Lesson Learned

This study found a wide range in costs for the APMS projects at BWI airport, Seattle Center and Chicago Metra park-and-ride facilities (ranging from $250 to $800 per space). The factors that had the greatest affect on cost included: type and level of accuracy of the information provided; degree of complexity in installation of the sensors; availability of communication channels; availability of power supplies for remote components, and the signage required to convey the information at appropriate decision points.
  • At BWI, the unit cost of the equipment was approximately $450 per parking space. BWI stakeholders estimate that the system would have been more expensive if an existing facility had been retrofitted with the system’s equipment. THE APMS was estimated to cost between 2 and 5 percent of the overall construction cost of the new parking facility (excluding land costs).
  • In Seattle, the cost per space varied widely depending on the facility type (garage or surface). The overall cost was driven to a large degree by the cost of getting the signs installed and linked to the central computer and to local power supplies.
  • For the Chicago project, Metra will have a two year warranty period when the system becomes operational, during which time it will document operational costs such as staff time and materials. Metra expects that the annual electrical costs will be approximately $1680 to operate the seven signs.
When estimating costs for APMS projects, managers should consider the factors most likely to affect cost, including the type and level of accuracy of the information provided, the complexity of the installation, the availability of communications and power lines, and the signage required.
