Traffic Mobility Information Management

• High demand for mobility in passengers and goods
  transport throughout Europe requires increased
  coordination of control policies and strategies
  at various level of the transportation network
• Enhanced coordination is required across
• different transport modes
• main urban areas, the urban/interurban interface
  and major corridors
• Fundamental role of interconnected regional
  control centres, responsible for integration and
  coordination of mobility over wide areas

MOTIC-TIC Functional Component 1
The Event Management function enables

• the handling of messages coded in different
  formats (ALERT/C, DATEX, manual input)
• the handling of obsolete, wrong or contradictory
  messages
• the combination of manual messages with automatic
  messages
• the combination of same elementary events coming
  from different sources
• the combination of events for same location and
  time
• the combination of crossborder-information making
  thus co-operative management possible
• the processing of current as well as predictable
  events

16
MOTIC-TIC Operator Console

• The information is presented to the operator by
• views of the map
• message browser
• One situation is shown by consecutive lines
  with the same color

17
MOTIC-TIC Plausibility Check 1
For those parts of the road network where a good
quality of data collection is available, it is
possible to verify congestion messages based on
this data. If proper messages are received,
i.e. different sources provide same
evidence on event they are passed through the
plausibility check.
Traffic congestion and low level of service ???
18
MOTIC-TIC Plausibility Check 1
PL-Check

• IF
• The detectors show a low level of service
  (congestion red line)
• A traffic congestion is reported
• THEN
• Accept traffic congestion info

Low level of Service and traffic congestion is
acceptible !
19
MOTIC-TIC Plausibility Check 2
For those parts of the road network where a good
quality of data collection is available, it is
possible to verify congestion messages based on
this data. If improper messages are received,
i.e. different sources provide
contradictory evidence on event they
are not passed through the plausibility check.
Traffic congestion and free traffic flow ???
20
MOTIC-TIC Plausibility Check 2
PL-Check

• IF
• The detectors show a good level of service
  (free flow green line)
• A traffic congestion is reported
• THEN
• Reject traffic congestion info

Good level of Service and traffic congestion
should be impossible !

  to give an intermodal rerouting advice to be
  distributed by the service providers

MOTIC-SMC Functional Capabilities
The Strategic Management functionalities enable

• the generation, simulation and analysis of
  scenarios to support strategic traffic and
  mobility management operations, including
• analysis of recurrent congestion problems in
  the network
• planning strategies to face expected anomalies
  in - transport supply (e.g. network capacity
  problems, bad weather, road works etc.)
  or - transport demand (e.g. special events like
  fairs etc. )
• definition and evaluation of new strategies to
  adapt transport supply (network capacity,
  parking capacity, multimodal offers etc.)
• analysis of traffic control strategies (e.g.
  VMS or RDS/TMC messages etc.)
• the use of online data as well as historic
  patterns or predictions

MOTIC-SMC Traffic Scenario Management
With the help of the Traffic Scenario Management
Tools, the operator may

• Implement a Traffic Scenario via a Graphical User
  Interface
• Adapt a Traffic Scenario to the current /
  historic traffic situation - adapt the demand
  (OD matrix) to traffic data - adapt the
  scenario description - e.g. state of supply -
  according to current, historic or predicted
  events
• Simulate the Traffic Scenario with the Getram /
  AIMSUN2 microscopic simulation environment
• Analyse the results

MOTIC-SMC Scenario Adaptation to On-line Data

• Scenario adaptation to on-line traffic data
  collected by sensors, related to
• the scenario area
• the scenario time period
• Adaptation includes
• computing the traversal O/D matrix for the
  scenario area, given an O/D matrix for the entire
  network
• adjusting the local O/D matrix to reflect traffic
  counts in the area from the previous detection
  period
• Obtained by a model developed by UPC, Barcelona
• mathematical programming approach (bilevel
  programming)
• computing a sequence of O/D matrices iteratively
  reducing the least square error between
• (1) traffic counts from detectors and
  (2) the traffic flows obtained by assignement of
  the O/D matrix in the scenario area

36
MOTIC-SMC Scenario Adaptation to On-line Events

• Scenario adaptation to on-line mobility events
  collected by messages, related to
• the scenario area
• the scenario time period
• Adaptation includes updating the scenario
  description in relation to
• network state and conditions, e.g. capacity
  restriction due to roadworks, ...
• supply state and conditions, e.g. PT lines
  breakdown, parking / PR facilities
  conditions,...

  Knowledge Based tool
• Integrated within the MOTIC-SMC, TRADAS
  supports
• traffic situation definitions as frames
• frame based reasoning i.e. interpretation of
  scenario data by matching of the frames KB
  against data (supplied after scenario simulation)
• classification of traffic situations with
  uncertainty (certainty measure)
• graphical presentation of matching situations

42
MOTIC-SMC Scenario Analysis

• MOTIC-SMC Situation Frames
• 1. support a structured organisation of
  knowledge according to network topology
  (objects hierarchy)
• 2. are defined by
• sets of slots
• slots identify traffic engineeringconditions to
  build up interpretationsof the traffic situation
  in the area
• slots represent linguistic variables e.g.
  traffic-density can be low, normal, high
• each slot has an attached determination ruleto
  compute its value
• support of generalised quantifiers (SOME MOST
  ALL) e.g. if MOST sections are highly
  loaded, then sub-network is highly loaded
