Generic MUTCD Location Marker- New Feature

[sergebeaudry]

Summary

Add a new Marked Location to the DeviceFeed that represents any MUTCD standard temporary Traffic Control zone signs as defined per the MUTCD standard. Ref: Table 6F-1

Motivation

Currently the DeviceFeed includes many Location Markers and the list keeps growing over the feed iterations. The ultimate goal of the feed is to become a real-time digital representation of the physical work zone. A typical work zone has many standardized temporary traffic control signs and each represents critically important information such as location of the work zone, lower work zone speed changes, closure, shift, etc... Each of those sign has a specific MUTCD code that is standardize such as the following.

By adding a few more elements to the current LocationMarker object this would allow future solutions to potentially fully digitize a job layout and transmit it using WZDx DeviceFeed. Applications are multiple including quality control, job conformity, inventory management, real-time road impacts to connected car or digital map, etc....

Proposed changes

Add mutcd-sign to the MarkerLocationType enumerated type, which is part of the LocationMarker - MarketLocation object

Add the following properties to the LocationMarker Object: Others ideas welcome

• MUTCD_Sign_Designation: String, required only if MarkerLocationType is mutcd-sign. Represent the official MUTCD code as per current standard. EX: G20-05aP for a work zone sign, R11-2 for Road Closed
• MUTCD_Sign_Name: String, optional. Represents the official MUTCD sign name. To make the feed easier to read.
• MUTCD_Sign_speed: Integer, optional. Every speed sign has the same MUTCD Designation which is R2-1.
  
  to differentiate a 40, 55, 65 MPH this field would be offered to complement the sign designation info
• MUTCD_sign_direction. Choice: Left, Right. Optional. Some MUTCD signs such as W1-6
  
  are used for both directions. They simply flip it over at the installation. This field will provide a way to specify in which direction those are pointing if known.
