Add Disasters Enumeration

[DeraldDudley]

Summary

• This requests supports Add Incident EventType #13
• The Disasters Enumeration will fill the type_of_incident property to let drives know why a road has been detoured, restricted, or closed.

Motivation

Adding the type_of_incident property to the IncidentRoadEvent object lets data publishers tell drivers why road access has been detoured, restricted, or closed. Further, implementing this property adds value to road event feeds by reducing driver uncertainty.

Description

The type_of_incident property emulates the cause element found in the eventDescription property described in section 3.3.8.14 of the Transportation Management Data Dictionary 3.1 (TMDD). The type_of_incident property will be populated using the accidentAndIncidents,Disasters, Special Events, and Winds enumerations described in sections 3.6.5.1, 3.6.5.8, 3.6.5.23, 3.6.5.37 respectively.
