Additional notes for this state
- Dirt Roads - In Connecticut all roads that are normally unpaved are considered dirt roads as this is how drivers expect the "Avoid Dirt Roads" feature to behave. These roads are shown on the CT DOT Functional Classification Maps as dashed lines.
- Toll Roads - There are currently no tolls in Connecticut. No segments within the state of Connecticut should be marked as 'Toll Road'
- Pedestrian Boardwalk and Walking Trail - These should not be mapped without approval from a State Manager for CT. These segment types can cause routing issues even when not connected to a driveable segment.
Locking standard
In Connecticut we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
