This report provides a review of several implementations of ICM and documents lessons learned and best practices. 1  Within this document, a Capability Maturity Model (CMM) approach is defined. This provides a disciplined process to address varying levels of maturity of six core building blocks of an ICM (Figure 11). This process is recommended to address data fusion needs:

  • Level 1: Individual agencies have data on their systems, and some sharing is done either through a data feed or manually.
  • Level 2: Multiple agencies have near real-time data, which is provided to the travelers in the corridor; however, the data is not centralized.
  • Level 3: Multiple agencies have near real-time data, which is integrated into a central data system and provided to the travelers in the corridor. Data is only one way; agencies provide data to the central system, but do not receive fused data from the central system.
  • Level 4: Multiple agencies have near real-time data, which is integrated into a central data system and provided to the travelers in the corridor. Data is provided to the agencies, so that their operational systems are updated with fused data.
  • Level 5: Multiple agencies and modes have near real-time data, which is integrated into a central data system and provided to the travelers in the corridor. Data is provided from both private and public sources and fused together to provide more coverage of the entire corridor. Data is provided back to the agencies, so that their operational systems are updated with fused data.
