on roadways and infrastructure.
- Data Loggers & Communication Systems: Collect and transmit sensor data quickly to transportation management centers.
- Information Systems: Analyze, visualize, and report data in formats that facilitate swift and informed decisions.
Improve Safety Through Real-Time Monitoring
RWIS provides actionable information that enables proactive roadway management:
- Detecting freezing temperatures and icy pavement to trigger timely deicing and sanding operations.
- Monitoring precipitation to guide snowplow deployment and prevent hazardous accumulations.
- Measuring visibility conditions like fog or heavy rain to support dynamic speed limits and driver alerts.
- Supporting work zone safety by monitoring conditions that may affect crews.
Manage Transportation Operations & Resources
Accurate, timely data from RWIS improves operational workflows by:
- Supporting traffic management strategies that minimize delays and congestion.
- Prioritizing maintenance activities and resource allocation based on real-time road and weather data.
- Enabling faster incident response with reliable environmental intelligence.
Economic & Operational Benefits
Investing in roadway weather systems reduces costs associated with weather-related accidents and traffic disruptions. It streamlines maintenance expenditures by focusing resources where they’re most needed, ultimately delivering safer roadways and more efficient transportation networks.
Custom Solutions For Local Weather Conditions
RWIS deployments can be customized to address regional challenges, such as flash floods in desert climates or rapidly changing mountain weather. Sierra Transportation Technologies ensures systems provide relevant and actionable data tailored to specific operational environments.
Smart City & Existing System Integration
Roadway weather system data integrates seamlessly with broader smart city initiatives and traffic management systems, providing enhanced situational awareness and supporting future-forward transportation infrastructure development.
