Appendix D Transportation Report - City of Oshawa

• The use of the “Synchro” software program to assess and evaluate all critical Master
Plan intersections.
The information provided above and the analysis steps undertaken follow the typical
methodology used in the completion of Environmental Assessment Study for roads and roadway
networks. The methodology included an assessment of road and plan options for the Kedron
Planning Area. The evaluation process permitted the formation of a preferred roadway structure
and network plan providing sufficient connectivity and capacity for all key modes of
transportation.
2.0 Land Use Plans
Three different land use and road network options were prepared in Phase 2 of the study. These
three plans are presented in Figures 1 through 3. The road network is very similar across all three
options. A preliminary traffic analysis was conducted on these options to determine the most
favourable option from a roadway performance perspective. The analysis and evaluation of
these options showed little difference among the options from a transportation perspective.
The preliminary analysis concluded that the collector roads shown in the options in the Part II
Plan area that run parallel to Harmony Road should be extended south to Conlin Road. These
extensions were recommended to alleviate the forecast high traffic flows on Harmony Road and
to better distribute and balance vehicle flow demands to and from all parts of the planning area.
The preliminary analysis also concluded that the North Kedron Industrial Areas should be
serviced by additional collector roads. A final conclusion of the preliminary analysis was that the
intersections along Townline road should be spaced to accommodate a potential Highway 407
interchange.
These analysis recommendations were incorporated in the design of the preferred plan which is
presented in Figure 4. The analysis presented in this report is based on this preferred plan.
The evaluation of these three preliminary options and the development of the preferred plan
followed the methodology and analysis steps of a typical Environmental Assessment (EA) Study.
As part of the EA study process a series of public meetings were conducted. A second part of the
EA study process was a review by the planning team of the three options according to the
evaluation matrices presented in the main report of the Part II Plan for the Kedron Planning Area
and the Concept Plans for the North Kedron Industrial Area + East Windfields Industrial Area.
