Goals and Objectives
purposes of the case study, we’re going to assume the goal is to
mitigate negative impacts resulting from traffic related to the site and
general background traffic growth. We have to separate the former from the
latter to ensure that we know which impacts are due to general traffic
growth and which are due to the site. The objectives are to identify the
improvements in geometry and the operational changes required. The
former is likely to be lane additions while the latter is likely to be
changes in lane use designation and signal timing.
Related to the goals
and objectives are performance measures by which the system’s performance is
evaluated. In many cases, they’re easy to identify. Delay is one that’s
common. Another is level of service (LOS). (Sometimes delay implies level
of service.) Others are total vehicle hours of travel, total vehicle
miles, air pollution outputs, and noise impacts. For this case study,
we will focus on delays and queues.
will we need to model to address these goals? What other potential issues
may need to be addressed as part of this development?
