3.How to enter your communitys data
Slide 3
ITD Statewide Customer Satisfaction Survey 75% of respondents:
safe biking is important
Slide 4
Project Goal: Create GIS tools to assess comfort and safety of
bicycling. Purpose and Scope: To help engineers and planners
prioritize improvement projects.

Bicycle Suitability Perceived comfort and safety of a linear
section of bikeway (streets and shared-use paths) Bikeability
Perceived comfort, safety, and convenience of an entire bikeway
network to access important destinations (community-wide) Bicycle
Friendliness General perceptions about all aspects of bicycle
travel, including bikeability, laws and policies to promote biking,
education efforts to encourage biking, and general acceptance of
bicycling throughout the community

[The next section of the video uses ArcGIS. The following
slides outline the material.]
Slide 20
Introduction Look at files using Explorer Look at files using
Catalog Look at Example Files in Catalog BLOS Tool Pull in Streets.
Open attribute table. Look at Interface and Help for Calculate BLOS
Execute Calculate BLOS Look at new output attribute table BSL and
BSS Tools Execute Calculate BSL. Execute Calculate BSS.
Slide 21
Other BLOS Tools Execute Calculate BLOS again, comment on
warning for already existing fields Look at other BLOS tools Return
to powerpoint
Slide 22
Street Intersection Travel Direction Facility
Slide 23
BLOS Tools Execute Calculate BLOS Intersection Execute
Calculate BLOS Facility Comment on Data Preparation Tools Execute
Create Intersection File, Open Attribute Table Pull in Pathways
Execute Calculate BLOS Pathway Bikeability Explanation Pull in
GroceryStore_destinations Review the concept of Bikeability Execute
Append for Pathways to Streets and call it bikeways.
Slide 24
Bikeability Tool Pull in Zones. Pull in grocery store
destinations and explain. Execute Calculate Community-wide
Bikeabilty for existing grocery stores. Pause because takes 6 (5.5)
minutes on my laptop computer. The report discusses execution times
for different zone sizes. Return to ArcGIS. Look at last few
seconds and explain what is happening. Look at results. Discuss
good bikeability areas. Execute again for proposed grocery
store.
Slide 25
Scenario 1: Existing Grocery Stores Scenario 2: With New
Grocery Store
Slide 26
Scenario 1: Without New Bike Path Scenario 2: New Bike
Path
Slide 27
[Return to ArcGIS.]
Slide 28
Bikeability Tools Pull in, open, and look at parcel file, but
dont Execute. Execute Identify Probable Routes to a Destination Jr.
High school using zones. Execute Identify Probable Routes to a
Destination Jr. High school using student addresses. Statistic Tool
Execute Statistic tool for all three.
Slide 29
Slide 30
Create Zones Tool Execute Create Analysis Zones. Note that
smaller zones will require more time. Create Streets File Execute
Create Streets File Look at blank attribute table. Note street
class Look at streets that are isolated or outside of study
area

Correct Topology Incorrect Topology
Slide 32
[Go to arcgis.com help. Search Topology, look at Topology
basics. Explain. Search Topology errors, look at Geodatabase
topology rules and. Explain there are few existing tools to help
create topology. Return to powerpoint to show Create Street
File.]
Slide 33
Enter Data Look at table in excel. Execute Enter Data and look
at output.
