Figure 11 – VehicularAccess class diagram

AccessType enumerations (AccessTypeEnum) for VehicularAccess support the definition of characteristics for the how vehicles flow to, from and both to and from a place or part thereof respectively (denoted by the flow attribute, using the AccessType enumerations). Each of the AccessLaneType enumerations (AccessLaneTypeEnum) may support the definition of characteristics for each lane within the instance of VehicularAccess. Preferred practice gives a sequence number to each lane left to right when entering the facility.

VehicularAccess also supports a macro view of access by enabling an entity to reference access or approaches to a facility by defining primary roads near the place and/or identifying primary routes from a highway and/or nearby significant crossroads to define approximate location of the vehicular access point. This is accomplished via instances of Road and RodeNode classes, see Figure 12.
