Guidelines for the Preparation of Transportation Impact Studies - 8th ...

4.4 Background Changes in Traffic and Transit Conditions
4.4.1 Provide a summary of adjustments to existing traffic and transit volumes to account for
developments which were under construction, or constructed but not fully occupied, when
the traffic counts were undertaken, or which have since been abandoned or demolished.
4.4.2 Provide an assessment of cumulative traffic and transit ridership changes associated with
other development proposals in the study area which have been approved or which, in the
judgement of HRM planning staff, will likely be approved before the development
proposal in question.
Consultation with Halifax Regional Municipality staff will be useful in identifying
other development or redevelopment proposals that should be accounted for in the
TIS. In general, the objective should be to attempt to reflect the expected
conditions at the time the development will be completed and occupied.
4.4.3 An assessment of traffic and transit ridership changes resulting from development beyond
the study area and the ongoing growth of travel across the region and through the study
area is needed. In general, observed growth trends or future projections based on area
transportation studies or modelling can be used. In some situations, alternative
assumptions or methods, such as the application of development absorption rates, may be
appropriate.
4.4.4 Where a land-use or transportation plan is in place that establishes a transportation context
for the area, it should be possible to streamline or simplify dealing with such issues as
background traffic and transit ridership changes.
