4.2.3 Road Section Operations
The key road sections have been analyzed under 2030 background conditions for the critical PM peak
hour, with respect to capacity. The resulting volume to capacity ratios are presented in Table 17.
The analysis of the 2030 background traffic volumes reveals that most of the road sections assessed
will operate at 98% or less of the assumed road capacity (ie. the volume ÷ capacity is ≤ 0.98), the
exceptions being First Street, Hume Street and Hurontario Street. Although congestion may occur as
the volume to capacity ratio surpasses 0.90, this only occurs during the PM peak hour. It is also noted
that the intersection operations are considered a key indicator of the capacity of a road network given
that an intersection represents the ‘pinch points’ or ‘bottlenecks’ of the network. When considering the
recommended intersection improvements for the 2030 background conditions, the key intersections
offer adequate levels of service. As such, the available capacity is considered appropriate from a
traffic operations perspective and therefore no additional lanes to increase road capacity are required
to support the 2030 background conditions.
On First Street, the volumes will exceed the noted capacity by approximately 8 to 11% during the PM
peak hour. However, in consideration of the increased through capacity resulting from the provision of
the centre turn lanes, the volumes can be accommodated.
With respect to Hume Street, the discussion provided in Section 4.1.3 holds true. The future planned
improvements are expected to offset the capacity concerns presented by the link volumes. Additional
lanes are therefore not recommended to accommodate 2030 background conditions.
The volumes on Hurontario Street are expected to slightly exceed capacity south of First Street. As
the main street through the downtown core, Hurontario Street is constrained by the surrounding
development, on-street parking and pedestrian infrastructure. As such, the provision of additional
lanes is not feasible or recommended. Rather, as congestion occurs traffic will seek alternate routes if
necessary to avoid the congested areas.
