In regards to data, we will need three types of inputs: 1) facility-related
information (e.g., number of lanes, lane widths, lane configurations,
saturation flow rates); 2) traffic-related information (e.g., vehicular
and pedestrian volumes for all three conditions); and 3) operational
information (e.g., signal timings). We’ll talk about the specific data
required for each problem as it is presented. When we reach the system-wide
level of analysis, since there are unsignalized intersections on either side
of Route 146, we’ll also need behavioral information about the users such as
critical gaps
and move-up
times. We also need to know how NYSDOT designs highway facilities and
expectations for operational details (e.g., signal timings). There is some
data we won’t need, even though they might be important in other settings.
For example, we won’t need any information about on-street parking since
none is allowed along any of the streets or highways. We also won’t need
information about transit services since no bus routes pass through the
study area.
Discussion: We
decided to start the analysis with the most heavily used intersection, and
then work first west then east. What would you have done? Is there an
advantage to the way we decided to proceed? If you were doing an analysis of
the system all at once, might you miss some details if you didn't consider
the intersections individually first? What are some of the important
consistency issues you have to consider if you look at the intersections
separately?
