Evaluation
   Elements
    – Assessment of Public’s view on effectiveness
      of system
    – Assessment of partner agencies perception of
      ITMS
    – Assessment of decision-maker’s perception of
      ITMS
    – Assessment of ITMS’s operational
      effectiveness
      • Effects of ITMS on travel delay during construction
