Who are we?

• Rapidis ApS was formed january 1st, 2003
• Focus GIS-based solutions for Transportation
  Industry
• Produces software solutions based on ESRI GIS
  advanced calculation tools
• Participates in a number of planning projects,
  providing software

Transportation Models GIS

• Who uses them?
• Departments of transportation
• Public Transport authorities
• Consultants
• Transportation models are used to support
  decision making
• Transportation consequences of land-use changes
• Forecasts of traffic flows
• Providing basis for detailed environmental impact
  assesments
• Evaluating planning scenarios
• Evaluating infrastructure changes
• Assesing impact on travellers of disruptions
• Etc.
• Examples
• Examine the consequences of a new by-pass road
• Whats the impact of a new housing development on
  the transportation system?
• Consequences of improving the public
  transportation system
• What will happen if the number of parking lots in
  the city centre is doubled?

Transportation Models GIS

• Traditionally GIS has been marginal to
  transportation modeling
• Used for some editing and visualization
• Calculations performed in external applications
• Lots of import/export operations, due to
  proprietary formats
• ArcGIS has changed this
• The ability to use relational databases
• Good data management features
• Support for producing complex data models,
  including relationships, networks and topology
• Platform for software development using standard
  tools
• Geoprocessing, building and executing calculation
  processes
• ArcGIS now support all stages of transportation
  modeling work

ArcGIS Transportation Modeling Traffic Analyst

• Traffic Analyst - An ArcGIS extension
• focusing on transportation modeling
• Geoprocessing tools
• Editing tools
• An underlying data model

7
ArcGIS Transportation Modeling Traffic Analyst

• An Example a transportation model
• How many wants to travel?
• What are the destinations?
• What are their mode of transportation?
• What are the resulting traffic flows?

Data access with Traffic Analyst

• Traffic Analyst is an extension for ArcGIS og as
  such uses the facilities in ArcGIS for data
  access. Supported formats
• Personal Geodatabase (MS Access)
• ArcSDE (on Oracle, SQL Server, DB2)
• Shapefiles og DBase
• Comma-separated text-files
• Other databases (via OLEDB read-only)

Conclusion Overall

• ArcGIS now supports all aspects of using
  transportation models
• Benefits of using ArcGIS as transport modeling
  platform
• Leverage ArcGIS features and knowledge
• Avoid work-flow and integration barriers
• Allows users flexibility and extensibility
• GIS har traditionally been marginal to working
  with transportation models
• ArcGIS Geoprocessing has the potential to make
  GIS the central platform

30
Conclusion 2, Practical results

• ArcGIS Geoprocessing has proved able to handle
  transportation models of all scales regarding
  size and complexity
• Using ArcGIS as platform for transportation
  planning and modeling work has proved to be
  cost-efficient
• A good platform for data handling management
• Improves data flows and work processes (less
  import and export between applications)
• Geoprocessing facilitates integration of existing
  calculation modules
• Easy to modify and improve complex calculation
  models
• Geoprocessing makes it easier to document complex
  calculations processes

Traffic Analyst and the Competition

• Competing software packages
• Visum from ptv (Germany)
• Cube, TRIPS from Citilabs (UK, US)
• TransCAD from Caliper (US)
• EMME/2 from INRO (Canada)
• Traffic Analyst main strengths
• Complete ArcGIS integration
• All data can be stored in any ArcGIS-supported
  format
• Every operation is performed from inside ArcGIS
• Very flexible framework for customising and
  integrating models
• Introductory Price is very competitive 7.500
