Exhibit A — Scope of Services
Supplement 2 — Tactics Database Updates
1. Task #1: Project management
Project management, meetings and administrative tasks. 52hrs
2. Task #2: Tactics Database Assessment, Review and Updates:
The pedestrian clearance timing task has revealed the need for a thorough
review of the current Tactics database. Since the Tactics system was
inoperable for severalyears, the information stored in the central database
is not consistent with the current on -street configurations. 4 hours of
additional time is needed to examine each of the 34 current intersections in
Tactics Central for accuracy, compare database configurations to
intersection configurations, and update configurations for each intersection
to ensure central database accuracy. (34x4 hrs.=128).
The pedestrian clearance timing study has created the need to modify the
signal coordination plans of 24 intersections to accommodate the additional
walk/don't walk time required for pedestrians. 3 hours per intersection is
needed to ensure that the coordination plans of each intersection will
function properly with the increased pedestrian clearance times. (24x3
hrs.=72).
City Signal staff have replaced 10 Traconex controllers with new M-60
models. Conversions of controllers can be complex, requiring site analysis
and extensive programming. These conversions warrant a configuration peer
review to ensure undocumented configurations are maintained in the new
controller conversions. (10x5 hrs.=50).
Follow-up TMC assistance to establish remote access for tech support,
Lucity integration, support and field testing. The Lucity integration requires
additional coordination meetings and field testing. 60 hrs.
