6.1 Preprocessing Required
6.11 Add Seconds field to Street centre-line theme
- Added a field to the Street centre-line theme called Seconds that
reveals on average, how long it takes for a Fire truck to travel along
it. The average speed of the Fire truck would travel approximately
75 km/hr, as notified by the Fire Chief of Firehall #5. The speed
is a rough estimate at best and takes into some consideration, the time
of day, the amount of stop signs, and the type of road.
6.12 Add Alternative Proposal location for Firehall #5 to Places
theme
- Placed an additional point to places theme to represent the alternative
proposal for Firehall #5. The location was based on analysis done
before hand and took into consideration details from the City map of Burnaby
as well as the Firehall map. I was aware to place it near schools
with high density student population as well as at busy streets and commercial
areas.
6.2 Calculate Service Area and Service Network
6.21 Existing Firehall #5
- Used Arcview Network Analyist. I preselected FireHall #5 then
chose Find Service Area from the Network menu. Selected Travel-to-Site
then I loaded the Place theme that has FireHall#5 already selected.
Finally, I selected Seconds for the Cost Field and Solve to generate the
service area and service network.

6.22 Proposed Firehall #5
- Used Arcview Network Analyist. In applying the same procedures
as in calculating the service area for the existing Firehall, this is the
resulting service area and service network.

6.23 Alternative Proposal Firehall #5
Calculate Interpolate Grid from Student Population
- Used Spatial Analyist. Before starting the analysis procedures,
I created a field in the places theme that contained the population for
each school. I named it Z-value. I then chose Interpolate Grid
from the Surface menu. In the OutputGidExtent section of the OutputGridSpecification
section, I chose Same-as-View. I then chose IDW as the method and
chose Z-value for the Z-Value field both from Interpolate Surface.
The following reveals the last menu before interpolation was applied and
the Interpolated Surface.
Interpolate Grid for Student Population
- Used Arcview Network Analyist. In applying the same procedures as in calculating the service area for the existing and the propsed Firehall, this is the resulting service area and service network.

6.3 Calculate Shortest Route
6.31 Existing Firehall to Alpha Secondary & Burnaby North Secondary
- Used Arcview Network Analyist. I preselected Firehall #5 and
Alpha Secondary then I highlighted the Street-Centre line theme.
Finally, I chose Find Best Route from the Network menu. Selected
Load Stops then I loaded the Place theme that has Firehall #5 and Alpha
Secondary selected. Then I selected Seconds for the Cost Field and
Solve to generate the route. The same procedures were applied to
locate the shortest route to Burnaby North Secondary.
Shortest Route from Existing Firehall
6.32 Proposed Firehall to Alpha Secondary & Burnaby North Secondary
- Used Arcview Network Analyist. In applying the same procedures
as in calculating the shortest route for the existing Firehall, this is
the resulting shortest route.
Shortest Route from Proposed Firehall
6.33 Alternative Proposal Firehall to Alpha Secondary & Burnaby
North Secondary
- Used Arcview Network Analyist. In applying the same procedures
as in calculating the shortest route for the existing Firehall, this is
the resulting shortest route.
