Figure 1 – Proposed Development Location
• Research focus: Analyzing the impact of a new development at 7-
15 Steeles Avenue East

transportation (e.g., buses, walking), traffic volume analysis, and
predicting future traffic patterns resulting from the new
development

10. Traffic Analysis and Future Traffic
Peak hour Factor Calculation:
• AM and PM peak factors are determined by comparing the highest 15-minute traffic
volume to the average traffic volume during respective peak hours.
• Formulas: Peak hour factor = Average traffic volume / Total traffic volume.
• In our case, AM Peak hour values are used to calculate the traffic volume .
• We got peak hour factor as 0.82.
Future Traffic Calculation:
• Growth factor calculation: Growth factor = (1 + r)^n, where r represents the annual
growth rate (2% to 5%) and n is a multiple of 5, representing the number of years.
• Background traffic calculation: Background traffic = Growth rate * total traffic
• We assume Growth rate =2% & No. Of Years = 5 years
• In our case, Growth factor =1.10

12. Traffic Analysis
The proposed building is a tall building of 50-storey building, with a total of 683 residential dwelling units and 171 m2 GFA
of retail on related ground floor.
a. According to ITE Manual Sheet for the Land use code220 (Apartment) for A.M. Peak Hour, One Hour between 7and 9
A.M.:– 20% entering, 80% exiting, 0.51 Trip Generation Rate per Dwelling Unit.
b. Here we have 683 dwelling units , so 0.51*683=348 trips generated Of which 20% entering = 0.2*348 =70 trips 80%
exiting = 0.8*348 =278 trips
c. Out of exiting trips , we assume 80% of 278 are joining the Steeles and Yonge intersection and 20% trips joins the Steeles
Ave & Dudley .
d. Considering the Yonge & Steeles intersection, assume equal number of 74 trips turn to each direction approaching from
proposed building.
e. Similarly the Steels & Dudley intersection, assume equal number of 9 trips turn to each direction approaching from
proposed building.
f. Out of entering trips , we assume 80% of 70 are coming from the Steels and Yonge intersection and 20% trips coming
from the Steeles Ave & Dudley .
g. Considering the Yonge & Steeles intersection, assume equal number of 18 trips turn from each direction towards
the proposed building.
h. Similarly the Steeles & Dudley intersection, assume equal number of 5 trips turn to each direction approaching from
proposed building.

16. Study Findings and Conclusions
Traffic Generation:
• The traffic volume and future traffic (Veh/hr) are estimated high in all directions.
• The LOS of the intersection is marked C & D indicating we have traffic and need to implement
measures to reduce congestion.
Impact on Traffic Delay:
• Expected delay time of 32 sec.
• impact on the current transportation network anticipated.
Transit Impact:
• High transit demands projected from the development.
• Noticeable effect on existing transit service anticipated.
• Future Yonge Steele Subway station expected to accommodate the development's transit
demands.

17. Study Recommendation
• Transportation Demand Management (TDM):
• Implement measures and incentives promoting active transportation and transit,
reducing single-occupant-vehicle trips.
• Pedestrian and Cycling Connections:
• Establish direct shared pedestrian and cycling connections from the development to
Steeles Avenue as appropriate.
• Implement fixed signal timing for intersections
• Promote the use of public transport – Yonge and Steele’s subway – in a 300 m walk from
the site proposed.
• At Steels and Yonge, add Actuated signal system for left turning vehicle.
• The future through traffic in main intersection is high so addition of a lane can be
implemented.
