Task Description

AWOS (Automated Weather Observing Systems), ASOS (Automated Surface Observing Systems) and RWIS (Roadside Weather Information Systems) equipment provide similar meteorological information to support safe and efficient transportation across multiple modes, but are operated independently of each other. Continued deployment and operation of similar but independent systems in close proximity to each other may result in redundancy and increased costs. The goal of this project is to identify, quantify and demonstrate the benefits, costs and institutional issues associated with AWOS (Automated Weather Observing Systems) /ASOS (Automated Surface Observing Systems) and RWIS (Road Weather Information System) data linkage and the potential for cooperative maintenance and deployment of such systems.  This project will help Caltrans to enhance its ability to provide airport managers, air traffic controllers, pilots, and related operators of air ambulance services with more comprehensive and accurate meteorological data by integrating currently used weather systems with systems used by related agencies.  Anticipated general benefits include improved safety and increase efficiency.

Task Objective

The goal of this task is to identify, quantify and demonstrate the benefits, costs and institutional issues associated with AWOS/ ASOS and RWIS data linkage and the potential for cooperative maintenance and deployment of such system.  The objectives are:
1. Identify aviation industry needs, requirements and benefits, compare current capabilities, costs, coverage, and operation and maintenance requirements of AWOS / ASOS and RWIS by respective agencies.
2. Summarize lessons learned from similar integration projects.
3. Conduct a cost-benefit analysis for both and integrated data system and for cooperative maintenance and deployments and controlled field demonstration prototype system.
4. Create a controlled field demonstration prototype system.
5. Evaluate the controlled field demonstration prototype system.
6. Make recommendations based on the cost-benefit analysis and the evaluation of the field demonstration prototype system.
