  1. Lesson 4 Technology: Resources and Implementation

  2. Learning Outcomes • Identify the technical and institutional resources for implementing Road Weather Information Systems (RWIS) • Identify key technological resources available to you for making road weather decisions • Identify the challenges faced in implementing road weather technology

  3. Technology • Resources • Implementation Challenges

  4. RWIS • 1970s: Devices first tested on bridges • 1980s: Introduced to the general highway environment • Today: Refers to a spectrum of resources

  5. Components of RWIS • Environmental Sensor Stations • Processing Systems • Forecasts and Models • Dissemination

  6. EnvironmentalSensor Station

  7. Types of Data Collected • Air temperature • Chemical presence in roadway • Humidity • Pavement temperature • Precipitation: amount, rate and type • Other?

  8. RWIS Processing Systems 1: Road Sensors 2: Sensors & RPU 3: CPU/Server 4: End User

  9. Forecasts and Models • Air temperature • Pavement temperature • Precipitation • Wind forecast • Snow accumulation • Pavement icing

  10. FOG AHEAD Dissemination 511
