Layers of Transportation Data(Source: ArcGIS UNETRANS Data Model)

• The Events Layer – contains objects such as vehicles moving across the network.

• The Routing Layer – contains more complex features such as “No exit”, e.g. at the intersection of a bridge and tunnel.

• The Reference Network Layer – contains all of the base road data . This data has a linear spatial representation and has an underlying topological structure that defines the connectivity and adjacency of links in the road network.

Conclusions (1)

• The HA’s Business Capabilities as a Network Operator are essentially:• The collection and dissemination of data

• Strategic Preparation of the Network• Roadworks and pre-planned event management

• Demand Management

• Network Resilience

• Traffic Operations• Traffic Management

• Incident Management

Conclusions (2)

• The Traffic Information Architecture (Capabilities) comprises:• The Unified Road Network Model

• The Reference Network Layer, and

• The Routing Features Layer

• The National State of the Road Network• The Events Layer

• The Technical Architecture (Capabilities)• Geographic Information Systems (GIS)• Service-Oriented Architecture (SOA)• Complex Event Processing (CEP)• Real-time Publish & Subscribe (ESB)
