9.2.3 - Determine M&C Needs DFD

This DFD shows the processes that provide the Determine M&C Needs facility within the Manage Roadway M&C Activities function. These processes identify equipment requiring repair, winter maintenance needs, resource requirements, and then request maintenance and construction work to be scheduled. They coordinate M&C resource needs as part of planning for disaster response or evacuation. An automated Maintenance Decision Support system function is also supported.

The key points about the facility are:

Equipment repair, winter maintenance, and routine roadway maintenance needs are determined;
Resource needs from other agencies are collected and resolved;
Disaster response or evacuation plans are coordinated with emergency management;
Maintenance Decision Support system makes maintenance recommendations based on current weather, needs, and resources available with parameter input from center personnel.

There are seven processes in this DFD:
a) Determine Winter Roadway Treatment Needs (9.2.3.1)
b) Determine Roadway M&C Needs (9.2.3.2)
c) Provide Maintenance Decision Support (9.2.3.3)
d) Manage M&C Resource Needs (9.2.3.4)
e) Collect Roadside Equipment Status (9.2.3.5)
f) Collect Field Equipment Status for Repair (9.2.3.6)
g) Process Environmental Probe Data for Maintenance (9.2.3.7)

The processes in this group provide all the facilities for determining maintenance and construction needs, from roadside equipment repair, to winter and routine maintenance, to handling resource requests from other agencies. All except process (c) work together, although (a) could be omitted if winter roadway treatment is not required in the implementation. Process (c) is used in more advanced applications in which specific maintenance and construction recommendations are produced automatically, without personnel intervention except for system parameter inputs.
