  implementation
• The system implementation process
• DSS Information presentation
• Discussion round table

4
The core of HEAVEN the DSS

• In the HEAVEN framework DSS means for Decision
  Support System
• Heaven DSS allows
• combining near real-time traffic flow
  information
• with
• environmental and noise emission models
• for
• calculating contributions of mobile sources to
  air quality and noise
• The system can operate both on-line (based on
  current traffic and environmental information)
  and off-line (based on planned traffic and
  environmental conditions)

5
The core of HEAVEN the DSS

• The HEAVEN DSS has been conceived as a tool
  suitable for
• Support decision making processes concerned with
  the definition of temporary measures as well as
  medium-term and long-term Traffic Demand
  Management Systems (TDMS), by facilitating the
  evaluation of their impacts on air and noise
  quality
• Build a common information platform on traffic
  and environment for local authorities, including
  existing and potential users
• Compile suitable information reports on traffic
  and environment to be delivered to end users
  through several media.

6
The core of HEAVEN the DSS

• The DSS general concept

7
The core of HEAVEN the DSS

• TDMS implemented in the urban area is expected to
  influence the traffic status in the network
  dynamic traffic representation forms the input
  for subsequent environmental models
• Emission models calculate traffic related
  emissions for each link of the network for a
  number of primary pollutants based on measured
  and modeled traffic characteristics
• Noise model makes use of much of the same traffic
  data input together with additional information
  about the physical built environment
• Interfaces with external monitoring systems are
  intended as data suppliers for the DSS

12
From the architecture to system development
To realize a DSS at each site starting from the
designed architecture
Purpose of system development
To maximize the commonalties between the systems
implemented at different sites
Requirement
13
From the architecture to system development
Overall System Architecture is designed to
conceptualize the DSS approach
System Architecture does not provide a real idea
about the sequential list of operations that are
performed on monitored data for providing
estimations and/or forecasts
IMPLEMENTATIVE OUTLINE
System Architecture has been translated in a
general processing chain
14
From the architecture to system development

• The DSS Processing chain

15
From the architecture to system development

• The DSS Processing chain allows to identify the
  following system components
• Interfaces of the DSS with external and/or
  existing systems
• Traffic Modelling Module
• Air Pollution Modelling Modules
• Noise Modelling Module
• Scenario and System Management Tool
• DSS Operator Interface
• HEAVEN Database

16
From the architecture to system development

• For each one of the mentioned components, at site
  level, the following details have been provided
• Characteristics of the models and sub-models used
• Type of data required
• Updating frequency for such data
• Characteristics of the exact format of data input
• Characteristics of the processing operations
  performed on the input data streams
• Characteristics of how the traffic demand
  management strategies are developed
• Characteristics of the procedures and strategy
  for integrating the data into the DSS

Discussion and Questions

• Is the DSS a technical tool feasible for your
  city ?
• Could the DSS used in your city for
  traffic-related pollution reduction ?
• Whats your opinion about the chosen system
  architecture ?
• Whats your opinion about the HEAVEN processing
  chain ?
• Whats your opinion about the used software
  components ?
