USD per capita. The design life for all central hardware and software is assumed
to be seven years; the design life of the user subsystem smart phone application
is assumed to be one year.
The approach taken toward cost estimation for intelligent sensor–based in-
frastructure assumes a scale factor of $20,000 USD per sensor connected to the
infrastructure. This includes the cost of the sensor and the communication in-
frastructure required to connect the sensor to a central back office. Sensor count
is assumed to be the total number of sensors on all road types and bus routes as
summarized in Table 11.5. The design life of seven years has been assumed to
account for changes in technology and the technology refresh at year seven.
A scale factor of $50,000 USD per mile of highway and bus routes has
been used to estimate the cost of low-cost, efficient, secure, and resilient ICT.
This is higher than the figure used for intelligent sensor–based infrastructure
as it is assumed that a larger number of devices will be connected. It is as-
sumed that the system cost will predominantly consist of telecommunications
hardware such as conduit and fiber optics and that these are less susceptible to
technology changes. Therefore, a design life of 20 years has been assumed.
