Automated Flood Warning Systems

General Description:
Automated flood warning systems consist of sensors that collect precipitation information that is interpreted by a computer for storage and analysis. The information can then be relayed to motorists through signs including Dynamic Message Signs (DMS) or an alarm type siren.
Effects of Solution:
¨ Increase Passenger Throughput
¨ Increase Roadway Capacity
ş Manage System Efficiency (Improves safety of a facility)
¨ Reduce Local Demand
An automated flood warning system can assist in system management, but its main objective is motorist safety.
Examples of Implementation:
See the Additional Resources section below.
Cost/Financial Information:
(Cost/financial information is estimated, and will vary based on size and scope of project, number of units, etc.)
Capital Cost
Automated Flood Warning System $40-45K
The system includes sensors (rain, water level, weather, etc.) in the field which report via radio to a central receiver/decoder, which then sends data to a base station computer for storage and analysis.
