The Work Zone Data Exchange (WZDx) Specification aims to make harmonized work zone data provided by infrastructure owners and operators (IOOs) available for third party use, making travel on public roads safer and more efficient through ubiquitous access to data on work zone activity.

Update RestrictionType.md to include road restrictions such as reduced-speed, shift-left, and shift-right #327
Added road restrictions to handle situations where vehicles are required to reduce their speed or shift lanes in order to avoid roadside hazards.
Impact of Changes
A RestrictionRoadEvent can now be created to warn drivers about restrictions placed on a particular roadway to ensure their safety due to roadside hazards such as a vegetable oil spill, objects which can puncture tires such as nails or screws, first-responders parked on the side of the road in response to an accident scene, or the presence of black ice on a roadway.
Enhanced Information about Changes
The parent Restriction object contains an optional "Number" field which can be used to indicate the number of lanes a vehicle must shift-left or shift-right, or the number of MPH at which a vehicle must drive as a reduced speed. Thus, the simple restriction types of shift-left, shift-right, and reduced-speed can be enhanced with information specific enough for drivers to alter their behavior.
