Why AVL for Snow and Ice Control? Who would benefit? Management Operators Why AVL for Snow and Ice Control? Operators: Improve Communication Operator/Operator Operator/Supervisors Provide Updated Information Mapping Reduce operators reports Collect Data with AVL reports Why AVL for Snow and Ice Control? Management: Improve Communication Operators/Supervisors Provide Updated Information Mapping 2009 NASC 3
Why AVL for Snow and Ice Control? Management: Data Collection Amount of salt used Application rates Number of miles per route Start/End times Elements of an AVL System Collect Information Send & Receive Information Record, Store & Display Information Location Salter Temperature Wireless Systems Radio, Cellular, Satellite Data Plow up/ down Workstation Demonstration Project Key Players: Fire Department GIS Coordinator Information Services Department Equipment Operator Support 2009 NASC 4
Evaluate the options: Live AVL/GPS location Mapping Truck Equipment/Controllers Live data collection vs. downloading Transmission Cell phone Radio Key Decision Factors: Existing radio contract Voice/data agreement Radio System Provider Shared Server with Fire Department Project Software/Equipment Provider City of Dubuque - Public Works System Live AVL/GPS system 5100 Force America Controllers Collects information every 30 seconds Transmits every 2 minutes 800 MHz Radio System Voice over data 2009 NASC 5
