The problem

• Attika Region is a large and dense area of more
  than 4 million inhabitants
• Includes complex and large urban area (Athens),
  peri-urban and interurban areas Mainland and
  Islands
• Urban roads, peri-urban highways, interurban
  highways Full multi-modality urban buses,
  metro, tram, suburban railway, interurban
  railway, interurban buses, ferry boats
• Tourism gateway (Athens Airport Pireus port)
• Lack of coordinated data collection and/or
  passenger information system
• Limited and scattered historical and real time
  data

Geographical complexity
4
State of the art

• Traffic management system of Athens established
  for Olympic Games
• VMS traffic information to drivers
• Autonomous journey planners by PT operators
• Real time traffic information by private
  companies

5
Project scope objectives

• Event management (Civil protection)
• Region's Fleet monitoring
• On-site meteorological sensors, traffic counters
  VMS
• Multi-modal transport portal

• Multi-modal journey planning (combined public
  transport modes, car and pedestrian)
• Traffic conditions
• Traffic incidents
• Web map presentation POI search

6
System components

• Event management
• Monitor anomalies and catastrophies
• Event response
• Traffic engine (traffic modelling tool)
• Real time travel times
• Multi-modal journey planner
• Car, pedestrian based on travel times
• Public transport
• Combination
• Portal

System architecture

Traffic engine (MISTIC)

• Main aim to produce real time travel times
  based on continuous feed of traffic data
• Maintain reference traffic network and O-D Matrix
• Dynamic Traffic assignment
• Initial feed by EMME/2 model of 1996,
  incrementally revised to 2004 (major revision)
  and 2007
• Use of historical data and measurements for the
  calibration of model (on-going process)
• Interaction with route engine and event
  management
• Can become a City Supervisor

Multi-modal routing

• Car routing
• Shortest, fastest, cheapest
• Real time travel times update existing static
  values for the route calculation
• Pedestrian routing
• Public transport planning
• Goal algorithm
• Timetables and time windows
• Penalty for changing vehicles or modes
• Multi-modal combination
• Proximity to PT station and least walking time
• Park Ride

10
Portal

• Map data
• POIs
• Traffic information for Athens
• Public Transport timetables
• Multi-modal routes
• www.athensattica.com

Data collection

• Public transport data various levels of
  digitized data
• Greater Athens Urban area
• Real time traffic data
• Historical and model data
• Peri-urban area
• Toll-motorway Attiki odos
• Mainly model outputs to be used
• Lack of real time data
• Interurban area
• Lack of data
• Free flow routing

13
Data maintenance

• Reference network Cartographical map data
• Update of traffic model
• Public Transport timetables
• Fast incident notification
• Real time traffic feed Cater for new traffic
  management systems DATEX interfaces
• Keep track of public transport service anomalies

14
Administration framework

• 9 Public Transport operators and authorities
• 3 road authorities and operators for main
  arteries
• Over 20 local authorities for secondary roads
• 3 Ministries directly or indirectly involved
• Mostly Public Domain, but also private highway
  operators (concessions) and public transport
  fleets
• First time large scale content aggregation

15
Conclusions

• Content is the King!.
• Poor content jeopardises project's outcome. A lot
  of effort put on data validation and enhancement
• Biggest delay in project execution in data
  collection (in fact agreement for data sharing)
• Even static data is not static enough!
• Overall administration framework is required
• Extended pilot and training period (6 months)
• Beta version available from July 2008 final
  version December 2008
