Lesson Background HTML

This document reported lessons learned during the development and deployment Decision Support Systems (DSS) and associated business rules required to operate Integrated Corridor Management Systems in Dallas and San Diego between 2007 and 2017.

Business rules are generally the game rules by which agencies and neighboring jurisdictions agree to operate. In the chess analogy, a bishop can move diagonally any number of unimpeded spaces, a pawn can move one space forward, etc.  With business rules that support interoperability between agencies and transportation corridors that span multiple jurisdictions, transportation can share data and resources to enhance their ability to monitor and predict traffic conditions, and provide actionable information to motorists.

DSS are primarily computer-based information systems and algorithms that can sort, rank, or choose alternative response actions in response to recurring and non-recurring congestion across a transportation network. DSS generally consists of three components:

  • Expert rules (configuration)
  • Prediction capabilities (modeling)
  • Evaluation (analysis)

DSS can support real-time operations as well as strategic planning over the long term to support several types of ITS applications including, but not limited to:

  • Accident response strategy assessment
  • Online travel information systems
  • Predictive travel time calculations
  • Dynamic route guidance
  • Adaptive ramp metering using predictive traffic congestion algorithms
  • Intelligence-based Transit DSS
  • Dynamic emergency vehicle routing
  • Emissions management
  • Urban and interurban congestion management
  • Security threat mitigation and large-scale evacuation management.
