  2. Click the Show Details button associated with the desired ESU . This opens the NSG form in another browser tab.

  3. Click the ESUs (Type 13) Tab.

Elementary street units (ESUs) are subsets of Streets forming a continuous length. Primarily, they are recorded to relate the Street reference to a physical extent.

ESUs also enable the construction of Street network topology. They are primarily junction to junction (or end), but sometimes they end at other points.

The ESUs tab also allows you to define One Way Exemptions and Highway Dedications.

A One Way Exemption can be used to record contra-flow lanes where one type of traffic is allowed to travel in the opposite direction from the one-way restriction, for example buses.

A Highway Dedication defines which type of Highway user has access to that particular section of the Highway.
