Operation of TIC 1.3 and Lessons Learned (1)
TIC NRW
Part 1

• Basic Data
• CentroMap well suited
• Additional supply of detector locations and
  kilometer-referencing not necessary for TIC
• Alternative routes, position of cross-border VMS
  and fall-back information for traffic situation
  needed as basic data with strong relation to
  CentroMap
• Filter-technology well suited
• Maintenance of basic data needs to be independent
  of software company, otherwise risk of high cost
  for maintenance
• Functionalities
• Traffic models for prediction and congestion
  analysis belong to TCC TIC only gets authorised
  information
• Traffic situation report from TCC (LOS)
• Incident messages from police TIC (AlertC)
• Road work messages from Road Authority (TRAVIN)
• TIC has main role in information dissemination to
  service provider and information exchange with
  management partners

Operation of TIC 1.3 and Lessons Learned (2)
TIC NRW
Part 1

• DATEX-links
• DATEX links are in operation
• Maintenance of DATEX links is very expensive,
  because of ISDN-cost and high effort to support
  router technology
• Relevant data sources
• Effort to operate links to internal data sources
  needs to decrease
• TCC, Police TIC, Road Authority -gt access to
  corporate authority intranet NRW (LVN)
• TIC NL, TIC F, TIC Fl could in general be
  managed by international authority intranet TESTA
  or by the Internet
• TIC Hessen, Niedersachsen, Rheinland-Pfalz -gt no
  priority as incident messages are available via
  national police TIC
• Information users
• Management partners
• TIC NL, TIC F, TIC Fl as above
• Distribution inside the authority intranet needs
  to be very flexible
• Service Providers
• To dissimenate traffic information to many
  service providers requires very easy
  dissemination approach

Operation of TIC 1.3 and Lessons Learned (3)
TIC NRW
Part 1

• Operation
• To support 2 TIC servers is too expensive
• The distributed operation by regional control
  centers Köln, Arnsberg should be continued to
  distribute work load to existing operators
• To use communication services of external network
  provider is an important requirement to ensure
  regular operation, as regional control centers
  have no staff and no budget to support
  proprietary network technology
• Other advantage of outsourcing networking to
  benefit from external Firewall solution
• Disadvantage No chance to implement
  communication solutions that are outside the
  range of communication services provided
• gt It would be fine to keep some influence on
  network provider

TIC 2.0 Access Point (1)
TIC NRW

• TIC NRW 2.0 has to serve more than 40 external
  service providers via the TIC Access Point
• filtering mechanism
• by geographical area, TMC locations, Events,
  Duration, delay, Road number
• formats TIC XML Info and TRAVIN
• TIC XML Info format is based on XML
• TIC XML Info applies the TMC location referencing
  scheme and refers to AlertC event table or DATEX
  dictionary
• exchange mechanism for TIC XML Info and DATEX
  TRAVIN
• TIC Server is automatically updating the
  information at the FTP Server
• Customer has to check cyclic if new information
  are available
• After reading the information the customer has to
  delete the corresponding file
• using FTP as the standard communication protocol
• each customer will get an FTP account including
  user name and password
• The FTP Server is accessible over the Internet.

TIC in a network for integrated visualised
information GeoView.nrw
Part 1

• Next Step
• To find a solution to visualise traffic
  information from different responsibilities
  (servers) in one map, but
• not to reduce the legal property rights of each
  responsibility
• Not to invest in basic technology development
• To be open for future ecommerce solutions
• To be open to integrate map-related information
  from neighboring domains, like weather or tourism
• Solution Geoview.nrw
• To develop an OGC-compatible web-map-server
  delivering map-related TIC-information on request
  
• To set-up a network of OGC-WMS with TIC-WMS,
  cities of Düsseldorf, Mönchengladbach, Neuss,
  Wuppertal, respective PT-operators to offer
  integrated visualised information in the Internet
• Running pilot-demonstration starts in 09/2003
