232 Big Data Analytics for Connected Vehicles and Smart Cities Benefit and Cost Estimation For Smart City Transportation Services 233

Determine Benefits for Services

Service benefits are derived from prior implementation experience, assuming
that a similar level of benefit will be derived for the smart city as experienced
in previous deployments. As there are only a small number of prior smart city
deployments, previous deployments include intelligent transportation system
deployments as well as smart city deployments.

Summarize Benefits and Costs
The final step in the process is to summarize the benefits and costs in prepa-
ration for using these figures as input to decision support for service delivery
sequencing

11.5 Assumptions

Even at a sketch planning level, it is necessary to make some overall assumptions
regarding the size and nature of the smart city as the basis for a cost and benefit
estimation. A model smart city has been defined and can be described by the
parameters listed in Tables 11.4–11.6. The numbers have been selected to be
as realistic as possible, but as noted earlier, detailed cost and benefit estimates
require a detailed design exercise. Table 11.4 summarizes U.S. national param-
eters used in the cost estimation.
These figures were used as the basis for cost estimation. U.S. population
statistics were obtained from census data [2]. National figures for gas stations
[3] were proportioned according to the U.S. population.
Private car operating costs and urban truck operating costs were obtained
from the AAA website [4], assuming that an urban delivery truck would have
