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

Slide 31

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.
